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.
