The fault with the highest priority is sent over the KNX bus. If more than one fault
with priority "urgent" is pending at the fault input, “>1 fault input faulty” is sent with
the highest priority. Without this fault message, only the message from one fault
input would be known. The newly arriving fault message can be displayed on the
Info level under "Fault status message bus".
