Mcgs Hmi Touch Calibration

Troubleshooting steps may include:

A common failure mode in resistive touch screen HMIs is "drift," where the physical touch point does not align with the cursor position on the display. This drift arises from mechanical stress, temperature variations, or hardware aging. Touch calibration is the software process of realigning the coordinate mapping to restore input accuracy.

Some industrial cabinets use an external (trackpad/pointing device) connected via USB or PS/2. These require a different approach, as they do not have a physical screen.

: Ensure the display is free of dust or debris before starting, as external particles can interfere with the sensor.

Follow these steps to initiate and complete the touch calibration: Enter Boot Setup Cycle the power to the HMI (24V DC). During boot-up, a progress bar will appear with a
