Configure Voltage Level (G Dataflow)

Last Modified: January 29, 2018

Configures the voltage level that the device attempts to generate for the specified channel(s).

The voltage level setting is applicable only if the output function of the channel is set to DC Voltage. The channel must be enabled for the specified voltage level to take effect.

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

voltage level

Voltage level, in volts, for the output channel generation.

The valid values for this parameter are defined by the voltage level range that is selected using the Configure Voltage Level Range node.

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.

error out

Error information.

The node produces this output according to standard error behavior.

Enabling the Output Channel

Refer to the Configure Output Enabled node for more information about enabling the output channel.

Setting the Output Function of the Channel

Use the Configure Output Function node to set the output function of the channel. The voltage level setting configured with the Configure Voltage Level node is applicable only if the channel is set to the DC Voltage output function.

Current Limit Considerations

The device actively regulates the voltage at the specified level unless doing so causes a current drop greater than the current limit across the channels' output terminals.
