Overview
The 1785-BCM/C is the Backup Communications Module (Series C) in the Allen-Bradley PLC-5 series, used to build a dual-machine redundancy and high-speed communication switching architecture for PLC-5 systems. This module achieves data synchronization between the primary and backup PLC controllers via a high-speed link (HSSL) and automatically switches between the DH+ and Remote I/O communication channels in case of failure, thus ensuring continuous system operation.

Product advantages
Dual-machine redundancy architecture supports seamless switching between the primary and backup PLC-5 systems, ensuring continuous operation of the control system in case of failure.
High-speed communication synchronization enables real-time data synchronization between the primary and slave PLCs via a high-speed HSSL link, guaranteeing consistent control.
Multi-network compatibility supports DH+ and Remote I/O communication, adapting to traditional PLC-5 industrial network structures.
Enhanced system reliability allows automatic switching to the backup system in case of power failure, CPU failure, or communication anomalies.
Industrial-grade stable design is suitable for industrial environments with extremely high requirements for continuous operation, such as power and petrochemical industries.
