Serial communication module for CP1 PLCs
The CP1W-CIF12-V1 is an Omron serial option board for CP1-series PLCs, adding an RS422/485 port rated for 500 m long-range communication. It mounts on the CPU or expansion bus, giving the PLC a dedicated serial channel for Modbus, protocol macro, or host link networks without consuming the built-in RS232 port.
Long-range link characteristics
The module provides RS422/485 serial communication up to 500 m.
Sourcing and integration
Supplied in bulk packaging (typically a single unit per bag). The module is supported by Omron's CX-Programmer for configuration; no special DIP switches are needed—the baud rate and protocol are set in the PLC setup. For BOM fill, this order code is the exact match for a CP1W-CIF12-V1 slot; no cross-reference exists in Omron's current range.
