For anyone producing their own electrical/control drawings you may have noticed the downloadable blocks in the technical library. Personally I have only ever found these useful for overall dimensions or to show the display on a general arrangement drawing.
It's a shame we don't have anything showing the actual connections in .dwg (a bit like the images in the install guide). Anyway I will post here something which has helped me provide clients with a reference for connections.
These are blocks and in reality the PLC connections will have interconnecting wires and all the usual stuff
