Page 20: Principal Functions Of Nt31/Nt31C
Functions of the NT31/NT31C Section 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 21 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 22: 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 23 Section 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. Mark Image data Library data Lamps...
Page 24 The input character strings can also be stored in a character string memory table and notified to the host. String inputs can be enabled and disabled from the host when an interlock bit has been allocated. Character string setting input field Display NT31C Input NT31C NT31 NT631C...
Page 25 Section 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 26 ON are recorded and displayed together with the message (charac- ter 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.
Page 27: System Configuration
System Configuration Section 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 (page 279). 1-3-1 Peripheral Devices That Can Be Connected The following peripheral devices can be connected to an NT31/NT31C.

Page 29: Host Link
The direct connection function allows the data to be displayed at the NT31/NT31C to be read from the memory area in the PLC and written to memory tables in the NT31/NT31C. Also, the data input at the NT31/NT31C can be writ- ten to the memory area in the PLC.
Page 30 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 31: 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 32: Comparison Between Direct Connection And Memory Link
1-5-3 Memory Link Online Transfer Function When memory link communications are being used, the NT31/NT31C can be switched to Transmit mode from the host even if the NT31/NT31C is operating and screen data can be written. (The NT31/NT31C can be returned to RUN mode after the screen data is written.)

Page 254: Replacing The Battery
The NT31/NT31C uses a lithium battery to back up the memory contents. The battery life is about 5 years if the NT31/NT31C is used in a location where the ambient temperature is 25_C. If the temperature at the location of use is higher than this, the battery life will be shorter.
Page 255: Inspection And Cleaning
The connector of the new battery must be connected within 5 minutes after disconnecting the old battery’s connector. However, the battery can be re- placed while the NT31/NT31C power is on, and in this case there is no time restriction.
Page 256 Inspect the following points to determine if there is any divergence from the stated criteria. If there is, either improve the surrounding environment so that the values fall within the stated range, or adjust the NT31/NT31C, for example by re-tightening screws.
Page 257 S Be sure to switch the power OFF before starting replacement. S After replacement, check that the new NT31/NT31C is not subject to the same error. S If a faulty unit is returned for repairs, write as detailed a description of the fault as possible and send this description together with the unit to the OMRON ad- dress indicated on the back cover of this book.
