Short description 
The output is controlled by means of a configurable on/off date. The function supports any 
combination of weekdays. You select the active weekdays by hiding the inactive days.     
 
 
Note 
Because LOGO! 24/24o does not have a real-time clock, the weekly timer function is not 
available for both versions.
