Human Machine Interface
 HMI stands for human machine interface. This is the interface between the operator and the controller, allowing a person to operate and interact with a machine or system. The HMI is the controller operating panel, which consists of a numeric keypad and an LCD screen that displays text, visuals and other information. The keypad is used to input data into the application, such as Timer values.
The PLC's display screen can show operator messages, variable information from the program and system information; HMI messages are created in the Display Editor, and variable information fields are created in the Variable Editor.
At E-Motion Supply, we carry a wide selection of HMIs, interfaces and displays, including the Parker PowerStation, Delta HMI and Beckhoff. Our touchscreen displays are designed to handle the rigorous loads of engineering, life science, aerospace and more. Portable, lightweight and easy to clean, these interfaces display data accurately and quickly.
