Prior to PLCs, many of these control tasks were solved with

contactor or relay controls. This is often referred to as hardwired

control. Circuit diagrams had to be designed, electrical

components specified and installed, and wiring lists created.

Electricians would then wire the components necessary to

perform a specific task. If an error was made the wires had

to be reconnected correctly. A change in function or system

expansion required extensive component changes and rewiring.
