GE Fanuc IC697RCM711C Series 90-70 Redundancy Communications Module
Configured for hot standby CPU synchronization in Series 90-70 PLC platforms, the GE Fanuc IC697RCM711C (IC697RCM711 Redundancy Communications Module) provides direct physical/electrical execution. This single-slot module transfers I/O data and program state parameters between primary and backup controllers over dual fiber optic links at 200 Mbit/s to enable automatic failover execution.

Brand-Specific Hardware Architecture
The backplane bus communication velocity across the Series 90-70 rack enables real-time memory image replication to keep the secondary CPU synchronized with the primary controller. The module transfers data over dual-redundant fiber channels, bypassing local backplane bottleneck limits while delivering galvanic isolation against high field surge voltages. Firmware flash compatibility checks automatically validate operating revisions between primary and backup processors during initialization to ensure deterministic failover execution.
Frequently Asked Questions
Q: Can the IC697RCM711C module be removed or inserted into the Series 90-70 rack while backplane power is applied?
A: No, technicians must power down the baseplate before removing or inserting the IC697RCM711C module to prevent backplane bus logic corruption and optic transceiver damage.
Q: What optical connector type and fiber cable specifications are required to interlock two IC697RCM711C modules?
A: The module interface requires dual ST connectors paired with 62.5/125 um multimode fiber optic cabling, maintaining a total point-to-point cable length under 500 meters.
Field Installation Guidelines
Mount the IC697RCM711C into an assigned slot of the main Series 90-70 rack, ensuring the rear connector fully mates with the backplane bus. Tighten the module retaining screws to secure mechanical grounding to the rack chassis.
Connect the dual multimode ST fiber cables between the primary and secondary RCM modules, cross-connecting transmit and receive optical ports. Maintain a minimum fiber bend radius of 3.0 inches inside wire ducts to prevent signal attenuation. Ensure all protective dust caps remain installed on unused optical transceivers to prevent dust accumulation on optical surfaces.
