BCNet ‑ CP Ethernet Module for Omron CP Series PLC

by


BCNet‑CP adds Ethernet and Modbus TCP integration to Omron CP1L/E/H PLCs—plug‑and‑play, ideal for SCADA and HMI networking.

Product Overview
BCNet‑CP is an affordable Ethernet communication processor made for Omron CP1L/CP1E/CP1H PLCs. It plugs into the PLC’s DB9 serial port, enabling simultaneous programming software, touch screen, and SCADA access without occupying the original port. It supports Omron FINS TCP/UDP, Modbus TCP, BCNetTCP, and allows up to 10 TCP/UDP connections including advanced communication modes (CX Programmer, SCADA, OPC, VB/C# etc.) . Ideal for production monitoring and equipment digitalization .

How to Use

  1. Plug BCNet‑CP directly into CP1L/E/H PLC’s DB9 serial port—no extra wiring required.
  2. If needed, provide external 24 V DC (it can also draw power from serial port).
  3. Access the built‑in Web UI default IP (192.168.1.178) or use BCDevice tool for diagnostics and setup.
  4. Configure communication modes: FINS TCP/UDP, Modbus TCP or BCNetTCP, map PLC data to Modbus registers automatically.
  5. Connect HMI, SCADA, or OPC server software to module via Ethernet.
  6. Optionally update firmware via Ethernet.
    Tips: ensure your network and PLC serial baud rates match; use CX‑Programmer for PLC compatibility; check IP and subnet correctness.

User Review Summary
Limited public reviews available, but common feedback from sellers indicates low cost, compact design, and easy setup. Pros: plug‑and‑play integration without occupying PLC port, support for multiple protocols, stable performance. Cons: minimal user support from manufacturer, limited direct user feedback, documentation basic and occasionally unclear.

Comparison with Competing Products
BCNet‑CP versus Omron CP1 Ethernet option: CP1 Ethernet units are expensive and require CPU replacement; BCNet‑CP is cheaper plug‑in add‑on.
Compared to generic RS‑232‑Ethernet converters: BCNet‑CP auto‑maps PLC data, supports FINS protocol and SCADA integration—generic converters often lack PLC‑specific compatibility and protocol support.
