Hi everyone,

I encountered an issue while trying to upload a program from a PLC S7-216 in order to convert it to S7-1200. Two blocks (SBR) appear to be empty, and a red message indicates that they are invalid. I’m wondering why they are empty and how to resolve this issue. Any insights or suggestions would be greatly appreciated.

Thank you!
