Selection "Flashing"
When the flashing function is activated, the output starts to flash as soon as
the object "Switch" receives the corresponding value. The flashing rate can
be set in the parameters ("Time for ON" or "Time for OFF"). At the start of
the flash rate, the output is always switched on. On receipt of a new value at
the object "Switch", the flashing rate starts from the beginning (except if the
flashing has stopped).
As soon as the flashing stops, the output switches off immediately. The
flashing can be inverted whereby the output is operated as a "Normally
closed contact".
Note: If the status response "Status switch" is active, it also indicates the
current state of the relay during the flashing. With a rapid flashing
rate, this can lead to a high bus load.
Parameter: "Flashing if object 'Switch' is"
This parameter sets which value of the object "Switch" causes the output to
flash. It can also be set that the output always flashes.
Parameter: "Time for ON" or "Time for OFF"
This parameter defines how long the output is switched on or off during a
flashing rate. The smallest value each time is a second; a rapid flashing rate
is not advisable due to the maximum switching frequency of the relay
(contact endurance).
Parameter: "Limited number of ON impulses"
The number of flashing pulses can be limited here. After the output has been
switched on and off for an adjustable "Number of ON impulses", it will be
switched off permanently.
