Imports a configuration to the session from either a file or a buffer.

You can export and import supported configurations only between NI‑FGEN devices with identical bus types, model numbers, and channel counts, as well as the same number of initialized channels.

Note You cannot call this VI while the session is in the Running/Generating state.

Supported Configurations

You can export and import the following between NI‑FGEN sessions:

  • Attribute configurations
  • Arbitrary waveforms

Requirements for Exporting and Importing Arbitrary Waveforms

Arbitrary waveforms you export and import between sessions using this VI must meet the following criteria:

  • All waveforms in the exporting session are created from files using the niFgen Create Waveform (poly) VI
  • The full file path of the file containing the arbitrary waveform still exists upon import
  • All waveforms are defined using handles rather than names
  • All waveforms are complete—none are streamed or incrementally written

You can set the device mode with the niFgen Configure Output Mode VI. For more information on arbitrary waveform mode, refer to Arbitrary Waveform Output Mode and Configure Arbitrary Waveform Mode.

Channel Mapping Behavior

When exporting and importing configurations between NI‑FGEN sessions that were initialized with different channels using the channel name input to the niFgen Initialize With Channels VI, the configuration of the exporting channel is mapped to the importing channel.

For example, if your entry for channel name is 0 for the exporting session and 1 for the importing session, the configuration exported from channel 0 is imported into channel 1.

Note This VI will return an error if the total number of channels initialized for the exporting session is not equal to the total number of channels initialized for the importing session.
