Imports a configuration to the session from the specified file.

spd-note-note
Note  

You can export and import supported configurations only between NI-DCPower devices with identical model numbers and the same number of initialized channels.

Programming Patterns

You cannot call this node while the session is in the Running state.

connector_pane_image
datatype_icon

session in

Handle that identifies the NI-DCPower instrument session as previously allocated by Initialize With Channels.

datatype_icon

file path

Absolute path to the file that contains the configuration to import.

If you specify an empty or relative path, this node returns an error.

Default file extension: .nidcpowerconfig

datatype_icon

error in

Error conditions that occur before this node runs.

The node responds to this input according to standard error behavior.

Standard Error Behavior

Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.

error in does not contain an error error in contains an error
If no error occurred before the node runs, the node begins execution normally.

If no error occurs while the node runs, it returns no error. If an error does occur while the node runs, it returns that error information as error out.

If an error occurred before the node runs, the node does not execute. Instead, it returns the error in value as error out.

Default: No error

datatype_icon

session out

Reference to the NI-DCPower instrument session to pass to the next node in the program.

datatype_icon

error out

Error information.

The node produces this output according to standard error behavior.

Supported Configurations

You can export and import the following between NI-DCPower sessions:

  • Attribute configurations
  • Advanced sequences

Support for Sequences

You must set the session source mode to Sequence in order to configure or export and import advanced sequences.

spd-note-note
Note  

Exporting and importing simple sequences between sessions in Sequence source mode is unsupported.

Channel Mapping Behavior

When exporting and importing configurations between NI-DCPower sessions that were initialized with different channels, the configurations of the exporting channels are mapped to the importing channels in the order you specify in the channels input to the Initialize With Channels node for each session.

For example, if your entry for channels is 0,1 for the exporting session and 1,2 for the importing session:

  • The configuration exported from channel 0 is imported into channel 1.
  • The configuration exported from channel 1 is imported into channel 2.
spd-note-note
Note  

NI-DCPower 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.

Where This Node Can Run:

Desktop OS: Windows
