2 Installing the NB Unit and Connecting Peripheral Devices
When connecting to CS-Series CPU Units
For CS1G/H-CPU
Connection Methods
Connect to the RS-232C port built in the CPU Unit or the RS-232C port of the communication board.
When connecting to the peripheral port, a connection cable dedicated for the peripheral port is needed
(CS1W-CN118 type).
Only RS-232C can be used for connection.
PLC System Settings Area
When connecting to CS-Series CPU Unit, refer to the following table and set the communication
conditions as follows in [PLC System Settings] based on the communication port in use.
Connection Methods
Use the RS-232C port built
in CS1G/H, CS1G/H-H
Use the peripheral port of
CS1G/H, CS1G/H-H
*1 The communication speed should be set to the same value as that of the NB Unit.
[PLC System Settings] can be directly set with a peripheral tool (programming console), or it can be set
by transmitting the [PLC System Settings] set up by a peripheral tool (CX-Programmer) to the CPU
Unit.
For details about the [PLC System Settings], refer to SYSMAC CS Series Operation Manual (W339).
Settings for the front-side Switches
Set the DIP switches 4 or 5 as follows according to the NB-Series' port connected.
