ControlEdge PLC and HC900 share rack/I/O hardware.

Then there was the one that shared ControlLogix hardware, but I do not remember what model that was.

Honeywell made a process controller CPU (not PLC controller CPU0, the C200, which Allen Bradley private labeled. Honeywell sold the C200 through their DCS channel (which is heavily gated with limited access).

The C200's functional replacement is the UOC controller, which shares the ControlEdge PLC/HC900 hardware platform.
