CI855-1 MasterBus 300 Communication Interface | ABB AC 800M Spare Parts
The ABB CI855-1 is a MasterBus 300 (MB300) communication interface module for ABB AC 800M distributed control systems. It connects to the CEX bus through a TP853 baseplate and provides two RJ45 Ethernet ports for MB 300 network redundancy.
A key advantage of the CI855-1 interface is that it enables peer-to-peer communication between new plant sections built on AC 800M / System 800xA and existing sections running MB 300-based controllers such as Advant Controller 410, Advant Controller 450, and MasterPiece 200/1.
- MasterBus 300 interface – Realizes MB 300 communication inside AC 800M via the CEX bus.
- Two RJ45 Ethernet ports – Baseplate TP853 provides two Ethernet ports for network redundancy.
- MB 300 network redundancy – Supports redundant MB 300 network configuration.
- Clock synchronization – Helps maintain consistent timing across connected devices.
- Dataset communication – Enables structured dataset exchange between controllers and network nodes.
- Peer-to-peer communication – Links AC 800M sections with legacy MB 300 controller sections.
- Hot-swappable – Supports module replacement during operation in applicable configurations.
- DIN-rail mounting – Simple DIN-rail installation on the baseplate.
- MB 300 communication in ABB AC 800M / System 800xA systems
- Integration of AC 800M controllers with Advant OCS / Master-based installations
- Peer-to-peer communication between new and existing plant sections
- Communication between controllers and operator stations
- System maintenance, replacement, and spare parts stocking
- Retrofit projects connecting AC 800M with Advant Controller 410 / 450 or MasterPiece 200/1

Public listings describe CI855-1 with the same functional description as CI855 / CI855K01 (order code 3BSE018106R1), but the exact order code for the CI855-1 designation is not consistently published. Before ordering, please confirm the nameplate order code, module revision, firmware version, and baseplate type (TP853) against your existing AC 800M hardware.
Some third-party pages claim CI855 supports PROFIBUS DP, Modbus TCP, EtherNet/IP, PROFINET, EtherCAT or CANopen. These claims are not confirmed here; verified references describe CI855-1 as a MasterBus 300 interface only.
