Hi,

I'm working with a running HMI MP377 15" touch daylight readable. What I'm trying to do is extracting program from the HMI without affecting its operation.

Can you give me some advice and tutorials (if possible)? I prefer upload program to a USB, then connect the USB to PC later for extracting, but I have no idea if the HMI need to restart before identifying the USB.

In the worst case (can not get program without interrupt the HMI), can I observe all variables and preferences via HMI screen?

Hi ChristophD,

Thank you for replying to my topic.

Based on your answer and some further searching, here's what I understand:

-If the program was downloaded to HMI with "backtransfer enabled", then now, I can connect my PC to HMI via Profinet port on the HMI, then backtransfer the .pdz file to PC. Also, the idea of using USB (as I mentioned before) is impossible.

-If the backtransfer was disabled, then there is no way for me to get the program through HMI.

Is that right?
