Product Overview
The ABB CI855 Industrial Automation Module (3BSE018133R1) provides seamless MasterBus 300 (MB300) communication for the System 800xA AC 800M controller. This communication interface connects to the CEX-Bus through a baseplate, enabling robust data exchange between controllers and operator stations in Advant OCS installations.
Designed for modern plant modernization, the CI855 supports peer-to-peer communication between new System 800xA sections and existing MB300-based controllers such as Advant Controller 410, Advant Controller 450, and MasterPiece 200/1. This capability makes it an ideal bridge for hybrid plants integrating legacy and current automation systems.
Key Features & Benefits

Industry Applications
The ABB CI855 excels in process industries where legacy and modern control systems must coexist. For example, in a chemical plant expanding with System 800xA, the CI855 enables the new AC 800M controllers to communicate with existing Advant Controller 410 units, preserving investment in older hardware.
In power generation, the CI855 supports hot-swap maintenance, minimizing downtime during critical operations. Its marine certifications (BV, DNV-GL, LR) make it suitable for shipboard automation, where reliable communication is essential.
With line redundancy and clock synchronization, the CI855 ensures data integrity in distributed control systems, making it a dependable choice for continuous processes.
Installation & Setup
Mount the CI855 on the TP853 baseplate, which provides RJ45 connectors for two Ethernet ports and simplifies DIN-rail mounting. Connect the module to the CEX-Bus via the baseplate, then establish network connections using standard RJ45 cables. Ensure the module is inserted securely and that the hot-swap mechanism is engaged before powering up.
For redundant networks, connect both Ethernet ports to separate switches to achieve line redundancy. Verify that the 24 V DC supply is within the specified range and that the module draws no more than 150 mA to avoid overloading the bus.
Maintenance & Reliability
Routine inspection should focus on the RJ45 connectors for signs of wear or corrosion, especially in harsh environments. The CI855's IP20 protection requires installation in a clean, dry enclosure. Periodically check the baseplate mounting to ensure a secure fit.
Thanks to hot-swap capability, you can replace a faulty CI855 without stopping production, reducing downtime and maintenance costs. The module's compliance with G3 corrosion protection and RoHS standards ensures long-term reliability in demanding settings.
Compatibility & Integration
The CI855 is designed for use with the ABB AC 800M controller and is compatible with Advant OCS systems running Master software. It supports communication with legacy MB300-based controllers, including Advant Controller 410, Advant Controller 450, and MasterPiece 200/1. The module connects to the CEX-Bus via the TP853 baseplate, which provides two Ethernet ports for network redundancy.
With a maximum of 12 units on the CEX bus, the CI855 can be integrated into larger systems with multiple communication interfaces. Its Master role ensures it can coordinate data exchange across the network.
Buying Guide
When purchasing the ABB CI855, verify the article number 3BSE018106R1 to ensure you receive the correct revision. Confirm that your system uses the TP853 baseplate and that the CEX-Bus supports the module. Check the operating temperature range and IP20 protection rating against your installation environment.
