Functions of the NT631/NT631C 1-2-5 Displays Characters (fixed display) Fixed Displays The NT631/NT631C can display various kinds of elements such as charac- ters, numeric values, graphs, lamps, and touch switches, on a screen. The screen data displayed by the NT631/NT631C are created by using the Sup- port Tool at a personal computer.
Page 30 Functions of the NT631/NT631C 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 32 Functions of the NT631/NT631C 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. Thumbwheel switch inputs can be enabled and disabled from the host when an interlock bit has been allocated.

Page 36: Host Link
Communications with the Host The words and bits allocated for direct connection are called the allocated words and allocated bits. The direct connection function allows the data to be displayed at the NT631/ NT631C to be read from the memory area in the PLC and written to memory tables in the NT631/NT631C.
Page 37 Communications with the Host The NT631/NT631C also supports OMRON’s high-speed 1:N NT Link that provides faster 1:N communications. The only PLCs that support the high- speed 1:N NT Link are CS1G/CS1H PLCs of version -EV1 and higher, CS1D PLCs, and CJ1G/CJ1H/CJ1M PLCs.

Page 80 Connecting to the RS-232C Port at the Host PLC Series CVM1 Series CompoBus/ S Master Control Unit Reference: CS/CJ-series CPU Units cannot be connected with the 1:1 connection NT link method. Use the 1:N connection NT link method (standard or high-speed) instead to make the 1:1 connection.
Page 81 Connecting to the RS-232C Port at the Host Connecting to a CPM2C The CPM2C PLCs do not have the same kind of port connectors found on CS/ CJ-series PLCs. The CPM2C’s communications port handles both RS-232C and peripheral port connections which are divided internally. Therefore, when using the CPM2C, it is necessary to select RS-232C or peripheral port con- nections, according to the kind of cable and port (on the cable) used, as shown in the following table.
Page 82 Compatible Host Units Method The OMRON PLCs that can be connected using the NT link (1:N) method are the CS/CJ-series CPU Units and the C-series C200HX/HG/HE(-Z)E, CQM1H, and SRM1 only. With the CS/CJ-series PLCs, it is possible to connect a 1:N NT Link using a Serial Communications Board (CS Series only) or a Serial Communications Unit.
Page 83 Connecting to the RS-232C Port at the Host Check the model and series of the PLC as well as the model of Serial Com- munications Board or Unit being used before making the connections. The hosts that can be connected to the NT631/NT631C by the NT link (1:N) method using the RS-232C ports of both Units are indicated in the table below.
Page 84 Connecting to the RS-232C Port at the Host Reference: Version 1 (-V1) and high-speed versions (H) of the CS-series and CJ-series CPU Units support the high-speed 1:N NT Link method in addition to the standard 1:N NT Link method. Furthermore, the high-speed 1:N NT Link method can be used in earlier versions of CS-series CPU Units by installing the latest version of a Serial Communications Board or Unit.
Page 85 Connecting to the RS-232C Port at the Host Using the CPU Unit's Built-in RS-232C Port Using the CPU Unit's Peripheral Port When connecting PT with its model number 0, 2-5 to the built-in RS-232C port, for example, set the value 8200 Hex to 160 CH, and 0005 Hex to 166CH. Either set PLC Setup directly from a Programming Device (Programming Con- sole), or transmit the PLC Setup made at a Programming Device (CX-Pro- grammer) to the CPU Unit.
Page 86 Connecting to the RS-232C Port at the Host CPU Unit Allocation DM Area Settings Setting is written from the Programming Device (a Programming Console or CX-Programmer) directly into the allocation DM area (system setting area) of the CPU Unit. After the setting is written, it becomes effective by turning the power ON, restarting the Unit, restarting the communications port, or execu- tion of the STUP command.
Page 87 Connecting to the RS-232C Port at the Host Using the High-speed NT Compatible Host Units Link (1:N) Method The high-speed 1:N NT Link method can be used with version 1 (-V1) and high-speed versions (H) of the CS-series and CJ-series CPU Units.
