While keeping your finger pressed on the screen, turn the power supply back on.
If you can still navigate the screen, you can trigger calibration from the internal system settings. MCGS Touch Screen HMI User Manual (TPC Series)
While the MCGS HMI is running, hold down a specific corner of the screen (usually the top-left or top-right) for 3-5 seconds, or press the System button if available.
In the fast-paced world of industrial automation, precision is everything. A Human-Machine Interface (HMI) acts as the bridge between operators and complex machinery. When that bridge starts behaving poorly—such as registering presses slightly off-center or missing inputs entirely—it can cause immense frustration, slow down production, and even lead to costly safety hazards.
The External Mouse MethodIf the touch is completely unresponsive, plug a standard USB mouse into the HMI’s USB port. mcgs hmi touch calibration
There are two primary ways to enter the calibration mode depending on whether you can still interact with the current screen. 1. The "Long Press on Boot" Method (Recommended)
Make sure the HMI is not prone to power failures during the process, as this could corrupt the system settings. 3. Step-by-Step Guide: MCGS HMI Touch Calibration
: Nearby high-voltage equipment or variable frequency drives (VFDs) can distort touch signals. Method 1: The Hardware Button Method (Recommended)
The exact method for accessing the calibration utility can differ slightly between specific MCGS models (e.g., TPC series), but the following steps cover the standard procedure. Method A: Calibration via System Settings (Most Common) While keeping your finger pressed on the screen,
For high-use machines, consider checking and performing MCGS HMI touch calibration once a month to prevent frustrating inaccuracies.
For facilities where operators cannot access the system menu, add a hidden button in your MCGS project. Use the !RunApp("control.exe", "stylus") command in a script to launch the calibration control panel applet directly. This gives maintenance teams easy access without a mouse.
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.
MCGS HMI Touch Calibration: Comprehensive Setup Guide is the critical process of aligning a screen's physical touch coordinates with its internal software layout. MCGS (Machine Control and Gateway System) panels, manufactured by Kunlun Tongtai , widely serve industrial environments. Over time, physical stress, temperature shifts, or electrical noise can cause a "touch drift" where your finger taps an on-screen button but the system registers the action elsewhere. In the fast-paced world of industrial automation, precision
Regular calibration is part of standard industrial maintenance, but it is necessary immediately if you experience the following:
Mastering MCGS HMI Touch Calibration: A Complete Technical Guide
You have to touch slightly above, below, or to the side of a graphical button for it to activate.
Resistive touch screens have a finite lifespan. If the screen has been jabbed by metal tools or scratched, the membrane layers may fail.
