Description

The General Electric IC697BEM731 is a high-performance Genius Bus Controller (GBC) module designed for the Series 90-70 PLC platform. This single-slot module serves as the communication interface between the PLC CPU and the Genius I/O network, enabling efficient data exchange and system-wide diagnostics. It supports up to 30 I/O devices (drops) per channel and facilitates advanced features such as global data broadcasting, peer-to-peer communication, and redundant system configurations.

Features

  • Supports up to 30 Genius I/O drops per channel.
  • Integrated support for IC660/IC661 I/O diagnostics.
  • Enables redundant CPU, block, and cable configurations for high-availability applications.
  • Features a dedicated Hand-Held Terminal port for local diagnostics and maintenance.
  • Supports global communications and peer-to-peer information transfer between PLCs and host computers.
  • Soft configuration via programming software, with settings stored in the CPU for enhanced security.
  • Integrated with the IC697 PLC Alarm Processor function for automated fault time-stamping and queuing.

Installation Guidelines

  • Ensure the PLC rack is powered down before inserting or removing the IC697BEM731 module to prevent electrical damage.
  • The module occupies a single slot in the IC697 backplane; ensure it is fully seated and the locking levers are engaged.
  • Use shielded twisted-pair cabling for the Genius bus to minimize EMI interference.
  • Proper bus termination is critical: install 75 or 150 Ohm termination resistors at both physical ends of the electrical bus cable.
  • Maintain proper cable routing away from high-voltage lines or high-EMI sources to ensure signal integrity.
  • Configuration must be performed via compatible programming software; the module receives its operational parameters from the CPU upon power-up.

FAQ

What is the IC697BEM731?

The GE Fanuc IC697BEM731 is a single-slot Genius Bus Controller module for the Series 90-70 PLC system, supporting up to 30 I/O devices (drops) per channel, Global Data broadcasting, and redundancy.

What is the cable length supported by the IC697BEM731?

Transmission distances range from 2000 feet at 153.6 Kbaud to 7500 feet at 38.4 Kbaud.

What does a flashing COMM OK LED indicate?

It suggests the bus controller is active but experiencing intermittent communication errors, often caused by loose terminal connections, poor cable shielding, or missing termination resistors.
