CI546 3BSE012545R1
Product Name
ABB CI546 3BSE012545R1 Multi-Protocol VIP Communication Interface Module for AC500/Advant OCS Systems(The naming follows ABB’s industrial module conventions:
- “CI546”: Identifies ABB’s “Communication Interface (CI)” series, with “546” specifying the multi-protocol VIP variant.
- “3BSE012545R1”: ABB’s global unique part number, where “3BSE” denotes automation components, “012545” is the specific model code, and “R1” indicates hardware revision 1.

- “Multi-Protocol VIP Communication Interface Module”: Highlights its core value—supporting Vendor Independent Protocol (VIP) and industrial protocols like Modbus/Profinet to enable cross-system data exchange.
This module acts as a “system communication bridge,” connecting ABB’s AC500 PLCs, Advant OCS DCS, and third-party devices while ensuring real-time data synchronization. )
2. Product Description
The CI546 3BSE012545R1 is an industrial-grade communication interface module engineered by ABB to address core challenges in automation integration: protocol incompatibility between heterogeneous systems, delayed data transmission, and limited connectivity in space-constrained cabinets. As a versatile component of ABB’s automation portfolio, it integrates 1 Mbps high-speed communication, multi-protocol support, and 16-bit parallel data transfer—making it indispensable for:
- Process Industries: Linking ABB AC800M controllers with Modbus-enabled sensors in chemical plants, ensuring real-time pressure/temperature data feedback.
- Manufacturing Lines: Connecting Panel 800 HMI with Profinet-based robots via Ethernet/IP, synchronizing assembly line operations.
- Energy Systems: Bridging Advant OCS DCS with CAN bus-powered power meters in power plants, enabling energy consumption monitoring.
- Building Automation: Integrating HVAC systems with ABB AC500 PLCs through Modbus RTU, optimizing energy efficiency.
