So, in the same manual have explanation how to divide each byte from date and time variable. And if day byte is equal to 1 this should means Monday...after compare hours with 8 and minutes with 30 (beginning of working day for example is 8.30) the same logic for end of the working day. if we have day equal to 6 or 7 this means (doesn't matter from hours and minutes) non working days. You should build something like this logic with Step7 basic software. Hope I understood exactly what did you mean with programmer working week. best regards, Hristo Mihalev

I hope this helps
