Most older or budget-friendly MCGS models use (pressure-sensitive). Unlike your phone’s capacitive screen, these rely on precise voltage alignment between the LCD and the touch film.
Ensure there is no electromagnetic interference nearby and check that the HMI is properly grounded.
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
Most modern MCGS TPC series devices follow a built-in startup routine to access calibration settings. 1. Entering the Boot Setup Interface
: Always calibrate after a screen replacement or significant firmware update. Step-by-Step MCGS HMI Calibration Process In rare cases, you can force recalibration via
To understand calibration, one must distinguish between two coordinate systems:
If the touch screen is completely unresponsive or the drift is too severe to navigate menus, most MCGS models allow for a "forced" calibration. This is often achieved by holding a finger on the screen while powering the device on, or by toggling specific DIP switches on the back of the unit. This bypasses the project software and goes directly to the firmware’s calibration tool. The Calibration Process Disclaimer: Use only with manufacturer documentation
, the system will automatically launch the touch calibration program. Manual Entry
