stPMU External Force Control (G Dataflow)

Version:
    Last Modified: September 27, 2017

    Connects or disconnects the specified channels to or from the external force terminal (either on the AUX I/O connector or the remote sense connector on the device front panel, depending on the value of the connectors parameter).

    This nodes does not force a voltage or current by itself; it only connects NI-HSDIO to an external device.

    Only the PXIe-6555 and PXIe-6556 support this nodes

    datatype_icon

    session in

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

    datatype_icon

    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

    action

    Parameter that selects whether to connect or disconnect a channel or channels from the EXTERNAL FORCE pin.

    Note  

    On the PXIe-6556, selecting Disconnect disconnects both the AUX I/O and Remote Sense connectors regardless of which is connected currently.

    Name Description
    Connect

    Connects the channel to the EXTERNAL FORCE pin.

    Disconnect

    Disconnects the channel from the EXTERNAL FORCE pin.

    datatype_icon

    connector

    Parameter that selects whether to access the PMU pins on the AUX I/O connector or the REMOTE SENSE connector.

    Name Description
    AUX I/O

    Accesses the PMU pins on the AUX I/O connector. This is the default value.

    Remote Sense

    Accesses the PMU pins on the REMOTE SENSE connector.

    Using this parameter with the PXIe-6555/6556

    This parameter is valid only on the PXIe-6556, which has both the AUX I/O and REMOTE SENSE connectors. If you are operating an PXIe-6555, you must select Remote Sense because the PXIe-6555 does not have an AUX I/O connector. If you select AUX I/O while using an PXIe-6555, NI-HSDIO returns an error.

    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.

    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
