stPMU Source Voltage (G Dataflow)

Version:
Last Modified: September 27, 2017

Enables the PMU capabilities on the channels specified in the channel list parameter and sources the voltage specified in the voltage level parameter.

Only the PXIe-6555 and the PXIe-6556 support this node.

session in

Instrument session obtained from the Initialize Acquisition Session node, the Initialize Generation Session node, or the Initialize External Calibration node.

channel list

The channels you want to configure.

Specify multiple channels by using a channel list or a channel range. A channel list is a comma (,) separated sequence of channel names (for example, 0,2 specifies channels 0 and 2). A channel range is a lower bound channel followed by a hyphen (-) or colon (:) followed by an upper bound channel (for example, 0-2 specifies channels 0, 1, and 2).

Use PFI1 or PFI2 to specify a valid PFI channel. Use DDC_CLKOUT or STROBE to specify a valid clocking terminal. If you configure multiple channels with this parameter, all those channels have the same settings. Selecting no channels for this parameter returns an error.

datatype_icon

voltage level

The voltage level, in volts (V), for the output generation channel(s). Valid values range from -2 V to +7 V.

datatype_icon

sense (local)

Parameter that selects between local or remote sensing on the specified channel(s).

Name Value Description
local 88 Local sensing of voltages. This value is measured on the DDC connector.
remote 89 Remote sensing of voltages. This value is measured on the Remote Sense connector.

Default: local

datatype_icon

current range

The current range, in amps (A), used in the ensuing current measurement on the specified channel(s).

The PXIe-6555/6556 supports the following eight current range options:

  • 32 mA
  • 8 mA
  • 2 mA
  • 512 μA
  • 128 μA
  • 32 μA
  • 8 μA
  • 2 μA

If you choose a range other than one of these options, NI-HSDIO coerces the value up to the nearest range. NI-HSDIO also returns an error if you enter a value above 32 mA.

The default value is 0, but NI-HSDIO returns an error if you select a value less than or equal to 0.

Tightening your current range increases your accuracy.

Default: 0

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 that identifies the session in all subsequent node calls.

The session out parameter is obtained from the Initialize Acquisition Session node or the Initialize Generation Session node.

error out

Error information.

The node produces this output according to standard error behavior.

Committing your session

If you have not yet committed your session, calling this node implicitly commits your session. If you have already committed your session by calling a node such as the Commit node, the Initiate node, the Read Waveform node, the Write Named Waveform node, or the other nodes, this node will not commit your session again.

Where This Node Can Run:

Desktop OS: Windows

FPGA: Not supported

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