You can log data historically for points on Kingfisher outstations.
Define whether Geo SCADA Expert retrieves any logged data using the fields within the Logged Data section of the <Point Type> tab of the appropriate Point Form:
Use this check box to specify whether Geo SCADA Expert is to retrieve logged data for the point.
Leave the check box clear if retrieval of logged data is not required.
Select the Enabled check box if you want Geo SCADA Expert to retrieve any logged data from the outstation for this point. If you enable the Logged Data function, you also need to have logging enabled on the Historic tab for the point. The Historic tab defines how data is stored historically on the Geo SCADA Expert server, whereas the <Point Type> tab defines how data is stored historically at the outstation.
If you enable the Logged Data function, the other fields within the Logged Data section of the Form become available for use.
Use this field to define how the Geo SCADA Expert server processes the data that it retrieves from the outstation, specifically when it raises and clears point alarms.
Choose All Data, Logged Data Only, Most Recent Data, or Most Recent Logged Data, as appropriate. For more information on each option, see Processing Alarm Data for Point States in the Geo SCADA Expert Guide to Advanced Drivers.
Geo SCADA Expert interprets the Priority field that is included with every data value from a Kingfisher outstation, to derive why each value was logged. The information appears in the ‘Reason’ column when the data is displayed in a Historic List.
For analog and counter points, Geo SCADA Expert supports these Priority values:
- 0—Value Change
- 1—State Change
- 2—Timed Report
- 3—End of Period
- 4—End of Period Reset.
(For more information on End of Period and End of Period Reset values, see End of Period in the Geo SCADA Expert Guide to Core Point Configuration.)
Any other Priority value is logged as a Value Change.
For digital points, Geo SCADA Expert supports these Priority values:
- 0—State Change
- 1—Timed Report.
Any other Priority value is logged as a State Change.
Where Geo SCADA Expert communicates with Kingfisher outstations in a Master/Slave setup (see Typical Master/Remote Scenarios), each Kingfisher Remote outstation logs data into its memory via the standard Kingfisher ladder logic. The Kingfisher Master outstation polls its Remote outstations for event logs. The Master outstation stores the logged data that it retrieves from its Remote outstations in its memory, along with an index reference for each log file. This information is uploaded from the Kingfisher Master outstation and placed into the Geo SCADA Expert database.
