HMI User Interface
🔹 Introduction
HMI (Human Machine Interface) is one of the main components of industrial automation that acts as a link between the operator and machinery or control systems.
These displays allow operators to view process data, apply desired adjustments, and monitor system performance in real-time.
HMIs play a key role in industries such as oil and gas, petrochemical, automotive, pharmaceuticals, food, and packaging and are considered a modern replacement for old control panels.
🔹 Features and Benefits
-
Graphical display of industrial processes and equipment
-
Increased accuracy and speed in monitoring and control
-
Direct connection capability to PLC, DCS, and industrial networks
-
Reduction of human errors and simplification of operator tasks
-
Support for various communication protocols (Modbus, Profinet, EtherNet/IP, etc.)
🔹 Frequently Asked Questions (FAQ)
What is the purpose of HMI?
