1 SECTION 1 General Thi s section provides fundamental information about the functions and features of the PT s, types of connection, communica- tion methods, etc. This information will enable you to understand the applications of the PT s. 1-1 Role and Operation of the NT31/NT31C 2 .
1-1 Section Role and Operation of the NT31/NT31C 2 1-1 Role and Operation of the NT31/NT31C Th e NT31/NT31C is a sophisticated display unit (programmable terminal) which automatically displays information and can also be used for operations when necessary .
1-1 Section Role and Operation of the NT31/NT31C 3 1-1-2 Operations of the NT31/NT31C Th e information to be displayed (screen data) can be created on a computer us - ing the Support T ool and stored in the NT31/NT31C. The screen data can be displayed on the NT31/NT31C in response to instructions from the host or touch switch operation.
1-2 Section Functions of the NT31/NT31C 4 1-2 Functions of the NT31/NT31C The NT31/NT31C has the following features. 1-2-1 Features Downsized Body • Slim body (50 mm or less in the panel*). • Th e communication cable connectors are housed in the unit so that they do not protrude from the unit.
1-2 Section Functions of the NT31/NT31C 5 Screen data can be checked simply by operations at the NT31/NT31C system menu, without connecting up to the Support T ool. Th e data capacity of 1 MB is twice that of the NT30/NT30C, enabling storage of a larger quantity of screen data.
1-2 Section Functions of the NT31/NT31C 6 1-2-3 Additional Functions of the V2 V ersions The V2 versions of NT31/NT31C are supplemented and enhanced by the fol- lowing functions. The V2 versions are compatible with the high-speed 1:N NT Link as well as the earlier standard 1:N NT Link.

1-2 Section Functions of the NT31/NT31C 9 1-2-5 Principal Functions of NT31/NT31C The following are the principal functions of the NT31/NT31C. Functions relating to data display Character display Characters of various sizes can be displayed. Char acters can be flashed and displayed in reverse video.
Section 10 Functions relating to the system System menu System settings and maintenance can be performed by selecting from system menus displayed on the screen. Creation of screen data Screen data created using the Support T ool at a personal computer can be transferred and stored in the built-in screen data mem ory .
Section 11 1-2-6 Displays Th e NT31/NT31C can display various kinds of elements such as characters, nu- mer ic values, graphs, lamps, and touch switches, on a screen. The screen data displayed by the NT31/NT31C are created by using the Support T ool at a per- sonal computer .
Section 12 Library data are combinations of fixed display graphics registered as a single graphic. They are registered in advance and as many as required can be dis- played at any position on the screen. Since it is generated by combining graphics, library data has a small data size.
Section 13 T ouch sw itches can be made to light or flash in accordance with the status of a host bit in the same way as lamps. The following 8 types of display graphic can be used for touch switches:.
Section 14 Numeric values can be input by incrementing or decrementing each digit with the corresponding touch switch (+, –). The input numeric values can also be stored in a numeral memory table and notified to the host. Thumbwheel switch inputs can be enabled and disabled from the host when an interlock bit has been allocated.
Section 15 The alarm list/history function displays messages in list form, or graphics (image/library data), in accordance with changes in bit memory table statuses. For the alarm list, a series of bit memory tables are monitored, and messages (contents of character string memory tables) set for bit memory tables that come ON are displayed.
