The GE IC697BEM713 is a high-speed Bus Controller Module (GBC) designed for the GE Fanuc Series 90-70 PLC architecture. It functions as the primary interface between the main CPU and a network of remote Genius I/O blocks, providing a reliable and deterministic communication path for distributed control. The module supports a single Genius bus string and can manage up to 30 external devices. It handles all bus arbitration and error checking internally, significantly reducing the overhead on the main processor. Its diagnostic LEDs and robust integration with the MS-DOS or Windows-based programming software make it a cornerstone for maintaining legacy Series 90-70 automated systems.

Model Comparisons
The IC697BEM713 is often compared to the IC697BEM711, which is an older version with more limited diagnostic reporting and slower internal bus synchronization. While both support the Genius protocol, the BEM713 offers improved noise immunity and is better suited for larger, high-density I/O configurations. Compared to the IC697BEM731 (FIP Bus Controller), the BEM713 is strictly dedicated to the Genius network architecture and cannot be used on WorldFIP networks. Unlike newer PACSystems RX3i modules like the IC695PBM300, the BEM713 requires the specialized 90-70 VME-based backplane and is not compatible with modern PCI-based racks.
