Hi Doug.
I'm sorry for the delay.
Here's how I solved the problem: I changed from CVI module to DLL module.
Here's a sample of my code:
//I changed from CVIModuleGetParameters() and CVIParametersGetItem() to TS_DllModuleGetParameters() and TS_DllParametersGetItem and now it works fine.
//seqContextCVI = ThisContext reference object
void __declspec(dllexport) __stdcall GetControlarParameters(CAObjHandle seqContext)
    int error = 0;
    ErrMsg errMsg = {'\0'};
    ERRORINFO errorInfo;
    char strItemLabel2[1024] = "";
    CAObjHandle step = 0;
    CAObjHandle seqFile = 0;
    CAObjHandle module = 0;
    CAObjHandle parameters = 0;
    CAObjHandle parameter = 0;
    tsErrChk(TS_SeqContextGetStep (seqContext, &errorInfo, &step));
    tsErrChk(TS_StepGetModule(step, &errorInfo, &module));
    tsErrChk(TS_DllModuleGetParameters (module, &errorInfo, &parameters));
    tsErrChk(TS_DllParametersGetItem (parameters, &errorInfo, CA_VariantInt(1), &parameter));
    sprintf(strItemLabel2, "\"%s\"", "TEST");
    tsErrChk(TS_CommonCParameterSetValueExpr(parameter​, &errorInfo, strItemLabel2));
    // NOTE: After making an edit to a step you need to mark the file as modified by
    // incrementing the file's change count. This is also necessary for the change to show
    // up in the sequence editor imediately.
    tsErrChk(TS_SeqContextGetSequenceFile (seqContext, &errorInfo, seqFile));
    tsErrChk(TS_SeqFileIncChangeCount(seqFile, &errorInfo));
Error: 
    CA_DiscardObjHandle(step);
    CA_DiscardObjHandle(seqFile);
    CA_DiscardObjHandle(module);
    CA_DiscardObjHandle(parameters);
    CA_DiscardObjHandle(parameter);
    // If an error occurred, set the error flag to cause a run-time error in TestStand.
    if (error < 0)
        TS_SetStepError(seqContext, error, errMsg);
Thank you for all the help.
My best regards.
