GE Fanuc IC697BEM733 Series 90-70 Genius Remote I/O Scanner Module

The GE Fanuc IC697BEM733 is a Series 90-70 Remote I/O Scanner module that manages distributed I/O up to 7,500 feet away. It supports 1,024 discrete points and 64 analog words, featuring RS-422/485 connectivity and Hand-held Monitor support for advanced industrial automation and long-distance control.

System Architecture and Functionality

The IC697BEM733 acts as a high-capacity communication interface for the Series 90-70 PLC platform, enabling the integration of distributed I/O architectures. By utilizing this Remote I/O Scanner, engineers can deploy I/O stations at significant distances from the central rack, extending the physical reach of the control system up to 7,500 feet (2,275 meters). This module effectively manages the data exchange between the host controller and remote drops, ensuring that discrete and analog signals remain synchronized across the network.

This scanner handles a substantial data load, supporting a maximum of 1,024 discrete inputs and 1,024 discrete outputs. Furthermore, it accommodates up to 64 words of analog inputs and 64 words of analog outputs. Because the module supports sophisticated communication protocols, it also interfaces seamlessly with Programmable Coprocessor Modules (PCM) and Alphanumeric Display System (ADS) modules, broadening the functional scope of the remote station.

Advanced Connectivity and Integration

To facilitate comprehensive network management, the IC697BEM733 incorporates specialized ports for both communication and maintenance. It features a 15-pin RS-422/485 serial port for robust network interfacing and a dedicated 9-pin port designed specifically for the IC66* Hand-held Monitor (HHM). This HHM connection allows technicians to perform localized diagnostics and configuration without needing to access the central CPU.

In addition to its standard capabilities, the module supports redundant configurations. Through its dedicated bus terminals, the module ensures high system availability, which is essential for mission-critical industrial processes. The scanner effectively links up to 8 PLC racks in a typical remote drop configuration using bus transmitters and receivers to maintain signal integrity over long distances.
