 For S7-300/400/WinAC controllers LAD and FBD programs are first of all

compiled in STL before the machine code is created.

 For S7-1200/1500 controllers all programming languages are directly compiled

into machine code.

2.5 Block creation

All blocks such as OBs, FBs and FCs can be programmed directly in the desired

programming language. Thus no source has to be created for SCL programming.

You only select the block, and SCL as programming language. The block can then

be directly programmed.
