Limit number of telegrams
Options:
The KNX load 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.

Yes: The DLR/S monitors its sent telegrams and limits the telegrams sent depending on the following
two parameters, which appear with the Yes option:
46 2CDC 507 100 D0202 | DLR/S 8.16.1M
Object value to be sent
Options: 1/0
Using this parameter, you determine whether the DLR/S cyclically sends a telegram with the value
1 or 0 on the KNX.
Telegram is repeated every
in s [1...65,535]
1...60...65,535
Options:
Here, the time interval at which the DLR/S cyclically sends an In operation communication object
telegram is set.
No
Yes
Maximum number of sent telegrams
in s [1...255]
1...20...255
Options:
In period
50 ms/100 ms...1 s...30 s/1 min
Options:
This parameter defines the number of telegrams sent by the DLR/S within a period of time.
The telegrams are sent as quickly as possible at the start of a period.
Note
The DLR/S counts the number of telegrams sent within a parameterized period. As soon as the
maximum number of sent telegrams is reached, no further telegrams are sent on the KNX until
the end of the period. A new period commences at the end of the previous period. The telegram
counter is reset to zero, and sending of telegrams is allowed again. The current communication
object value at the time of sending is always sent.
The first period (break time) is not predefined exactly. The period can be between zero seconds
and the parameterized time. The subsequent sending times correspond with the parameterized
time.
Example:
Maximum number of sent telegrams = 5, period = 5 s
20 telegrams are ready to send. The DLR/S immediately sends 5 telegrams.
The next 5 telegrams are sent after a maximum of 5 seconds.
From this point, a further 5 telegrams are sent on the KNX every 5 seconds.
