Every NiagaraStation has a “Files” device extension (NiagaraFileDeviceExt). It can be used in jobs where files need to be transferred automatically from one station to another, for example, reports from a JACE station to a Supervisor station. Or, a JACE station may import file(s) periodically from a Supervisor station, for some specific reason.

This file import feature is also used in some of the “export tags” functions (for Supervisor auto-configuration) first introduced in AX-3.5. Niagara file import descriptors are automatically created on the Supervisor, for example, when using export tags of type “PxViewTag” in subordinate JACE stations. A separate export tag “FileImportTag” is also available. For details, refer to the NiagaraAX Export Tags document.

The Files device extension has no configuration properties apart from a Retry Trigger container, (see About the Retry Trigger), and otherwise contains child “file import descriptors” that you add using the default view, the Niagara File Manager.
