Configure Pulse Current Limit (G Dataflow)

Last Modified: August 30, 2018

Configures the pulse current limit that the output must not exceed when generating the desired pulse voltage level for the specified channel(s).

The pulse current limit setting is only applicable if the output function of the channel is set to Pulse Voltage. The channel must be enabled for the specified current limit 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.

pulse current limit

Pulse current limit, in amps, that the output must not exceed when generating the desired pulse voltage level for the specified channel(s).

The limit is specified as a positive value, but symmetric positive and negative limits are enforced simultaneously.

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

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.

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 pulse current limit configured with the Configure Pulse Current Limit node is applicable only if the channel is set to the Pulse Voltage output function.
