Commissioning
If communication objects are read during the sending and switching delay
(e.g. by a visualisation system), these read requests are stored and a
response is sent after the send and switching delay has been completed.
An initialisation time of about two seconds is included in the delay time.
The initialisation time is the time that the processor requires to be ready
to function.
Note
The first switching action will only be initiated when enough energy is
available to switch all contacts safely to the parameterised switching state
with a bus failure. This can mean that the initial switching action will occur
at a later time than intended by the parameterised switching delay.
The send delay is not influenced by this measure.
The maximum switching operations per minute of the relay should be
taken from the Technical
Send object "in operation"
Options: no
send value 0 cyclically
send value 1 cyclically
The in operation communication object indicates the correct function of the
device on the bus. This cyclic telegram can be monitored by an external
device. If a telegram is not received, the device may be defective or the bus
cable to the transmitting device may be interrupted.
•
no: The communication object In operation is not enabled.
•
send value 0 cyclically: A telegram with the value 0 is sent cyclically
by the Light Controller on the KNX via the in operation telegram
communication object.
•
send value 1 cyclically: A telegram with the value 1 is sent cyclically
by the Light Controller on the KNX via the in operation telegram
communication object.
If cyclic sending of a telegram is selected and additional parameter appears:
Sending cycle time in s [1...65.535]
Options: 1...60...65.535
The sending cycle time determines the time interval after which a
telegram parameterised with the value 1 or 0 beforehand is sent
cyclically.
Limit number of telegrams
Options: no
yes
In order to limit the bus load caused by the device, it is possible to
parameterise a limit on the number of telegrams.
•
yes: The following parameters appear:
