System compatibility

IC600BF944L belongs to GE Fanuc Series Six PLC family. Compatible with Series Six rack, CPU, power supply and discrete I/O modules. Widely used in old manufacturing, power auxiliary and chemical legacy automation systems.

Function

IC600BF944L is I/O processor board manufactured by GE Fanuc for Series Six PLC. It performs cyclic scanning of rack digital input signals, updates PLC I/O image table, and sends output commands from CPU to output modules via backplane bus. It also executes board-level self-test to detect backplane communication failure or hardware fault. This board acts as the bridge between main CPU and local I/O modules.

Installation

Follow lockout/tagout safety procedure before installation. Fully cut off Series Six rack power. Insert IC600BF944L board into vacant rack slot and secure retainer. Inspect gold edge pins for oxidation and damage. Restore rack power, run system self-test and verify I/O scanning function.

Interface

Series Six backplane gold-edge connector, field I/O signal terminal connector, onboard test point terminals for GE Fanuc IC600BF944L.
