Hi All,

I am facing an issue with my PLC Program in Simatic Manager V5.5. I don't have the Updated Running backup for my system. So, I have uploaded the Backup from PLC which contains no symbols.

Now I am Comparing with my old handover backup. but in my Current backup I am Getting STL programs in my Ladder Logic. So how can I convert this back to Ladder Logic. I have attached the image of the network.

Thanks,

You have to make two networks out of one network. Then append the instruction "NOP 0" after the last instruction.

After that shows it this:
