AVEVA Insight supports Wonderware Application Server events captured through Wonderware Historian replication or the Wonderware Historian SDK. (For more information on Application Server events, see the Wonderware Server Platform 2017 documentation.)
When you chart tags with associated events on a line chart, those events will be displayed as part of your line chart.
On a line chart, AVEVA Insight can display:
|
|
Alarm state Note: If either the Alarm.Set or Alarm.Clear for an alarm occurs outside the displayed timeframe, the highlighted are will still display. However, if both Alarm.Set and Alarm.Clear for the same alarm occur outside of the displayed timeframe, the highlight will not be displayed. |
|
|
Alarm Acknowledge event |
|
|
Application Write event |
|
|
User Write event |
|
|
User Write Secured event |
|
|
User Write Verified event |
|
|
Multiple events If you zoom in, you will see individual event and alarm icons. If you zoom out far enough, the Multiple Events icon disappears. |
Note: Events can appear in the display area for a chart even if no tag data is available.
When the displayed timeframe includes one or more tags with more than 30 events, individual event icons are replaced with Multiple Events icons.
If more than 100 events per tag occur within the displayed timeframe, you'll see no icons Instead, you'll see a toast notification saying there are too many events to display. In this case, you can zoom in to see more events details.
