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 SystemDb.

Figure 54. Niagara File Import properties

Expand Config > Drivers > NiagaraNetwork > NiagaraStation double-click Files and click Discover. When the app finds the files, switch to the Property Sheet by right-clicking Files and clicking Views > AX Property Sheet. 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.
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.
