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 channelspecific, modegroupspecific or NCKspecific reactions.
• The "NoReady" alarm reaction can also be programmed as a channelspecific 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 language command.

should be taken from the documentation of the machine tool OEM.
