Mcgs Hmi Touch Calibration

For older MCGS units (pre-2018, such as the TPC7062K or TP1062Ti), the operating system does not run Windows CE or Linux. Instead, it runs an embedded proprietary RTOS. On these models, you cannot use OS software tools. You must use the hardware boot-time calibration.

You shouldn't need to calibrate an MCGS HMI monthly. If you are, address the root cause:

If the screen is completely unresponsive, you can force calibration via the development environment:

In MCGS configuration software, calibration can be initiated programmatically. The system provides built-in functions to trigger the calibration interface without navigating complex menus. mcgs hmi touch calibration

This is the primary method for 95% of MCGS units.

Step-by-step:

  • Keep holding until the screen flashes white or shows a crosshair (target) in the top-left corner.
  • Follow the crosshairs: Tap precisely in the center of each target as it moves (top-left → top-right → bottom-left → bottom-right → center).
  • After the last tap, the screen will either:
  • Result: Touch alignment restored.

    Q1: Does MCGS HMI calibration affect my project logic? No. Calibration only changes how touch coordinates are mapped to the screen. It does not alter your tags, alarms, recipes, or ladder logic.

    Q2: How long does calibration take? Less than 30 seconds from start to finish.

    Q3: Can I calibrate without a stylus? For resistive screens, it is not recommended. For capacitive screens, your finger is fine. For older MCGS units (pre-2018, such as the

    Q4: My MCGS screen reboots during calibration. What’s wrong? This indicates a power supply issue. The calibration routine may draw extra current. Check your 24V DC power supply for voltage drop.

    Q5: Is there a difference between "touch calibration" and "screen alignment" in MCGS? No. The terms are used interchangeably.

    Q6: Can I perform remote calibration over Ethernet? Not directly. However, you can use remote desktop software (like VNC) if your MCGS HMI supports it. The remote mouse movements will simulate touches, but you will need someone on-site to press the physical targets. Keep holding until the screen flashes white or


    When designing the project in MCGS Embedded (McgsPro or older Mcgs7.7):

    Human fingers are too blunt for precise calibration of resistive MCGS panels. Always use a stylus. The official MCGS stylus (plastic tip, ~2mm diameter) is ideal.
