PAC
PAC (Programmable Automation Controller) is a modern control system used in factories and industrial settings to manage machinery and automated processes. Think of it as a smart computer specifically designed for industrial use. It's more advanced than traditional PLCs (Programmable Logic Controllers) but easier to use than complex computer systems. PACs help control things like assembly lines, robotic systems, and manufacturing equipment. They're popular because they can handle multiple tasks at once, connect easily to other business systems, and are more flexible than older control systems.
