Description
The ABB CI867K01 (Part number 3BSE043660R1) is a high-performance Modbus TCP communication interface for the AC 800M controller series. It allows the System 800xA or standalone AC 800M controllers to communicate with external Modbus TCP devices such as PLCs, motor starters, and power meters over standard Ethernet.

Application Fields
The CI867K01 is used to bridge the AC 800M controller to third-party hardware:
- Energy Management: Interfacing with power meters and protection relays for electrical monitoring.
- Motor Control: Communicating with variable frequency drives (VFDs) and intelligent motor starters (e.g., ABB UMC100.3).
- Factory Integration: Connecting the 800xA system to localized PLCs (Siemens, Schneider, etc.) via Ethernet.
- Process Automation: Collecting data from remote I/O stations that use Modbus TCP as their primary protocol.
Product Usage Instructions
- Mounting: Snap the TP867 baseplate onto a DIN rail. Insert the CI867 module into the baseplate until it clicks, ensuring the side connectors are properly aligned with the AC 800M CPU or adjacent modules.
- Network Connection: Connect Ethernet cables to the RJ45 ports. For redundant networks, connect both ports to separate switches.
- Software Configuration: Use ABB Control Builder M to add the CI867 to the hardware tree. Configure the IP address and define the Modbus Slave/Master roles.
- Addressing: Map the Modbus registers (holding registers, coils, etc.) to the respective variables in your AC 800M application logic.
- Diagnostics: Monitor the “Run” and “OK” LEDs on the front panel. A flashing “Err” LED usually indicates a configuration mismatch or a loss of communication with the Modbus slave.
Product Technical Description
The CI867K01 functions as a dedicated co-processor for Ethernet-based communications. Technically, it handles the encapsulation of Modbus frames into TCP/IP packets, offloading this task from the main AC 800M CPU to ensure that control loop execution remains deterministic. It supports up to 130 slaves when acting as a Master and can handle multiple concurrent connections. Its dual-port design allows for various network topologies, including ring or star configurations, and supports the Media Redundancy Protocol (MRP) for high-availability applications.
Q&A (Common Questions)
Q: Can I use the CI867 for PROFINET or EtherNet/IP? A: No, the CI867 is dedicated to Modbus TCP. For PROFINET, you would need the CI871, and for EtherNet/IP, the CI873.
Q: Does the “K01” suffix include the baseplate? A: Yes, “K” denotes a kit. The CI867K01 includes both the active communication module and the TP867 termination baseplate.
Q: Is the CI867 hot-swappable? A: Yes, in a redundant configuration, the module can be replaced while the system is running without interrupting the control process.
Q: How many Modbus registers can it read per message? A: It follows standard Modbus TCP limits, typically allowing up to 125 16-bit registers per read request to ensure efficient bandwidth usage.
