Calibrating an MCGS (Modern Computer Graphic Software) HMI, such as the TPC series, is a straightforward process typically performed during the boot sequence to ensure touch accuracy aligns with the visual display. Calibration Procedure
What happens if you accidentally calibrate to a stuck pixel or a damaged spot? The HMI enters a boot loop or boots to a blank screen. mcgs hmi touch calibration
Access Console: Navigate to the System Settings or Setup Menu from your home screen. Calibrating an MCGS (Modern Computer Graphic Software) HMI,
| Type | Calibration Need | Method | |------|----------------|--------| | Resistive (older MCGS) | Frequent (drift over time) | Standard crosshair method | | Capacitive (newer TPC series) | Rare (factory calibrated) | Usually none; if needed, use boot menu | Access Console : Navigate to the System Settings
In MCGS configuration software, calibration can be initiated programmatically. The system provides built-in functions to trigger the calibration interface without navigating complex menus.
If you can still navigate the interface, use the built-in system settings: Locate the System Settings Maintenance button on your HMI project (if programmed). Navigate to the Touch Calibration Click "Start Calibration." Use a stylus or a fine-tipped object for better accuracy. center of the crosshairs as they appear in the corners and the center of the screen. Method 3: Using MCGS Configuration Software
The latest MCGS models (Tpc7032Gi, Tpc1531Gi) run a Linux kernel. Calibration is handled by the tslib library. There is no visual calibration button in the user runtime.
