Mcgs Hmi Touch Calibration Official

Some industrial cabinets use an external MCGS touchpad (trackpad/pointing device) connected via USB or PS/2. These require a different approach, as they do not have a physical screen.

If the registry is corrupted, download the latest firmware from the Kinco / MCGS support website (look for firmware_TPCxxxx.bin). Place it on a FAT32 USB drive named update. Power on the HMI while holding the USB port's detection pin. The bootloader will ignore the corrupt calibration and reload the entire OS.

  • Keep pressing until you see a white or red crosshair appear on a black background.
  • Release all fingers. You are now in calibration mode.
  • Using a stylus or a blunt, non-metallic object (never a screwdriver), press the center of each crosshair as it moves across the screen.
  • Upon pressing the final target, the system will display "Calibration successful. Reboot in 5 seconds."

    • Troubleshooting: If you cannot trigger the calibration with three fingers, your model uses the "System Menu" method (see below).

    What if the screen is so misaligned that you cannot press the Start button? You need a USB mouse. mcgs hmi touch calibration

    Critical Warning for Wince: After calibration, do not perform a "cold boot" (full power cycle) immediately. Windows CE saves calibration to RAM first. You must perform a "warm reboot" via the Start Menu or wait 30 seconds before cutting power.

    Q1: Does MCGS HMI calibration affect my project logic? No. Calibration only changes how touch coordinates are mapped to the screen. It does not alter your tags, alarms, recipes, or ladder logic.

    Q2: How long does calibration take? Less than 30 seconds from start to finish. Some industrial cabinets use an external MCGS touchpad

    Q3: Can I calibrate without a stylus? For resistive screens, it is not recommended. For capacitive screens, your finger is fine.

    Q4: My MCGS screen reboots during calibration. What’s wrong? This indicates a power supply issue. The calibration routine may draw extra current. Check your 24V DC power supply for voltage drop.

    Q5: Is there a difference between "touch calibration" and "screen alignment" in MCGS? No. The terms are used interchangeably. Keep pressing until you see a white or

    Q6: Can I perform remote calibration over Ethernet? Not directly. However, you can use remote desktop software (like VNC) if your MCGS HMI supports it. The remote mouse movements will simulate touches, but you will need someone on-site to press the physical targets.

    You perform the 5-point calibration, reboot, and... it’s wrong again. This indicates one of three issues:

    | Symptom | Likely Cause | Fix | |---------|--------------|-----| | Drift returns after power cycle | Dead backup battery (on older units) | Replace CR2032 battery on mainboard | | Crosshairs jump during calibration | Dirty screen or debris under bezel | Clean edges with compressed air | | One axis works, other is inverted | Corrupted touch driver | Re-flash MCGS firmware via USB |

    | 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 |

    Modern MCGS devices (TPC7032Kt, TPC1071Gi, TPC1262Hi) run Windows CE 6.0 or newer. These require calibration via the operating system's touch panel driver. This is the most common scenario for users searching for "MCGS HMI touch calibration."
