GE IC697BEM731/734 Bus Expansion Modules
Functions
The IC66* Bus Controller (GBC/NBC) is available as a single channel controller. It occupies a single IC66* PLC slot. The bus controller is configured by the MSDOS or Windows programming software configurator function. IC66* Input/Output blocks are scanned asynchronously by the bus controller and I/O data is transferred to the CPU once per scan over the backplane of the IC697 PLC rack.
The bus controller also supports directed communications initiated by a PLC CPU Communication Service Request. In addition, it may be configured to perform global communications. Faults reported by the bus controller are managed by the PLC Alarm Processor Function which time stamps and queues faults in a table.

Installation
Installation should not be attempted without referring to the applicable PLC Installation Manual.
Make sure rack power is off.
Install in rack.
Turn on power.
The module should power up and blink the top LED for about 5 seconds. When the diagnostics have completed successfully the top LED stays. The middle LED is turned ON when a valid configuration for the module has been received from the CPU, and the IC66* I/O bus operation has been verified. The bottom LED is OFF under all conditions.
Removing a Module
The instructions below should be followed when re-moving a module from its slot in a rack.
Grasp the board firmly at the top and bottom of the board cover with your thumbs on the front of the cover and your fingers on the plastic clips on the back of the cover.
Squeeze the rack clips on the back of the cover with your fingers to disengage the clip from the rack rail and pull the board firmly to remove it from the backplane connector.
Slide the board along the card guide and remove it from the rack.
