Insert SubSequence Call Step using TS API

[SercoSteve]

We are creating a LabVIEW application that generates TestStand Test Sequences, using the TS API.  I am attempting to write a SubVI that creates a TestStand Sub Sequence Call step.  The problem I am having is that although I can create the SubSequence call without problem I cannot seem to find a way of specifying the arguments for the parameters to pass to the sub sequence that is called by the SubSequence call step.

We are using TS 3.1 and LV 7.1

Has anyone got any ideas?

Regards

Hi Steve,

I have done this with C# take a look to this code

static bool DoSequenceCallStep( XmlNode nodeStep, Step step, SequenceFile seqFile, Engine engine)
{
XmlAttributeCollection attrColl;
attrColl = nodeStep.Attributes; XmlAttribute attrID = (XmlAttribute)attrColl.GetNamedItem("ID");
XmlAttribute attrName = (XmlAttribute)attrColl.GetNamedItem("Name");
XmlAttribute attrMin = (XmlAttribute)attrColl.GetNamedItem("Min");
XmlAttribute attrSoll = (XmlAttribute)attrColl.GetNamedItem("Soll");
XmlAttribute attrMax = (XmlAttribute)attrColl.GetNamedItem("Max");
XmlAttribute attrDoReport = (XmlAttribute)attrColl.GetNamedItem("DoReport");
XmlAttribute attrSeqName = (XmlAttribute)attrColl.GetNamedItem("SeqName"); String strSeqName = attrSeqName.Value; Sequence sequence;
// sequenz neu erstellen falls sie noch nicht existiert
if (!seqFile.SequenceNameExists(strSeqName))
{
sequence = engine.NewSequence();
sequence.Name = attrSeqName.Value;
PropertyObject pObj = sequence.Parameters;
pObj.NewSubProperty("dblMin", PropertyValueTypes.PropValType_Number, false, "", 0);
pObj.NewSubProperty("dblSoll", PropertyValueTypes.PropValType_Number, false, "", 0);
pObj.NewSubProperty("dblMax", PropertyValueTypes.PropValType_Number, false, "", 0);
seqFile.InsertSequence(sequence);
}
else
{
sequence = seqFile.GetSequenceByName(strSeqName);
} SequenceCallModule objModule = (SequenceCallModule)step.Module;
objModule.UseCurrentFile = true;
objModule.SequenceName = strSeqName;
objModule.UseSequenceParameterPrototype = false;
objModule.LoadParametersFromSequence(sequence); SequenceCallParameters Parameters = objModule.Parameters;
SequenceCallParameter Parameter;
String strValueExpr;

Parameter = Parameters[0];

if (attrMin.Value.Length == 0)
Parameter.UseDefaultValue = true;
else
{
strValueExpr = attrMin.Value.Replace(",", ".");
Parameter.ValueExpr = strValueExpr;
}

Parameter = Parameters[1];

if (attrSoll.Value.Length == 0)
Parameter.UseDefaultValue = true;
else
{
strValueExpr = attrSoll.Value.Replace(",", ".");
Parameter.ValueExpr = strValueExpr;
}

Parameter = Parameters[2];

if (attrMax.Value.Length == 0)
Parameter.UseDefaultValue = true;
else
{
strValueExpr = attrMax.Value.Replace(",", ".");
Parameter.ValueExpr = strValueExpr;
}
// Do Report
bool bDoReport = true;
if (attrDoReport.Value.Length != 0)
{
String strHelp = attrDoReport.Value;
if(strHelp.CompareTo("0") == 0)
{
bDoReport = false;
}
else
{
bDoReport = true;
}
}
step.RecordResult = bDoReport; // SeqName
step.Name = attrName.Value;
return true;
}

Do not care about the XML stuff from the i get the values !
I think this code snipped could be useful your you because the procedure in LV is the same

Cheers Juergen

Exactly what I needed.

Hi Juergen,

What is the namespace that I need to include for the code in C# for calling the TS APIs to add new sequences in TestStand 4.0 dynamically?

Saranya.

Hi Saranya,

Good question, you have to implement a second component the AdapterApi.

1. Component: (In German Called: Verweis)
NationalInstruments.TestStand.Interop.API
Location: C:\WINDOWS\assembly\GAC_MSIL\NationalInstruments.TestStand.Interop.API\4.0.0.326__ad9244eb3b825cd8\NationalInstruments.TestStand.Interop.API.dll

2. Component:
NationalInstruments.TestStand.Interop.AdapterAPI
Location: C:\WINDOWS\assembly\GAC_MSIL\NationalInstruments.TestStand.Interop.AdapterAPI\4.0.0.326__ad9244eb3b825cd8\NationalInstruments.TestStand.Interop.AdapterAPI.dll

Hi, is there a way to do that  using C++ language?

Thank you for  your help

Hello,

How to do this using Labview.

I have inserted parameter into the TS.SData.ActualArgs.

But I am getting error in the module tab.

17500 

Error Occured while trying to refresh edit panel SeqEdit.o

operation Failed.

(Continuous error pop up.have to close editor)

But I can see that parameter inserted in the TS.SData.ActualArgs.
