9.2.3 Alarm signalling
If you do not have a central management system, you could perform alarm signalling with the alarm
contacts of the CN4 card nest (this applies only to the crocusIfConvNx64<Tt/Cv>).
Example
Suppose the following situation:
• On a remote Crocus CNV TT the configChanged alarm of the crocusIfConvNx64Tt object is set to enabled in
the remoteAlarmMask. In other words: crocusIfConvNx64Tt /remoteAlarmMask/configChanged = enabled.
• On a central Crocus CNV CV the remoteAlarm of the top object is set to enabled in the
alarmContactHighMask. In other words: crocusIfConvNx64Tt /alarmContactHighMask/remoteAlarm = enabled.
• The high alarm contacts of the CN4 card nest are connected in a circuit with a light bulb.
Now the following happens:
Phase Situation Result
1 Someone changes the configuration of the
Crocus CNV TT.
On the Crocus CNV TT the configChanged
alarm becomes active.
2
On the Crocus CNV TT the configChanged
alarm is enabled in the remoteAlarmMask.
A remote alarm is sent to the Crocus CNV
CV.
3
On the Crocus CNV CV the remoteAlarm is
enabled in the alarmContactHighMask.
The high alarm contacts of the CN4 card
nest close.
4 The high alarm contacts of the CN4 card
nest close.
The light bulb lights up.
