Figure 1: Technician adjusting connections at wiring closet

Connecting sensors and actuators to a process controller at the wiring cabinet is still a manually intensive and sometimes frustrating task. For example, if a process modification means a valve being driven by a Digital Output (DO) voltage must be changed to one using a 4-20mA Analog Output (AO) current, a technician mu
