Page 21: Principal Functions Of Nt31/Nt31C
Functions of the NT31/NT31C 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. Characters can be flashed and displayed in reverse video.
Page 22: System Menu
Functions relating to data input Input by touch switches Data can be input by simply touching touch switches displayed on the screen. The possible functions of touch switches include sending data to the host and changing the screen display. Inputs can be enabled and disabled from the host when interlock bits have been allocated. Pop-up window function A window overlaying the currently displayed screen can be alternately opened and closed by pressing a touch switch.
Page 23: Displays
1-2-6 Displays The NT31/NT31C can display various kinds of elements such as characters, nu- meric values, graphs, lamps, and touch switches, on a screen. The screen data displayed by the NT31/NT31C are created by using the Support Tool at a per- sonal computer.
Page 24 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. Lamps These are graphics whose display status changes in accordance with the states of bits at the host.
Page 25 Touch switches 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: Stan- dard, shadow, 3-dimension, no display frame, rectangle, circle, polygon, sector When rectangle, circle, polygon, or sector is selected as the shape, the area within which pressing of the touch switch is sensed (the touch switch area) can be set independently of the position where the display graphic is set.
Page 26 Thumbwheel Switches 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.
Page 27 Alarm List/History 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.

Communications with the Host The NT31/NT31C is connected to the host by one of the following communica- tion methods. The following communications can be used to connect an OMRON PC: • Host link • 1:1 NT Link • 1:N NT Link (standard or high-speed) The following communications can be used to connect another companies’...
Page 30: Host Link
Communications with the Host The NT31/NT31C can directly write to and read from such allocated bits and words to change the display status of the elements on the PT screen, control the PT operating status, and notify statuses to the host. This function, which directly reads and writes the statuses of words and bits with- out using a PC program is called the direct connection function.
Page 31 PCs that can be connected with the 1:N connection NT Link method are as fol- lows: CQM1H, C200HX/HG/HE (-Z)E, CS1G/CS1H-E(V1). The NT31/NT31C also supports OMRON’s high-speed 1:N NT Link that pro- vides faster 1:N communications. The only PCs that support the high-speed 1:N NT Link are the -EV1 and higher versions of the CS1G/CS1H PCs.
