Description
The GE IC697CMM741RR is a redundant Ethernet controller module designed for GE Fanuc Series 90-70 PLC systems, offering high-reliability industrial communication with dual-channel redundancy. Based on the non-redundant IC697CMM741, this module extends connectivity for mission-critical applications requiring continuous data flow. Below is a detailed analysis of its features, specifications, and applications:
Product Overview
The IC697CMM741RR builds on the single-port IC697CMM741 by adding a second independent Ethernet channel, enabling automatic failover if one port fails. It supports IEEE 802.3 CSMA/CD at 10 Mbps via a 15-pin AUI port, compatible with media types like 10Base5 (thick coaxial), 10Base2 (thin coaxial), and 10BaseT (twisted pair) . The module’s 80C186 microprocessor handles protocol processing for both channels, while soft-switch configuration via GE’s Proficy software eliminates physical jumpers. Key enhancements include:
- Dual-channel redundancy: Ensures uninterrupted communication in 24/7 operations.
- Hot-swappable design: Allows online replacement to minimize downtime.
- Wide temperature tolerance: Operates from -20°C to +60°C, suitable for harsh industrial environments .

Key Features and Advantages
-
Dual Redundant Communication Paths:
The IC697CMM741RR provides two independent Ethernet channels, ensuring seamless data transfer even if one port experiences a fault. This is critical for applications like pharmaceutical manufacturing, where continuous operation is mandatory. -
Flexible Media Support:
Supports multiple Ethernet media types via external transceivers, making it suitable for retrofitting legacy systems. For example, it can connect to a 10BaseT network using a twisted-pair transceiver without replacing existing cabling . -
Hot-Swap Capability:
Field-replaceable design allows online module replacement, reducing mean time to repair (MTTR) by up to 50% compared to non-redundant models. This is essential for industries like food processing, where downtime costs are high. -
Hybrid Network Integration:
While optimized for basic Ethernet communication, the module can be paired with Modbus TCP/IP converters to bridge legacy systems with modern SCADA platforms, extending the lifespan of existing investments. -
Space-Efficient Design:
Single-slot form factor fits seamlessly into Series 90-70 racks, optimizing cabinet space in distributed control systems (DCS).
Application Areas
The IC697CMM741RR excels in high-reliability scenarios requiring redundant Ethernet connectivity:
- Process Control: Managing distributed control systems (DCS) in chemical plants, where redundant communication ensures precise regulation of reactors and pumps.
- Automotive Manufacturing: Coordinating robotic welding cells and conveyor systems across multiple Ethernet networks in assembly plants.
- Power Generation: Enabling redundant communication between turbine control systems and grid synchronization modules to maintain stable energy output.
- HVAC Systems: Integrating building automation systems with PLC-controlled heating/cooling units in critical environments like data centers.
Its compatibility with GE’s Genius I/O and GMR (Genius Modular Redundancy) systems makes the IC697CMM741RR a versatile choice for retrofitting aging infrastructure. For instance, it can integrate legacy sensors into modern redundant PLC systems without replacing software.
