CS-series CPU Unit type: CS1G/H-CPU-EV1, CS1G/H-H
Connect to the built-in RS-232C port of the CPU Unit, or the RS-232C port of the
Communications Board. Note that the connection to a peripheral port must be made via an
RS-232C adapter (CS1W-CN118) specially designed for connecting to a peripheral port.
PLC Setup
When connecting to a CS-series CPU Unit, set the following communications conditions for
the PLC Setup area. Since the settings shown below are the PLC default settings for the CPU
Unit, no change to the PLC Setup is necessary as long as the communications speed is
maintained at 9600 bps.

Communications speed
Set the same baud rate as set at the NS-series PT (See note.)
Stop bits
2 stop bits
Parity Even
Data length

Unit No. for the host link
00
Note: Set the Host Link communications speed (baud rate) to 9600 bps or 19200 bps with
the Communications Setting menu item in the CX-Designer and the System Menu for
the NS-series PT. For details, refer to
1-4 Settings for Host Link
.
When the communications speed is set to 19200 bps., the PLC Setup of the CPU Unit
need to be changed.
Either set the PLC Setup directly from a Programming Device (Programming Console), or
transmit the PLC Setup made at a Programming Device (CX-Programmer) to the CPU Unit.
For details on PLC Setup, refer to the
SYSMAC CS series Operation Manual
(W339-E1-

).
