PLC Setup
When connecting to a CVM1/CV-series CPU Unit, set the following communi-
cations conditions for the PLC Setup.
*1
Either set PLC Setup directly from a Programming Device (e.g. SYSMAC sup-
port software), or transmit the PLC Setup made at a Programming Device to
the CPU Unit.
For details on the PLC Setup, refer to the SYSMAC CVM1/CV500/CV1000/
CV2000 Operation Manual: Ladder Diagrams (W202-E1-@).
