IviSwtch Reset Interchange Check (G Dataflow)

Version:
    Last Modified: October 23, 2017

    Determines if each test module completely configures the state of each instrument it uses. By calling this node at the beginning of a test module, you can determine whether the test module has dependencies on the operation of previously executed test modules. After you call this node, the interchangeability checking algorithms in the specific driver ignore all previous configuration operations.

    instrument handle

    The instrument handle that you obtain from the IviSwtch Initialize Node. The handle identifies a particular instrument session.

    Default: None

    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

    instrument handle out

    The instrument handle that you obtain from the IviSwtch Initialize Node. The handle identifies a particular instrument session.

    Default: None

    datatype_icon

    error out

    Error information.

    The node produces this output according to standard error behavior.

    Test Systems with Multiple Test Modules

    When developing a complex test system that consists of multiple test modules, it is generally a good idea to design the test modules so that they can run in any order. To do so requires ensuring that each test module completely configures the state of each instrument it uses. If a particular test module does not completely configure the state of an instrument, the state of the instrument depends on the configuration from a previously executed test module. If you execute the test modules in a different order, the behavior of the instrument and therefore the entire test module is likely to change. This change in behavior is generally instrument specific and represents an interchangeability problem.

    Clearing Interchangeability Warnings

    This node does not clear the interchangeability warnings from the list of previously recorded interchangeability warnings. If you want to guarantee that the IviSwtch Get Next Interchange Warning Node only returns those interchangeability warnings that are generated after calling this node, you must clear the list of interchangeability warnings. You can clear the interchangeability warnings list by repeatedly calling the IviSwtch Get Next Interchange Warning Node until no more interchangeability warnings are returned. If you are not interested in the content of those warnings, you can call the IviSwtch Clear Interchange Warnings Node.

    Where This Node Can Run:

    Desktop OS: Windows

    FPGA: Not supported

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