Een industrieel HMI-paneel kiezen: de complete koopgids

Step 1: Choose the Right Screen Size

HMI screen size affects readability, operator ergonomics, and cost. Match screen size to viewing distance and complexity:

• 4.3", 5.6", compact machines, limited panel space, simple on/off control
• 7", 10", standard machine HMI; enough space for status, alarms, and basic trends
• 12", 15", multi-axis machines, production lines; full process overview
• 18", 21.5", large panel interfaces, SCADA-like overviews, multi-screen dashboards

Step 2: Confirm IP Rating for Your Environment

• IP65, front panel sealed against dust and water jets; standard for most manufacturing
• IP67, full immersion to 1m; needed for food processing and washdown areas
• IP69K, high-pressure steam cleaning; required in dairy, beverages, and meat processing

Step 3: Verify PLC Protocol Compatibility

The HMI must speak the same protocol as your PLC. Most Cermate HMI panels support 200+ PLC drivers including:

• Siemens S7 (MPI, Profibus, Ethernet)
• Allen-Bradley (DF1, EtherNet/IP)
• Mitsubishi (FX, QJ71)
• Delta, Fatek, Unitronics, Schneider, and more
• Modbus RTU and Modbus TCP (universal)

Step 4: Check Operating Temperature

Standard HMI panels operate 0°C, 50°C. If your environment is hotter (steel plant, outdoor summer) or colder (cold storage, outdoor winter), select a wide-temperature model rated to −20°C, 60°C or beyond.

Step 5: Consider Software and Connectivity

• Does it support data logging to USB or SD card?
• Can it send email alerts or SMS alarms?
• Does it support MQTT or cloud connectivity for IIoT?
• Is offline recipe management available?
