9 Sample configurations
Here you will find some sample configurations to explain the configuration principles of our gateway.
9.1
Reading the status of a KNX switch
Assuming the following setup: 1 KNX switch e.g. GIRA with six switches, programmed with KNX group
addresses in the following way:
All six KNX groups send as KNX data a BIT value defining the current state of the switch (0=OFF, 1=ON). If
you press the left, top switch, the KNX device sends the KNX telegram 2.5.30=1 or 2.5.30=0 depending on
the stored switch state in the KNX device.
So the configuration will look like this:
As you can see in the test mode, the switch state of Switch #1 and #6 is ON, all other switches are OFF.
Press the six buttons and see, how the MODBUS registers are changed by the incoming KNX telegrams.
9.2
Writing to a KNX actuator
Using a KNX actuator with four outputs, e.g. an ABB KNX actuator, is also very simple. Assuming the following
KNX group addresses for the four outputs. All of them expect a KNX telegram with bit data.
2.5.40
2.5.41
2.5.42
2.5.30
2.5.31
2.5.32
