Explanation: The main components of an industrial automation system are the Programmable Logic Controller (PLC), Human Machine Interface (HMI), and the control system. The PLC is the “brain” of the automation system, responsible for executing the control program. The HMI is the interface between the control system and the operator, providing a way for the operator to interact with the automation system. The control system is responsible for coordinating the actions of the PLC and the HMI, and for monitoring and controlling the industrial process. Sensors and actuators are also an important part of industrial automation system, which are used to gather data from the process and control the process respectively.
