if you want to keep your existing project (selecting "YES" may clear the internal program on some models). : Flip the DIP switch back to
If the screen registers touches when nobody is touching it, check if there is moisture, oil, or a buildup of debris on the edges of the screen bezel. Clean the edges thoroughly.
This is the standard approach used for modern embedded TPC series models like the TPC7062 series. External Interface Product Installation
: The system will enter a boot setup interface. Wait approximately 30 seconds without further action, and the system will automatically launch the touch screen calibration utility. Perform Calibration : A crosshair cursor will appear on the screen.
Conclusion Accurate touch calibration is a small but vital part of HMI reliability and operator effectiveness in MCGS-based control systems. Regular calibration, thorough verification, sensible environmental and hardware practices, and prompt troubleshooting of anomalies keep operator inputs precise and processes safe. Documenting calibration events and adopting simple preventive measures will reduce downtime and extend the usable life of HMI panels.
Before turning screws or tapping screens, understand the root cause. The MCGS uses a . Unlike a smartphone (capacitive), resistive screens rely on physical pressure. Two conductive layers touch when you press the screen, creating a voltage change.
The HMI is a cornerstone of industrial automation, known for its reliability and user-friendly interface. However, over time or after a system update, you might find that the touch response becomes inaccurate—where you tap a button, but the system registers the touch elsewhere.
Look at the back of the HMI shell. Locate the small dip switches or the physical "Reset/Boot" button. Step 3: Power Up in Calibration Mode
: If you enter the startup properties window and do nothing for 30 seconds
Navigate to the underlying operating system desktop or system menu (usually accessible by clicking a hidden corner button during the first 3 seconds of boot-up).
: Tap anywhere on the screen to exit the utility and return to the standard operating interface. Troubleshooting & Tips
If you are still experiencing issues after following this guide, consult the official for your specific model or reach out to Kunlun Tongda’s technical support team. Happy calibrating!
Modern MCGS devices (TPC7032Kt, TPC1071Gi, TPC1262Hi) run Windows CE 6.0 or newer. These require calibration via the This is the most common scenario for users searching for "MCGS HMI touch calibration."
Over time, due to mechanical wear, temperature fluctuations, or software updates, an HMI touchscreen can lose its alignment. When an operator presses one button and the screen registers a click somewhere else, it compromises both productivity and safety.
If the screen loses calibration every time the machine power is cycled, the internal backup memory or RTC battery may be failing, or the firmware has become corrupted.
