Touch Calibration — Mcgs Hmi

The calibration of a Kunlun Tongtai MCGS (Monitor and Control Generated System) HMI touch screen is a fundamental maintenance procedure essential for ensuring the precision and reliability of industrial control interfaces. As HMIs serve as the primary bridge between human operators and complex automated machinery, a misaligned touch sensor can lead to incorrect command inputs, operational delays, or significant safety hazards. The calibration process is designed to synchronize the physical touch coordinates on the screen’s surface with the underlying software’s graphical map.

  1. Exit the MCGS Runtime (if accessible via a system quit button in your project).
  2. Once on the WinCE desktop, go to Start → Settings → Control Panel.
  3. Double-click the Stylus icon.
  4. Go to the Calibration tab and tap Recalibrate.
  5. Follow the on-screen targets. After completion, tap OK and relaunch your MCGS project.

Calibrating your MCGS HMI—specifically the TPC series—ensures that the on-screen buttons respond accurately to your touch. This guide provides a detailed walkthrough of the calibration process, troubleshooting tips, and preventative maintenance. When to Perform Calibration mcgs hmi touch calibration

To ensure the highest accuracy, it is recommended to use a stylus or a blunt plastic tool rather than a finger. Since resistive screens react to pressure, using a fine point ensures the coordinates are captured exactly at the center of the target. After the final point is touched, the system usually asks for a confirmation click to save the new parameters to the internal memory. Conclusion Exit the MCGS Runtime (if accessible via a

Control Panel Settings: If you are using an MCGS HMI connected to a PC environment (like Windows 10/11), you may need to use the Windows Tablet PC Settings in the Control Panel to reset the touch input.
