Hi,
I have programmed a time scheduler to manipulate 3 shifts (morning, afternoon, evening). To do this I have a bit matrix with 3 rows 1 per shiftand 7 columns one per day of week.
I call a subroutine who returns a variable saying if I have to work or not. First I havereset this variable and then if it is a national holiday it executes a ret. If this is not the case,I check the day of week and time to set the variable.

Do you have any suggestions oristhereany standard to do this ?

Thanks in advance
Regards
Fernando

Hi,

Have you though about the time change from summer timeto winter time and back?

May be there is a library available for the things you need, see http://support.automation.siemens.com/WW/view/en/10805397/133000
