﻿### Transmission criteria

The transmission behaviour of the output can be configured here.

*Always transmit when the input is updated*: The output transmits the current object value to the KNX with every telegram that is received at the input.

*Transmit only if the output changes*: The output only transmits the current object value if the object value has changed compared to the last transmission process. During the first telegram to an input after bus voltage return or after an ETS programming operation, the output always transmits to an input.

*Transmit cyclically*: With this setting, the output transmits the current object value to the KNX cyclically. After bus voltage return or after an ETS programming operation, the cyclical transmission is only started once the first telegram has been received at the input. The output also transmits as soon as a new telegram is received at the input. At the same time, the cycle time for cyclical transmission is restarted!
