Configure Output Function (G Dataflow)

Last Modified: January 29, 2018

Configures the function that the device attempts to generate for the specified channel.

connector_pane_image
datatype_icon

session in

Instrument session obtained from the Initialize With Channels node.

datatype_icon

channel name

Output channel(s) to which to apply this configuration value.

Channel Name Syntax

You can input the channel name with the following options:
  • A single channel, such a 0
  • A list of channels, such as 0,1 or 3,2,1,0.
  • A range of channels, such as 0-7 or 0:7.

Note  

The order of channels in a list is important. NI-DCPower performs configurations of multiple output channels in the order the channels occur in the list.

datatype_icon

output function

Function to generate for the specified channel(s).

Name Value Description
DC Voltage 1006 Sets the output function to DC voltage.
DC Current 1007 Sets the output function to DC current.
Pulse Voltage 1049 Sets the output function to pulse voltage.
Pulse Current 1050 Sets the output function to pulse current.

Default: DC Voltage (1006)

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

Handle used to identify the session in all subsequent NI-DCPower node calls.

datatype_icon

error out

Error information.

The node produces this output according to standard error behavior.

DC Voltage

When DC Voltage is selected, the device generates the desired voltage level on the output as long as the output current is below the current limit. The following nodes can be used to configure the channel when DC Voltage is selected:

  • Configure Voltage Level
  • Configure Current Limit
  • Configure Voltage Level Range
  • Configure Current Limit Range

DC Current

When DC Current is selected, the device generates the desired current level on the output as long as the output voltage is below the voltage limit. The following nodes can be used to configure the channel when DC Current is selected:

  • Configure Current Level
  • Configure Voltage Limit
  • Configure Current Level Range
  • Configure Voltage Limit Range

Pulse Voltage

When Pulse Voltage is selected, the device generates pulses at the desired pulse voltage levels on the output as long as the output current is below the pulse current limit. The following nodes can be used to configure the channel when Pulse Voltage is selected:

  • Configure Pulse Voltage Level
  • Configure Pulse Bias Voltage Level
  • Configure Pulse Current Limit
  • Configure Pulse Bias Current Limit
  • Configure Pulse Voltage Level Range
  • Configure Pulse Current Limit Range

Pulse Current

When Pulse Current is selected, the device generates pulses at the desired pulse current levels on the output as long as the output voltage is below the pulse voltage limit. The following nodes can be used to configure the channel when Pulse Current is selected:

  • Configure Pulse Current Level
  • Configure Pulse Bias Current Level
  • Configure Pulse Voltage Limit
  • Configure Pulse Bias Voltage Limit
  • Configure Pulse Current Level Range
  • Configure Pulse Voltage Limit Range
