Programatically create multiple limits test using CVI Adaptor

[kellymidge10101]

HI,

I'm using a CVI Adaptor as a multiple limits test step type.  The module called sets the no of tests, limits and data source and that all works as expected.  The next step would be to add the limits (set in Step.Results.Measurement[measNo].Limits.Hi etc) and change the name associated with each Measurement in the Measurement container.  I'm having trouble figuring out how to access the flags of these values to ensure they are set AsLimit and IncludeInReport.  I've seen some LV examples but can't find a CVI example.

Any pointers?

Many Thanks,

Steve

Hi Steve,

You should be able to access the limits like normal through the Result.Measurement[x].Limits container, but you'll have to get at the underlying PropertyObject to set the name of the Measurement.

Something like this in CVI:

int InsertTest(CAObjHandle *Step, const char *name, long limitLow, long limitHigh)
{
	CAObjHandle mMeasurements;
	CAObjHandle mMeasurement;
	tsErrChk(TS_PropertyGetPropertyObject (*Step, &errorInfo, "Result.Measurement", 0, &mMeasurements));
	tsErrChk(TS_PropertyInsertElements (mMeasurements, &errorInfo, 0, 1, 0));
	
	//Set the name of the underlying PropertyObject of the measurement
	tsErrChk(TS_PropertyGetPropertyObject (*Step, &errorInfo, "Result.Measurement[0]", 0, &mMeasurement));
	tsErrChk(TS_PropertySetProperty (mMeasurement, &errorInfo, TS_PropertyName, CAVT_CSTRING, name));	

	//Set Comparison mode
	tsErrChk(TS_PropertySetValString (*Step, &errorInfo, "Result.Measurement[0].Comp", 0, "GELE"));
	
	//Set Limits
	tsErrChk(TS_PropertySetValNumber (*Step, &errorInfo, "Result.Measurement[0].Limits.High", 0, limitHigh ));			 
	tsErrChk(TS_PropertySetValNumber (*Step, &errorInfo, "Result.Measurement[0].Limits.Low", 0, limitLow ));

	Error:
		CA_DiscardObjHandle (mMeasurement);
                CA_DiscardObjHandle (mMeasurements); 
		return error;
}

Edit:you'll have to use the TS_PropertySetFlags function to set the appropriate flags

Hope this helps!

Trent,

Thanks for that, it worked as far as getting the measurement name in the report but I still can't get the upper and lower limits and the measurement type into the report.  I've assumed it's the Flag settings so I use TS_PropertySetFlags on the Step object with the search string as "Result.Measurement[0].Limits.High".  This doesn't work, however.  Here is a snippet (it's in a loop):

sprintf (cMeasLookUpString,"Step.Result.Measurement[%i].Limits.Low",iInsMeasLoop);
  TS_PropertySetValNumber (sequenceContext, &errInfo, cMeasLookUpString, 0,dLowerLimit[iInsMeasLoop]);
   TS_PropertyGetPropertyObject (sequenceContext, &errInfo,cMeasLookUpString, 0,&hMeasObject);
    TS_PropertySetFlags(hMeasObject,&errInfo,"",0,0x3000); 

Any further help would be awesome!  Thanks,

Steve

Try setting the flag on just the "Limits" container - it should apply recursively. Also, are you trying to set a combination of flags? If not, you should only need to set 0x1000 for the Limits container. Here's an updated version of my snippet that creates a test with limits visible in the report:

int InsertTest(CAObjHandle *Step, const char *name, long limitLow, long limitHigh)
{
	double mNumMeas = 0;
	CAObjHandle mMeasurements = 0;
	CAObjHandle mMeasurement = 0;
	CAObjHandle mNumericArray = 0;
	CAObjHandle mDataSourceArray = 0;

	tsErrChk(TS_PropertyGetPropertyObject (*Step, &errorInfo, "Result.Measurement", 0, &mMeasurements));
	tsErrChk(TS_PropertyInsertElements (mMeasurements, &errorInfo, 0, 1, 0));
	
	//Set the name of the underlying PropertyObject of the measurement
	tsErrChk(TS_PropertyGetPropertyObject (*Step, &errorInfo, "Result.Measurement[0]", 0, &mMeasurement));
	tsErrChk(TS_PropertySetProperty (mMeasurement, &errorInfo, TS_PropertyName, CAVT_CSTRING, name));	

	//Set Comparison mode
	tsErrChk(TS_PropertySetValString (*Step, &errorInfo, "Result.Measurement[0].Comp", 0, "GELE"));
	
	//Set Limits & isLimit flag
	tsErrChk(TS_PropertySetFlags(*Step, &errorInfo,"Result.Measurement[0].Limits",0,0x1000));
	tsErrChk(TS_PropertySetValNumber (*Step, &errorInfo, "Result.Measurement[0].Limits.High", 0, limitHigh ));			 
	tsErrChk(TS_PropertySetValNumber (*Step, &errorInfo, "Result.Measurement[0].Limits.Low", 0, limitLow ));
	
	//Add to NumericArray and DataSourceArray
	tsErrChk(TS_PropertyGetPropertyObject (*Step, &errorInfo, "NumericArray", 0, &mNumericArray));
	tsErrChk(TS_PropertyGetPropertyObject (*Step, &errorInfo, "DataSourceArray", 0, &mDataSourceArray));
	tsErrChk(TS_PropertyInsertElements (mNumericArray, &errorInfo, 0, 1, 0));
	tsErrChk(TS_PropertyInsertElements (mDataSourceArray, &errorInfo, 0, 1, 0));

	//Add to ExpectedNumMeas
	tsErrChk(TS_PropertyGetValNumber (*Step, &errorInfo, "ExpectedNumMeas", 0, &mNumMeas));
	tsErrChk(TS_PropertySetValNumber (*Step, &errorInfo, "ExpectedNumMeas", 0, mNumMeas+1));
	
	Error:
		CA_DiscardObjHandle (mMeasurements);
		CA_DiscardObjHandle (mMeasurement);
		CA_DiscardObjHandle (mNumericArray);
		CA_DiscardObjHandle (mDataSourceArray);
		return error;
}

Hope this helps!

Hi Trent,

That looks like what I need!  I've been busy elsewhere but I'll try that later today.....

Thanks for your help,
