MCGS (Monitor and Control Generated System) is a widely used human-machine interface (HMI) platform for industrial automation. Proper touch calibration of an MCGS HMI panel is essential to ensure accurate input, reliable operation, and operator safety. This essay explains why calibration matters, describes common causes of touch misalignment, outlines a practical calibration procedure, discusses verification and maintenance, and highlights best practices for minimizing touch-related issues in industrial environments.
In rare cases, you can force recalibration via MCGS script commands. Use the !SetCalibration() or !TouchCalibrate() function in a Macro or Run Script. However, this requires the HMI’s operating system to expose these proprietary API calls. Disclaimer: Use only with manufacturer documentation. mcgs hmi touch calibration
Ensure there is no electromagnetic interference nearby and check that the HMI is properly grounded. MCGS HMI Touch Calibration MCGS (Monitor and Control
if you want to keep your existing project (selecting "YES" may clear the internal program on some models). : Flip the DIP switch back to Power off the HMI completely
: Displayed during the initial boot progress bar where you must tap to enter settings. "The new calibration settings have been set"
In addition to manual triggers, the MCGS configuration software (MCGS embedded version) allows engineers to program a calibration button directly into the user interface. By utilizing the system function "CheckTouch()", developers can provide operators with the ability to recalibrate the screen during routine operation without restarting the hardware. This proactive approach is particularly useful in harsh industrial environments where temperature fluctuations or mechanical vibrations can cause the resistive touch layers to shift over time.
