The Allen‑Bradley 1756-RM is a redundancy module for the ControlLogix platform designed to enable 

controller‑redundancy in mission‑critical automation systems. When installed as a pair in two identical 

ControlLogix chassis (with matching modules and configuration), the 1756‑RM synchronizes controllers 

in real time, continuously monitors system health, and enables a seamless switchover from the primary 

controller to a secondary backup in the event of a fault — ensuring uninterrupted operation of the control 

system.
