After updating the Siemens MP277 touch screen OS, your existing program will be lost. It's crucial to back up your active program before performing any OS update. Here’s a step-by-step guide on how to update the operating system: 1. Power on the HMI device and establish a hardware communication connection. Set the download path in the control panel. 2. In the WinCCflexible software on your configuration computer, go to the menu command "Project > Transfer > Communication Settings." 3. A "Communication Settings" dialog will appear. Select the correct HMI device type. 4. Configure the connection parameters accordingly. 5. Click "OK" to close the dialog. 6. Navigate to "Project > Transfer > Update Operating System" in WinCCflexible. 7. In the "Image Path" section, choose the folder that contains the HMI device image file (.img). 8. The HMI device image file can typically be found in the "WinCCflexibleImages" directory within the WinCCflexible installation folder or on the corresponding installation CD. Once you've selected the image file, the version information of the HMI device image will be displayed in the output area. Then, click "Update OS" in WinCCflexible to start the update process. Follow the on-screen instructions carefully. A status view will show the progress of the update. Keep in mind that the OS update may require the MP277 to be powered on multiple times. It’s recommended to try the process a few times and power it up immediately after booting. Having someone assist you during this process is highly advisable. Also, make sure not to close any antivirus software or firewall during the update to avoid interruptions. Important Notes: - Always back up your project before starting the OS update. - Ensure the HMI device is properly connected and stable throughout the process. - Avoid sudden power cuts or interruptions during the update. - If the update fails, you might need to repeat the steps or seek technical support.
