The probe capacitor polarity needle has a head diameter of 5.8 mm, and the total length of the 7-pin and 12-pin needles is 5 mm.

When first contacting the Siemens touch screen, the younger brother had several questions: How to configure the MP377 so that it doesn't automatically launch the screen program after power-on? How can he exit the program once it's running (such as when wanting to access the control panel)? And how to delete existing programs?

A: Performing an OS update will erase all programs stored on the touch screen.

Here are the steps to perform an OS update:

1. Power on the HMI device and establish a hardware communication connection. Then, set the download path in the control panel.
2. In the configuration computer’s WinCCflexible software, select the menu command "Project > Transfer > Communication Settings". This will open the "Communication Settings" dialog.
3. Choose the correct HMI device type from the list.
4. Configure the connection parameters accordingly.
5. Click "OK" to close the dialog.
6. Go back to the main menu and select "Project > Transfer > Update Operating System" in WinCCflexible.
7. In the "Image Path" section, locate and select the folder containing the HMI device image file with the .img extension.
8. The HMI device image file can be found in the "WinCCflexibleImages" directory within the WinCCflexible installation folder, or on the corresponding installation CD.
9. Click "Open" to proceed.
10. Once the image file is loaded, the version information of the HMI device image will appear in the output area.
11. Finally, click "Update OS" in WinCCflexible to start the operating system update. Follow the on-screen instructions carefully. A progress status view will appear during the update process.

It's important to note that the OS update may require the MP377 to be powered on multiple times. You can try this a few times and power it up immediately after booting. It's also recommended to have someone assist you during the process. Make sure not to close any antivirus software or firewall during the update to avoid potential interruptions.
