The CI547 (3BNP004429R1) is a high-performance communication interface module for the ABB ABB MasterPiece 200 Control System and ABB Advant OCS architectures.
It operates within the Masterbus 300 network, enabling reliable peer-to-peer communication between controllers and field subsystems. The module includes an onboard slave processor dedicated to communication protocol handling, which reduces processing load on the main PM150 processor module, improving real-time control determinism and reducing scan jitter in large DCS networks.
The CI547 is commonly used for legacy system maintenance and expansion, providing stable communication performance in long-life industrial installations.

Q1: How does the onboard slave processor improve performance?
The slave processor manages Masterbus 300 communication tasks independently, allowing the main CPU to focus on control logic execution and reducing network-related processing delays.
Q2: Is it compatible with modern ABB 800xA systems?
The module is primarily designed for legacy systems. Integration with ABB 800xA System requires gateway or connectivity server solutions supporting Masterbus protocols.
