Available. The GE Fanuc IC697RCM711C is a Redundancy Communication Module designed for the GE Fanuc 90-70 series Programmable Logic Controllers (PLCs). This module facilitates seamless communication between an active PLC and its backup unit, ensuring system reliability and minimizing downtime in critical industrial applications. The IC697RCM711C is a single-slot module that fits between slots 2 and 9 in the PLC rack. It features five status LEDs—Board OK, Local Ready, Local Active, Remote Ready, and Remote Active—to provide real-time system diagnostics. The module operates with a current requirement of 0.7 amps and is configured using MS-DOS software. It supports high-speed parallel bus interfaces and is compatible with Hot Standby CPU Redundancy systems. Installation requires powering down the rack before inserting the module and connecting the appropriate cables. Once installed, the system can be powered back on, and the module will synchronize the active and backup units, allowing for maintenance without system downtime. For detailed installation and configuration instructions, refer to the Hot Standby CPU Redundancy User’s Guide or the Enhanced User’s Guide.
