Planning and application
Example
If both communication objects Logical connection x are activated, a
telegram received via a communication object Switch is connected to
them. The result of this action serves as the input signal for the time
function. If this is not blocked, a corresponding switch signal is generated,
e.g. delay or flashing. Before the switch telegram of the relay is reached,
the communication objects Safety priority x and Forced operation are
checked and undertaken, if required, as a priority. Subsequently, the
switching action is only dependent on the state of the bus voltage. The
relay is switched if a switching action allows it.
The function Time can be enabled (value 0) and disabled (value 1) via the
bus (1 bit communication object Disable function time). The output operates
without a delay as long as the function Time is disabled.
Different functions can be realised using the function Time:
Staircase light

Switching ON and OFF delay

Flashing

The output switches off automatically after the staircase lighting time T
For every telegram with the value 1, the staircase lighting time restarts
("retrigger function"), unless the parameter Extending staircase lighting by
multiple operation ("pumping up") in parameter window
set to no, no pump up possible.

This corresponds with the basic response of the function Staircase lighting,
as long as a warning is not parameterised.
