Each datapoint can be defined as an alarm datapoint. For binary and discrete values, each possible value in the list can be defined as alarm value. For analogue values, upper and lower alarm limits may be defined.

Each alarm point has an insensivity time period (switch-on delay). After this time span an alarm message is initiated, which can be forwarded to:

• alarm phone call
• SMS message
• pop-up window
• voice message (to the management station sound card).

There is a log of all sent SMS with possible forwarding to another user.

All active alarms and alarm history are shown in the alarm table. The alarms can be filtered and sorted according various parameters, for easy localization of the alarm in the graphics there are “Find in text editor” and “Find in pictures” functions available. Those functions locate and focus the corresponding datapoint in the data table or in the plant graphics.

Alarms are event-driven and shared for all stations in the network, see System topologies.
