Alarm Classes for S7 Alarming

[Dag-Are.Trydal@nov.com]

I am looking into the alert system. As I can see there are two standard sets of alarms implemented in the _AlertClass.

The first consists of: advanceAlarm, alert, danger, disturbance, information, scAlarm and warning.

The second is the alarm class for S7 Alarming. Is this set of alarms based on any industrial standard that gives guidelines for what error/alert they are associated with? Also what is the basis for choosing the alert priority?

Hello,

the predefined alert classes are just examples for the different possibilities.
The S7 alert classes are defined for the mapping between S7 alarming and WinCC OA alarming.

For details please have a look at the WinCC OA online help:
Module PARA --> Data point configs --> _alert_hdl (Alert handling)
Drivers --> S7 --> S7 Alarms

Which priority is chosen for which type of alert is defined by the requirements in your project.
