What is the role of PLC in automation?
PLC plays most important role in automation. PLCs carry out all monitoring and controlling operations.
PLC processes logic via CPU and memory, senses input through I/P modules, and outputs through output modules.
Within a very short moment, it conducts accurate activities. That is one of the factors for the widespread use of PLC in the industrial sector today.

What is the role of PLC in automation?
PLCs are used to monitor, communicate with, and manage automated tasks such as assembly lines, machine operations, or robotic devices. The three main categories of a PLC’s functions are inputs, outputs, and the CPU. PLCs monitor inputs that machines and other devices are connected to in order to collect data from the factory floor.
