1 SECTION 1 Intr oduction This section gives a brief overview of the history of Programmable Controllers and explains terms commonly used in ladder - diagram programming. It also provides an overview of the process of programming and operating a PC and explains basic terminology used with OMRON PCs.
2 1-1 Overview A PC (Programmable Controller) is basically a CPU (Central Processing Unit) containing a program and connected to input and output (I/O) devices. The pro- gram controls the PC so that when an input signal from an input device turns ON, the appropriate response is made.
3 Actually there is not a total equivalence between these terms. The term condi- tion is only used to describe ladder diagram programs in general and is specifi- cally equivalent to one of a certain set of basic instructions.
4 1-4 OMRON Product T erminology OMRON products are divided into several functional groups that have generic names. Appendix A Standard Models list products according to these groups.
5 7. Wire the PC to the controlled system. This step can actually be started as soon a s step 3 has been completed. Refer to the C200HX/HG/HE PC Instal- lation Guide and to Operation Manuals and System Manuals for details on individual Units. 8. T est the program in an actual control situation and carry out fine tuning as required.
6 PC programs can be written on-screen in ladder-diagram form as well as in mne- monic form. As the program is written, it is displayed on a display , making con- firmation and modification quick and easy . Syntax checks may also be per- formed on the programs before they are downloaded to the PC.

15 2-2 PC Configuration The basic PC configuration consists of two types of Rack: a CPU Rack and Ex- pansion I/O Racks. The Expansion I/O Racks are not a required part of the basic system. They are used to increase the number of I/O points. An illustration of these Racks is provided in 3-3 IR Area.
16 2-4 Memory Cassettes The C200HX/HG/HE comes equipped with a built-in RAM for the user ’ s pro- gram, so a normal program be created even without installing a Memory Cas- sette. An optional Memory Cassette can be used to store the program, PC Set- up , I/O comments, DM area and other data area contents.
17 2-4-1 Hardware and Software Settings Th e hardware and software settings related to Memory Cassette operations are described below . Switch Settings Switch 1 on the Memory Cassette is turned OFF when the Memory Cassette is shipped. Check the setting on switch 1 before installation.
18 Use the following procedure to the UM data on an Memory Cassette to the UM data in the PC. 1, 2, 3... 1. Switch the C200HX/HG/HE to PROGRAM mode. 2. Use a host computer running SSS or a Programming Console to turn ON SR 27002 (the Compare UM to Cassette Bit).
19 2. T urn ON the C200HX/HG/HE and switch it to PROGRAM mode. 3. Use a host computer running SSS or a Programming Console to turn ON SR 27300 (the Save IOM to Cassette Bit). The data will be written from the PC to the Memory Cassette. SR 27300 will be turned OFF automatically af- ter the data transfer has been completed.
20 2-5 CPU Unit D I P S w i t c h The 6 pins on the DIP switch control 6 of the CPU Unit ’ s operating parameters. Pin Item Setting Function 1 Memory protect ON The UM area 1 cannot be overwritten from a Peripheral Device. OFF The UM area 1 can be overwritten from a Peripheral Device.
21 2-6 Operating without a Backup Battery An EEPROM or EPROM Memory Cassette can be used together with various memory settings to enable operation without a backup battery . The following conditions must be met. 1, 2, 3... 1. The user program must be written to an EPROM or EEPROM Memory Cas- sette.
22 1, 2, 3... 1. Allocate U M area using the SYSMAC Support Software (SSS) if you want to us e Expansion DM for Special I/O Units or if you want to store I/O comments in the PC. 2. Write and transfer the user program, including a line using the Always OFF Flag (SR 25314) to ensure that the Output OFF Bit (SR 25215) remains OFF .
23 SECTION 3 Memory Ar eas V arious types of data are required to achieve ef fective and correct control. T o facilitate managing this data, the PC is provided with various memory ar eas for data, each of which performs a different function. The areas generally accessible by the user for use in programming are classified as data areas .
24 3-1 Introduction 3-1-1 Data Area Overview Details, including the name, size, and range of each area are summarized in the following table. Data and memory areas are normally referred to by their acro- nyms, e.
25 some flags can be turned ON and OFF by the user , most flags are read only; they cannot be controlled directly . Control b its are bits turned ON and OFF by the user to control specific aspects o f operation. Any bit given a name using the word bit rather than the word flag is a control bit, e.
26 An actual data location within any data area but the TC area is designated by its address. The address designates the bit or word within the area where the de- sired data is located. The TC area consists of TC numbers, each of which is used for a specific timer or counter defined in the program.
27 When inputting data into data areas, it must be input in the proper form for the intended purpose. This is no problem when designating individual bits, which ar e merely turned ON (equivalent to a binary value of 1) or OFF (a binary value of 0).
28 Signed Binary Signed binary data can have either a positive and negative value. The sign is indicated b y the status of bit 15. If bit 15 is OFF , the number is positive and if bit 15 is ON, the number is negative.

68 Setting Function Mode 11 C200H-compatible ROM Mode 2 The contents of DM 7000 through DM 8599 are transferred to DM 1000 through DM 2599 at startup and DM 1000 through DM 2599 are used for the Special I/O Unit Area. • The UM Area Allocation operation must be performed beforehand.
69 Once defined, a TC number can be designated as an operand in one or more of certain set of instructions other than those listed above. When defined as a timer , a TC number designated as an operand takes a TIM prefix. The TIM prefix is used regardless of the timer instruction that was used to define the timer .
70 3-10 UM Area With the C200HX/HG/HE PCs, the UM area contains the ladder program. Part of the UM area can be allocated for use as expansion DM or the I/O comment area. Th e usable size of the UM area ranges from 3.2 KW in the C200HE-CPU1 1-E to 31.2 KW in the C200HX-CPU 4-E.
71 3-1 1 TR (T emporary Relay) Area Th e TR area provides eight bits that are used only with the LD and OUT instruc- tions t o enable certain types of branching ladder diagram programming. The use of TR bits is described in Section 4 Writing and Inputting the Program .
72 access words in EM bank 1 and not the DM area. In this case, the second oper- and in the MOV(21) instruction transfers #1234 to a word in the EM bank.
73 SECTION 4 W riting and Inputting the Pr ogram This section explains the basic steps and concepts involved in writing a basic ladder diagram program, inputting the program into memory , and executing it. It introduces the instructions that are used to build the basic structure of the ladder diagram and control its execution.
74 4-1 Basic Procedure There are several basic steps involved in writing a program. Sheets that can be copied to aid in programming are provided in Appendix F Word Assignment Re- cording Sheets and Appendix G Program Coding Sheet .
75 4-3 Program Capacity The maximum user program size varies with the amount of UM allocated to ex- pansion DM and the I/O Comment Area. Approximately 10.1 KW are available fo r the ladder program when 3 KW are allocated to expansion DM and 2 KW are allocated t o I/O comments as shown below .
76 4-4-1 Basic T erms Each condition in a ladder diagram is either ON or OFF depending on the status of the operand bit that has been assigned to it. A normally open condition is ON if the operand bit is ON; OFF if the operand bit is OFF . A normally closed condition is ON if the operand bit is OFF; OFF if the operand bit is ON.
77 Program Memory addresses start at 00000 and run until the capacity of Program Memory has been exhausted. The first word at each address defines the instruc- tion.
78 LOAD and LOAD NOT The first condition that starts any logic block within a ladder diagram corre- sponds to a LOAD or LOAD NOT instruction. Each of these instruction requires one line of mnemonic code.
79 OR and OR NOT When two or more conditions lie on separate instruction lines which run in paral- lel and then join together , the first condition corresponds to a LOAD or LOAD NO T instruction; the other conditions correspond to OR or OR NOT instructions.
80 4-4-4 OUTPUT and OUTPUT NOT The simplest way to output the results of combining execution conditions is to output it directly with the OUTPUT and OUTPUT NOT . These instructions are used to control the status of the designated operand bit according to the execu- tion condition.
81 Now you have all of the instructions required to write simple input-output pro- grams. Before we finish with ladder diagram basic and go onto inputting the pro- gram into the PC, let ’ s look at logic block instruction (AND LOAD and OR LOAD), which are sometimes necessary even with simple diagrams.
82 Analyzing the above ladder diagram in terms of mnemonic instructions, the condition for IR 00000 is a LOAD instruction and the condition below it is an OR instruction between the status of IR 00000 and that of IR 00001. The condition at IR 00002 is another LOAD instruction and the condition below is an OR NOT instruction, i.
83 The following diagram requires AND LOAD to be converted to mnemonic code because three pairs of parallel conditions lie in series. The two options for coding the programs are also shown.
84 Both o f the coding methods described above can also be used when using AND LOAD and OR LOAD, as long as the number of blocks being combined does no t exceed eight. The following diagram contains only two logic blocks as shown. It is not neces- sary to further separate block b components, because it can be coded directly using only AND and OR.
85 Complicated Diagrams When determining what logic block instructions will be required to code a dia- gram, i t i s sometimes necessary to break the diagram into large blocks and then continue breaking the large blocks down until logic blocks that can be coded without logic block instructions have been formed.
86 Th e following diagram requires an OR LOAD followed by an AND LOAD to code th e top of the three blocks, and then two more OR LOADs to complete the mne- monic code.
87 Again, this diagram can be redrawn as follows to simplify program structure and coding and to save memory space. 00006 00007 LR 0000 00005 00001 00002 00003 00004 00000 Address Instruction Operands.
88 4-4-7 Coding Multiple Right-hand Instructions If there is more than one right-hand instruction executed with the same execu- tion condition, they are coded consecutively following the last condition on the instruction line. In the following example, the last instruction line contains one more condition that corresponds to an AND with IR 00004.
89 Y ellow: Operation Keys Th e yellow keys are used for writing and correcting programs. Detailed explana- tions of their functions are given later in this section. Except for the SHIFT key on the upper right, the gray keys are used to input instructions and designate data area prefixes when inputting or changing a pro- gram.
90 The gray keys other than the SHIFT key have either the mnemonic name of the instruction or the abbreviation of the data area written on them. The functions of these keys are described below . Pressed before the function code when inputting an instruction via its function code.
! ! 91 4-5-2 PC Modes T he Programming Console is equipped with a switch to control the PC mode. T o select one of the three operating modes — RUN, MONITOR, or PROGRAM — use the mode switch. The mode that you select will determine PC operation as well as the procedures that are possible from the Programming Console.
92 4. Confirm that the CPU Unit ’ s POWER LED is lit and the following display ap- pears on the Programming Console screen. (If the PC mode is not dis- played, turn OFF and restart the power supply . If the ALM/ERR LED is lit or flashing o r a n error message is displayed, clear the error that has occurred.
93 4-6-3 Clearing Memory Using the Memory Clear operation it is possible to clear all or part of the UM area (RAM or EEPROM), and the IR, HR, AR, DM, EM and TC areas. Unless other- wise specified, the clear operation will clear all of the above memory areas.
94 The following procedure is used to clear memory completely . Continue pressing the CLR key once for each error message until “ 00000 ” appears on the display All clear MEMORY ERR I/O VER ERR 00.
95 T o leave the TC area uncleared and retain Program Memory addresses 00000 through 00122, input as follows: 00000 00000 00000 00000MEMORY CLR? HR CNT DM EM~ 00000MEMORY CLR? HR DM EM~ 00123MEMORY CL.
96 Memory Clear The memory clear operation clears all memory areas except the I/O comments and UM Allocation information. The Programming Console will display the following screens: 00000 00000 00000 .

104 4-7 Inputting, Modifying, and Checking the Program Once a program is written in mnemonic code, it can be input directly into the PC from a Programming Console.
105 If the following mnemonic code has already been input into Program Memory , the key inputs below would produce the displays shown. 00000 00200 00200READ OFF LD 00000 00201READ ON AND 00001 00202RE.
! 106 The SV (set value) for a timer or counter is generally entered as a constant, although inputting the address of a word that holds the SV is also possible. When inputting an SV as a constant, CONT/# is not required; just input the numeric value and press WRITE.
107 Example The following program can be entered using the key inputs shown below . Dis- plays will appear as indicated. 00000 00200 00200 LD 00002 00201READ NOP (00) 00201 TIM 000 00201 TIM DATA #000.
108 Error Messages The following error messages may appear when inputting a program. Correct th e error as indicated and continue with the input operation. The asterisks in the displays shown below will be replaced with numeric data, normally an address, in the actual display .
109 Many o f the following errors are for instructions that have not yet been described yet. Refer to 4-8 Controlling Bit Status or to Section 5 Instruction Set for details on these. T ype Message Meaning and appropriate response T ype A ????? The program has been lost.

11 5 4-7-7 Branching Instruction Lines When a n instruction line branches into two or more lines, it is sometimes neces- sary to use either interlocks or TR bits to maintain the execution condition that existed at a branching point.
11 6 Th e previous diagram B can be written as shown below to ensure correct execu- tion. I n mnemonic code, the execution condition is stored at the branching point using the TR bit as the operand of the OUTPUT instruction.
11 7 When drawing a ladder diagram, be careful not to use TR bits unless necessary . Often the number of instructions required for a program can be reduced and ease of understanding a program increased by redrawing a diagram that would otherwise required TR bits.
11 8 When an INTERLOCK instruction is placed before a section of a ladder pro- gram, the execution condition for the INTERLOCK instruction will control the execution o f all instruction up to the next INTERLOCK CLEAR instruction.
11 9 If IR 00000 in the above diagram is OFF (i.e., if the execution condition for the first INTERLOCK instruction is OFF), instructions 1 through 4 would be executed with OFF execution conditions and execution would move to the instruction following the INTERLOCK CLEAR instruction.
120 The other type of jump is created with a jump number of 00. As many jumps as desired can be created using jump number 00 and JUMP instructions using 00 can be used consecutively without a JUMP END using 00 between them. It is even possible for all JUMP 00 instructions to move program execution to the same JUMP END 00, i.
121 4-8-1 DIFFERENTIA TE UP and DIFFERENTIA TE DOWN DIFFERENTIA TE UP and DIFFERENTIA TE DOWN instructions are used to turn the operand bit ON for one cycle at a time.
122 T o create a self-maintaining bit, the operand bit of an OUTPUT instruction is used a s a condition for the same OUTPUT instruction in an OR setup so that the operand bit of the OUTPUT instruction will remain ON or OFF until changes occur in other bits.
123 Work bits can be used to simplify programming when a certain combination of conditions i s repeatedly used in combination with other conditions. In the follow- ing example, IR 00000, IR 00001, IR 00002, and IR 00003 are combined in a logic block that stores the resulting execution condition as the status of IR 24600.
124 This action is easily programmed by using IR 22500 as a work bit as the operand of the DIFFERENTIA TE UP instruction (DIFU(13)). When IR 00000 turns ON, IR 22500 will be turned ON for one cycle and then be turned OFF the next cycle by DIFU(13).
125 Except for instructions for which conditions are not allowed (e.g., INTERLOCK CLEAR and JUMP END, see below), every instruction line must also have at least one condition on it to determine the execution condition for the instruction at the right.
126 4-1 1 Program Execution When program execution is started, the CPU Unit cycles the program from top to bottom, checking all conditions and executing all instructions accordingly as it moves down the bus bar .
127 4-12-2 Special I/O Unit Error Processing Program Us e a program like the one shown below to restart a Special I/O Unit in which an error has occurred.
128 5. Perform the Expansion Instruction Function Code Assignment operation to assign a function code to XDMR( –– ). 6. Input the program. The following program changes the Special I/O Unit Area settings for Unit 2, restarts the Unit, and disables calculations using data from Unit 2 while the Unit is initializing.
129 4-12-5 Reducing the Cycle Time When a Special I/O Unit is mounted in a C200HX/HG/HE PC, END refreshing is performed automatically each cycle without making any special settings. When several Special I/O Units are being used, the cycle time might become too long because of the time required for this automatic I/O refreshing.
130 The following program example is relevant for Special I/O Units mounted to the CP U Rack or Expansion I/O Racks only , because END refreshing is always per- formed o n Special I/O Units mounted to Slave Racks regardless of the PC Setup settings.
131 Refer to the Analog T imer Unit ’ s Operation Manual for details on switching between internal and external timer SV settings, connecting a variable resistor , and switch settings.
132 4-13-3 Example Program The following table shows the word allocations for the Units in this example. Item Word IR word allocated to the Analog T imer Unit IR 002 IR word allocated to the Input Uni.
133 The following diagram shows the switch settings and wiring connections required to achieve the Unit configuration shown above. The settings on these two variable resistor controls are valid because timers 0 and 1 are set for internal SV settings. Use the screwdriver included with the Unit to set the variable resistor .
134 The following diagram shows the example ladder program. 1, 2, 3... 1. Output IR 00500 will go ON about 0.6 s (T0) after input IR 00002 goes ON. 2. Output IR 00501 will go ON about 3 s (T1) after input IR 00003 goes ON.
135 SECTION 5 Instruction Set The C200HX/HG/HE PCs have large programming instruction sets that allow for easy programming of complicated control processes. This section explains instructions individually and provides the ladder diagram symbol, data areas, and flags used with each.

138 5-1 Notation In the remainder of this manual, all instructions will be referred to by their mne- monics. For example, the Output instruction will be called OUT ; the AND Load instruction, AND LD. If you ’ re not sure of the instruction a mnemonic is used for , refer to Appendix B Programming Instructions .
! 139 Caution Th e IR and SR areas are considered as separate data areas. If an operand has access to one area, it doesn ’ t necessarily mean that the same operand will have access to the other area. The border between the IR and SR areas can, howev- er , be crossed for a single operand, i.
140 5-4 Differentiated Instructions Most instructions are provided in both differentiated and non-differentiated forms. Differentiated instructions are distinguished by an @ in front of the instruction mnemonic. A non-differentiated instruction is executed each time it is cycled as long as its execution condition is ON.
141 5-5 Expansion Instructions The C200HX/HG/HE PCs have more instructions that require function codes (121) than function codes (100), so some instructions do not have fixed function codes. These instructions, called expansion instructions, are listed in the follow- ing table.

149 5-8 Ladder Diagram Instructions Ladder Diagram instructions include Ladder instructions and Logic Block instructions and correspond to the conditions on the ladder diagram.
150 5-8-2 AND LOAD and OR LOAD Ladder Symbol AND LOAD – AND LD 00002 00003 00000 00001 Ladder Symbol OR LOAD – OR LD 00000 00001 00002 00003 Description When instructions are combined into blocks that cannot be logically combined using only OR and AND operations, AND LD and OR LD are used.
151 OUT turns ON the designated bit for an ON execution condition, and turns OFF th e designated bit for an OFF execution condition. With a TR bit, OUT appears at a branching point rather than at the end of an instruction line. Refer to 4-7-7 Branching Instruction Lines for details.
152 Precautions DIFU(13) and DIFD(14) operation can be uncertain when the instructions are programmed between IL and ILC, between JMP and JME, or in subroutines. Re- fer to 5-10 INTERLOCK and INTERLOCK CLEAR – IL(02) and ILC(03) , 5-1 1 JUMP and JUMP END – JMP(04) and JME(05) , and 5-23 Subroutines and Inter- rupt Control for details.
153 5-9-3 SET and RESET – SET and RSET B : Bit IR, SR, AR, HR, LR Ladder Symbols Operand Data Areas SET B B : Bit IR, SR, AR, HR, LR RSET B Description SE T turns the operand bit ON when the execution condition is ON, and does not affect the status of the operand bit when the execution condition is OFF .
154 5-9-4 KEEP – KEEP(1 1) B : Bit IR, AR, HR, LR Ladder Symbol Operand Data Areas S R KEEP(1 1) B Limitations Any output bit can generally be used in only one instruction that controls its sta- tus. Refer to 3-3 IR Area for details. Description KEEP(1 1) is used to maintain the status of the designated bit based on two execution conditions.
155 th e input device) can cause the designated bit of KEEP(1 1) to be reset. This situ- ation is shown below . A Input Unit A NEVER S R KEEP(1 1) B Bits used in KEEP are not reset in interlocks. Refer to the 5-10 INTERLOCK – and INTERLOCK CLEAR IL(02) and ILC(03) for details.
156 Instruction T reatment OUT and OUT NOT Designated bit turned OFF . SET and RSET Bit status maintained. TIM and TIMH(15) Reset. TTIM(87) PV maintained. CNT , CNTR(12) PV maintained. KEEP(1 1) Bit status maintained. DIFU(13) and DIFD(14) Not executed (see the following DIFU(13) and DIFD(14) in Interlocks ).
157 Example The following diagram shows IL(02) being used twice with one ILC(03). Address Instruction Operands 00000 LD 00000 00001 IL(02) 00002 LD 00001 00003 TIM 51 1 # 0015 00004 LD 00002 00005 IL(.
158 If the jump number for JMP(04) is 00, the CPU Unit will look for the next JME(05) with a jump number of 00. T o do so, it must search through the program, causing a longer cycle time (when the execution condition is OFF) than for other jumps.
159 Any one TC number cannot be defined twice, i.e., once it has been used as the definer i n any of the timer or counter instructions, it cannot be used again. Once defined, TC numbers can be used as many times as required as operands in instructions other than timer and counter instructions.
160 If the execution condition remains ON long enough for TIM to time down to zero, the Completion Flag for the TC number used will turn ON and will remain ON until TIM is reset (i.
161 ON. When the SV in 005 has expired, 00201 is turned OFF . This bit will also be turned OFF when TIM 001 is reset, regardless of whether or not SV has expired.
162 002; 00000 in an inverse condition is necessary to reset TIM 002 when 00000 goes ON and 00500 is necessary to activate TIM 002 (when 00000 is OFF).
163 The following one-shot timer may be used to save memory . 00000 TIM 001 00100 00100 001.5 s TIM 001 #0015 Address Instruction Operands 00000 LD 00000 00001 OR 00100 00002 TIM 001 # 0015 00003 AND .
164 5-14-2 HIGH-SPEED TIMER – TIMH(15) N : TC number # (000 through 51 1, although 000 through 015 preferred) Ladder Symbol Definer V alues SV : Set value (word, BCD) IR, AR, DM, HR, LR, # Operand Data Areas TIMH(15) N SV Limitations SV is between 00.
165 5-14-3 T OT ALIZING TIMER – TTIM(87) SV : Set value (word, BCD) IR, AR, DM, HR, LR RB : Reset bit IR, SR, AR, HR, LR Ladder Symbol Operand Data Areas TTIM(87) N SV RB N : TC number # (000 through 51 1) Definer V alues Limitations SV is between 0000 and 9999 (000.
166 Example Th e following figure illustrates the relationship between the execution conditions for a totalizing timer with a set value of 2 s, its PV , and the Completion Flag.
167 Changes in execution conditions, the Completion Flag, and the PV are illus- trated below . PV line height is meant only to indicate changes in the PV .
168 Th e previously-shown CNT can be modified to restart from SV each time power is turned ON to the PC. This is done by using the First Cycle Flag in the SR area (25315) to reset CNT as shown below .
169 tween when the Completion Flag for TIM 001 goes ON and TIM 001 is reset by its Completion Flag). TIM 001 is also reset by the Completion Flag for CNT 002 so that the extended timer would not start again until CNT 002 was reset by 00001, which serves as the reset for the entire extended timer .
170 Limitations Each TC number can be used as the definer in only one TIMER or COUNTER instruction. Description The CNTR(12) is a reversible, up/down circular counter , i.e., it is used to count between zero and SV according to changes in two execution conditions, those in the increment input (II) and those in the decrement input (DI).
171 5-15 Data Shifting Al l of the instructions described in this section are used to shift data, but in diffe r- ing amounts and directions. The first shift instruction, SFT(10), shifts an execu- tion condition into a shift register; the rest of the instructions shift data that is al- ready in memory .
172 The following example uses the 1-second clock pulse bit (25502) so that the execution condition produced by 00005 is shifted into a 3-word register between IR 010 and IR 012 every second.
173 The program is set up so that a rotary encoder (00000) controls execution of SFT(10) through a DIFU(13), the rotary encoder is set up to turn ON and OFF each time a product passes the first sensor .
174 Description SFTR(84) is used to create a single- or multiple-word shift register that can shift data to either the right or the left. T o create a single-word register , designate the same word for St and E. The control word provides the shift direction, the status to be put into the register , the shift pulse, and the reset input.
175 5-15-3 ARITHMETIC SHIFT LEFT – ASL(25) Wd : Shift word IR, SR, AR, DM, HR, LR Ladder Symbols Operand Data Areas ASL(25) Wd @ASL(25) Wd Description When the execution condition is OFF , ASL(25) is not executed.
176 5-15-5 ROT A TE LEFT – ROL(27) Wd : Rotate word IR, SR, AR, DM, HR, LR Ladder Symbols Operand Data Areas ROL(27) Wd @ROL(27) Wd Description When the execution condition is OFF , ROL(27) is not executed.
177 5-15-7 ONE DIGIT SHIFT LEFT – SLD(74) Ladder Symbols Operand Data Areas SLD(74) St E @SLD(74) St E St : Starting word IR, SR, AR, DM, HR, LR E : End word IR, SR, AR, DM, HR, LR Limitations St and E must be in the same data area, and St must be less than or equal to E.
178 Precautions If a power failure occurs during a shift operation across more than 50 words, the shift operation might not be completed. Set the range between E and St to a maximum of 50 words. Flags ER: The St and E words are in different areas, or St is less than E.
179 Description When the execution condition is OFF , ASFT(17) does nothing and the program moves to t h e n e x t instruction. When the execution condition is ON, ASFT(17) is used to create and control a reversible asynchronous word shift register be- tween S t and E.
180 5-16 Data Movement This section describes the instructions used for moving data between different addresses in data areas. These movements can be programmed to be within th e same data area or between different data areas. Data movement is essential fo r utilizing all of the data areas of the PC.
181 Precautions TC numbers cannot be designated as D to change the PV of the timer or counter . However , these can be easily changed using BSET(71). Flags ER: Indirectly addressed DM word is non-existent. (Content of DM word is not BCD, or the DM area boundary has been exceeded.
182 Example Th e following example shows how to use BSET(71) to change the PV of a timer depending on the status of IR 00003 and IR 00004. When IR 00003 is ON, TIM 010 will operate as a 50-second timer; when IR 00004 is ON, TIM 010 will oper- ate as a 30-second timer .
183 Flags ER: N is not BCD between 0000 and 2000. S and S+N or D and D+N are not in the same data area. Indirectly addressed DM word is non-existent. (Content of DM word is not BCD, or the DM area boundary has been exceeded.
184 When the execution condition is OFF , DIST(80) is not executed. When the execution condition is ON, DIST(80) operates a stack from DBs to DBs+C – 9000. DBs is the stack pointer , so S is copied to the word indicated by DBs and DBs is incremented by 1.
185 5-16-7 DA T A COLLECT – COLL(81) SBs : Source base word IR, SR, AR, DM, HR, TC, LR C : Of fset data (BCD) IR, SR, AR, DM, HR, TC, LR, # Ladder Symbols Operand Data Areas D : Destination word IR, SR, AR, DM, HR, TC, LR COLL(81) SBs C D @COLL(81) SBs C D Limitations C must be a BCD.
186 Example In the following example, the content of C (HR 00) is 9010, and COLL(81) is used to copy the oldest entries from a10-word stack (IR 001 to IR 010) to LR 20.
187 Example In the following example, the content of C (HR 00) is 8010, and COLL(81) is used to copy the most recent entries from a 10-word stack (IR 001 to IR 010) to LR 20.
188 Description When the execution condition is OFF , MOVB(82) is not executed. When the execution condition is ON, MOVB(82) copies the specified bit of S to the speci- fied bit in D. The bits in S and D are specified by Bi. The rightmost two digits of Bi designate the source bit; the leftmost two bits designate the destination bit.
189 Digit Designator The following show examples of the data movements for various values of Di. 0 1 2 3 0 1 2 3 0 1 2 3 0 1 2 3 S Di: 0031 Di: 0023 Di: 0030 Di: 0010 S S S 0 1 2 3 D 0 1 2 3 D 0 1 2 3 D 0 1 2 3 D Flags ER: At least one of the rightmost three digits of Di is not between 0 and 3.
190 Example In the following example, XFRB(62) is used to transfer 5 bits from IR 020 to LR 2 1 when IR 00001 is ON. The starting bit in IR 020 is 0, and the starting bit in LR 21 is 4, so IR 02000 to IR 02004 are copied to LR 2104 to LR 2108.
191 Example The following example copies the contents of the 300 words from DM 0000 through DM 0299 to EM 2000 through EM 2299 in the current EM bank. XFR2( –– ) #0300 DM 0000 #2000 00000 Address .
192 Example The following example copies the contents of the 300 words from DM 0000 through DM 0299 to EM 2000 through EM 2299 in the EM bank 01. (EM bank 00 isn ’ t used as the source because S isn ’ t a constant.
193 Example The following example shows the comparisons made and the results provided for MCMP(19). Here, the comparison is made during each cycle when 00000 is ON.
194 Flags ER: Indirectly addressed DM word is non-existent. (Content of DM word is not BCD, or the DM area boundary has been exceeded.) EQ : ON if Cp1 equals Cp2.
195 The branching structure of this diagram is important in order to ensure that 00200, 00201, and 00202 are controlled properly as the timer counts down. Be - cause all of the comparisons here use to the timer ’ s PV as reference, the other operand for each CMP(20) must be in 4-digit BCD.

197 The following example shows how to save the comparison result immediately . If th e content of HR 10, HR 09 is greater than that of 01 1, 010, then 00200 is turned ON; if the two contents are equal, 00201 is turned ON; if content of HR 10, HR 0 9 is less than that of 01 1, 010, then 00202 is turned ON.
198 Description When the execution condition is OFF , BCMP(68) is not executed. When the execution condition is ON, BCMP(68) compares CD to the ranges defined by a block consisting of of CB, CB+1, CB+2, ..., CB+31. Each range is defined by two words, the first one providing the lower limit and the second word providing the upper limit.
199 Example The following example shows the comparisons made and the results provided for BCMP(68). Here, the comparison is made during each cycle when 00000 is ON.
200 Example The following example shows the comparisons made and the results provided for TCMP(85). Here, the comparison is made during each cycle when 00000 is ON.
201 Precautions Placing other instructions between ZCP(88) and the operation which accesses the EQ, LE, and GR flags may change the status of these flags. Be sure to ac- cess them before the desired status is changed. Flags ER: Indirectly addressed DM word is non-existent.
202 Description When the execution condition is OFF , ZCPL( –– ) is not executed. When the execution condition is ON, ZCPL( –– ) compares the 8-digit value in CD, CD+1 to the range defined by lower limit LL+1,LL and upper limit UL+1,UL and outputs th e result to the GR, EQ, and LE flags in the SR area.

212 The following program converts three digits of data from LR 20 to bit positions and turns ON the corresponding bits in three consecutive words starting with HR 10.
213 16-bit to 4-bit Encoder DMPX(77) operates as a 16-bit to 4-bit encoder when the leftmost digit of C is 0. When the execution condition is OFF , DMPX(77) is not executed.
214 256-bit to 8-bit Encoder DMPX(77) operates as a 256-bit to 8-bit encoder when the leftmost digit of C is set to 1. When the execution condition is OFF , DMPX(77) is not executed.
215 When 00000 is ON, the following diagram encodes IR words 010 and 01 1 to t he first two digits of HR 20 and then encodes LR 10 and 1 1 to the last two digits of HR 20. Although the status of each source word bit is not shown, it is assumed that the bit with status 1 (ON) shown is the highest bit that is ON in the word.
216 Any or all of the digits in S may be converted in sequence from the designated first digit. The first digit, the number of digits to be converted, and the half of D to receive the first 7-segment display code (rightmost or leftmost 8 bits) are desig- nated in Di.
217 Example The following example shows the data to produce an 8. The lower case letters show which bits correspond to which segments of the 7-segment display . The table underneath shows the original data and converted code for all hexadeci- mal digits.

249 Precautions DVB(53) cannot be used to divide signed binary data. Use DBS( –– ) instead. Re- fer to 5-20-9 SIGNED BINAR Y DIVIDE – DBS( –– ) for details. Flags ER: Dr contains 0. Indirectly addressed DM word is non-existent. (Content of DM word is not BCD, or the DM area boundary has been exceeded.
250 ADBL( –– ) can also be used to add signed binary data. The overflow and under- flow flags (SR 25404 and SR 25405) indicate whether the result has exceeded th e lower or upper limits of the 32-bit signed binary data range. Refer to page 27 for details on signed binary data.
251 In the case below , 1,799,100,099 + ( – 282,751,929) = 1,516,348,100 (6B3C167D + EF258C47 = 5A61A2C4). Neither OF nor UF are turned ON. Au + 1 : LR 21 Au : LR 20 Ad + 1 : DM 001 1 Ad : DM 0010 6.

253 In the case below , 1,799,100,099 – ( – 282,751,929) = 2,081,851,958 (6B3C 167D – {EF25 8C47 – 1 0000 0000} = 7C16 8A36). Neither OF nor UF are turned ON.
254 Example In the following example, MBS( –– ) is used to multiply the signed binary contents of IR 001 with the signed binary contents of DM 0020 and output the result to LR 21 and LR 22.
255 Example In the following example, MBSL( –– ) is used to multiply the signed binary con- tents of IR 101 and IR 100 with the signed binary contents of DM 0021 and DM 0020 and output the result to LR 24 through LR 21.
256 Example In the following example, DBS( –– ) is used to divide the signed binary contents of IR 001 with the signed binary contents of DM 0020 and output the result to LR 21 and LR 22.
257 Example In the following example, DBSL( –– ) is used to divide the signed binary contents of IR 002 and IR 001 with the signed binary contents of DM 0021 and DM 0020 and output the result to LR 24 through LR 21.
! 258 If bit 15 of C is ON and more than one address contains the same maximum val- ue, the position of the lowest of the addresses will be output to D+1. Th e number of words within the range (N) is contained in the 3 rightmost digits of C, which must be BCD between 001 and 999.
! 259 2. For an address in another data area, the number of addresses from the be- ginning of the search is written to D+1. For example, if the address contain- ing the minimum value is IR 1 14 and the first word in the search range is IR 014, then #0100 is written in D+1.
260 For the first N – 1 cycles when the execution condition is ON, A VG ( –– ) writes the value of S t o D . E a c h t i m e t h a t A VG( –– ) is executed, the previous value of S is stored in words D+2 to D+N+1.
261 Example In the following example, the content of IR 040 is set to #0000 and then increm- ented by 1 each cycle. For the first two cycles, A VG( –– ) moves the content of IR 040 to DM 1002 and DM 1003. The contents of DM 1001 will also change (which can be used to confirm that the results of A VG ( –– ) has changed).
262 Description When the execution condition is OFF , SUM( –– ) is not executed. When the execution condition is ON, SUM( –– ) adds either the contents of words R 1 to R 1 +N – 1 or the bytes in words R 1 to R 1 +N/2 – 1 and outputs that value to the des- tination words (D and D+1).
263 Example In the following example, the BCD contents of the 10 words from DM 0000 to DM 0009 are added when IR 00001 is ON and the result is written to DM 0100 and DM 0101.

280 INT(89) is used to control the interrupt signals received from the Interrupt Input Unit, and also to control the scheduling of the scheduled interrupt. INT(89) pro- vides such functions as masking of interrupts (so that they are recorded but ig- nored) and clearing of interrupts.
281 started. The program must be designed to allow for this when required by the application. (See the section on data concurrence for further details.) Input Interrupts Input interrupts are executed when external inputs are received via an Interrupt Input Unit.
282 Note Disabling special I/O refreshing in the normal cycle to refresh special I/O in an interrupt subroutine is necessary only in the high-speed mode. Disabling normal cycle refreshing of special I/O during normal interrupt mode will be ignored and th e special I/O will be refreshed both in the normal cycle and in the interrupt sub- routine.
283 • Use the I/O REFRESH instruction in interrupt subroutines to refresh required I/ O from Special I/O Units and mask interrupts in the main program while read- ing/writing Special I/O Unit words.
! 284 The following diagram illustrates program execution flow for various execution conditions for two SBS(91). SBS(91) 000 SBS(91) 001 SBN(92) 000 RET(93) SBN(92) 001 RET(93) END(001) Main program S.
285 Al l subroutines must be programmed at the end of the main program. When one or more subroutines have been programmed, the main program will be executed up to the first SBN(92) before returning to address 00000 for the next cycle. Subroutines will not be executed unless called by SBS(91).
286 In the following example, the contents of DM 0010 through DM 0013 are copied to SR 290 through SR 293, the contents of DM 0020 through DM 0023 are co- pied to SR 294 through SR 297, and subroutine 010 is called and executed. When the subroutine is completed, the contents of SR 294 through SR 297 are copied back to DM 0020 to DM 0023.
287 Example The following examples shows the use of four MCRO(99) instructions that ac- cess the same subroutine. The program section on the left shows the same pro- gram without the use of MCRO(99).
288 Description INT(89) is used to control interrupts and performs one of 1 1 functions depending on the values of C and N. As shown in the following tables, six of the functions act on input interrupts, three act on the scheduled interrupt, and the other two mask or unmask all interrupts.
289 This function is used to write the current setting for the scheduled interrupt inter- val to word D. This function is used to mask or unmask all interrupt processing. Masked inputs are recorded, but ignored. The masked inputs will be serviced as soon as they are unmasked.
290 Th e scheduled interrupt is disabled at the start of operation (the scheduled inter- rupt interval is 0), so the time to the first interrupt and scheduled interrupt interval must b e set using INT(89) with N=004 and C=001/000.
291 5-24 Step Instructions Th e step instructions STEP(08) and SNXT(09) are used in conjunction to set up breakpoints between sections in a large program so that the sections can be executed as units and reset upon completion. A section of program will usually be defined to correspond to an actual process in the application.
292 Execution o f a step is completed either by execution of the next SNXT(09) or by turning OFF the control bit for the step (see example 3 below). When the step is completed, all of the IR and HR bits in the step are turned OFF . All timers in the step except TTIM( –– ) are reset to their SVs.
293 Flags 25407: Step Start Flag; turns ON for one cycle when STEP(08) is executed and can be used to reset counters in steps as shown below if necessary .
294 The following diagram demonstrates the flow of processing and the switches that are used for execution control. Process A Process B Process C Loading Part Installation Inspection/discharge SW1 SW2.
295 The program for this process, shown below , utilizes the most basic type of step programming: each step is completed by a unique SNXT(09) that starts the next step. Each step starts when the switch that indicates the previous step has been completed turns ON.
296 The following process requires that a product is processed in one of two ways, depending on its weight, before it is printed. The printing process is the same regardless of which of the first processes is used. V arious sensors are posi- tioned to signal when processes are to start and end.
297 The program for this process, shown below , starts with two SNXT(09) instruc- tions that start processes A and B. Because of the way 00001 (SW A1) and 00002 (SB B1) are programmed, only one of these will be executed to start either process A or process B.
298 The following process requires that two parts of a product pass simultaneously through two processes each before they are joined together in a fifth process.

301 F AL(06) produces a non-fatal error and F AL(07) produces a fatal error . When F AL(06) is executed with an ON execution condition, the ALARM/ERROR indi- cator o n the front of the CPU Unit will flash, but PC operation will continue.
302 5-25-3 TRACE MEMOR Y SAMPLING – TRSM(45) Data tracing can be used to facilitate debugging programs. T o set up and use data tracing it is necessary to have a host computer running SSS; no data tracing is possible from a Programming Console. Data tracing is described in detail in the SSS Operation Manual .
303 The sampled data is written to trace memory , jumping to the beginning of the memory area once the end has been reached and continuing up to the start marker . This might mean that previously recorded data (i.e., data from this sam- ple that falls before the start marker) is overwritten (this is especially true if the delay i s positive).
MSG ABCDEFGHIJKLMNOP 304 In handling indirectly addressed messages (i.e. DM), those with the lowest DM address values have higher priority . Clearing Messages T o clear a message, execute F AL(06) 00 or clear it via a Programming Console using the procedure in 4-6-5 Clearing Error Messages .
305 Description LMSG(47) is used to output a 32-character message to a Programming Con- sole. The message to be output must be in ASCII beginning in word S and end- in g in S+15, unless a shorter message is desired.
306 Example In the following example, TERM(48) is used to switch the Programming Console to TERMINAL mode when 00000 is ON. Be sure that pin 6 of the CPU Unit ’ s DIP switch is OFF .
307 It cannot be used for other I/O words, such as I/O Units on Slave Racks or Group-2 High-density I/O Units. St must be less than or equal to E. Description T o refresh I/O words allocated to CPU or Expansion I/O Racks (IR 000 to IR 029 or IR 300 to IR 309), simply specify the first (St) and last (E) I/O words to be re- freshed.
308 Refer to 6-1 Cycle Time for a table showing I/O refresh times for Group-2 High-density I/O Units. Flags ER : St or E is not BCD between #0000 and #000F .
309 The function of bits in C are shown in the following diagram and explained in more detail below . 15 14 13 12 1 1 00 Number of items in range (N, BCD) 001 to 999 words or bytes First byte (when bit 13 is ON) 1 (ON): Rightmost 0 (OFF): Leftmost Calculation units 1 (ON): Bytes 0 (OFF): Words C: Not used.
310 Example When IR 00000 is ON in the following example, the frame checksum (0008) is calculated for the 8 words from DM 0000 to DM 0007 and the ASCII equivalent (30 30 30 38) is written to DM 001 1 and DM 0010.
31 1 When the execution condition is OFF , FPD( –– ) is not executed. When the execution condition is ON, FPD( –– ) monitors the time until the logic diagnostics condition goes ON, turning ON the diagnostic output. If this time exceeds T , the following will occur: 1, 2, 3.
312 D+1 contains the bit address code of the input condition, as shown below . The word addresses, bit numbers, and TC numbers are in binary . Data D+1 bit status area 15 14 13 12 11 10 09 08 07 06 05.
313 Example In the following example, the FPD( –– ) is set to display the bit address and mes- sage ( “ ABC ” ) when a monitoring time of 123.4 s is exceeded.

315 Example In the following example, the 10 word range from DM 0010 to DM 0019 is searched for addresses that contain the same data as DM 0000 (#FFFF). Since DM 0012 contains the same data, the EQ Flag (SR 25506) is turned ON and #0012 is written to DM 0001.
316 Example In the following example, the 100 word range from DM 7000 through DM 7099 is copied to DM 0010 through DM 0109 when IR 00001 is ON. @XDMR( –– ) #7000 #0100 00001 DM 0010 Address Instru.
317 Note Input 000 for the second and third operands when using replacement instruc- tions. Flags ER: C is not one of the allowed values. Example In the following example, IEMS( –– ) changes the destination for DM to EM bank 1 and uses indirect addressing to move #1234 into EM 0001 in EM bank 1.
318 5-26 Network Instructions The network instructions are used for communicating with other PCs, BASIC Units, or host computers linked through the SYSMAC NET Link System, SYS- MAC LINK System, Ethernet System, or Controller Link System.
319 SYSMAC NET Link Systems T he destination port number is always set to 0. Set the destination node number to 0 to send the data to all nodes. Set the network number to 0 to send data to a node on the same Subsystem (i.e., network). Refer to the SYSMAC NET Link System Manual for details.
320 SEND(90) transmits “ n ” words beginning with S (the beginning source word for data transmission at the source node) to the “ n ” words beginning with D (the be- ginning destination word for data reception at destination node N).
321 Indirect Destination Beginning Word Designations D is used to specify the destination beginning word as follows when indirect specification is designated: 12 to 15 08 to 1 1 04 to 07 00 to 03 D Area type 0 Word no. (5th digit) D+1 Word no. (4th digit) Word no.
322 C-series PCs Designation Area Area code Word number IR area 00 0 to 51 1 LR area 06 0 to 63 HR area 07 0 to 99 SR area 08 0 to 27 T imer area (PV) 03 0 to 51 1 DM area 05 0 to 6655 CV -series PCs .
323 Examples This example is for a SYSMAC NET Link System. When 00000 is ON, the follow- in g program transfers the content of IR 001 through IR 005 to LR 20 through LR 24 on node 10.
324 Control Data Ethernet Systems Refer to the PC Card Unit Operation Manual for details. Word Bits 00 to 07 Bits 08 to 15 C Number of words (0 to 1000 in 4-digit hexadecimal, i.e., 0000 hex to 03E8 hex) C+1 Response time limit (0.1 and 25.4 seconds in 0.
325 RECV(98) receives “ m ” words beginning with S (the beginning word for data transmission a t the destination node, M) to the words from D (the beginning word for data reception at the source node) onwards.
326 2. With the message service, there is no guarantee that a message to a des- tination node will reach its destination. It is always possible that the mes- sage may be lost in transit due to noise or some other condition.
327 5-26-3 About Network Communications SEND(90) and RECV(98) are based on command/response processing. That is, the transmission is not complete until the sending node receives and ac- knowledges a response from the destination node.

362 The first three operations immediately after power application are performed only once each time the PC is turned on. The rest of the operations are per- formed in cyclic fashion. The cycle time is the time that is required for the CPU Unit to complete one of these cycles.

! 364 Within the PC, the watchdog timer measures the cycle time and compares it to a set value. If the cycle time exceeds the set value of the watchdog timer , a F ALS 9F error is generated and the CPU Unit stops. WDT(94) can be used to extend the set value for the watchdog timer .
365 6-2-1 PC with I/O Units Only Here, we ’ ll compute the cycle time for a simple PC. The CPU Unit controls only I/O Units, eight on the CPU Rack and five on a 5-slot Expansion I/O Rack. The PC configuration for this would be as shown below . It is assumed that the pro- gram contains 5,000 instructions requiring an average of 0.
366 It is assumed that the program contains 5,000 instructions requiring an average of 0.156 µ s each to execute, and that nothing is connected to the RS-232C port and no SYSMAC NET/SYSMAC LINK Unit is mounted.

376 6-4 I/O Response T ime The I/O response time is the time it takes for the PC to output a control signal after i t has received an input signal. The time it takes to respond depends on the cycle time and when the CPU Unit receives the input signal relative to the input refresh period.
377 The PC takes longest to respond when it receives the input signal just after the I/ O refresh phase of the cycle. In this case the CPU Unit does not recognize the input signal until the end of the next cycle.
! 378 In looking at the following timing charts, it is important to remember the se- quence i n which processing occurs during the PC scan, particular that inputs will not produce programmed actions until the program has been executed.
379 The maximum response time occurs when the input just misses the program execution portion of the scan, meaning that processing must wait for the next transmission and then the next (i.
380 6-4-3 Host Link Systems The following diagram illustrates the processing that takes place when an input on one PC is transferred through the Host Link System to turn ON an output on another PC. Refer to Host Link System documentation for further details.
381 In looking at the following timing charts, it is important to remember the se- quence processing occurs during the PC scan, particular that inputs will not pro- duce programmed-actions until the program has been execution.
382 Output ON delay: 15 ms Cycle time for PC of Unit 0: 20 ms Cycle time for PC of Unit 7: 50 ms Minimum transmission time: 2.8 ms+10 ms=12.8 ms The following diagram illustrates the data flow that will produce the maximum response time.

389 SECTION 7 Pr ogram Monitoring and Execution This section provides the procedures for monitoring and controlling the PC through a Programming Console. Refer to the SYSMAC Support Softwar e Operation Manual for SSS procedures if you are using a computer running SSS.
390 7-1 Monitoring Operation and Modifying Data Th e simplest form of operation monitoring is to display the address whose oper- and bit status is to be monitored using the Program Read or one of the search operations. As long as the operation is performed in RUN or MONITOR mode, the status of any bit displayed will be indicated.

417 SECTION 8 Serial Communications This sec tion provides an overview of the serial communications (Host Link, RS-232C, one-to-one links, NT links, and proto- col macros) that operate through the RS-232C, RS-422/485, and Peripheral Ports. 8-1 Introduction 418 .
418 8-1 Introduction The RS-232C port and peripheral port built into the C200HX/HG/HE PC ’ s CPU Unit support the following communications functions: • Communications with Programming Devices (e.g., Programming Console or SSS.) • Host Link communications with personal computers and other external de- vices.
419 8-2 Host Link Communications 8-2-1 Host Link Command Summary Host Link communications are used to transfer data between the PC and a host computer (a personal computer or PT). It is possible to monitor the PC ’ s operat- ing status and the contents of PC data areas from the host computer using Host Link commands.
420 The connections between the C200HX/HG/HE and a personal computer are il- lustrated below as an example. 1 2 3 4 5 6 FG SD RD RS CS – – – SG 7 8 9 1 2 3 4 5 6 7 8 9 SD RD RS CS DSR SG – 9 DTR C200HX/HG/HE Personal computer Signal Pin No. Signal Pin No.
421 Custom Port Settings Standard settings or custom settings can be used for the RS-232C and peripher- al ports. The custom settings are used when the following bits are set to 1. RS-232C port: Bits 00 through 03 of DM 6645 (0: standard; 1: custom). Peripheral port: Bits 00 through 03 of DM 6650 (0: standard; 1: custom).
422 Note If pin 5 of the CPU Unit ’ s DIP switch is ON, the standard communications set- tings will be used regardless of the settings in the PC Setup.
423 Response Frame Format Th e response from the PC is returned in the format shown below . Prepare a pro- gram so that the response data can be interpreted and processed. @ x 10 1 x 10 0 x 16 1 x 16 0 FCS ↵ Node no. Header code End code T ext T erminator Th e header code and text depend on the Host Link command that was received.
424 Communications Sequence Th e right to send a frame is called the “ transmission right. ” The Unit that has the transmission right is the one that can send a frame at any given time. The trans- mission right is traded back and forth between the host computer and the PC each time a frame is transmitted.
425 8-2-3 Example Programs Command T ransmission T he following type of program must be prepared in the host computer to receive the data. This program allows the computer to read and display the data re- ceived from the PC while a host link read command is being executed to read data from the PC.
426 Th e default values are assumed for all of the PC Setup (i.e., the RS-232C port is used in Host Link mode, the node number is 00, and the standard communica- tions parameters are used.
427 Specify whether or not a start code is to be set at the beginning of the data, and whether or not an end code is to be set at the end. Instead of setting the end code, it is possible to specify the number of bytes to be received before the re- ception operation is completed.
428 2. Us e the TXD( –– ) instruction to transmit the data. (Bits 08 to 1 1 are valid only when bits 12 to 15 are set to 0.) (@)TXD S C N S: Address of first word of data to be transmitted C: Cont.
429 3. When RXD( –– ) is executed, the received data is transferred to the specified words (without the start and end codes) and the Reception Completed Flag is turned OFF . The start and end of reception are as follows: Start: Continuous reception status if the start code is not enabled.
430 8-4 One-to-one PC Links If two PCs are linked one-to-one by connecting them together through their RS-232C ports, they can share common LR areas. When two PCs are linked one-to-one, one of them will serve as the master and the other as the slave.
431 PC Setup T o use a 1:1 link, the only settings necessary are the communications mode and the link words. Set the communications mode for one of the PCs to one-to-one link master and th e other PC to one-to-one link slave, and then set the link words in the PC desig- nated as the master .
432 8-5 NT Links A one-to-one NT link that uses NT link commands can be established by con- necting the RS-232C port of the PC to the RS-232C port of a Programmable T er - minal (PT). A one-to-N NT link that uses NT link commands can be established by connect- ing the PC and Programmable T erminal (PT) with RS-422/485 cable.
433 Restrictions on Use I f the C200H-OV001 V oice Unit is being used, the 1:N mode cannot be used with th e RS-232 port. In that case, either use the NT Link in 1:1 mode or use the 1:N mode with the port on the communications board.
434 An RS-422/485 connection allows 2 or more devices to be connected (one-to-N connection) with a maximum cable length of 500 m. The RS-422/485 connection is also useful for distant one-to-one connections. (RS-232C) Port B (RS-422/485) Port A RS-232C 500 m max.
435 General Device/Computer Connections (RS/CS Flow , Cross Connection) C200HX/HG/HE Host computer Modem Connection (Straight Connection) C200HX/HG/HE Modem Note Ground the FG terminals on the PC and at the other device to 100 Ω or less.
436 8-6-2 Communications Board Settings The following parameters must be set in advance in order to use the Protocol Macro function through a Communications Board. Communications Mode Set the communications mode to Protocol Macro mode. Port B: Set bits 12 through 15 of DM 6550 to 6.
437 Parameter Setting Baud rate Baud rate 00 1,200 bps 01 2,400 bps 02 4,800 bps 03 9,600 bps 04 19,200 bps 8-6-3 Communications Procedure Th e Protocol Macro ’ s communications sequences must be created with the Pro- tocol Support Software and transferred to the Communications Board in ad- vance.
438 The transmission message and reception message have the following struc- ture. Header Address Length Data Error check T erminator Item Function Header Set the data that indicates the beginning of the message. Address Set the node number or other identifier that indicates the destination for the message.
439 Read Word (R) Word data can be read by setting the desired attributes for the “ address ” or “ data ” in the transmission and reception messages. When the attribute is set, the address or data is read from the specified word. There are three ways to specify the word: 1, 2, 3.
440 Example: R(2N+6) Specifies the sixth word following the PMCR( –– ) instruction ’ s second operand fo r the “ address ” or “ data ” and adds two words to the specification each time that the step is repeated.
441 Se t the wild card ( ) in the reception message so that all data will be received. In the next process, set “ End ” in both the transmission step and the reception step. In error processing, set “ Abort ” in both the transmission step and the reception step.
443 SECTION 9 T roubleshooting The C200HX/HG/HE provides self-diagnostic functions to identify many types of abnormal system conditions. These func- tions minimize downtime and enable quick, smooth error correction. This section provides information on hardware and software errors that occur during PC operation.
! 444 9-1 Alarm Indicators Th e ALM/ERR indicator on the front of the CPU Unit provides visual indication of an abnormality in the PC. When the indicator is ON (ERROR), a fatal error (i.e., ones that will stop PC operation) has occurred; when the indicator is flashing (ALARM), a nonfatal error has occurred.
445 9-4 Error Messages There are basically three types of errors for which messages are displayed: ini- tialization errors, non-fatal operating errors, and fatal operating errors. Most of these a r e a l s o i n d i c a t e d b y F AL number being transferred to the F AL area of the SR area.

539 Glossary address The location in memory where data is stored. For data areas, an address con- sists of a two-letter data area designation and a number that designates the word and/or bit location. For the UM area, an address designates the instruction location (UM area).
Glossary 540 bit designator An operand that is used to designate the bit or bits of a word to be used by an instruction. bit number A number that indicates the location of a bit within a word. Bit 00 is the rightmost (least-significant) bit; bit 15 is the leftmost (most-significant) bit.
Glossary 541 counter A dedicated group of digits or words in memory used to count the number of times a specific process has occurred, or a location in memory accessed through a T C bit and used to count the number of times the status of a bit or an execution condition has changed from OFF to ON.
Glossary 542 differentiated instruction An instruction that is executed only once each time its execution condition goes from OFF to ON. Non-dif ferentiated instructions are executed each cycle as long as the execution condition stays ON.
Glossary 543 extended counter A counter created in a program by using two or more count instructions in suc- cession. Such a counter is capable of counting higher than any of the standard counters provided by the individual instructions. extended timer A timer created in a program by using two or more timers in succession.
Glossary 544 increment Increasing a numeric value. indirect address An address whose contents indicates another address. The contents of the se- cond address will be used as the operand. Indirect addressing is possible in the DM area only . initialization error An error that occurs either in hardware or software during the PC System start- up, i.
Glossary 545 inverse condition A condition that produces an ON execution condition when the bit assigned to it is OFF , and an OFF execution condition when the bit assigned to it is ON. I/O capacity The number of inputs and outputs that a PC is able to handle.
Glossary 546 ladder diagram (program) A form of program arising out of relay-based control systems that uses circuit- type diagrams to represent the logic flow of programming instructions. The ap- pearance of the program is similar to a ladder , and thus the name.
Glossary 547 LR area A data area that is used in a PC Link System so that data can be transferred be- tween two or more PCs. If a PC Link System is not used, the LR area is available for use as work bits. main program All of a program except for the subroutines.
Glossary 548 normal condition A condition that produces an ON execution condition when the bit assigned to it is ON, and an OFF execution condition when the bit assigned to it is OFF .
Glossary 549 output device An external device that receives signals from the PC System. output point The point at which an output leaves the PC System. Output points correspond physically to terminals or connector pins. output signal A signal being sent to an external device.
Glossary 550 Programmable Controller A computerized device that can accept inputs from external devices and gener- ate outputs to external devices according to a program held in memory . Pro- grammable Controllers are used to automate control of external devices.
Glossary 551 Remote I/O System A system in which remote I/O points are controlled through a Master mounted to a CPU Rack or an Expansion I/O Rack connected to the CPU Rack. Remote I/O Unit Any of the Units in a Remote I/O System. Remote I/O Units include Masters, Slaves, Optical I/O Units, I/O Link Units, and Remote T erminals.
Glossary 552 Slave Short for Remote I/O Slave Unit. Slave Rack A Ra ck c onta ini ng a Remote I/O Slave Unit and controlled through a Remote I/O Master Unit. Slave Racks are generally located away from the CPU Rack. slot A position on a Rack (Backplane) to which a Unit can be mounted.
Glossary 553 terminal instruction An instruction placed on the right side of a ladder diagram that uses the final execution conditions of an instruction line. terminator Th e code comprising an asterisk and a carriage return (* CR) which indicates the end of a block of data, whether it is a single-frame or multi-frame block.
Glossary 554 word setting made on the Unit is added to 32 times the word multiplier to arrive at the actual word to be allocated. work bit A bit in a work word. work word A word that can be used for data calculation or other manipulation in program- ming, i.
