PLCs are used for automating the machinery control process. They can be used for both simple and complex operational requirements and scenarios. As a PLC can take a logic-based decision on its own, it automates many of the processes, lessens the burden for the operators, and also makes monitoring more convenient and efficient. Nowadays, PLCs are used for all kinds of industrial machines and scenarios. They may take the form of delicate sensors or the more rugged assembly line machinery and robots.
