PC Setup Area Settings

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

Item	Setting at Host
Communication mode	Host link mode
Communications speed	Set the same speed as set at the NT31/NT31C(*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 NT31/NT31C. For details, refer to Settings the Host Link Method (page160).

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

CX-Programmer support software).

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

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