Sets or gets properties of the device.

connector_pane_image
datatype_icon

nidcpower in

Instrument session passed from preceding node.

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

nidcpower out

Instrument session passed to the next node.

datatype_icon

error out

Error information.

The node produces this output according to standard error behavior.

Multichannel Device Considerations

For multichannel devices, to access a channel-based property in a multichannel session, you must wire an Active Channel of an NI-DCPower property node. The Active Channel is listed first in the property node.

You can specify multiple channels by using a channel list or a channel range. A channel list is a comma (,) separated sequence of channel names (e.g. 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 (e.g. 0-2 specifies channels 0, 1, and 2). In the Running state, multiple output channel configurations are performed sequentially based on the order specified in Active Channel.

Single-Channel Device Considerations

If the device only has one channel, you do not need to wire an Active Channel to access the channel-based properties. To access a device-based property, do not wire an Active Channel, or wire an empty string ("").
