GE Fanuc IC697CMM711 Communications Coprocessor Module

Product Overview

The GE Fanuc IC697CMM711 is a high-performance Communications Coprocessor module specifically designed for the Series 90-70 PLC rack. By handling intensive communication protocols independently, it preserves the main CPU's processing power for critical logic execution. This module is a single-slot solution that provides robust connectivity for industrial networks, featuring a 0.9 kg (approx. 1.98 lbs) build quality optimized for long-term stability in factory settings.

Core Technical Capabilities

The IC697CMM711 provides versatile protocol support, including CCM, RTU (Modbus), SNP, and SNPx, making it an essential bridge for multi-vendor environments and HMI interfacing. It is equipped with two serial ports that support high-speed data transmission at rates up to 115.2 kbps. Operating on a 24 VDC power supply with a current requirement of 0.7 amps, the module utilizes natural convection for cooling, ensuring reliable performance within an operating temperature range of 0°C to 60°C.

Physical Characteristics & Installation

The module's physical design is tailored for standard Series 90-70 rack integration, with dimensions of 283mm x 483mm x 190mm (11.15 x 19.00 x 7.5 inches). At a weight of 0.9 kg, it is securely housed to withstand industrial vibrations. The IC697CMM711 is designed for easy installation into any available full-height slot on the 90-70 backplane, providing immediate expansion of the PLC's networking capabilities without requiring external power converters.

Technical Specifications

Application Benefits

By implementing the IC697CMM711, system integrators can significantly enhance the data throughput of their Series 90-70 racks. It is particularly effective in SCADA applications and distributed control systems where multiple devices must communicate simultaneously without lagging. The module’s 5% to 95% non-condensing humidity range and robust storage ratings (down to -40°C) ensure it remains a reliable choice for diverse global installations, from offshore platforms to high-heat manufacturing plants.

Technical FAQs

Q1: What is the primary function of the coprocessor module?
A1: It manages serial communication protocols independently, allowing the main PLC CPU to focus entirely on logic and I/O scanning, which improves overall system response time.

Q2: Can I use both serial ports simultaneously?
A2: Yes, the two serial ports are designed for independent operation, allowing you to run different protocols or connect to different devices on each port.

Q3: Does this module support Modbus communication?
A3: Yes, through its support for the RTU protocol, the IC697CMM711 can be configured to communicate with Modbus RTU compliant devices.
