The Tag Historian Query provides a simple way to query data from Tag Historians. In the Tag Historian Query you can collect data from Historical tags for specific date ranges, using aggregations, or for fixed sample sizes. It functions the same as a Tag History Binding and uses the same interface, so check out that page for more information on the individual properties.


The only difference between a Tag History Binding and the Tag History Query is when using indirection. In the Tag History Query, indirection is inserted directly into the Tag Path in the Selected Historical Tags section. Indirection is typically done using a parameter which like the rest of reporting, is the name of the parameter enclosed in { }. In the example below, I have substituted in a parameter 'StationNumber' into my Tag Path for the number of the station.
