IviDCPwr Configure Trigger Source [TRG] (G Dataflow)

Version:
    Last Modified: October 24, 2017

    Configures the trigger source to which the power supply responds after you call IviDCPwr Initiate [TRG].

    When the power supply receives a trigger signal on the source you specify, it changes its current and voltage outputs.

    You configure the triggered current and voltage outputs with the IviDCPwr Configure Triggered Current Limit [TRG] and IviDCPwr Configure Triggered Voltage Level [TRG] VIs.

    This VI is part of the IviDCPwrTrigger [TRG] extension group.

    instrument handle

    The instrument handle that you obtain from the IviDCPwr Initialize or IviDCPwr Initialize With Options node. The handle identifies a particular instrument session. Default Value: None

    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

    channel name ("CHANNEL1")

    Specifies the virtual channel name that you assign to the instrument in the Configuration Utility. Users who want to achieve interchangeability should use a virtual channel name. The virtual channel name should be sufficiently specific to the test system such that it is unlikely to conflict with a physical channel name. Virtual channel names are aliases for instrument-specific channel strings. The instrument-specific channel strings can differ from one instrument to another. Virtual channel names allow you to use and swap instruments without having to change the channel names in your source code. You assign a virtual channel name to an instrument-specific channel through the Configuration Utility. This control accepts virtual channel names you have assigned to the specific instrument you are using. It also accepts the instrument-specific channel names.

    Default: "CHANNEL1"

    source (Immediate)

    Pass the trigger source to which you want the power supply to respond. The driver sets the IviDCPwr>>Trigger Subsystem>>Trigger Source [TRG] property to this value.
