Abort execution

I want to abort the execution of mapping, which running currently.
Not thru killing oracle sessions
Tried with @abort_exec_request.sql, but which takes for ever and job is still running.
I have executed the map thru shell script job in unix (background). I have killed the unix jobs, stoped the OWB service.
still its loading into target. In SQL i have locked the target table explicitly, even no use...
Any one has any plan to stop the mapping.

Greetings
I share your pain. I have typically killed the UNIX process that is running the map via the Runtime User and also the UNIX process that is generated for the Target Schema owner as the map is trying to insert rows into a table.
The database MUST rollback any operations it has performed to get all objects back to a stable state. I have had to wait many times for the database to rollback after I've killed the unix processes. I have even killed the database processes but they stay in a KILLED status while the database rolls back.
We should be glad it does this to protect our data.
I have not tried the abort_exec_request.sql function.
Good luck.

Abort Execution leaves USB port open

My VI opens a USB port and then processes the data in a while loop for as long as I let it run. When I manually exit the while loop the VI closes the USB port and then stops execution. Using the start control starts the loop again and the VI runs. However if I use the abort execution button on the toolbar the VI stops without closing the USB port and the VI will not run again unless I close and reopen it. How do I avoid this problem?

So I suggest always stop the program from the front panel button.
You can hide the toolbar so that the the abort button can not be clicked.

Can I put abort execution button and Run button in GUI ?

Dear All ,
Can I put "abort execution button" and "Run button" in GUI with bigger buttons ?
Thanks.....

Hi wMw.
Aborting normally works fine for very small applications or architectures but not for anything after that. Aborting a VI can leave things in states that you don't want to be in or references open. Sometimes you do need to Abort the code though (other programming environments use Abort buttons) so I don't think we can get rid of it entirely.But try to avoid it maximum.
EDIT:why you are trying to do such a strange thing??
Thanks as kudos only

How to stop a period counter in a while loop without using abort execution%3F

I am using a NI x series 6343 andcounting pulses, but when i try to stop the counter with a boolean operator nothing happens, ihave to go and use abort execution,
Help

the stop sign does not do anything, it just stops after the timeout.
Which is exactly what you're asking it to do.
The STOP button is not a magic ABORT function. It's a simple TRUE/FALSE variable.
The way you have it set up is:
repeat
Get some data (Timeout = 10 sec)
Process the data
until STOPped
It's going to check that STOP value (is it pressed or not) ONCE, sometime during the loop. Maybe before your GET DATA, maybe during, maybe after - you don't know.
Whenever the GET DATA thing returns (after 10 sec, or after getting some data), then it willl use that value and decide to loop again, or to stop.
If you want to abort the GET DATA operation, you have to find another way.
One way is to use a shorter timeout. Do you have to track it down to 1 pulse every 10 sec? If not shorten your timeout and go from there.
Another way is to find a way to abort the operation.
Again, I'm not familiar with the EXPRESS stuff you're using, so I don't know the details. In all my 26 years of LabVIEW programming, I've never once used EXPRESS stuff.
Using the regular NIDAQ stuff, you would
INIT a task
START a task (Task ID)
repeat
READ a task (TaskID, timeout = 0.1 sec, or something)
if TIMED OUT
do nothing
else if ERROR
announce error
else
Process data
end if
until STOPPed or ERROR
CLEAR task(Task ID)
It's more complicated, but you have more control.

VI executable (.exe) without running, running continuously, abort execution and pause button

Dear All,
I want to make build an application (.exe) from a VI and I don´t want the front panel to show the running, running continuously, abort execution and pause buttons (VI Toolbar Buttons). The purpose is to make a SCADA application without the risk of accidental STOP.
Maybe the question is too trivial but I am new to LabVIEW and I don´t find the way to do it (I unchecked the "Show Abort Button", from the VI properties menuo of the Build Specifications but nothing happens).
Thank you very much
Javier

Abort execution of VI from TestSTand

I am trying to find an easy way to abort or terminate a called VI from TestStand. I am working on a system that controls machines and if something goes wrong I want a stop button that stops the VI immediately and runs a VI thats sends a stop signal to the machine.
Event seems like it could work and I tried using GetTerminationStatus but I cant get it to trigger an event. I have only tried using ValueChange on both GetTerminationStatus and Sequence Context In.
Is there a way to get a message popup to pop up and having VI:s running in the background? When the VI:s are done the message closes. If I push the button I want it to set a variable that triggers an event.

Hi Peter,
Here's a quick example of how to use the GetTerminationStatus VI.
Unfortunatlly you can't generate an event in LabVIEW directly you will have to poll the TerminationStatus.
This will detect someone pressing the Terminate button in the SequenceEditor or TestStand User Interface.
I've also setup the Terminate Button in the VI to trigger a Termination in TestStand.
Somethings to keep in mind.
The difference between Abort and Terminate, is that Terminate will still run the Cleanup Group of any sequences.
This is very useful to ensure everything shuts down correctly when something goes wrong.
Hope this helps

When TestStand ABORTs execution for some reason, still clean up should executed

I have few steps in Clean up part in my sequence, when there is any error in my main sequence and if the tester selects ABORT instead of Run clean up, then the clean up steps does not execute. I want to disable ABORT option or even when the ABORT is selected, still the cleanup steps should get executed.
Please let me know the option to do it.
Thanks

Teranet,
As the TestStand help mentiones the Abort method does not call the cleanup section, but we can use the Terminate which will stop and allow for cleanup. I would recommend using that function instead. In order to help further we would need to know more about how you are calling the Abort function currently (dialog, button, in a UI or the Sequence Editor, etc).

Stop in subvi also aborts execution of mainvi

IS there any function that allows you to stop the mainvi's execution via the subvi i.e. stop the running of the program entirely?
Thanks

There is no generic function for doing that, except the Quit LabVIEW node and it shutsdown LabVIEW completely. That will work, but like a friend of mine once said:
"You can sucessfully stop you car by running it into a tree -- but there can be unintended consequences..."
The problem is that if you quit LV in a subVI there is no orderly shutdown, execution stops immediately. And depending upon what your code is doing this can be a Very Bad Thing.
What exactly is it that you are wanting to accomplish? How is the program in question structured?

Stop/ abort execution in case when the task inside while loop can not be completed

I am using Count digital events example from LabVew. This VI is using DAQmx Read vi. If I press Stop button before this DAQ gets required amount of samples VI does not stop. I tried to change amount of samples on a fly with stop button but it did not work either.
Please help.

This is directly related to the way LV handle the data. Your question is similar to "How can I stop a For-Next loop before completion ?". The answer is : No way, except changing the loop for a while loop (ie: change the algorithm) or stop the whole vi.
Attached is an example of stopping an infinite running loop. It uses a parallel loop, with a Stop node (see how to handle the stop button in order to reset it to false at the next vi run).
If you only want to stop the DAQ, whithout halting everything else, the solution is trickier : you will have to run your DAQ loop in a dynamically loaded vi, then use the vi server functions to halt the vi if the run period is excessive. But that is worth another discussion...
Give some feedback !..

How to externally trigger the execution of TestStand with a start and abort button through a digital interface?

Hello,
I'm Currently evaluating TestStand as an alternative for an in-house developed Test Sequencer.
To start our own Test Sequencer we use a small box, connected to a DIO board. The box has a start button and an abort button. The box also has a pass, a fail and a running led.
The interface with this box is made via some digital lines of a PCI-DIO-96.
In our own Test Sequencer we have groups named Init, Run, Abort, Exit.
The Init group is executed at startup (only once). It is used to initialize all the HW and SW. -> I guess this is the Pre UUT Loop callback in TestStand.
The Exit group is only executed once at the end of the day when the application is terminated. It is used to free all the used hardware and cleanup all the resources. This probably is the Post UUT Loop Callback in TS.
When a product needs to be tested, the operator presses the "start" button which triggers our own Test Sequencer and the run and abort group are being executed (first the run group, afterwards the abort group).
When the product is being tested the "running led" of the little box lights up to indicate to the operator that the application is running. (only when the run and abort group are running)
The Run group has all the functional tests in it. (MainSequence)
The abort group is used to put everything back in it's original state after the test on this single product is done. (Post UUT)
When executing the tests and something goes wrong (operator gets stuck in a clamper, ...) the operator can still press the abort button and then the execution immediately jumps from the currently executing step in the run group to the first step of the abort group. So, when something goes wrong, immediately the abort group is called.
At the end of the run and abort group, if no errors occured, the "pass led" lights up. If one or more steps went wrong the "fail" led lights up.
This setup can also be used to test multiple product in parallel. At that time all the different parallel testers have such a small box which contains a "start" and "abort" button and a pass, fail and running led. (it is possible that they are all connected to the same PCI-DIO-96 board. )
My question:
Is it possible to do something similar like this in Teststand? If yes, is there an example available that shows me how to do this in TestStand? (externally trigger the execution of TestStand)
Typically, in the Init group (Pre UUT Loop) the digital interface box gets initialised.
In the Close group (Post UUT Loop) the digital interface box is taken out of scope.
Note: The PCI-DIO-96 board to which the digital interface box is connected will also be used in the rest of the developed application (MainSequence, ...)
What's really important for me is that I can create a process model that all the application developers in our organisation can use. I really don't want any of the application developers (limited software experience) to mess around in all the features of TestStand.
For them it's important that they just add the function DigitalInterfaceBoxInit () in the Pre UUT Loop Callback and the DigitalInterfaceBoxClose () in the Post UUT Loop Callback, and then everything works!
It is important that the appliation developers do not have to create any global variables, other functions, synchronisations, parallel sequences, ... in TestStand. All this needs to be done with a simple call to the DigitalInterfaceBoxInit function.
Thanks in advance for all the help!
Best Regards,

Dennis-
Your application sounds very well suited to TestStand's abilities. I am also quite impressed with your knowledge of how TestStand's architecture is arranged when you are still just considering whether or not to use it.
I think that TestStand would work really well for you in this application. Like you mentioned it will provide you with a form of standardization for your application developers to work from. It also provides the flexibility for you to add your custom routines in many different places. TestStand also makes parallel and batch testing much easier in TS 2.0 so that you could develop one test for your product and execute different instances of it in parallel to test multiple products at once.
As for your specific question about how to c
ontrol TestStand using a DIO board. I think this is very feasible and should not be too difficult. Since TestStand provides you the ability to create a custom operator interface your operator interface could monitor the status of your DIO board and launch/abort executions based on the read values. Usually the executions are launched/aborted when a button on the GUI is pressed however, I do not see any thing different about basing the action on a DI signal vs a mouse click. I am sure your application is more involved than this high level description but from the sounds of it I think it is very possible to do with TestStand.
Based on my experience of building test systems with TestStand and your description of the application, I would feel very confident in using TestStand to achieve all the goals you mentioned. If you have further detailed questions on how one of your features might be implemented, feel free to contact one of our Application Engineers or email us at www.ni.com/ask
and we would be glad to help you.

RT Code aborts

Hi
We have been facing a strange problem for over 2 weeks.
We have developed an application that works on client-server communication.
PXI-RT acts as the server and the RT application is delpoyed to run on startup.
Host PC receives data continuously from the RT for analysis, processing and display.
the RT acquries data from a max of 63 channels (PXI and SCXI), decimates the data by a factor defined by the user and transmits it to the host.
for over few days, the RT code was observed to abort execution after nearly 20 min of execution. Data was acquried from a max of 63 channels at 5KS/sec.The RT aborted irrespective of the number of channels being configured for acquisiton.
The duration after which the code aborts varies between 10 min and 20 min.
We were not able to trace the reason for this behaviour. We tried increasing the delays and timeouts in the communication vis.
If anyone out there can suggest the possible fixes to this issue, it would be grateful.
Any more information regardign the system, if needed, will be given.
Thank you

Memory does not change rapidly. It increases slowly to around 60% before the code aborts. The CPU usage jumps between a higher and a lower value, till it actually ends up either at 0% or at 100%
Message Edited by MScap on 11-10-2008 08:53 PM
If memory is growing even slowly to 60%, I would strongly suspect a memory leak. Does anything about what you are doing in the code make sense that the memory is growing?
I would suspect that you have arrays that are growing with time. If the array grows to be larger than the space it currently occupies, then the memory manager will shuffle it in memory until if finds a contiguous space in memory to hold it. If the array grows so large that there isn't a large enough block of memory to hold it, then I believe the system would crash. Even though you are only using 60%, that means only 40% is free, thus less than half the memory. If the array has grown over time, the array may now be larger than 40% of your memory space.
Take a close look at what operations you are doing to your arrays and make sure you are not growing them unnecessarily. Preallocate space for arrays by using initialize array functions. Use replace array subset in code rather than build array or insert into array, maintaining the array between loop iterations using shift registers along with any other data you need to hold such as how much of the array contains valid data.

How do you force DAQmx output to 0 at the end of program execution?

I am using a 6713 to generate an arbitrary analog waveform on its output. However, once the labview vi has finished execution, the output voltage from the 6713 does not go back to 0 V. I have tried to force it back to 0 V by appending a 0 V amplitude waveform to the end of the analog waveform to mixed results (if I give it thousands of points, it goes to 0, but if I make it a more reasonable 100 points, it doesn't). How can I force the output back to 0 V. I tried stopping the task, clearing it, and stopping it and then clearing it. None of those worked.
Any help would be greatly appreciated.

6713 Interface.vi ‏144 KB

First, I have to ask, did you write this VI?
It is very hard to follow and has a lot of confusing structures in it. IN the middle area where a lot of the DAQmx functions are, the error wire loops around so much it is hard to tell what is happening in what order. To the lower left, an array is converted to a cluster, the cluster is unbundled, the individual elements are fed to a compound addition to get a single value. Why not just use a sum array function on the original array?
The stop button is fed to the Stop Sign function. This is Abort execution which is the same as hitting the red stop button at the top of the VI. It ends the execution of the VI right then and there and doesn't allow anything else to happen. Read the context help for that function. As someone else has said on the forum, "Using the Abort button is like using a tree to stop your car. It will stop it, but there might be consequences."
How is this VI being run? Is the Run Continuous button being used? My guess is yes because I don't see any While loops and the only thing the stop button does is end the program abruptly.
You will need to rethink your whole architecture. Stuff that needs to happen once should be set up before a while loop that has wires leading to the while loop or uses a flat sequence to make sure that it happens first. This is you program initialization.
Everything that happens repeatedly would be in the while loop. The front panel Stop button is what ends this loop.
Anything that has to happen before the program ends like closing out tasks happens after the while loop (either by wires for dataflow or in 3rd frame of a flat sequence structure. With this, you should be able to reset your tasks so they output a zero voltage from the analog outputs before the tasks are closed and the program ends naturally.
Appending a zero to the end of the waveform won't help because if the waveforms run continuously, it will restart back at the beginning.
I would highly recommend looking at the example VI's for DAQmx functions and taking the tutorials for Labview that are available on the NI website.

The camera code is an ActiveX/COM DLL that you are calling out to. Unfortunately, when a thread leaves LabVIEW and calls external code, we have no control over it anymore. When you abort the VI, we'll stop the code execution, but we have to wait for the COM DLL to release the thread.
Being able to do this is outside our control, unfortunately. You should look at the camera API, or talk to the vendor, about a method that either has a timeout or is asynchronous in nature.

Get individual test socket execution reference

Hi All,
Versions used: LV 2014, TS 2014, Parallel model with each DUT independently tested, Custom OI built as per need
I have an application where at most 8 test sockets can run at a time, independent of each other. Each DUT must be independently started, paused or aborted from LabVIEW custom OI. How do I get the individual test socket execution reference so that I can send the pause/abort command from LabVIEW Operator Interface? I tried using the FileGlobals.TestSocketExecutions array from the Parallel model (by setting "Shared at Run-time" flag), but these references seems to be changing constantly.
What I want to do is have a unique execution reference for each testsocket that can be obtained when the DUT is started/ even when the testsocket is spawned, store that reference in my LabVIEW code and use this execution reference when I want to pause/abort the testing in that particular socket from LabVIEW OI.
Thanks in advance,
Saranya

Saranya,
I assume (hope) that you are using the "Test UUTs" execution entry point in the parallel model. So it seems to me that you already disabled the "UUT Info Dialog", otherwise you would have blocking functionality which requires user interaction on the UI dialog.
Please look into the Parallel Model as well as the modelsupport2.dll sources (available as CVI project in TS model folder) how the synchronization is done there.
Hint: There is a queue....
Also, i hope that you mixed abort with termination. I highly recommend you to never abort executions.
