Description
The ABB 3BSE018105R1, commonly designated as the CI855, is a high-performance communication interface module designed for ABB’s System 800xA distributed control architecture. This module serves as a specialized network bridge, enabling AC 800M controllers to connect and communicate seamlessly with legacy Advant OCS systems via the MasterBus 300 (MB 300) protocol. Engineered to protect existing infrastructure investments, it facilitates high-speed, deterministic data exchange, sequence-of-events tracking, and system-wide synchronization between different generations of ABB automation control loops.

Key Application Fields
- Plant Infrastructure Upgrades: Integrates modern AC 800M control processors into older processing lines running Advant Controller 410/450 hardware.
- Power Generation Stations: Manages high-speed data handshakes between centralized management consoles and remote substation nodes.
- Chemical and Pharmaceutical Lines: Transmits time-stamped process parameters across segregated production areas without latency.
- Pulp and Paper Mills: Aggregates real-time diagnostic telemetry from legacy drive arrays to upgraded operator workstations.
- Metallurgical Processing Plant: Maintains real-time synchronization of complex motor and thermodynamic parameters across shared data networks.
Product Instructions & Guidelines
- Electrostatic Protection: Always use a properly grounded anti-static wrist strap when handling the CI855 module to prevent static discharge from damaging the internal surface-mount microelectronics.
- CEX-Bus Mounting: Slide the module carefully onto the standard DIN-rail adjacent to the AC 800M controller. Align the integrated CEX-Bus side connectors and push firmly together until the locking mechanisms click into place.
- Address Configuration: Set the required MasterBus 300 network node address and cluster address using the hardware dials or software parameters before initializing the communication loop.
- Software Configuration: Configure the module hardware footprint using ABB Control Builder M software. Define the dataset allocations, transmission intervals, and exception reporting rules matching your system topology.
- System Maintenance: Routinely verify the operational status via the integrated front-panel LEDs (“Run”, “Fault”, and “Traffic”). Ensure the cabinet cooling slots are unblocked to prevent thermal buildup on the communication card.
Q&A – Frequently Asked Questions
- Q: What is the main purpose of the CI855 module within an ABB network?
- A: It allows newer AC 800M controllers to read and write peer-to-peer data directly to legacy Advant Controller 400 series systems using the MasterBus 300 protocol without needing third-party gateways.
- Q: Can the CI855 interface module be hot-swapped while the system is powered?
- A: Yes, the CI855 supports hot-swapping on the CEX-Bus under a running configuration, provided that the system configuration guidelines for redundant or isolated modules are fully met.
- Q: What do the front-panel “Run” and “Fault” LEDs indicate during a system conflict?
- A: A steady green “Run” LED indicates proper internal power and runtime processing. A red “Fault” LED indicates an internal self-test failure, while a flashing amber light indicates missing communication or mismatched parameters on the MB 300 network layer.
- Q: Does this module require an independent external power cable connection?
- A: No, the CI855 draws its required operating voltages directly from the standard CEX-Bus connection provided by the adjacent controller backplane base unit.
