HMI
HMI typically stands for Human-Machine Interface. It refers to the point of interaction between a human (operator or user) and a machine (such as a computer, industrial equipment, or a device). HMIs are designed to facilitate efficient communication and control, often through graphical interfaces or touchscreens, enabling users to monitor processes, input commands, and receive feedback from the system they are interacting with. These interfaces vary widely in complexity and design depending on the application and the specific needs of the users and systems involved.
PLC
PLC stands for Programmable Logic Controller. It’s a specialized computer used in industrial automation and control systems to automate processes. PLCs are designed to reliably control machinery and processes, based on inputs from sensors and switches. They execute control logic stored in their memory to make decisions and operate outputs like motors, valves, and actuators. PLCs are essential in manufacturing, automotive, and other industries where precise and reliable control of processes is crucial.
