1756-RM2
The Allen-Bradley 1756-RM is a ControlLogix Redundancy module. This module may only be used with the ControlLogix
platform to enable controller redundancy. It manages connectivity of Two (2) identical controllers, installed in an
identical rack of the same components and configuration. It provides redundancy system monitoring as well as
module health via the embedded LED display such as PRI, COM and OK.
The 1756-RM has been released as Series A and B. Series is basically an enhancement of the previous series
however, a 1756-RM with different series can co-exist in one redundant configuration. It is highly recommended to
have the same series installed to achieve maximum operability of the redundancy setup. When used with the same series of redundancy module, speed of 100 Mbps is achieved.
