GE Fanuc IC697RCM711 Redundancy Communications Module

Product Overview

The GE Fanuc IC697RCM711 is a single-slot Redundancy Communications Module engineered for high-availability Series 90-70 PLC systems. Weighing approximately 0.68 kg (1.5 lbs), this hardware module establishes a dedicated communication link between primary and backup controller racks to sync data and manage seamless hot-standby switchovers. Operating on a 5 VDC backplane voltage, it features five active LED indicators for real-time status monitoring, ensuring high system uptime in critical process control applications.

Core Technical Advantages

• High-Availability Dual Rack Sync: Controls real-time redundancy handshakes between primary and backup processors to eliminate system downtime during a CPU fault.
• Efficient Backplane Power Draw: Consumes a low 0.7 Amps at 5 VDC, leaving plenty of power headroom for high-density I/O configurations on the same rack.
• Clear Visual Diagnostics: Features 5 built-in LED indicators on the front panel to provide immediate status tracking and fault isolation for local engineering teams.

Technical Specifications

Installation & Engineering Guide

• Slot Insertion: Align the 0.68 kg card with a single open slot inside the IC697 PLC rack. Press firmly until the module seats cleanly into the backplane, and tighten the retaining screws to guarantee a reliable grounding path.
• Serial Connections: Wire the master interface via the 9-pin D-sub serial connector. Ensure your point-to-point shielding remains intact across the 500-meter maximum length to maintain a clean 9600 bps link without data loss.
• Environmental Maintenance: Ensure cabinet cooling fans provide adequate airflow around the IP20 housing to keep temperatures below 60 °C (140 °F), avoiding performance degradation or communication drops.

Technical FAQs

Q1: How many serial ports are actively used on the IC697RCM711 module?
A1: The module has 2 serial ports, but only 1 port is utilized for the active redundancy data link via the standard 9-pin D-sub connector.

Q2: What do the 5 integrated LED indicators on the faceplate display?
A2: They display critical hardware diagnostics, monitoring parameters like backplane power stability, port communication status, and active rack role allocation.

Q3: Can this hardware module withstand freezing warehouse environments during storage?
A3: Yes. While its operational limit starts at 0 °C, the unit is safely rated to survive unpowered warehouse storage temperatures as low as -40 °C (-40 °F).
