What is test stand ? Why is it used, how to get going ?

Hello All,
I am LabVIEW user and very new to test stand, have few basic questions,
1. Why teststand was introduced ?
2. In LabVIEW we write VI's and build a project to execute a big task, how is this done in teststand?
3. I did download some of the pdf from NI website, but not able to visualise what needs to be done,
Pls do share if you have more insight to Teststand.
Thanks

Hey systemcrash,
I will try and answer your questions the best I can:
1. http://www.ni.com/teststand/whatis/
TestStand is an automated test executive (ATE). It is an off the shelf solution which makes your life easier. It handles report generation, user management, sequencing (i.e. test flow), result collection, pass/fail analysis, common User Interface, database logging, etc... Basically, all the crap you don't want to develop in LabVIEW. But it gives you consistency and commonality for all your tests. If you look at the layers of the test system TestStand would be at the top like this:
TestStand
LabVIEW (or other software)
Hardware Drivers
Instruments
UUT (unit under test)
2. In TestStand you have the development environment (Sequence Editor) and the User Interface. They can both execute tests. The User Interface is an application written in LabVIEW (or other programming languages, ships with TestStand) which gets deployed to a test station so that testers can execute your test. It does not have the ability to edit the test (in TestStand tests are called Sequence Files). However, the Sequence Editor can edit the tests and would be used on the development machine. There is a deployment utility in TestStand which allows you to create an installer. In that installer you would include the TestStand Engine, the User Interface and all the dependencies for your test (Sequence File). Then the user just opens the User Interface and runs it.
3. NI does offer TestStand courses which can be helpful. I recommend going through these PDFs though first:
http://www.ni.com/pdf/manuals/373200c.pdf
http://www.ni.com/pdf/manuals/323436a.pdf
You will get more out of the classes if you have starting playing around with it first.
Hope this helps.

What is MRP and why it is used?

hi
this question was asked in an interview can some one explain in detail for me
What is MRP and why it is used? If there are 2 Lakhs of items is it feasiable to run MRP since running of MRP for 2 lakhs of item is time consuming, if yes then how it is been done?
thanx

Dear Bashir,
1.MRP is material requirements planning which plans the required quantity of depedent material's along with the required date.
2.MRP procedure is sub divided into a normal MRP,Master Production Scheduling and Consumption Based Planning.
3.Cosnumtion BAsed planning is further sub-divided into Time Phased Planning,Reorder Point Planning and Forecast based
Planning.Reorder point planning can be automatic or Manual.
4.MRP type is differentiated using the MRP type value assigned in the MRP1 view of the material master.
5.Some of the MRP types are PD - MRP,M0,M1,M2,M3 - MAster Production Scheduling related,VB - Manual reorder point
planning,VM-Automatic reorder point planning.
6.It is possible to take the MRP for the whole plant/for a specific MRP area using the batch MRP job.
7.MDBT is the T Code for scheduling the MRP job or it can be scheduled for the program RMMRP000 using the T Code SM36
and the results can be checked using SM37.

What is powerd and why is it using so much cpu

When I check the activity monitor, it is almost pegged out. Because of this other things run slowly. So, what is "powerd" and why is it all of a sudden using so CPU?

It is something related to power management, but it shouldn't be running away like that.
Select it in Activity Monitor and then Quit it using the "X in octagon" button. You should only need Quit, but try force quit if needed.
It will restart, but hopefully it won't start running away. If it does, there is likely something else causing it to do that.

What is bogon doing in my sidebar and how to get rid of it?

Out of the blue today in Finder's sidebar, in SHARED, just under the Time Capsule a new item popped up:
"All..."
Selecting "All..." in sidebar shows in Finder's right panel as follows:
under Name - bogon
under Kind - Neighborhood
Restarting Mac, restarting Time Capsule, disconnecting and reconnecting cable modem - nothing helps, I can't get rid of it and I have no idea what it is...
Just booted my MBP and wife's MB - same thing in both...
It indicates that it is Time Capsule showing the "All..." bogon Neighborhood, not an individual Mac.
Have I been hacked? How to get rid of it, there is no eject next to it?

bogon just disappeared from SHARED on my iMac ... - although mystery remains as it still shows up in MBP ...

What is BitLocker and Why Should We Use It in Windows 7 Ultimate & Windows 8 ?

Hello ppl. Today, I'll try to tell you about BitLocker function in Windows 7 Ultimate & Windows 8 in clear words. When we save a document in our harddisk folders these info are easily can be acquired by a hackers if your system is insecure though a good hacker can beat all kinds of antivirus and firewall software. But !!!
If your data are saved encrypted on your harddisk, it is impossible to see that data though these clever guys stole your sensitive info. Because the data can not be seen without a log in password if they have been saved with encryption!!! So here is what BitLocker does!!!
BitLocker saves all your information by encrypting them so you dont have to worry about your sensitive data anymore! Even if they are stolen by other ppl, it's impossible to see your valued work sheets or other personal data such as pics and bank account information as long as you have a good BitLocker password like A3#Be$%Er or whatever.
BitLocker is a standart feature added to Windows 8 but you should upgrade to Windows 7 Ultimate to use it in Windows 7.
I'll also start a topic about how to activate BitLocker in Windows 8 shortly.
I try to tell in clean words when I create a topic to help those who have basic knowledge about IT. I hope this helped. If you still have questions about BitLocker please dont hesitate to ask me about them.

Hi
Thank you for your post . This is a good information which can help users to be protected from hackers
Cheers!!!

Nsurlsessiond - what is this and why does it use alot of data?

Hello
Firstly
I was in a public library, uploading to my dropbox account, and all of sudden my network speed indicator/ montior showed heaps of download and fast too.
but i was not downloading anything.
I was upping to my dropbox account.
In activity monitor i noticed this service was operating "nsurlsessiond"
What is this service?
In my connection alert it tells me nsurlsessiond tried to establish a connection to apple-dnld.vo.llnwd.net on TCP port 80 (http)
Secondly, i was using my own wifi, and saw this nsurlsessiond service consuming heaps of data. Again I was upping to my dropbox account. About 1gb this time.
Now I have blocked communciation to "nsurlsessiond"
What is the impact of blocking such communication?
please see details of service in screenshot
Now after this experience, I am wondering is it apple policy to have communication from our macbook's to somwhere without us knowingly allowing it? I thought apple was respective of our privacy, or has this changed?
thankyou for your help and time.
regards

i couldnt say. it was just that i happen to be only upping, to dropbox, and then saw downloading on the monitor.
that was triggered as odd.
i rarely look at what services are going on... only if my macbook slows down or something else odd.
in both cases i was only upping to dropbox.
i dont do alot with my macbook, other than upping to dropbox laterly.
thankyou for your thinking and help.

Hello, is there a way that the Test Stand APIs can be used for ASP / Web?

Hello,
I do hope someone can be an idea.
Is it possible that the TestStand API's can be used for ASP/Web?
Currently, we are using Teststand running on exectuble application, but if the TestStand API's can be used on web (Just the operator interface), then it will be easier for engineers/operators to see the results locally and remotely by a web browser.
Any ideas?
Thanks for the help.
Mhelinx

Mhelinx,
i don't think that the TestStand API can be used in ASP very nicely.
TestStand is an ActiveX Server and it seems to be possible to use ActiveX in ASP, but i have read that doing will require reboots of the server from time to time (never done that myself, so relying on 3rd party information).
But there is another, maybe better approach:
Using LabVIEW as your user interface, you can use the Webserver capability of LabVIEW to include the functionality of your UI into your ASP webpages. You can create different "looks" for your application in the webpage while the LV UI stays always the same......
I have never done this as well, and it might be a bit tricky to access data from the visible controls though.
hope this helps,
Norbert
PS: If you are using C# for the UI, i think that this is possible as well....
CEO: What exactly is stopping us from doing this?

Ubd activity - what is it, and why is it using 87% of my processors, and killing my battery?

I have only seen two threads that have the term ubd and battery. I've shut off my bluetooth, my wifi, and all of my apps, and ubd still fluctuates between 7% and 87% with no explanation. I have a new MPB (non-retina), and my battery lasts perhaps 1 hour doing emails and internet. I can't go unplugged at all and expect to do photoshop or any other processor-intensive app. I'm on 10.8.3, and I've got 16GB of RAM, and a 1TB 7200RPM internal hard drive. My wife's 13" mbp is 3 years old, and she is on 10.7, and she gets 4 hours of usage in lightroom and photoshop, so what the heck is going on?
Also, I don't use antivirus or other firewall apps, in case you're wondering. I like to keep background stuff to a minimum.
It would be great if the mac support folks could chime in, and thanks in advance for anyone who might be able to help.
Thanks!

Real Player plugin in use - how to get rid of it?

I tried to play something someone sent me, it required realaudio, I downloaded for free Real player for mac, it didn't do the job, so I tried to trash it, but I keep getting the message above. Anyone knows what to do?
Max

Hey there,
Try logging out and in and then re-attempt to trash it or simply restart your Mac to kill any processes that are still using it. And again, re-attempt to trash the application. See if that helps.
You may want to find a third party utility to "uninstall" the application and trash any files on your Mac that are associated with it. I would recommend [AppTrap|http://konstochvanligasaker.se/apptrap> or [AppZapper|http://www.appzapper.com> to help you accomplish this task.
