| Property | Value | Description |
|---|---|---|
| Name | text (default begins with Local_ for any history originating from the local station. If you are adding a descriptor this property defaults to NiagaraSystemHistoryExport appending numerals as needed to keep unique.) | Provides a name for the object.
Editing this property is equivalent to the right-clicking Rename command on the component. In this case, the object is a history export descriptor. Typically
you leave it at its default value.Editing this name does not affect the name of resulting history that was already exported. |
| History Id | text in two parts: station name/history name | Together the two names identify
the CSV file to import from the local Supervisor PC. Histories originating in the local station show a caret (^), which is shorthand for the local station, and source history names. Typically, you leave both at their default values. |
| Execution Time | additional properties (Trigger Mode defaults to Daily) | Configures a time trigger
that controls when to perform the function. Trigger properties are documented in the Getting Started with Niagara guide. |
| System Tag Patterns | Specifies one or more
text strings matched against text values in the System Tags properties
of a local history extensions, where matching text patterns result
in histories exported into the remote history space. |
