Description
The ABB CI867K01 (Part Number: 3BSE043660R1) is a high-performance communication interface kit designed for the AC 800M controller series within the ABB Ability™ System 800xA. This module enables the controller to communicate with external devices and systems using the MODBUS TCP protocol over Ethernet.
Product Introduction
The CI867K01 is a dual-channel Ethernet interface that acts as a gateway for the AC 800M processor. It allows the PLC to function as either a Modbus TCP Master or a Modbus TCP Slave. This flexibility makes it ideal for integrating a wide variety of third-party equipment—such as variable speed drives, motor protection relays, power meters, and specialized analytical instruments—into the 800xA control environment.
The “K01” suffix indicates a complete kit, which typically includes the CI867 Communication Interface and the TP867 Baseplate. The module features a rugged industrial design and supports redundancy, ensuring that critical communication links remain active in the event of a hardware or cable failure.

Technical Description
The CI867 module handles the translation between the internal CEX-Bus (Communication Expansion Bus) of the AC 800M and the standard Ethernet frames required for Modbus TCP.
- Dual Ports: The two ports can be used to create separate networks or for media redundancy.
- Slave Capacities: In slave mode, the module can handle multiple concurrent connections from different masters.
- Master Capacities: In master mode, it can poll hundreds of data points from multiple slave devices using configurable scan rates.
Product Usage Instructions
1. Hardware Mounting
- Ensure the AC 800M controller is powered off.
- Attach the TP867 Baseplate to the DIN rail on the right side of the CPU or an existing CEX-Bus extension.
- Snap the CI867 module onto the baseplate. Ensure the plastic locking clips are securely engaged.
2. Network Wiring
- Connect Category 5e (or better) shielded Ethernet cables to the RJ45 ports.
- If using redundancy, connect Port 1 and Port 2 to separate industrial switches.
3. Software Configuration
- Open ABB Control Builder M.
- Add the CI867 module to the hardware tree under the CEX-Bus.
- Configure the IP address, Subnet Mask, and Gateway.
- Define the Modbus mapping (registers, coils, and floating-point data) to correspond with the field devices.
Common Problems Q&A
Q: Can I use the CI867 ports for standard Ethernet/IP or PROFINET? A: No. The CI867 is dedicated to the Modbus TCP protocol. For PROFINET, you would require the CI871 module, and for Ethernet/IP, the CI873 module is used.
Q: What does a flashing “ERR” (Error) LED indicate? A: A flashing red Error LED usually indicates a configuration mismatch (e.g., an IP address conflict) or a failure in the communication between the module and the AC 800M CPU over the CEX-Bus.
Q: Is the CI867K01 hot-swappable? A: While the AC 800M system is robust, it is highly recommended to follow the “Replaceable Unit” procedures in the ABB manual. In a redundant setup, you can replace a faulty module without stopping the process, provided the secondary module is “Active.”
Q: How many CI867 modules can I add to a single AC 800M controller? A: A single controller can typically support up to 12 communication interface modules, though the total power consumption on the CEX-Bus must be calculated to ensure it does not exceed the limit.
