New Original Omron CP1W-CIF12-V1 Programmable Controller CP1L Communication Board
1. Product Overview
The CP1W-CIF12-V1 is an original isolated RS-422A/485 communication option board designed exclusively for Omron SYSMAC CP series compact PLCs, including CP1L, CP1H and CP2E CPU units. It serves as an expandable serial communication accessory that plugs directly into the built-in option slot of CP-series controllers to add a long-distance differential serial port.
This V1 upgraded version adopts full electrical isolation circuit design between PLC internal bus and external serial bus, effectively suppressing surge interference and ground loop noise in multi-device networking scenarios. It supports a maximum transmission distance of 500 meters, far exceeding non-isolated RS485 boards, making it ideal for distributed automation equipment such as production line inverters, temperature controllers, weighing transmitters, remote sensor clusters and multi-PLC interconnection systems.
As factory-new genuine hardware, the communication board passes strict EMC aging and signal stability testing. Each CP1L/CP1H CPU reserves two independent option slots, allowing users to install up to two CP1W-CIF12-V1 boards simultaneously to build multi-channel serial networks without replacing the main PLC controller. It works seamlessly with CX-Programmer and CX-Integrator software for one-click communication parameter configuration and online data monitoring.
2. Main Functions
2.1 Isolated RS-422A/485 Serial Communication
- Differential signal transmission via terminal block wiring, compatible with RS-422 full-duplex and RS-485 half-duplex wiring modes
- Galvanic isolation between internal PLC circuit and external field bus to eliminate ground potential difference interference
- Supports multi-drop bus topology, allowing up to 32 slave devices connected on one serial trunk line
- Terminal block with screw-type fasteners for secure field wiring with ferrite cable terminals
2.2 Multi Industrial Protocol Compatibility
- Modbus RTU master/slave mode for communication with third-party inverters, thermostats, meters and testing instruments
- Omron native FINS protocol for data exchange between multiple CP-series PLCs
- Host Link protocol for connecting touch HMIs, text displays and upper monitoring industrial computers
- No-protocol transparent transmission mode to read raw serial data from barcode scanners and testing sensors
2.3 Flexible System Expansion & Configuration
- Installs in either Slot 1 or Slot 2 of CP1L / CP1H CPU; two boards can be mounted for dual independent serial networks
- Plug-and-play hardware design; no extra power wiring required, powered directly through the PLC’s internal backplane bus
- All communication parameters (baud rate, parity, data bits, stop bits, station address) set within CX-Programmer software
- Dedicated internal data register buffers reserved for serial transmit and receive data storage
2.4 Signal & Fault Diagnosis
- Built-in transmit/receive LED indicator lights to visually display real-time serial data transmission status
- Hardware short-circuit and overvoltage protection for external serial wiring faults
- PLC system alarm code feedback for communication disconnection, wiring errors and bus overload failures
