ControlLogix High-Speed Redundancy Communication
The 1756-RM2K operates within the ControlLogix backplane architecture and provides dedicated controller synchronization through a 1 Gbps LC fiber optic redundancy communication link. The kit configuration includes required redundancy accessories to support installation of paired controller chassis assemblies.
Firmware flash compatibility is required between redundant controllers, redundancy modules, and associated communication components. The module supports deterministic synchronization of controller states and provides diagnostic information through integrated module status indicators.
The ControlLogix platform supports I/O density scaling through matched redundant chassis configurations. The redundancy communication path operates independently from standard application networks to maintain dedicated synchronization data exchange.
Frequently Asked Questions
Q: What components are included in the 1756-RM2K configuration?
A: The 1756-RM2K is a redundancy kit configuration based on the 1756-RM2 module and includes compatible redundancy cable accessories.
Q: What fiber optic connection is used for redundancy communication?
A: The module uses an LC fiber optic connector with a 1 Gbps communication link between redundant chassis assemblies.
Q: Does the 1756-RM2K require matched controller configurations?
A: Yes. Redundant operation requires compatible controller hardware, matching chassis configurations, and compatible firmware revisions.
Field Installation Guidelines
Install the 1756-RM2K kit in compatible ControlLogix chassis assemblies according to the chassis installation requirements. Verify that both redundant chassis contain matching controllers, supported communication modules, and compatible firmware versions.
Connect the supplied fiber optic redundancy cables using proper optical handling procedures. Route fiber cables separately from high-voltage wiring, motor circuits, and strong electromagnetic interference sources.
Confirm chassis grounding, power supply compatibility, and backplane power availability before enabling redundancy functions. Apply standard industrial cabinet practices for cable segregation, shielding, and enclosure grounding.
