GE Fanuc IC697BEM731 Bus Controller Module

Description

The GE Fanuc IC697BEM731 Bus Controller Module is a core component of the GE Fanuc Emerson Series 90-70 PLC system, designed exclusively for the Genius I/O handheld monitors IC660/IC661. Its primary function is to establish reliable communication between IC697 PLCs and Genius I/O devices, supporting connections to up to 30 devices and facilitating data transmission via token-passing protocol.

Equipped with a single-channel Genius I/O interface, the module uses asynchronous scanning and backplane communication to exchange data with the PLC. It can be configured via MS DOS or Windows programming software; shipped with no predefined bus address, it defaults to a baud rate of 153.6 kbps and bus address 31, which can be modified by downloading a valid configuration to the CPU. Communication distance varies by baud rate: 2000 feet at 153.6 kbps (standard), 3500 feet at 153.6 kbps (extended), 4500 feet at 76.8 kbps, and 7500 feet at 38.4 kbps, with all devices on the same bus requiring matching baud rates.

Key features include redundancy support for enhanced system reliability, integrated LAN communication for easy network integration, and a built-in alarm processor for real-time fault monitoring. It also offers 30 fault points per channel, IC660/IC661 I/O diagnostic capabilities, global communication support, a handheld monitoring port, and CPU soft configuration functionality to streamline system setup and operation.
