The ABB CI855K01 (3BSE018106R1) is a specialized communication interface module designed for the AC 800M controller series. Its primary function is to facilitate high-speed, reliable data exchange via the MasterBus 300 (MB300) protocol. This enables AC 800M controllers to integrate seamlessly with legacy MasterView 800/1, MasterPiece 200/1, and Advant Controller 400 series systems, ensuring a smooth migration path or hybrid operation within a Distributed Control System (DCS) environment.

Application Fields
The CI855K01 is a critical component in large-scale industrial facilities that require cross-generational system communication:
- System Upgrades: Connecting modern AC 800M controllers to existing Advant OCS installations without replacing all hardware.
- Chemical & Petrochemical: Managing data flow between different processing units across a wide-area MB300 network.
- Steel & Metallurgy: Real-time monitoring of heavy machinery where legacy ABB controllers are still in operation.
- Power Plants: Ensuring synchronization between boiler control and turbine management systems across different ABB hardware platforms.
Product Usage Instructions
- Mounting: The CI855K01 is a CEX-bus module. Ensure the AC 800M Processor Unit is powered down. Mount the module onto the DIN rail and slide it into the CEX-bus connector on the left side of the CPU or the previous CEX-module.
- Cable Connection: Use certified MB300 cables. The 15-pin connector must be secured with the provided screws to prevent signal loss due to vibration.
- Software Configuration: Use ABB Control Builder M to configure the CI855 hardware. Define the node address and ensure the protocol settings match the existing MasterBus 300 network parameters.
- Redundancy Setup: If using redundant CI855 modules, ensure they are placed in adjacent slots and configured correctly in the hardware tree to allow for automatic failover.
- ESD Protection: Always handle the module by the plastic housing. Touching the internal circuitry without proper grounding can lead to immediate or latent failure.
Q&A – Frequently Asked Questions
Q: Can the CI855K01 be used with the PM860 controller? A: Yes, it is compatible with the PM860, PM864, PM866, and other PM8xx series controllers that support CEX-bus communication.
Q: Does the module support “Hot Swap” functionality? A: While the AC 800M system is robust, it is standard practice to perform hardware additions in a powered-down state or during a planned maintenance window to ensure the CEX-bus re-initializes correctly.
