Measure Multiple (G Dataflow)

Last Modified: January 23, 2018

Returns arrays of the measured voltage and current values on the specified output channel(s).

Each call to this node blocks other node calls until the hardware returns the measurements.

session in

Instrument session obtained from the Initialize With Channels node. If instrument handle does not receive a value, then measurements are taken for all output channels.

datatype_icon

channel name

Output channels to measure.

If the input does not receive a value, then measurements are taken for all output channels.

Channel Name Syntax

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

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

voltage measurements

Array of voltage measurements.

The measurements in the array are returned in the same order as the channels specified in channel name.

datatype_icon

current measurements

Array of current measurements.

The measurements in the array are returned in the same order as the channels specified in channel name.

datatype_icon

error out

Error information.

The node produces this output according to standard error behavior.

Where This Node Can Run:

Desktop OS: Windows

FPGA: Not supported

Web Server: Not supported in VIs that run in a web application
