Send telegram “Fault Ballast”:
In the setting “no”, the function and the
communication objects are not available. In the parameter setting “only on
read request”, the object value “Channel X - Telegr. Fault Ballast” can only
be read out after a read request. In the setting “on change of status”,
the current fault status is sent automatically via the communication object
following a change.
Send telegram “Fault Lamp”:
In the setting “no”, the function and the
communication objects are not available. In the parameter setting “only on
read request”, the object value “Channel X - Telegr. Fault Lamp” can only be
read out after a read request. In the parameter setting “on change of status”,
the current fault status is sent after a change.
Send telegram “Fault DALI”:
In the setting “no”, the function and the
communication objects are not available. In the parameter setting “only on
read request”, the object value “Channel X - Telegr. Fault DALI” can only be
read out after a read request. In the parameter setting “on change of status”,
the current fault status is sent after a change.
Send telegram “Fault 230 VAC”:
In the setting “no”, the function and the
communication objects are not available. In the parameter setting “only on
read request”, the object value “Channel X - Telegr. Fault 230 VAC” can only
be read out after a read request. In the parameter setting “on change of
status”, the current fault status is sent automatically after a change.
Note: This fault affects the operating voltage of the DALI Gateway and can
also be DC operating voltage.
Acknowledge faults:
In the setting “no”, a telegram is sent via the KNX
via the corresponding communication object when a fault occurs (ballast,
lamps, DALI, 230 VAC). As soon as the fault is rectified, a telegram is sent
automatically with the value “0”. The change in the error state can last
45 seconds and is dependent on the number of DALI devices connected.
In the setting “yes”, a telegram is also sent when a fault occurs. This fault
signal remains set however until the fault is rectified and the fault signal is
reset via the communication object “Fault Acknowledgement”. Only then
a telegram with the value “0” is sent via the corresponding communication
object. This can be very helpful for the detection of sporadic faults or events
which take place during unmanned monitoring periods.
Send / receive communication telegram cyclically:
In the setting “no”, the functions and the communication objects are not
available. The DALI Gateway does not send a monitoring telegram and thus
does not check the KNX bus in order to monitor the communication path.
In the setting “send telegram”, a telegram is sent cyclically via the KNX to
signal the presence of the DALI Gateway.
In the setting “receive telegram”, the DALI Gateway expects a cyclically
transmitted telegram which indicates the communication capability of the
KNX. If the DALI Gateway does not receive a telegram within a specific time
interval, a fault in the KNX communication path is assumed and a response
defined in the
General
parameter window (section 4.3.1) is carried out.
The time span of the receiving interval can be set in the
Status
parameter
window under “Transmission / receive period”.
In the setting “send/receive telegram”, the DALI Gateway sends and receives
a monitoring telegram cyclically with which the communication via the KNX
is monitored.
