The ABB CI854BK01 (consisting of the CI854B module and the TP854 Baseplate) is a high-performance communication interface designed for the AC 800M controller series. It enables seamless integration with PROFIBUS DP-V1 networks, allowing the controller to act as a Class 1 Master. This module is essential for connecting the control system to a wide array of field devices, including drives, sensors, and remote I/O, supporting both standard cyclic data exchange and acyclic communication for device configuration and diagnostics.

Product Instructions
The CI854BK01 kit should be mounted on a standard DIN rail. First, secure the TP854 Baseplate to the rail, ensuring it is properly grounded. The CI854B module is then plugged into the baseplate until the locking mechanism clicks. When wiring the PROFIBUS network, use standard purple Type A shielded cable. Ensure that the network is terminated correctly with 220-ohm resistors at both physical ends of the segment. Within the ABB Control Builder M software, the module must be added to the hardware tree of the AC 800M controller. The PROFIBUS GSD files for all connected slave devices must be imported into the software to define the I/O mapping. During operation, the “Run” LED indicates active communication, while the “Fault” LED will flash if there is a configuration mismatch or a loss of contact with one or more slave devices.
Q&A: Common Questions
What is the difference between the CI854A and the CI854B? The CI854B is the direct successor to the CI854A. It offers improved hardware reliability and is fully compatible with newer versions of the 800xA system software while maintaining backward compatibility for existing PROFIBUS DP-V1 networks.
Does this module support Master Redundancy? Yes, the CI854BK01 supports CPU and CEX-bus redundancy. In a redundant setup, two modules are used; if the primary module fails, the secondary module takes over the PROFIBUS communication without interrupting the process.
Can I configure slave devices through this module? Yes, because the CI854B supports DP-V1 acyclic communication, it allows for “tool routing.” This means you can use FDT/DTM technology to configure and calibrate smart field devices directly from your engineering workstation.
Why is my module showing a ‘Line Error’? A line error typically indicates a physical layer problem. Check for loose D-sub connectors, missing termination resistors, or electromagnetic interference caused by running communication cables too close to high-power motor leads.
