“temperature (°C)”. Therefore if the temperature received via this group address is bigger than or
equal to 30°C, an alarm will occur.
After configuring this new alarm, click on “Ok”. From now every time a KNX telegram will be received with
the group address “14/2/5”, if the value contained in this telegram is bigger than the limit value or equal
to the limit value, an alarm will occur.
Another alarm is added. If the temperature received via the group address “14/2/5” is less than or equal
to -1°C, an alarm will occur.
Alarm States
The “State of group address alarm” field displays the current state of configured alarms. A state contains
one text field containing information about the alarm:
-
Name given to the group address in the ETS4 p group address
-
The current value
-
The limit value
-
The datatype
-
The unit
It contains also a list of date/value. Those are datetimes when an alarm occurred and with which value the
limit has been reached. Finally an “Empty dates” button will simply clear the list of date/value.
Figure 22: Alarm States Green
Every time a telegram is received with a group address configured as alarm, the alarm state is updated. If
limit values are respected the text color stays or turns green. Otherwise if the limit values are reached the
text color stays or turns red.
Alarm notification
If an alarm occurs, it will be notified by different processes. For example a temperature of 32.5°C is
received via the group address “14/2/5”. The limit value 30°C is reached, an alarm occurs.
First of all the “Alarm States” field is updated. The first alarm turns red and a Date/Value entry is added to
the list.

Then, a warning message is displayed on the LCD screen. This message specifies every information about
the alarm and the current value. Finally if Connections are configured, the same warning message will be
sent via those Connections.
