Alarm handler
Application
The alarm handler provides an infrastructure for activating and managing alarms on the
NCK.
Functions
• Buffering of a maximum of 16 alarms that have been activated since system powerup and
which have not yet been reset.
• Alarm reactions can be programmed as channel-specific, modegroupspecific or NCK-
specific reactions.
• The "NoReady" alarm reaction can also be programmed as a channel-specific reaction.
Activation
The alarm handler is activated when an error status is detected in the NCK, causing an
alarm to be output.
It is possible to trigger an alarm in a part program using the SETAL command.
Reference: /PGA/ Programming Guide Advanced
Note
The currently active alarms in the NCK are read via the operator panel interface.
It is not possible to set alarms externally in the NCK.
Alarms with an alarm ID in the 60000 to 60999 range can be activated in a part program.
Data backup
At POWER ON, the alarm handler data is completely reinitialized since it is not stored in the
buffered SRAM.
