Page 23: Comparison Between Nt31 And Nt31C
1-2-2 Comparison between NT31 and NT31C Two NT31 models — the NT31, which is capable of versatile graphic displays, and the NT31C, which is also capable of color display — are available. The differences between the NT31 and NT31C are tabled below:...

This is the capacity of the flash memory that stores screen data. The values are the same as the NT30/NT30C when the PT is in NT30/620 compatible mode. For differences in programming, refer to Appendix B in the NT31/NT31C/NT631/NT631C Programmable Termi- nal Reference Manual.
Page 25: Principal Functions Of Nt31/Nt31C
Functions of the NT31/NT31C 1-2-4 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 26: Recipe Function
Communications with the host The NT31/NT31C can communicate with the host by four methods: host link, 1:1 NT Link, 1:N NT link (standard or high-speed), and Memory link. Data can be read from the host, and data input by means of touch switches and numeral/character string settings can be sent to the host.
Page 27: Displays
The NT31/NT31C can display various kinds of elements such as characters, numeric 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 personal computer. Characters...
Page 28 Functions of the NT31/NT31C Section 1-2 Mark Image data Library data Lamps These are graphics whose display status changes in accordance with the states of bits at the host. Squares, circles, sectors and polygons can be used for lamps (normal (standard) lamps). In accordance with the status of the host bit, they can be lit (displayed in reverse video) or flashed (repeated alternation between normal and reverse video display states).
Page 29 Functions of the NT31/NT31C Section 1-2 The following 8 types of display graphic can be used for touch switches: Stan- dard, shadow, 3-dimension, no display frame, rectangle, circle, polygon, sec- 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 30 Section 1-2 Functions of the NT31/NT31C 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 notification sent to the host.
Page 31 ON are recorded and displayed together with the message (character string) set for the bit memory table. The NT31/NT31C allows selection of the display order as the newest record first or the oldest record first by memory switch setting.

Section 1-3 System Configuration System Configuration This section shows the configuration of a system that uses an NT31/NT31C. For details on product models, refer to Appendix J Model List. 1-3-1 Peripheral Devices That Can Be Connected The following peripheral devices can be connected to an NT31/NT31C.

(1:1) communications method, RS-485 cannot be used. The connection must be made with RS-232C or RS-422A. Communications with the Host The NT31/NT31C is connected to the host by one of the following communi- cations methods. The following communications can be used to connect an OMRON PLC: •...
Page 34: Host Link
PLC memory. • Since the NT31/NT31C can directly refer to PLC bit and word data without using the program at the PLC, it can be connected to the PLC without changing the PLC program which controls the currently running produc- tion line.
Page 35 NT31/NT31C switches to the monitor mode when the PLC is in the RUN mode.) • In the case of PTs that support the standard 1:N NT Link (NT20S, NT31, NT31C, NT600S, NT620S, NT620C, NT625C, NT631, NT631C) up to 8 PTs can be connected to one port of the PLC and used at the same time.
Page 36: Communications Using Memory Links
In memory link, there is an area called PT Memory, as shown below, inside the NT31/NT31C, and this area is treated as a virtual area on the PLC. This allows PT memory and the display elements of the NT31/NT31C to make a quasi-direct connection.
Page 37: Comparison Between Direct Connection And Memory Link
RS-232C/422A communications In the memory link method, the only difference is that the NT31/NT31C finds its communications target inside instead of outside. In the memory link method, therefore, change of the target is all that is needed to be capable of using the exact screen data that is acquired by the direct connection.

Note that only the screen data is cleared (initialized), and the memory switch settings and the display history/alarm history record data are retained.
Page 172: Transmitting The Screen Data
On completion of screen data clearance, the NT31/NT31C returns to the Sys- tem Installer mode menu screen. After the screen data has been cleared, if an attempt is made to set the NT31/ NT31C to the RUN mode before screen data has been transmitted from the Support Tool or Memory Unit, an error message will be displayed and the RUN mode will not be established.
Page 173 (It is not possible to transmit mathematical table data in data units.) When data is transmitted in file units, all of the screen data in the NT31/ NT31C is cleared and then the new data is transmitted.
Page 174 If any of the following, or a system error, occurs during transmission of screen Observed When data, the transmitted screen data will not be registered correctly in the NT31/ Transmitting Screen Data NT31C. If this happens, the NT31/NT31C may not enter the RUN mode when started up, or there may be unpredictable malfunctions such as failure to dis- play screens during operation.
