In your S5 Program did you remove all "Siemens Protected Blocks" and OB's ?? Regards / M.f.g

sps-concept Posts: 642 Rating: (131)	Hello, sort the blocks in the awl-file. First the blocks without call-instruction, then blocks with call-instructions.

sakubh Posts: 3 Rating: (1)	This error is because you don't have this system block in your project(in Simatic Manager). Add function "S7Program>Blocks>Insert New Object>Function". Open this function to edit, on left side of editor you have folder "Libraries>Standard Library>S5-S7 Converting blocks". Add function number that you have in error to you function, after this move, you will have in Simatic Manager this system function and error will disapear after next compilation.
