Most MCGS HMIs run a Windows CE (or Embedded) operating system underneath the MCGS Runtime environment. Therefore, calibration is typically handled by the operating system’s touch driver, not the MCGS software itself.
This method works even if the touch is completely unresponsive.
Maintaining an MCGS HMI (Human-Machine Interface) is critical for industrial automation, where touch precision directly impacts operational safety and efficiency. Over time, factors like environmental wear, temperature shifts, or hardware aging can cause the touch registration to drift.
Calibrating your MCGS HMI—specifically the TPC series—ensures that the on-screen buttons respond accurately to your touch. This guide provides a detailed walkthrough of the calibration process, troubleshooting tips, and preventative maintenance. When to Perform Calibration
You should initiate a calibration procedure if you notice the following issues:
Misalignment: Tapping a button triggers the element next to it.
No Response: Specific areas of the screen fail to register touch.
Post-Repair: Always calibrate after a screen replacement or significant firmware update. Step-by-Step MCGS HMI Calibration Process
Most modern MCGS TPC series devices follow a built-in startup routine to access calibration settings. 1. Entering the Boot Setup Interface
Power Cycle: Turn off the power to the HMI and then turn it back on.
The "Start" Prompt: Watch the screen as it boots. When the "Start" prompt or progress bar appears, tap the screen anywhere using your finger or a stylus.
Waiting Period: Once you have tapped the screen, wait approximately 30 seconds. The system will automatically enter the touch screen calibration utility. 2. Executing the Calibration
Crosshair Alignment: A small crosshair cursor ("+") will appear on the screen.
Precise Tapping: Use a touch pen or stylus to tap exactly in the center of the crosshair. Firmly hold for a second and then lift. mcgs hmi touch calibration
Repeat: The cursor will move to several points (usually 4 or 5 positions). Repeat the tapping process for each new location.
Completion: Once all points are registered, a message will appear: "The new calibration settings have been set".
Exit: Tap the screen one last time anywhere to save the data and exit to the main operation interface. Alternative Calibration Methods
If the standard boot method is inaccessible, consider these alternatives:
External Mouse: If the touch is so poorly aligned that you cannot tap the initial prompt, connect a USB mouse to the HMI's USB port to navigate the system settings.
Software-Triggered: In some MCGS configuration environments, you can create a "hidden" service button in your project that calls the system function to launch calibration during runtime.

Introduction
MCGS (Machine Control and Gateway System) Human-Machine Interface (HMI) is a type of touch-sensitive screen used in industrial automation and control systems. To ensure accurate and reliable operation, it is essential to calibrate the touch screen regularly. In this write-up, we will discuss the importance of touch calibration for MCGS HMI and provide a step-by-step guide on how to perform the calibration.
Why is Touch Calibration Important?
Touch calibration is crucial for MCGS HMI to ensure that the touch screen responds accurately to user inputs. Over time, the touch screen may become less accurate due to wear and tear, environmental factors, or software issues. If the touch screen is not calibrated correctly, it can lead to:
MCGS HMI Touch Calibration Procedure
To perform touch calibration on an MCGS HMI, follow these steps:
Pre-requisites:
Step 1: Enter Calibration Mode
Step 2: Select Calibration Type
Step 3: Perform Touch Calibration
Step 4: Verify Calibration

Conclusion
Regular touch calibration is essential to ensure accurate and reliable operation of MCGS HMI touch screens. By following the steps outlined in this write-up, users can perform touch calibration on their MCGS HMI and maintain optimal system performance. If issues persist after calibration, contact the manufacturer's support team or a qualified technician for further assistance.
Here is the solid, technical content regarding MCGS (Kinco) HMI Touch Screen Calibration.
Unlike Windows-based HMIs (which use a digitizer driver), MCGS HMIs run on an embedded RTOS or Linux. Calibration is typically required when the touch is offset by 1–2 cm or after a firmware update.
For older MCGS units (pre-2018, such as the TPC7062K or TP1062Ti), the operating system does not run Windows CE or Linux. Instead, it runs an embedded proprietary RTOS. On these models, you cannot use OS software tools. You must use the hardware boot-time calibration.
To understand calibration, one must distinguish between two coordinate systems:
The goal of calibration is to find a transformation matrix that converts Physical Coordinates $(X_p, Y_p)$ into Logical Coordinates $(X_l, Y_l)$.
Mcgs (Configuration Software) HMIs, produced by Beijing Kunlun Tongtai, are widely used in industrial automation for their stability and ease of use. However, like all resistive touch screens (common in many MCGS models), they can drift over time due to aging, temperature changes, or physical impact. When your button presses no longer match the intended input, it’s time for a touch calibration. Power off the HMI
Most older or budget-friendly MCGS models use resistive touch technology (pressure-sensitive). Unlike your phone’s capacitive screen, these rely on precise voltage alignment between the LCD and the touch film.
