Logic functions | Logic gate
Input 2
Inputs of a logic gate can be activated or deactivated separately. This allows gates
with an individual number of inputs (1 ... 4) to be implemented. This parameter
defines whether the second input of the gate should be used.
This parameter is only visible if "Type of logic function = logic gate".
Input 3
Inputs of a logic gate can be activated or deactivated separately. This allows gates
with an individual number of inputs (1 ... 4) to be implemented. This parameter
defines whether the third input of the gate should be used.
This parameter is only visible if "Type of logic function = logic gate".
Input 4
Inputs of a logic gate can be activated or deactivated separately. This allows gates
with an individual number of inputs (1 ... 4) to be implemented. This parameter
defines whether the fourth input of the gate should be used.
This parameter is only visible if "Type of logic function = logic gate".
Invert input
It is possible to invert inputs of the logic gate as an option. This parameter is avail-
able for each input of the gate and defines whether the respective input should be
evaluated unchanged or inverted.
This parameter is only visible if "Type of logic function = logic gate".
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 pro-
gramming 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 in-
put. At the same time, the cycle time for cyclical transmission is restarted!
