Key Features
Compact Plug-In Option Board
The board installs into a compatible CPU option slot without requiring a separate external communication module enclosure or dedicated DIN rail position. Available installation slots depend on the specific host controller.
Compatible with Multiple Omron Controllers
Manufacturer documentation identifies support for CP1H, selected CP1L and CP1E models, CP2E-N, and additional supported controller platforms. Confirm the exact CPU model and option slot before installation.
Multiple PLC Serial Protocols
Depending on the connected CPU, the RS-232C port can support Host Link, no-protocol communication, 1:N NT Link, Serial PLC Link and selected serial gateway or Modbus-RTU functions.
Up to 15 m Serial Connection
Omron specifies a maximum RS-232C transmission distance of 15 m for applicable PLC configurations. The maximum permitted distance can be shorter at higher communication speeds or with particular host controllers.
No Independent Power Supply Required
The option board receives operating power through its compatible controller interface. Communication parameters and protocol operation are managed by the host controller rather than by a standalone processor inside the board.
Applications
- Omron PLC RS-232C communication expansion
- Industrial PLC-to-HMI serial connections
- PLC programming and maintenance interfaces
- Serial barcode reader communication
- Industrial weighing instrument integration
- Legacy serial device connectivity
- Factory automation controller communication
- Replacement of compatible CP1W-CIF01 option boards

Frequently Asked Questions
What is the Omron CP1W-CIF01?
It is an RS-232C serial communication option board that adds one serial port to a compatible Omron PLC or controller.
What connector does the CP1W-CIF01 use?
The board provides a female D-Sub 9-pin RS-232C connector. The required communication cable depends on the connected equipment.
How many serial ports does the board add?
It provides one additional RS-232C serial communication port per installed board.
Is CP1W-CIF01 compatible with Omron CP1H PLCs?
Yes. Omron lists CP1W-CIF01 for CP1H CPU units, with installation supported in option board slot 1 or 2.
Can CP1W-CIF01 be used with CP1L controllers?
Yes, with compatible CP1L CPU models. It cannot be used with 10-point CP1L CPU units, which do not support this option board. Confirm the exact controller designation.
Does the board work with CP1E and CP2E PLCs?
It is supported by selected CP1E-N and CP1E-NA CPUs and compatible CP2E-N models. Not every CP1E or CP2E version includes an applicable option slot.
What is the maximum RS-232C cable length?
The general maximum transmission distance is 15 m for supported PLC configurations. For certain G9SP configurations, Omron specifies 15 m at 9600 bps and 3 m at 115200 bps.
Does CP1W-CIF01 support Modbus communication?
Selected compatible Omron CPUs support Modbus-RTU Easy Master functions through their serial ports. The CP1W-CIF01 provides the physical RS-232C interface, while the connected controller determines supported protocol functions.
Can this option board connect a PLC to a computer?
Yes. It can support compatible serial communication with a computer using an appropriate RS-232C cable, such as Omron XW2Z series cables, and the correct software and communication settings.
Does CP1W-CIF01 require a separate 24 VDC supply?
No. It is powered through the compatible host controller's option board interface and does not require a separate external power supply.
What is the difference between CP1W-CIF01 and CP1W-CIF11?
CP1W-CIF01 provides an RS-232C interface with a D-Sub 9-pin connector. CP1W-CIF11 provides a non-isolated RS-422A/RS-485 interface. The communication interfaces and wiring requirements differ.
What should be checked before ordering?
Confirm the exact model CP1W-CIF01, the host PLC or controller model, available option board slot, required RS-232C interface, D-Sub 9-pin connector, communication protocol, baud rate, cable pinout, cable length and compatibility with the connected serial device.
