Product Role & System Fit
The IC697BEM731U functions as the central bus controller for a Genius I/O network — a proprietary token-passing communication scheme developed by GE for distributed automation segments. Its role is both coordinator and translator: it orchestrates bus communication among remote devices and transfers consolidated I/O data to the main CPU over the PLC’s backplane.
Installed in a single handheld monitor slot of a Series 90-70 PLC rack, this controller does not consume CPU processing cycles but works with the rack’s communication architecture to relay data efficiently. This design promotes modular growth, since additional controllers, when present, can manage other bus segments without interfering with the core logic execution.
Compatibility is broad within the Series 90-70 ecosystem. Whether interfacing with IC660 or IC661 classes of Genius blocks, or integrating remote I/O scanners for larger machine centers, the IC697BEM731U supports both directed communications initiated by the CPU and global data exchanges for inter-controller information flow.
From a system architecture perspective, deploying this module early in the design phase helps engineers allocate rack slots, plan bus topologies, and establish diagnostic expectations. Feeding data back to human-machine interfaces, logging systems, and SCADA packages becomes more predictable when a single controller governs a bus segment with clear addressing and configuration.
