FAQ for CP1W-CIF11

Where does this option board install?
Installs in option board slot on CP1 CPU right side (between CPU and expansion units, if any). One option board per CPU.
What's the difference between CIF11 and CIF12?
CIF11: non-isolated RS-485. CIF12: isolated RS-485 (higher noise immunity). Choose CIF12 for noisy environments or when ground potential differences exist.
Can I use this for VFD communication?
Yes, common application. Configure as Modbus-RTU master, VFDs as slaves. Control speed, monitor status, read parameters. Most VFDs support Modbus-RTU.
How do I configure Modbus master?
Configure in CX-Programmer: set baud rate, parity, slave addresses. Use Modbus instructions (MODRD, MODWR) in PLC program to read/write slave registers.
