• Acknowledgement of alarms: The main purpose of alarms is to inform the user on

alarm situations. In doing so it often is necessary to make sure that the user has

noticed this information (see possible actions assigned to an alarm in the alarm

class configuration). The user must acknowledge the alarm in order to get the

alarm removed from the alarm list.

• Alarm Event: An alarm event must not be mixed up with an alarm condition. While

an alarm condition can be valid for a longer period of time, an alarm event just

describes the momentary occurrence of an change, e.g. a change from the normal

state to the alarm state. In the PLC Designer alarm configuration for the three

types of events and the corresponding alarm states the same names are used

(INTO, ACK, OUTOF).

In »PLC Designer« the following features are supported:

• Deactivation of the alarm generation for single alarms as well as for alarm groups

• Selection of the alarms which should be displayed by defining alarm groups and

priorities

• Saving of all alarm events in an alarm table

• Visualization element 'Alarm table' in the PLC Designer Visualization
