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 by the telegram rate. This limit relates to all
telegrams sent by the device.
•
x* Telegrams / Second
: within a second, x telegrams are sent as quickly as possible via the bus.
Please 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 via KNX until the end of the second. The
telegram counter is reset to zero, and sending 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 send. 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 via 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 communication object
In Operation
indicates that the device on the bus is working properly. This cyclic
telegram can be monitored by an external device.
Please note
After bus voltage recovery, the communication object sends its value after the set sending and
switching delay.
To keep the bus load to a minimum, the longest possible transmission time interval should be selected,
based on the application.
