Up to 64 different scenes are managed via a single
group address and the scene number telegram
must match with the scene number previously
configured in the combo parameters. The scene
number (1-64), is used to recall the scene via the
corresponding object. For storage the scene, the
va
lue sent via the object “scene” must be
128+scene number.
When a scene is configured with a
number, the value to send for calling
that scene must be that number -1. For
example, if a scene is configured with
the number 24, the number to be sent
via the
object “scene” must be 23. On
the other hand, the value 152 (128+23)
must be sent for storage the scene
number 24.
The recall of each scene can be delayed whether a
time delay has been defined previously in the
parameter window. This option allows creating
dynamical scene sequences when several outputs
are combined with different delays.
After ETS programming, the scene
values parameterized for the output
concerned will be overwritten into the
actuator. It means that any change made
by the user will be deleted. Therefore it
is important, before any maintenance, to
know the previous scene configuration
and whether the user wants to keep
operating with that configuration.
LOGIC FUNCTION
With the logic function a new communication object
is added (Logic Input) which is logically linked with
the
object “On/Off”. The value of these two objects
is evaluated and then the output will be switched
on or off depending on the result of the logic.
The combo parameters allow defining the status of
the logic input after a bus failure and the ETS
programming.
The logic object will take the values
defined in these parameters but the
reaction of the output after bus failure
will be as it is defined in the parameter
“Behaviour After Bus Voltage Return”.
After the first action, the logic value is
taken into consideration.
