My advice is to obtain a newer step 5 package. Version 3 is very old and will not run on any modern OS. You would need a machine with DOS 5 or similar. Win 9X or above will not run it even in DOS mode.
Hello Nada,
I need general documentation on how to program an S5 plc. I can't figure out what the different block types are used for. My experience is with American ladder logic and the S5 has me confused.
