niagaraDriver-NiagaraFileImport
This component is an import descriptor that specifies a file or folder of files (including all subfolders and files) to be imported to the local station, sourced from the remote Station in a single-tier or multi-tier Niagara system.
Expand . double-click Files and click Discover. After the discovery job finds the files, select the ones you wish to add to the Database and click Add. Additionally, you can create a new file import descriptor by clicking New. Switch to the Property Sheet by right-clicking Files and clicking . Then, to open the view above, expand the NiagaraFileImport descriptor.
In addition to the standard properties (Status, Enabled and Fault Cause) these properties configure this component.
| Property | Value | Description |
|---|---|---|
| State | read-only | Reports the current state of
the data transfer as: Idle, Pending or In Progress. |
| 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. |
| Last Attempt | read-only | Reports the date and time
of the last attempted execution. |
| Last Success | read-only | Reports the date and time
of the last successful execution. |
| Last Failure | read-only | Reports the date and time
of the last execution failure. |
| Route To Station | text | As of Niagara 4.13 and later, optionally specifies a route of intermediate
station names (delimited by semi-colons) to reach the remote, reachable
station from which to perform the file import operation. If the field remains empty, the file is imported from the directly connected station (just like the pre-Niagara 4.13 behavior). If a station route is provided, the file is imported from the downstream reachable station (the final station name in the list) and transmitted through all intermediate stations, as indicated by the station route, back up to this station. In order to work, it requires active NiagaraNetwork connections for all intermediate stations specified in the route. |
| Files | text | Selects the receiving target
and sending source file (or directory) pair(s). |
| File Overwrite Policy | drop-down (defaults to Checksum) | Selects the criterion
to apply to overwrite existing files upon any import execution: Checksum compares a checksum from the file being imported with the checksum from the existing file. If the app finds a difference, it imports the file again and overwrites the existing file. Last Modified compares the date and time stamps of the existing and imported files. Any remote files found with a more recent date or time overwrite the existing files. |
