Yearly timer

Short description
The output is controlled by means of a configurable on/off date. You can configure the timer
to activate on a yearly, monthly, or user-defined time basis. With any mode, you can also
configure the timer to pulse the output during the defined time period. The time period is
configurable within the date range of January 1, 2000 to December 31, 2099.
Note
Because LOGO! 24/24o does not have a real-time clock, the yearly timer is not available for
both versions.
