Rate of telegrams
Options: not
limited
1 Telegram / Second
2 Telegrams / Second
3 Telegrams / Second
5 Telegrams / Second
10 Telegrams / Second
20 Telegrams / Second
The load on the bus generated by the device can be limited with the
limitation on the number of telegrams sent. This limit relates to all telegrams
sent by the device.
x* Telegrams / Second: Within a second, x telegrams are sent as quickly
as possible on the bus.
Note
The device counts the number of telegrams sent within a second. As soon
as the maximum number of sent telegrams is reached, no further
telegrams are sent on the KNX until the end of the second. The telegram
counter is reset to zero, and sending of telegrams is allowed again after
the second has timed-out. The current communication object value is
always sent at the time of transmission.
Example:
Maximum number of sent telegrams = 5,
20 telegrams are ready to be sent. The device immediately sends 5
telegrams. The next 5 telegrams are sent after a maximum of 1 second.
From this point, a further 5 telegrams are sent on the KNX every second.
x = 1,2,3,5,10 or 20
Send cyclical "In operation" telegram
(0..65,535s, 0 = inactive)"
Options: 0…65,535
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.
Note
After bus voltage recovery, the communication object sends its value after
the set sending and switching delay.
In order to keep the bus load to a minimum, the time interval of the send
interval must be selected as long as possible in dependence on the
application.
