PLC Setup
When connecting to a CVM1/CV-series CPU Unit, set the following communi-
cation conditions for the PLC Setup.
*1 Set the Host Link baud rate at 9,600 bps or 19,200 bps with the Comm.
Speed memory switch at the NT11. For details, refer to Setting the Host
Link Method (page 74).
Set the PLC Setup directly from a Programming Device (e.g., SYSMAC Sup-
port Software).
For details on the PLC Setup, refer to the SYSMAC CVM1/CV500/CV1000/
CV2000 Operation Manual: Ladder Diagrams (W202-E1- @ ).
