Within the BMS Server we can split up complex KNX data point types to different sub fields. For example, to activate the sub fields for a 1 byte DALI object, please open the Telegram Definition, select the corresponding group address(es) and change the data type to : 238.600
After restarting the server, you will find the group address and different subfields:
For example, if the value 67 is received, the BMS Server is splitting up the value into the sub fields. 67 means that the DALI ballast 3 has a Lamp Failure.
If you want to send a KNX telegram, you can also use the sub fields. For example of DPT 238.600, if you want to request the status of a DALI ballast, you have to set the sub field .Address to the corresponding address, and .LF and .BF to False. Afterwards, when you set the “- SEND” item to True, the BMS server calculates the value from the different sub fields and then it sends the calculated value to the KNX bus.
