What Does HMI Stand For?

HMI stands for Human Machine Interface. In industrial automation, an HMI is the touchscreen panel that lets a machine operator see what a machine is doing and control it.

How Does an HMI Work?

An HMI connects to a PLC (Programmable Logic Controller) via an industrial communication protocol such as Modbus RTU, Modbus TCP, EtherNet/IP, or PROFIBUS. The PLC controls the physical machine; the HMI reads the PLC's data registers and displays them visually on screen.

Types of Industrial HMI Panels

• Push-button panels, simple switches and indicator lights, no screen
• Text-based HMIs, alphanumeric display, low cost
• Touchscreen HMI panels, most common today, 4.3" to 21.5"
• Panel PCs running HMI software, full Windows PC with HMI runtime
• Web-based / cloud HMI, browser-based SCADA dashboards

Key Features to Look For in an HMI

• Screen size and resolution for your operator's workspace
• IP65 or IP67 rating for wash-down or dusty environments
• PLC protocol compatibility (Modbus, EtherNet/IP, etc.)
• Operating temperature range for your environment
• MTBF (Mean Time Between Failures) for reliability
