Hi there guys I wanted to know if it is possible to upload a WinCC program from a HMI if you lost the source code. Is it possible just to connect and upload as you would do with a plc program?
If you just wanted to create a backup of the running app you could use pro-save.
You can drop the project to an identical replacement.
As far as opening the project/Development though, the answer is no. you'll need the source code.
