Configure Multi Point (G Dataflow)

Last Modified: September 16, 2017

Configures the properties for multipoint measurements.

This node sets values for the Trigger Count, Sample Count, Sample Trigger, and Sample Interval properties. For continuous acquisitions, set Trigger Count or Sample Count to zero.

connector_pane_image
datatype_icon

session in

Instrument identifier from previous NI-DMM nodes.

Default: None

datatype_icon

trigger count

Number of triggers you want the DMM to receive before returning to the Idle state.

NI-DMM sets the Trigger Count property to this value.

Default: 1

datatype_icon

sample count

Number of measurements the DMM makes in each measurement sequence initiated by a trigger. NI-DMM sets the Sample Count property to this value.

Default: 1

datatype_icon

sample trigger

Sample trigger source to use.

NI-DMM sets the Sample Trigger property to this value.

Default: Immediate

datatype_icon

sample interval

Amount of time the DMM waits between measurement cycles.

NI-DMM sets the Sample Interval property to this value. Use a sample interval to add settling time between measurement cycles or to decrease the measurement rate. A sample interval only applies when the sample trigger is set to Interval.

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

Instrument identifier for subsequent NI-DMM nodes.

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

Hardware Support:

The PCI/PXI-4065, PXI-4070, PXI-4071, and PXI-4072 use the value specified in sample interval as additional delay. The default value (-1) ensures that the DMM settles for the recommended time. This is the same as using an Immediate trigger.

The PXIe-4080, PXIe-4081, and PXIe-4082 do not use the sample interval parameter.
