stPMU Disable PMU

Disables the PMU source operations on the channels specified in the channel list parameter. Use the return state parameter to tristate or return each channel to its previous digital state.

Note When you use the PMU nodes to source a voltage or current on your system, the voltage or current continues to be sourced on the selected channels until you reset your device or call this node. The Abort and Close nodes do not stop sourcing the voltage or current.
Note Even after using this node to disable the PMU source operations, you can still use the PMU measure voltage operations.
Note Only the PXIe-6555 and the PXIe-6556 support this node.

Inputs/Outputs

datatype_icon

session in

Instrument session obtained from the Initialize Acquisition Sessionnode, the Initialize Generation Sessionnode, or the Initialize External Calibrationnode.

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

return state

Parameter that selects, after disabling, whether to tristate the channel or to return it to its previous digital state.

Note PFI 1, PFI 2, DDC CLK OUT, and STROBE support only previous digital state. If you try to tristate a PFI channel, NI-HSDIO returns an error.
Tristate

Tristates the channel.

Previous digital state

Returns the channel to its previous digital state.

Default value: Tristate

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

Default value: 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 Sessionnode or the Initialize Generation Sessionnode.

datatype_icon

error out

Error information.

The node produces this output according to standard error behavior.

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 Commitnode, the Initiatenode, the Read Waveformnode, the Write Named Waveformnode, or the other nodes, this node will not commit your session again.
