The GE IC697BEM721 is a Series 90-70 I/O Link Interface Module designed for high-speed serial communication between GE Fanuc PLC systems and external I/O or CNC devices. It enables a master PLC to exchange real-time data with multiple slave devices through the proprietary GE Fanuc I/O Link network.
This module is widely used in distributed automation systems where fast deterministic communication, CNC integration, and multi-device coordination are required. It plays a critical role in extending PLC control beyond local racks into broader industrial networks.
