The "Gate" application allows specific signals to be filtered and the signal flow to be temporarily blocked. The
function has three communication objects: "Control input", "Input" and "Output".
The input or output object can assume different sizes.
The bit size can be freely assigned with the "Not assigned" setting. This means that the first internal or external
group address/action that is assigned and already connected to some other communication object will specify the
size.
The control can occur from "Input to output" or also from "Output to input", provided the control input allows this.
Enabling via the control input can occur via an ON or an OFF telegram.
If, for example, the "Control input" setting is set to "ON telegram", only telegrams from the input are transmitted to
the output, if prior to this the control input has received an ON telegram.
It is also possible to block signals via the "Filter function" setting. Either "nothing is filtered out" or the signal "ON
is filtered out" or the signal "OFF is filtered out". This function is always necessary, for example, when only the
ON telegram is interesting for a sensor and the sensor does not offer any filter function in its application program.

With the "Staircase lighting" application, switching telegrams or value telegrams can be provided with a light-on
time.
Depending on the parameterisation, the application shows different communication objects:
– a 1-bit object for input and output
If an ON telegram is received via the "Input/Output" object, the light-on time is started immediately. This can
be a light-on time of 00:10 min to 88:45 min, which is adjustable in 0.1 s steps. After expiration of the light-on
time, the "Input/Output" object sends an OFF telegram.
– two 1-bit objects for input and output
– two 1-byte objects for input and output
If a telegram is received via the "Input" object, the light-on time is started immediately and a telegram with the
same value of the telegram received on the input is sent out on the "Output" object. This can be a light-on
time of 00:10 min to 88:45 min, which is adjustable in 0.1 s steps. After expiration of the light-on time, the
"Output" object sends out an OFF telegram (1-bit) or a telegram with the value "0" (1-byte).
Via two additional communication objects, it is possible to specify the light-on time and the switch-off
prewarning time. The 2-byte values received are written to the memory of the device and are retained even
after a bus power failure and subsequent return of voltage.
