ABB i-bus
KNX
Parameters
7.2.2
State after sending and switching delay has elapsed
Options:
•
Last value received: During the sending and switching delay, the inputs and outputs continue
reading. They send the current value after the delay has elapsed.
•
Ignore received values: No new values are accepted during the sending and switching delay.
The first value received after the sending and switching delay has elapsed applies.
7.2.3
Limit number of telegrams
Options:
This parameter limits the device-generated bus load. This limit relates to all telegrams sent by the
device.

7.2.3.1
Dependent Parameter
Maximum number of telegrams
Options:
This parameter defines the number of telegrams sent by the device within a certain period of time.
The telegrams are sent as quickly as possible at the start of a period.
The device counts the number of telegrams sent within the parametrized period. As soon as the
maximum number of sent telegrams is reached, no further telegrams are sent on the KNX bus
until the end of the period. A new period commences at the end of the previous period. The tele-
gram counter is reset to zero, and sending of telegrams is allowed again. The current group ob-
ject value at the time of sending is always sent.
The first period (break time) is not precisely predefined. It can be anywhere between zero sec-
onds and the parametrized time. The subsequent sending times correspond with the
parametrized time.
Example:
Maximum number of sent telegrams = 5, period = 5 s. 20 telegrams are ready to send. The de-
vice immediately sends 5 telegrams. The next 5 telegrams are sent after a maximum of 5 sec-
onds. From this point, a further 5 telegrams are sent on the KNX every 5 seconds. The telegrams
are sent in the order in which they arise (first in - first out).
