Allen-Bradley 1747OC-EEDBA Open Controller CPU

Allen-Bradley 1747OC-EEDBA Open Controller CPU is a PC-based Open Controller CPU in the 1747-OC family, designed to integrate with SLC 500-era I/O in an open-control architecture. It was manufactured by Allen-Bradley but built by Online Development Inc. (OLDI) in Knoxville, Tennessee, reflecting its status as an early open-architecture controller. Unlike standard Rockwell RSLogix/RSLinx-based programmers, the 1747-OC does not rely on Rockwell's traditional software, and it uses alternative development tools to load and manage programs. The Open Controller CPU module can operate with 1746 I/O in its configurations, and some configurations are packaged with Controlware software bundles for PC-based control workflows.
