Use a Stylus: For maximum precision, use a plastic stylus rather than a finger.
No. Calibration only changes how touch coordinates are mapped to the screen. It does not alter your tags, alarms, recipes, or ladder logic.
Regardless of how you triggered the calibration interface, the execution process follows a standard 4-point or 5-point touch alignment procedure:
If you can still interact with the screen reasonably well, you can access the calibration tool through the MCGS system menu. For Linux/WinCE-based MCGS Models:
Once in the basic system startup menu, click on Control Panel or System Settings . mcgs hmi touch calibration
Look for an option labeled Stylus , Touch Screen , or Calibration .
If your screen is completely unresponsive or the drift is too severe to navigate the menus, you can force the calibration screen directly during the boot sequence. Shut down the power supply to the MCGS HMI.
Regular maintenance, proper cleaning, and safe operating habits will ensure your MCGS HMI remains a highly reliable and responsive tool on your factory floor. If you want to troubleshoot a specific issue, let me know: What of MCGS HMI are you using? Is the screen completely unresponsive , or just misaligned ? Are you receiving any error messages on the display? Share public link
If the touch screen completely stopped working after a software update, a corrupted firmware or driver may be to blame. Reinstalling the MCGS project file or updating the HMI firmware can resolve this. Use a Stylus: For maximum precision, use a
Code: !CalibrateTouch() (Note: Exact syntax can vary slightly between MCGS basic and MCGS Pro versions; check your software's system function library under "Screen/Touch control").
Power on the TPC. As the device boots, you will see a loading progress bar. You need to catch the system before it loads the user application.
Flashing a new runtime environment or updating MCGS Embedded Software can sometimes reset factory coordinate maps. Method 1: Hardware-Based Calibration (Before Boot)
Last updated: 2025. This guide applies to MCGS Embedded, MCGS Pro, and MCGS Utility series HMIs running Windows CE 6.0/7.0 and newer Linux-based models. It does not alter your tags, alarms, recipes,
If you have ever pressed a "Start" button on your MCGS panel only for the machine to hit "Emergency Stop," you are experiencing a calibration error. This is where becomes not just a maintenance task, but a critical safety procedure.
MCGS employs a "Two-Stage" calibration architecture.
If your HMI is located in a harsh area (e.g., a machine shop with flying debris, or a food processing plant where water is sprayed), consider installing a protective industrial . These protectors shield the screen from scratches and direct impact while maintaining touch sensitivity. 3. Use Proper Input Tools
