Description
Product Description
The IC697CMM711 is a dedicated communications coprocessor designed for the GE Fanuc Series 90-70 PLC platform. It offloads communication tasks from the main CPU, enabling efficient data exchange between controllers, operator interfaces, and third-party devices.
Equipped with its own onboard processor, this module independently manages serial communications, improving overall system responsiveness. It supports multiple industrial protocols and allows concurrent communication through two configurable serial ports, making it suitable for complex automation networks.

Core Functional Features
The IC697CMM711 module enables reliable serial communication across heterogeneous systems. Its dual-port architecture allows simultaneous connections to multiple devices, while protocol flexibility ensures compatibility with both GE-native and third-party equipment.
The onboard microprocessor handles communication independently, reducing CPU load and improving scan performance in large-scale control systems. LED diagnostics provide quick status monitoring for troubleshooting and maintenance.
Application Scenarios
This module is typically implemented in systems requiring structured data exchange and integration across multiple devices, including:
-
PLC-to-PLC communication within distributed control architectures
-
Interface with HMIs, SCADA systems, or industrial PCs
-
Integration of Modbus RTU field devices such as drives and meters
-
Legacy system expansion where serial communication remains essential
FAQ
Q: Can both serial ports operate at the same time?
A: Yes, the module supports simultaneous communication on both ports with independent configuration.
Q: Does the module support Modbus master mode?
A: No, Modbus RTU is supported in slave mode only.
Q: Is this module a replacement for Genius communication modules?
A: No, it is a serial communication coprocessor and does not provide Genius bus functionality.
Q: Does it require additional power or battery?
A: No external battery is needed; it draws power directly from the PLC backplane.
