niDMM_ResetInterchangeCheck

ViStatus = niDMM_ResetInterchangeCheck(ViSession Instrument_Handle)

Purpose

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. You can use this function to test for such cases. After you call this function, the interchangeability checking algorithms in NI-DMM ignore all previous configuration operations. By calling this function at the beginning of a test module, you can determine whether the test module has dependencies on the operation of previously executed test modules.

This function does not clear the interchangeability warnings from the list of previously recorded interchangeability warnings. If you want to guarantee that niDMM_GetNextInterchangeWarning only returns those interchangeability warnings that are generated after calling this function, you must clear the list of interchangeability warnings. You can clear the interchangeability warnings list by repeatedly calling niDMM_GetNextInterchangeWarning until no more interchangeability warnings are returned. If you are not interested in the content of those warnings, you can call niDMM_ClearInterchangeWarnings.

Parameters

Input
Name	Type	Description
Instrument_Handle	ViSession	Identifies a particular instrument session. You obtain the Instrument_Handle parameter from niDMM_init or niDMM_InitWithOptions. The default is None.

Return Value

Name	Type	Description
Status	ViStatus	Reports the Status of this operation. To obtain a text description of the status code, call niDMM_error_message. To obtain additional information concerning the error condition, use niDMM_GetError.
