PLC Setup
When connecting to a CVM1/CV-series CPU Unit, set the following communi-
cations conditions for the PLC Setup.
Note
Set the Host Link baud rate at 9,600 bps or 19,200 bps with the memory
switch at the NT20.
Either set PLC Setup directly from a Programming Device (e.g., SYSMAC
Support Software), or transmit the PLC Setup made at a Programming Device
to the CPU Unit.
For details on the PLC Setup, refer to the
