Triggers - Basic

There is also an advanced dialog that allows you to specify a precise mask of when the trigger should fire, using a
combination of year, month, day of the month, day of the week, hour, minute or second. Highlighted values are
included in the mask and make sure all values are highlighted in any column you don't care about. The trigger will
fire at all times that match the specified mask in all columns - so no column should be blank or the trigger will
never match:

Further information about the use of the real time clock can be found in the

conditions

chapter.

In the Network view, a

Controller properties

option exists to "execute real time triggers on startup". This will

ensure that all real time triggers are executed from a user-specified time to the current time to reinstate the correct
playback state in case the Controller is restarted for some reason (eg.power loss, watchdog or remote reset).

NOTE: Real Time triggers are only tested by the Time Server and then shared over the network so any conditions
are tested on the Time Server only.

Astronomical

The Controller is also equipped with astronomical clock algorithms which automatically generate the correct sun-
rise, sunset and twilight times for the location of the installation (see

project properties

), use the configuration

pane to select between sunrise, sunset, dawn or dusk and to specify an offset, negative or positive, in minutes.

Two versions of dawn and dusk are offered, using the two definitions of twilight: civil and nautical. Please see

Wikipedia

for an explanation of these terms.
