The ABB CI801 3BSE022366R1, also cataloged as the CI801 Communication Interface, operates as a dedicated hardware component for PROFIBUS DP-V1 network integration within S800 I/O platforms. This module provides direct physical execution of cyclic data exchange and acyclic configuration commands between the network master and distributed I/O stations.

Model Identification

The CI801 (3BSE022366R1) serves as a Fieldbus Communication Interface (FCI). It manages up to 12 S800 I/O modules, handling local data collection, supervision, and Output Set as Predetermined (OSP) states within the cluster.

Hardware Specifications

ABB Industrial Control & Drive Communication

The CI801 utilizes deterministic backplane bus communication velocity to interface with the S800 I/O backplane. It supports I/O density scaling and firmware flash compatibility, allowing for protocol-level adjustments and diagnostic enhancements. The module provides seamless integration with Profinet and EtherNet/IP deterministic networks when used in broader control architectures, ensuring that data packets are processed with minimal latency and high synchronization accuracy across the fieldbus.
