Dear All,

We get an old assemby machine with CPU 314C-2 PN/DP, without the original project.
I upload the program from the PLC but some blocks are written in S7-Graph. (Simatic manager V5.6)
I can not open it in Graph format but as I know it is normal in this case. It is only possible if I have the original project, otherwise open it is only possible in STL format.

I tried this I can read and edit it in STL, but I do not understand the complett Graph method in this way.
I see the Transfers, and its condition. Also see the Steps and what it set.
But I do not know the connections between the steps. Which Transfers connect the steps?
Is it  possible to get only from the STL file?
I attached the printed out block.

Thanks in advance
