Programmable Logic Controller, or PLC (no HMI included), is a method of electrical control logic where a central processing unit reads and evaluates system parameters. PLC can compare these inputs to current and historical values (sequential logic) and provide single or multiple outputs based on a programmed solution. The major differences between relay and PLC logic are combinational versus sequential logic and the speed under which similar tasking can be accomplished.
