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

    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.

    datatype_icon

    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
