4.4.11 Weekly timer
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.
