Sorry I'm answering in English.
I am in the same situation as you - fighting with this issue.
Key word is Simatic Workstation - configure and start server function.
Look up 'Multiproject-Requirements and Recommendations' in the help file.
- The project is on the main engineeringstation, ES01.
- \\ES01\MyProjectfolder is shared.
- On the ES02 I can browse the multiproject and open ONE OF THE PLCS and edit this. Plant view does not show all, but component view is OK.
- I do the compilation on ES01, allways.
