Description
The IC697BEM731 is a Genius Bus Controller used in the IC66 PLC system, designed to operate within an IC697 rack as a single-slot module. It supports a Genius I/O bus structure that allows up to 30 devices per channel, enabling distributed I/O communication in industrial automation environments.

The module operates with a 5.0 V DC supply and draws 1.3 A backplane current. It features one Bus Controller channel and one Hand-Held Terminal port, supporting configuration, diagnostics, and local maintenance access. The bus communication uses defined baud rates of 153.5 Kbaud, 76.8 Kbaud, or 38.4 Kbaud depending on system configuration.

The IC697BEM731F is an early revision of the IC697BEM731, mainly optimized for improved stability in industrial electromagnetic environments while keeping the same electrical and functional design as IC697BEM731. The IC697BEM731U builds on IC697BEM731 with upgraded internal components that enhance power handling and interference resistance, offering more stable operation in modern control environments. The IC697BEM731V represents a further refined revision of IC697BEM731, featuring additional hardware hardening for improved long-term reliability in harsh industrial applications.

The IC697BEM731 performs asynchronous scanning of IC66 I/O blocks, transferring process data between field devices and the PLC CPU each scan cycle. It also supports CPU-initiated communication requests and global data exchange functions across the Genius bus network.

Fault information detected by IC697BEM731 is processed through the PLC Alarm Processor, which timestamps and queues diagnostic events for system monitoring. This ensures structured fault handling and improves system visibility during operation.

Across IC697BEM731 and its revisions, the module supports peer-to-peer communication between PLCs, PCIMs, and other IC66 devices via the Genius LAN. It enables global data transfer, datagram messaging, and redundant system configurations involving blocks, cables, and CPUs for expanded industrial network functionality.
