"Coming" => a message is triggered when a
fault is received (start of fault).
"Coming and going" => a corresponding
message is triggered at the start and end of a
fault.
This "Message triggering" applies to device
faults on the KNX network (system) sent via bus
to the central communication unit. The LED
"System" indicates a fault "System".

Command sequence: Settings > Faults > Fault relay > Fault relay 1…2
Data point
Explanation, example
Fault priority
Default val: All
Setting val: Urgent
Not
urgent
All
Setting value "All" means that the fault relays
are controlled for all types of faults (Urgent and
Not urgent).
Setting values "Urgent" and "Not urgent" are
used as a filter, i.e. the fault relays are only
controlled if there is a fault with relevant "Fault
priority".

Fault source
Fault relay 1
Default val:
Fault local (acoustic)
Fault relay 2
Default val:
Fault system (acoustic)
Setting val relay 1 and 2:
Fault local (visual)
Fault local (acoustic)
Fault system (acoustic)
Use setting values "Local" and "System" as
separators to control the fault relays.
Setting value "Local" controls "Fault relay 1" or
"Fault relay 2" only for "Local" faults.
Accordingly, "Fault relay 1" or "Fault relay 2" are
controlled only for "System" faults.
