PLC Setup Area Settings

When connecting to a C200HS, C200HX/HG/HE(-Z)E, CPM1, CPM2A, CPM2C, CQM1, or CQM1H CPU Unit, or SRM1, set the following communi- cations conditions for the PLC Setup area.

Item	Setting at Host
Communications mode	Host link mode
Communications speed	Set the same speed as set at the NT631/NT631C(*1)
Stop bit	2 stop bits
Parity	Even
Data length	ASCII 7 bits
Unit #	00

*1 Set the host link communications speed at 9600 bps or 19200 bps with the memory switch at the NT631/NT631C. For details, refer to 6-7-2 Setting the Host Link Method (page 155).

Set the PLC Setup area settings directly from a Programming Device (e.g.

CX-Programmer).

For details on operations relating to the PLC Setup area, refer to the manual for the PLC which is used.

The PLC Setup area word numbers and settings to be made depending on the Unit and port to which the connection is made are shown below.
