MeloAuto-Trusted PLC & DCS Parts Supplier
The IC697BEM731W functions as a Genius bus controller for the Series 90-70 PLC system. This module manages communication between the CPU and remote Genius I/O blocks. It scans all connected devices on the bus at high speed. Therefore, this controller enables distributed I/O architectures across large factory floors.
Technical Specifications
We engineered this bus controller for reliable operation in industrial networks. Its single-slot form factor fits directly into a standard 90-70 rack. Moreover, the module supports both Series 90-70 and third-party Genius devices.

Bus Communication and Scanning
The IC697BEM731W manages all data transfers on the Genius bus network. This module scans each connected block sequentially during each bus scan cycle. It automatically detects new devices added to the network. Consequently, you can expand your I/O system without manual configuration changes.
Global Data and Peer Communication
This bus controller supports global data exchange between multiple PLCs simultaneously. Each node on the network can share data with every other node directly. The module handles both input data and output data with equal efficiency. As a result, you can build coordinated multi-processor control systems easily.
Diagnostic Capabilities and Fault Handling
The IC697BEM731W provides comprehensive diagnostic data for every bus device. This module reports communication errors, cable breaks, and device failures immediately. It supports auto-configuration of replacement devices on the network. Therefore, maintenance personnel can replace failed blocks without any programming tools.
Energy Storage and Data Retention
This bus controller does not contain any battery or energy storage components. It relies entirely on the backplane for continuous operating power. All configuration data resides in the main CPU’s memory, not on this module. Hence, replacing this module does not require reloading any bus parameters.
Installation and Bus Wiring
Mount the IC697BEM731W into any Series 90-70 rack slot. Connect the Genius bus cable to the module’s front-panel connector. Use twisted shielded pair cable for all bus wiring installations. Terminate both ends of the bus cable with 100-ohm resistors for proper signal quality.
