Programmable controllers, human-machine interface (HMI), and data acquisition are key elements of industrial automation.
Programmable controllers are industrial computers that control production processes in real-time. They are programmable and can be used to control a wide variety of machines and processes.
HMI is a device that allows operators to control and monitor production processes. It provides a graphical user interface to display real-time data and allows operators to control machines.
Data acquisition is the process of collecting data from sensors and other sources to monitor production processes. The collected data can be used to improve production processes and product quality.
