ABB i-bus® KNX PARAMETERS
7.3.1 Sending and switching delay after bus voltage recovery
This parameter can be used to set the sending and switching delay after bus voltage recovery.
During the sending and switching delay, telegrams are only received. No telegrams are sent on the prod-
uct ABB i-bus® KNX. The state of the outputs remains unchanged.
Telegrams are sent again after the sending and switching delay expires. The state of the outputs is set in
accordance with the parameterization or the group object values.
If group objects are read (e.g. from visual display systems) via the product ABB i-bus® KNX during the
sending and switching delay, these requests are stored and answered after expiry of the sending and
switching delay.
The sending and switching delay includes an initialization time of around two seconds. The initialization
time is the time that the processor requires before it is ready to function.
After bus voltage recovery, telegrams are sent on the product ABB i-bus® KNX after expiry of the sending
and switching delay.
The device draws energy for switching the outputs via the product ABB i-bus® KNX. After bus voltage
is applied, it takes about 10 to 30 seconds before sufficient energy is available to switch all contacts si-
multaneously.
The first contact is not switched until the device has stored sufficient energy to switch all outputs to
the set switching state in case of bus voltage failure.
Options
00:00:02 ... 00:04:15 hh:mm:ss
7.3.2 State after sending and switching delay has expired
This parameter can be used to define whether values that were received during the transmission and
switching delays will be processed.
Options
Last value received
Ignore received values
7.3.3 i-bus® Tool access
This parameter can be used to limit or deactivate access of the i-bus® Tool.
The interface to i-bus® Tool is not available for Application V1.0. It will be implemented with the next
version.
Options
Full access
Deactivated
Value display only
Note
The last value received during the sending and switching delay is processed.
Values received during the sending and switching delay are ignored.
Note
The values can be displayed and changed in the i-bus® Tool.
Access of the i-bus® Tool is deactivated.
The values can only be displayed in the i-bus® Tool. The values cannot be changed.
