Configure Voltage Limit (G Dataflow)

Version:
    Last Modified: March 3, 2017

    Configures the voltage that the output should not exceed when generating the desired current level for the specified channel(s).

    The voltage limit setting is applicable only if the output function of the channel is set to DC Current. The channel must be enabled for the specified voltage limit to take effect.

    datatype_icon

    session in

    Instrument session obtained from the Initialize With Channels node.

    datatype_icon

    channel name

    Output channel(s) to which to apply this configuration value.

    Channel Name Syntax

    You can input the channel name with the following options:
    • A single channel, such a 0
    • A list of channels, such as 0,1 or 3,2,1,0.
    • A range of channels, such as 0-7 or 0:7.

    Note  

    The order of channels in a list is important. NI-DCPower performs configurations of multiple output channels in the order the channels occur in the list.

    datatype_icon

    voltage limit

    Voltage, in volts, that the output should not exceed when generating the desired current level for the specified channel(s).

    The limit is specified as a positive value, but symmetric positive and negative limits are enforced simultaneously.

    The valid values for this parameter are defined by the voltage limit range that is configured using the Configure Voltage Limit Range 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

    session out

    Handle used to identify the session in all subsequent NI-DCPower node calls.

    datatype_icon

    error out

    Error information.

    The node produces this output according to standard error behavior.

    Enabling the Output Channel

    Refer to the Configure Output Enabled node for more information about enabling the output channel.

    Setting the Output Function of the Channel

    Use the Configure Output Function node to set the output function of the channel. The voltage limit configured with the Configure Voltage Limit node is applicable only if the channel is set to the DC Current output function.

    Where This Node Can Run:

    Desktop OS: Windows

    FPGA: Not supported
