Connecting to the RS-232C Port at the Host Section 4-1
Connect to the built-in RS-232C port on the CPU Unit or to an RS-232C port
on a Communications Board. A special Peripheral Port Connecting Cable
(CS1W-CN118) can be used to connect to the peripheral port.
PLC Setup
When connecting to a CS/CJ-series CPU Unit, set the following communica-
tions conditions for the PLC Setup, in accordance with the communications
port to be used.
Using the CPU Unit’s Built-in RS-232C Port
*1
Set any value between 0000 and 0009 Hex for the communications baud
rate. The same baud rate will be used regardless of the value as long as it
is between 0000 and 0009 Hex.
Using the CPU Unit’s Peripheral Port
*1
Set any value between 0000 and 0009 Hex for the communications baud
rate. The same baud rate will be used regardless of the value as long as it
is between 0000 and 0009 Hex.
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.
For details on the PLC Setup, refer to the CS-series Operation Manual
(W339) or the SYSMAC CJ Series Operation Manual (W393).
Setting the Front Switches
Set the CPU Unit’s DIP switch to 4 or 5 in accordance with the port NT31/
NT31C is connected to. An example of a CS-series CPU Unit is shown below.
