The logic function is recalculated each time an object value is received.
Example: The gate function is parameterised with "Disable if OFF (0)".
The logic object has the value "0".
The object "Switch" receives the value "1"
No reaction of the output.
Logic object receives the value "1" (gate open)
No reaction of the output
Object "Switch" receives value "1"
Output switches on.
Application: Disable the switching of the lighting.
Only switch the lighting on under certain conditions.
A parameterisable switching state can be retrieved with the help of presets.
Lightscenes can therefore be implemented for example.

Switching states ("preset values") can be retrieved via the object "Call preset
...". A maximum of 4 preset values are available for each output:

Explanation
The result is 1 if both input values are
1.
The result is 1 if one of the two input
values is 1.
The result is 1 if both input values
have a different value.
The object "Switch" is only let through
if the gate is open. Otherwise the
receipt of the object ""Switch" is
ignored.
Example shown here:
Disable if "OFF (0)"
