**Optimizing Data Transfer for Siemens HMI MPI 377: A Step-by-Step Guide** Good morning! We are currently dealing with a Siemens HMI MPI 377 with a 19-inch display. Although the screen appears black, it is still operational. Unfortunately, we don't have a backup of the system. We have acquired a new screen, and I would like to know the steps to take in order to retrieve a backup from the existing HMI and transfer it to the new screen efficiently. Utilizing relevant keywords can enhance your query's visibility in search engine results.
To create a backup efficiently, utilize the SIMATIC ProSave software. Discover more details and instructions on the official Siemens support page [here](https://support.industry.siemens.com/cs/document/10347815/servicetool-simatic-prosave?dti=0&lc=en-WW).
Thank you for your assistance; however, my old screen remains black, preventing me from accessing transfer mode to create a backup. I am new to this process.
To attempt this, you'll need to skillfully hit the "Transfer" button blind. My recommendation is to first disconnect your MP377 from the PLC and then attempt to press the "Transfer" button a few seconds after powering it on. Afterward, experiment with the Backup function in Prosave. Should this fail, simply power down and start over. For guidance, here’s an image indicating the approximate location of the button: [view image](https://goo.gl/images/z24SYG).
Despite numerous attempts, I am unable to resolve the issue—my screen remains black. Additionally, the touch functionality is unresponsive, although I can see a faint light along the edges.
If you're familiar with the IP address of the MP377, you can attempt to establish a connection by linking your computer to it via an Ethernet cable. Make sure to configure your Ethernet adapter with a similar but distinct IP address, such as assigning your PC to 192.168.0.x if the MP377 is set to 192.168.0.1, keeping 'x' as any number between 2 and 254. The SmartService feature could be enabled by the developer, allowing you to potentially access it by entering the MP377's address into your web browser, like Internet Explorer (e.g., http://192.168.0.1). If prompted for a password, you might try using '100'.

Answer: 1. Connect the HMI to your PC using the appropriate communication cable (e.g., MPI or Ethernet, if available). 2. Open Siemens software such as TIA Portal or WinCC Flexible on your PC. 3. Establish a connection to the HMI by configuring the communication settings. 4. Use the software to upload the existing project/data from the HMI to your PC. 5. Save the uploaded project/data as a backup file.
