Human-Machine Interface Panel
Industrial operator-panel station for process visualization, equipment control, alarms, trends, recipes, and other HMI functions.
An HMI panel presents machine or process status to the operator and allows commands, setpoints, and process data to be entered. It may provide a touchscreen, function keys, encoder, or other operator controls.
Hardware parameters include display diagonal, resolution and technology, brightness, touch technology, memory, CPU, Ethernet/serial/USB interfaces, and mounting method. Runtime characteristics include limits on screens, tags, alarms, trends, recipes, scripts, controller connections, and data archiving.
Advanced panels may support web HMI, OPC UA, MQTT, VPN, users and roles, audit trails, electronic signatures, remote access, and encryption. Front IP rating, temperature range, mechanical resistance, and engineering-software compatibility are also important.
This subcategory includes industrial HMI operator panels with touchscreens and/or keys, web-HMI devices, and local visualization terminals for automation systems.
