Description
1. At-A-Glance Executive Brief
- Model: CI858K01 / 3BSE018135R1
- Brand: ABB
- Part Type: Profibus DP Communication Interface Module
- Lifecycle status: Active / Maintained
- Weight: 0.30 kg
- Core Protocol: Profibus DP-V1 / DP-V2 Master
2. Technical Introduction
Communication dropouts on fieldbus loops frequently trigger unnecessary controller trips and obscure true process alarms, stalling production across continuous manufacturing lines. Plant engineers face significant hurdles when legacy master modules fail without immediate hot-swap capability. The ABB CI858K01 (3BSE018135R1) mounts directly onto the AC 800M controller rack to deliver deterministic Profibus DP communication, maintaining high-speed cyclic data exchange with remote I/O islands and drives while supporting redundant master configurations for maximum process uptime.
3. Core Technical Specifications
- Manufacturer: ABB
- Catalog Number: CI858K01
- Part Number: 3BSE018135R1
- Communication Protocol: Profibus DP-V1 / DP-V2
- Bus Connection: 9-pin D-sub female connector
- Mounting: CEX-bus / S800 I/O Rack
- Environmental Tolerance: Please refer to the OEM datasheet for complete environmental tolerances.
4. Field Engineer’s Tech Notes
- Bus Termination Verification: Ensure that active bus terminators at both physical ends of the Profibus trunk are powered continuously; a loss of termination power will cause intermittent node dropouts across the entire segment, even if the CI858K01 hardware functions normally.
- Redundancy Switchover Settings: When configuring redundant CI858K01 pairs, verify that slave device parameterization matches precisely in Control Builder M to prevent configuration mismatch faults during an automatic primary-to-backup switchover event.
5. Adaptive QA & Testing Protocol
Our testing protocol for this communication interface involves mounting the unit on a live AC 800M test rack to verify backplane communication and CEX-bus health. We connect the D-sub port to a Profibus network simulator to validate baud rate auto-detection, master handshake stability, and cyclic data throughput under full node load. Diagnostic status logs are captured during testing and can be provided upon request.
6. Buyer’s FAQ
