Redundant Processor Sync Module | Allen-Bradley 1785-BCM

Redundant Processor Sync Module | Allen-Bradley 1785-BCMProduct Overview The Allen Bradley 1785 BCM functions as a high reliability hardware interface designed to establish processor redundancy within the classic PLC 5 automation platform. This Backup Communication Module creates a dedicated, high speed deterministic link between a primary and a secondary PLC 5 chassis. The module transfers exact mirror images of user memory structures, data registers, and active I O tables across the synchronization link
