Executing 3 FM's in a sequence

Hi all,
I need to execute 3 FM's(eg create ,save and commit) in SE37.How do i do this?

To execute all the three function module in sequence
goto->se37>Test>test sequences--> enter the function module name in sequence
Execute first one and paas the import parameters to first one and press F8.
Go back now i.e. press F3 and pass the import parameters to second one and execute it F8.
And so on....

Is it possible to create a distribution kit or executable file out of a Teststand sequence file that uses CVI standard prototypes?

How can i create an executable file or distribution kit of a sequence file in teststand?. I'm using CVI standard prototypes.

If you want to distribute your sequence files to other machines, there are a few things you must consider.
1. Create a TestStand Run-Time Engine installer. You can do this by selecting Tools>>Run Engine Installation Wizard.
2. Distribute your Operator Interface.
3. Distrbute your code modules (in your case CVI) and sequences.
We do not have a tool similar to that of Assemble VIs for Distribution for CVI. You will need to ensure that all of your code is copied to the target machine and that TestStand is able to resolve the paths for where these files are located (i.e. Configure>>Search Directories).
PLEASE REFER TO THE CHAPTER IN THE TESTSTAND USER MANUAL TITLED "DISTRIBUING TESTSTAND".

How to execute a frame of a flat sequence structure for a specified amount of time?

Hello,
I have a timed loop measuring a resistance value every 2 seconds. I would like to have this timed loop execute for a specified amount of time (e.g. 5 minutes). The timed loop itself is placed within a flat sequence structure so I am concerned that the measurement will be taken once and the next frame will begin to execute, without waiting 2 seconds for a successive reading (and not looping for, say, 5 minutes).
In other words, is it possible to have a frame of a flat sequence structure execute for a specified amount of time before moving onto the next frame?
Thanks for your assistance!
JFK_Aero
Solved!
Go to Solution.

All code in one sequence frame must complete before the next frame can execute. So as long as your timed loop is setup correctly, the next frame cannot run until your 5 minutes is up (N = 5 minutes/2 seconds/measurement = 150 measurements).
There are only two ways to tell somebody thanks: Kudos and Marked Solutions

Test sequences not working in standard prototype adaptor with Execute Steps in process

Test sequences not working in standard prototype adaptor with "Execute Steps in process" but the sequences works in "Execute steps in an External instance of CVI"(Debug mode). Pl help with solution

Sharanu,
Thanks for contacting National Instruments. It would help us out a lot if you could specify exactly what is not working. Will the sequence just not run? Is it giving you an error message? Or what exactly does not work about it? The initial thing that I could think of that would make it not work in External Instance but not using the RunTime Engine is that you might be missing a support library when trying to run it in this configuration. If you click on the "Configure Auto-Loading of Support Libraries Needed for Linking .objs and .libs" button, you can make sure that all the support libraries you might be using are added in this list (you can add them using the "Add Other Libraries..." button). If this does not fix your problem, then let us know a litt
le more about what is going on and we can help you from there. Thanks.

How to execute a sequence without using an User Interface

Hi,
I have programatically generated a TestStand Sequence File. I used C# and the TestStand API. I opened the .seq file in the default TestStand User Interface and the Sequence File runs perfectly.
However, when I created a NewExecution using the Engine object created in the porgram, it seems that the sequence never starts execution. Please look at the following code snippet:
// TSStep and TSSequence was created before
TSSequence.InsertStep(TSStep, 0, StepGroups.StepGroup_Main); SequenceFile TSSequenceFile = TSEngine.NewSequenceFile();
TSSequenceFile.InsertSequenceEx(0, TSSequence);
TSSequenceFile.Save("SeqGen.seq"); Execution TSExecution = TSEngine.NewExecution(TSSequenceFile, "Seq_0", null, false, ExecutionTypeMask.ExecTypeMask_Normal, System.Type.Missing, System.Type.Missing, System.Type.Missing);while (TSSequenceFile.IsExecuting == true) ; // this flag never changes to false
TSEngine.ReleaseSequenceFileEx(TSSequenceFile, 0);
I know the sequence is not being executed because a COM Server (written as a Local Server in a .EXE) should start when the step within the sequence be executed.
Any ideas why the sequence is not executing properly ?
PacSoft

Hi Pacsoft,
Check out this example,
I posted it in a former thread.
Note: Also downloaded the .seq from the former thread! NEVER acept savings to Ni. -INI files !!!

Assigning a 'dynamically created sequence' value to a variable

in my procedure i am creating a sequence on the fly, i am preparing the name with some passed parameters like below
v_seq_name := 'seq_'||loadid||v_table_name;
execute immediate 'CREATE SEQUENCE '||v_seq_name||' MINVALUE 1 MAXVALUE 999999999999999999999999999 START WITH 1 increment by 1 cache 20';
and now after doing some operations i need to assign the current value of sequence to a number variable i tried following but not working
1) v_curr_value : = v_seq_name.currval ;
2) select v_seq_name||'.nextval' into v_curr_value from dual;
can you please suggest me how i can get the value in plsql block.

Having said that, your architecture is probably wrong if you are dynamically creating things in a procedure.
Why do you need to create them dynamically?

Bug jdev 10.1.3 production: sequences showing up as tables

Hello,
A bug I have found: when I generate a script to create database objects (tables & sequences) and choose in the wizard to execute against the DB connection, the sequences are showing up under the "tables" folder in the connection browser (Oracle DB). After I disconnect and re-browse, they are in the correct "sequences" folder.

How can i unload a sequence from another sequence

Hello,
i have a sequence which is running in a loop. At a specified point the sequence executes an ActiveX-call an runs "Test UUTs" with a sequence-name that is passed with a variable.
When "TestUUT" is running then first the SequenceFileLoad of the new sequence is executed and after that the Mainsequence. Thats all good up to here.
But the next time when i call the execute "Test UUTs" then the file is already in loaded and no SequenceFileLoad is running.
So my question is: What do i have to call/run that the loaded sequence is leaving the memory with SequenceFileUnload and the next time when i run "TestUUTs" is completely new loaded?
Thx for your help
Attached a screenshot of how i execute the "TestUUTs"
Attachments:
Clipboard01.jpg ‏42 KB

The thing is, i only want to execute the SequenceFileUnload when i have a new sequence name in the variable of "Execute Test UUTs".
If the sequence is loaded and executed again, then i dont want to run SequenceFileLoad again.
Thats why i want to execute an "unload"-thing somehow.
It looks like this:
string seqname= sequence1
call execute "Test UUTs" (seqname)
SequenceFileLoad(sequence1)
execute(seqname)
call execute "Test UUTs" (seqname)
//no SequenceFileLoad because its already loaded
execute(seqname)
call execute "Test UUTs" (seqname)
//no SequenceFileLoad because its already loaded
execute(seqname)
string seqname= sequence2
SequenceFileUNLoad(sequence1)
SequenceFileLoad(sequence2)
execute(seqname)
call execute "Test UUTs" (seqname)
//no SequenceFileLoad because its already loaded
execute(seqname)

Auto Start Sequence in Full UI

I am building an application and using the full user interface example as a starting point. I reviewed the example Dynamic Client Sequence File and have implemented a LabVIEW VI that selects one sequence from a list and then dynamically loads this sequence. To start this, I load a sequence file like the loadmefirst.seq in the dynamic client example and execute an entry point on this sequence to start the process by pressing the "Test UUTs" button in the user interface.
This all works fine, however, I would like to automate the loading of the "loadmefirst" sequence file and possibly the execution of the entry point lodestars on this file, especially if the user is an operator. Thus, the operator would launch the user interface application, log in and then see my menu VI. I am trying to do as much of this as possible in the model file and with the callbacks.
Any Ideas?
Thanks,
Mike

Hi Mike,
You could try passing the sequence file and sequence to run via the command line when you launch the UI.
eg. testexec.exe /run sequence sequencefile
see the reference manual Table8-6

Executing listbox items according to loop

I am making a vi in which we need to execute listbox items according to loop values defined at the begining( shown in the image attached below) , it's like that we start a loop with some values in it e.g loop(2,4,5) and loop ends with END string and all the items between loop and END we need to execute number of times the values we have defined within loop , e.g in this case since only three values are there within loop 2,4,5 so any items present between loop and END we need to execute 3 times, it could be nested loop also, we tried so many solutions but not getting how to do this, some guidance would be great help.
function of the values defined within loop bracket is that we are having instryment list defined within loop and End and we having kept one constant x with every instrument , this x ( and the values defined within loop) are different voltages, x would be replaced every time by the newq loop value until all values are not executed.
below i am attaching the sequence list image.

Like this. (However you'll need more algorithm for this to work in nested loops - you'll have to keep a track of outside loop iterations while you execute inside loops.)

Modifying Sequence directly after loading the sequences

Hi,
I'm planning to write some kind of profiler to find out which step consums the most testtime.
Therefore I'm using the Engine Callbacks SequenceFilePreStep and SequenceFilePostStep.
Whenever a Step in the sequence is executed the SequenceFilePreStep generates a timestamp and after the execution of the step the SequenceFilePostStep generates another timestamp. Both timestamps can be used to estimate how long that step was executed.
I'm using many different sequence files (e.g. one sequence fiel for feature A another sequence file for feature B and so on).
A sequence file can be called (loaded) from both the top level sequence file or from any other sequence file.
My problem is, that I don't want to modify each of the sequence files. The profiling should rather be initited automatically.
My idea is, that the process model will add the above mentioned subsequences into every sequence file that is used during execution of the testplan.
Any Idea how to implement that? As far as I have seen there is no ProcessModel callback which is called whenever a sequence file is loaded, isn't it?
Many Thanks,
Thorsten
I forgot to mention, I'm using Teststand 3.1 currently, but planning to change to 4.x
Message Edited by Tho_Wa on 10-30-2008 01:48 AM
Solved!

Hi Thorsten,
That would be a great product suggestion- StationFileLoad callback. So in the TestStand Reference Manual in Chapter 10 there is an awesome table that shows all the Engine Callbacks (table 10-1). It shows where the callbacks should be used and what not. Basically the ProcessModelPreStep and ProcessModelPostStep might be what you are looking for. You'll Notice that it states: Before the engine executes each step in any client sequence file that the process model calls, and each step in any resulting subsequence calls.
So why not just use these? The step is being passed as a parameter so you have access to it.
Let me know if you have any questions,

How to use ODI sequences ??

I have an interface which need an ODI sequence.
When I execute it the value of the sequence is always the same.
I have seen on another thread that it may pass by an agent but...
I have 2 tables (source and target) from the same connexion which don't and won't have agent.
How can I do ??
My connexion is on an Oracle 10g RDBMS and I'm using an IKM SQL Control Append.
This is not the first time I have problem with the ODI Sequence but this time I can't create an RDBMS one ...
Thanks in advance,
BM

Hi guys,
I have some questions, I am trying to create a dimension and it should use a sequence, but I am getting the same issue as you guys. I can't not generate a unique key because my sequence is the same value for all rows.
So if I really understood there are two ways to use a sequence in ODI. One is using ODI sequence (creating it inside ODI) and other is using a RDBMS sequence.
First: What I have to do to use a RDBMS sequence? (Step by step please)
Second: I can't use an IKM SQL to SQL append in my interface. This interface is pretty simple - source is a flat file target is an Oracle table, I just need to move all flat files columns to Oracle table adding a sequence. I understood that my Staging area should be different than my Target area based on posts above. I already created a new datastore to be my new staging area, but I don't know how to make an association between interface and new stage area.
Can you please provide me the easiest solution?
Thanks

Relationship between message, sequence and queue

Hello Colleagues,
I am new to PI.
I want to know the relationship between PI Message,Queue (bgrfc) and sequecne.
In sxmb_moni i could see all these enteirs in technical view, but what I am not sure how sequnce and queue works exactly.
Kindly explain or refer the related links.
-Siva

Hi,
thanks for advice, now It works correct. But I have another problem with connection between comboboxes and planning sequences (functions). Do you know any way how to take the values of variables back to comboboxes. Its opposite way.
For better understanding I execute planning sequnce and for this sequence I want to use reversible binding. I want to use in planning function (in planning sequence) one variable for characteristic "VERSION" and I want to copy from VERSION 1 to VERSION 2. So I have in combo for char. Version value 1 and I want to after execution of planning sequence change the value in combo to 2. Do you have any experience?? This is typical for copy between versions.
Thanks a lot.
Best regard.

VariableScope problem with sequence containers (SSIS 2012)

Hi,
a co-worker of mine experienced a problem with variable scopes in SSIS 2012 when copying a sequence container.
This is what he tried to do:
Create a sequence container with a data flow task and a script component
Add variable "a" with scope set to the sequence container
Add "a" to ReadOnlyVariables in the script component and assign it to a variable within PreExecute() in the script
Copy the sequence container (with DFT and SC)
Rename (or remove and add new - doesn't matter) variable "b" with scope set to the new sequence container
Change variable in ReadOnlyVariables of copied SC to "b", change it in the script as well
Now when executing the package, one of the sequence containers will always fail. Interestingly enough, it is not always the same but switches seemingly randomly. It doesn't matter if the script is written in C# or VB.
The following error is thrown:
Exception from HRESULT: 0xC0010009
   at Microsoft.SqlServer.Dts.Runtime.Wrapper.IDTSVariables100.get_Item(Object Index)
   at SC_f8fa68ce667a42d2b4b154c26831db5f.Variables.get_VarForCopySeqC()
   at SC_f8fa68ce667a42d2b4b154c26831db5f.ScriptMain.PreExecute()
   at Microsoft.SqlServer.Dts.Pipeline.ScriptComponentHost.PreExecute()
In this case, VarForCopySeqC is the variable used in the copied sequence container, but the failing one is the original sequence container.
Does anyone have an idea how to resolve this? Thanks in advance for anyone helping us out here!
Regards,
Thorsten H.

If the variable is scoped to the Sequence Container then you could leave it as is in the new Sequence Container too. Why rename it to "b" ?
Granular scoping makes the package debugging and maintenance a lot more difficult because you have to bring the component in focus to see its scoped variables. It is easier to have package-scoped variables IMHO.
