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.
