The GE IC640WMI610 is a Workstation Interface Board (WMI) designed for the GE Fanuc Series Six PLC system, enabling high-speed communication between an industrial workstation computer and the PLC backplane.
It is a legacy ISA-bus communication interface card used in older automation architectures where a dedicated workstation needed direct access to PLC data for real-time monitoring, programming, and control. Today, it is considered an obsolete but mission-critical spare part for maintaining legacy GE Series Six installations.
Technical Specifications
The IC640WMI610 is engineered as a high-speed parallel communication interface between workstation and PLC CPU.
