ABB CI853 3BSE018103R1 Communication Interface Baseplate

ABB CI853 3BSE018103R1 Communication Interface Baseplate

The ABB CI853 3BSE018103R1, also cataloged as the CI853 Communication Interface Baseplate, serves as the mechanical and electrical foundation for the CI853 RS-232 communication module in ABB automation systems.

Hardware Specifications

Backplane Bus Communication Velocity and Firmware Compatibility

The CI853 baseplate integrates with ABB 800xA and Advant Controller systems, ensuring deterministic backplane bus communication velocity. Firmware flash compatibility across controller revisions is preserved, allowing seamless upgrades. Trace spacing and grounding continuity suppress cross-talk, maintaining signal integrity during dense I/O scaling.

Frequently Asked Questions

Q: Is the CI853 baseplate required for module operation? A: Yes, the CI853 module must be mounted on the TP853 baseplate to function correctly.

Q: Does the baseplate support hot-swap? A: Yes, hot-swap operations are supported, allowing insertion and removal without powering down the system.

Q: Which protocols are supported through the CI853 interface? A: COMLI protocol (master/slave) and MODBUS RTU (master mode only).

Field Installation Guidelines

• Mount the CI853 module securely onto the TP853 baseplate to ensure mechanical stability.
• Route RS-232 cabling separately from high-current conductors to minimize EMI.
• Configure COMLI or MODBUS RTU parameters via system software before commissioning.
• Verify grounding continuity to support EMI filtering and signal integrity.
• Perform hot-swap operations only with trained personnel to avoid bus disruption.
