Associated with: Trends
The Trend - Data In Alarm state indicates when data on a Trend's trace was in an alarm state. Geo SCADA Expert indicates the Trend - Data In Alarm state with a muted red marker (by default) on a Trend’s trace.
If manual data validation is enabled, users could potentially mistake the muted red color of the Trend - Data In Alarm marker for the red color of the Trend - Unvalidated Data marker. To avoid this conflict, you could change the color of one or both of these markers. For more information, see Use the Color Palette to Define a Custom System Color.
When displaying data in an alarm state, Geo SCADA Expert does not take account of whether the alarm was disabled or suppressed. Geo SCADA Expert will show the data as in alarm regardless.
Data on a Trend's trace can be in more than one state. Therefore, Geo SCADA Expert applies a priority scheme to determine the data display color. The priorities, from highest to lowest are: Trend - Bad Data, Trend - Unvalidated Data, Data In Alarm and then Trend - Validated/Good Data.
Your system has manual data validation enabled. If a Trend's trace shows data in an alarm state but the data is unvalidated, Geo SCADA Expert would display the data in red (unvalidated data is the priority). If the data is validated, Geo SCADA Expert would display the data in muted red (data in alarm is the priority).
For data sources that exist in the Geo SCADA Expert database, Geo SCADA Expert obtains the marker color from the data source's Color Palette. The exception to this is if Geo SCADA Expert is unable to obtain the marker color from the server (for example, if communications with the server is interrupted when a Trend is redrawn). In such a situation, Geo SCADA Expert uses the marker color that is specified in the Options window. Geo SCADA Expert also uses the marker color from the Options window for data sources that are from a non-Geo SCADA Expert database (for example, another OPC database).
