Need the official calibration PDF for your exact MCGS model? Search for "Kinco [Model Number] Hardware Manual" — the calibration procedure is always listed in Section 4.2 (System Maintenance).
Follow these steps to initiate and complete the touch calibration: Enter Boot Setup Cycle the power to the HMI (24V DC). During boot-up, a progress bar will appear with a
If the HMI keeps asking for calibration, the internal memory (EEPROM) that stores the calibration data may be faulty.
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
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 .
: For maximum accuracy, especially near the corners and edges, use a plastic stylus rather than your finger.
There are two primary ways to enter the calibration mode on an MCGS touch screen, depending on whether the device is currently functional or if the touch alignment is so poor that the menus are inaccessible. Need the official calibration PDF for your exact MCGS model
: Press "Yes" to the confirmation prompt to start the alignment process. Quick Tips for Best Results
Before starting the MCGS HMI touch calibration process, follow these steps to ensure a successful outcome:
Power on the MCGS HMI. While the application is loading, or if the screen is accessible, find the "Settings" or "System" button. During boot-up, a progress bar will appear with
| Symptom | Diagnosis | Fix | | :--- | :--- | :--- | | Press Button A, activates Button B | Calibration drift | Re-calibrate via crosshair | | Screen registers random presses when untouched | Hardware noise / Ground loop | Check shield grounding on HMI frame. Replace touch film | | Only the top half of the screen works | Failed resistive layer | Hardware replacement required. Calibration cannot fix dead zones | | Cursor jumps wildly during calibration | Dirty screen or damaged digitizer | Clean with microfiber cloth. If persists, replace overlay |
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.
