IviACPwr Configure Voltage Protection [VP] (G Dataflow)

Version:
    Last Modified: October 24, 2017

    Configures voltage protection. When the Over Volt Protection Enabled input and/or Under Volt Protection Enabled input is True, the AC power source enters the voltage protection state (tripped) and disables the output when the output voltage is below the value in the Under Voltage Limit control or above the value in the Over Voltage Limit control. When the Over Volt Protection Enabled input and/or Under Volt Protection Enabled input is False, the corresponding limit does not affect the instrument's behavior and under and/or over voltage protection is disabled.

    Over Voltage Limit

    Specifies the over voltage protection limit. The driver uses this value to set the IviACPwr Over Voltage Protection Limit [VP] property. Default Value: None

    datatype_icon

    Over Volt Protection Enabled (True)

    Enables or disables the over voltage protection. The driver uses this value to set IviACPwr Over Voltage Protection Enabled [VP] property. Valid Values: TRUE - Enables the over voltage protection. FALSE - Disables the over voltage protection. Default Value: True

    instrument handle

    The instrument handle that you obtain from IviACPwr Initialize or IviACPwr Initialize With Options. The handle identifies a particular instrument session.

    Default: 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

    Phase Name ("")

    Specifies the name of the output phase to configure. Pass the virtual output phase name that you assign to the instrument in the IVI Configuration utility. Users who want to achieve interchangeability should use a virtual output phase name. The virtual output phase name should be sufficiently specific to the test system such that it is unlikely to conflict with a physical output phase name. Virtual output phase names are aliases for instrument-specific output phase strings, which can differ from one instrument to another. With virtual output phase names, you can use and swap instruments without having to change the output phase names in your source code. Assign a virtual output phase name to an instrument-specific output phase through the IVI Configuration utility. This control accepts virtual output phase names you have assigned to the specific instrument you are using and also accepts the instrument-specific output phase names. Default Value: "" Note: You can specify the output phase name as a string variable or as a literal enclosed in double quotes.

    datatype_icon

    Under Volt Protection Enabled (True)

    Enables or disables the under voltage protection. The driver uses this value to set IviACPwr Under Voltage Protection Enabled [VP] property. Valid Values: TRUE - Enables the under voltage protection. FALSE - Disables the under voltage protection. Default Value: True

    datatype_icon

    Under Voltage Limit

    Specifies the under voltage protection limit. The driver uses this value to set IviACPwr Under Voltage Protection Limit [VP] property. Default Value: None

    datatype_icon

    instrument handle out

    The instrument handle that you obtain from IviACPwr Initialize or IviACPwr Initialize With Options.

    error out

    Error information.

    The node produces this output according to standard error behavior.

    Where This Node Can Run:

    Desktop OS: Windows

    FPGA: Not supported

    Web Server: Not supported in VIs that run in a web application
