A Complete Guide to HMI (Human Machine Interface) in Industrial Automation
- 1. A Complete Guide to HMI (Human Machine Interface) in Industrial Automation What is HMI? HMI (Human Machine Interface) is a user interface or dashboard that connects a person to a machine, system, or device. In industrial settings, it allows operators to monitor and control processes through touchscreens, displays, or panels. How Does an HMI Work? HMI devices gather real-time data from programmable logic controllers (PLCs) or sensors. The HMI displays this data visually so users can make decisions, adjust settings, and interact with machines effectively. It acts as a translator between operator commands and machine actions. Component Function Display Screen Visual interface showing data, alarms, and status Input Controls Buttons or touch inputs for user interaction Communication Ports Connects to PLCs and other systems Software Manages logic, visualization, and configuration
