[PC system settings]
When connecting to a CVM1/CV series CPU, set the following communication
conditions for the “PC system settings”.
Item Setting at Host
Communications speed Set the same speed as for 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
“Comm. Speed” memory switch at the NT31/NT31C. For details, refer to “Setting
the Host Link Method” (page 175).
Either set PC system settings directly from a peripheral tool (e.g. SYSMAC sup-
port software), or transmit the PC system settings made at a peripheral tool to
the CPU.
For details on the PC system settings, refer to the SYSMAC CVM1/CV500/
1000/2000 User’s Manual (Ladder) (W202).
