Markers
Markers are a powerful tool for advanced programming technics. Markers are variables
which can have the values 1 (ON) and 0 (OFF) only. The value of each marker can be
altered by actions within scenarios. This makes it possible to visualize certain information
in the marker section of the
web interface. So you could
visualize if a window is open
or if the alarm system is
armed. Also marker states
can be tied to scenarios in
form of conditions, so that a
scenario is executed only if
one or more markers have a
defined state. This is done by
selecting a scenario in the
table
and
opening
the
Marker Selection
window
from the edit- or context
menu. In this window the
desired states of the markers
can be configured which are
required to make this scenario executable. (All markers are in an AND-relation.) If these
states are not met the scenario will not be executed. This allows the creation of so called
IF-THEN statements. Using markers makes it possible to create complex courses of
actions with simple programming tasks.
