Difficulty to read the instrument of series and acquisition of data simultaneously.
Greetings,
I have some trouble getting my VI read from my data acquisition and instrument of the series at the same time. If I run the Subvi simultaneously (i.e. subANG runs in a window and subVEL is running in a second window) both return the correct values and behave as I expect. However, if I call the Subvi in a society mother VI and try to run them both in the same loop structure subANG gets stuck and won't be reprobed with a signal change.
I also tried to use a stacked sequence or plate to separate the execution of subVEL and subANG, but I still get no response to subANG.
The point is is that, if I run Parent.VI in a single window and then creates a copy of subANG (call it '--copy' or other) and run it in a second window, Parent.VI behaves properly and will update the readings as they appear in '--copy '.
I enclose 3 files.
(1) subANG.VI - this bed an an inclinometer RS232 signal. The signal is refreshed every 10ms or more.
(2) subVEL.VI - this bed raw tension of a channel on the acquisition of data, calculates the average then that converts into a pressure difference and finally a speed based on the pressure and temperature inputs.
(3) ParentVI.VI - they simply call and displays the Subvi
My guess is that it's a buffer problem, but I am confused. Someone out there in Labview Earth knows why this might be happening? Suggestions welcom.
It is not an instrument of series. It is a UEI PowerDAq with their typical A/D and the cable.
I found away to make it work by placing subANG and subVEL in some time different loops side by side in ParentVI.

Need help with TS to read the list of variables and/or LV
Hello
I use Labview adapter in Teststand to open WinIDEA and read the values of the variables. Basically LV lib files are used to read the value of the variable at run time, and returns the value of the variable. Contribution to this labview function i.e. variable name string and output type cluster.
I need to read the list of variables and compare it to the value limits for each variable. I perhaps need to read at least 50 to 60 variables in one step if possible or a variable at a time in a loop. I want to add these variables in a txt file with the limits and read of Teststand as a string array and compare the result. In this way is easy to add or remove variables from the list and therefore their expected value. I tried to use the shipper of the property, but there need a stage name or local/global variable.
Another way is to add the code in labview for comparison of variables value read, then I lose teststand power and flexibility.
I am struggling to find the best way to achieve this. Any ideas?
I would like it. Basically, you have a file limit with 2 data tables. A table contains your variables and the other your limits. Then you wrap on a test of a string value.
Let me know if you have any questions.

Hello
Maybe this simple TestStand example will help you.

Remove the Dell recovery partition and create a data partition
Hello world
Two years ago, I bought a Dell Inspiron N5110. In addition to the existing windows partition, I wanted to add a partition Ubuntu as a partition of data (NTFS). Well, I added the Ubuntu partition, but because of the Dell recovery partition (14.65 GB, used 7,69, formatted to NTFS), I had no primary partition left to create a data partition. I did not had the time to solve this problem so far.
Here you can see the different partitions. 4, 66GB there is the linux swap partition and the 18.63 is the linux partition. Of course, they are contained in an extended partition that is created during the installation of linux using GParted.
Basically, what I would do, is to remove the recovery partition. I did not throw a look inside, but I read that as it contains bootstrap information, as well as win7 boot no more if I'm deleting it. The partition is marked as 'active' (in contrast to my main windows partition of C). I guess this is a classic problem, but I couldn't find a tutorial or a satisfactory answer on this forum (I apologize if this is the case). I assume that it is not enough to define steps to activate the recovery partition and assign to the partition c active (i.e. they don't going to critical data recovery to the c partition). Furthermore, I read that repartition your drive could affect the functioning of the emergency recovery partition, is this true?
Thank you very much in advance for your help.
Greetings,
Harald
Yes, sorry, I had a problem and the image has not been correctly incorporated into my message. Here it comes. Sandra means healthy, active, primary partition means that primary partition. However, you will notice that windows see the ubuntu partition is a stretch.

Change the name of files and folders in data warehouses
Is it safe while a virtual machine is running to change the name of the VMDK files and folders in a data store?
I discovered that a VMS VMDK files have a different name for the virtual machine itself, then someone changed the name of the virtual machine after you have created the records
I had to do it a few times, will try to document the process that I follow. If you have many warehouses of data, then make a note of what data store, the machine is in. The next step is to unregister the virtual machine from vCenter / ESXi
Then, you need to enable SSH on your ESXi host
Use Putty or something similar for you connect to the ESXi host
Run the following commands (in italics)
cd vmfs/volumes /
Then run ls to verify that the virtual machine file is here
Rename the folder by using mv
Change to the folder with cd
Rename the nvram, vmsd, vmx and
running again is to say the mv MV oldname.nvram newname.nvram
MV oldname.vmsd newname.vmsd
MV oldname.vmx newname.vmx
MV 1234.hlog - oldname newname - 1234.hlog
Rename the vmdk with vmkfstools EI oldname.vmdk newname.vmdk
Edit the vmx with vi newname.vmx
Replace references to oldname to newname in this file
Register the virtual machine with the ESXi server and it should be OK

Bad drift with USB-6259 devices and acquisition of data PCI-6259
We have both a USB-6259 and PCI-6259 installed on a single computer, linked to a SBC-68, with Matlab and Toolbox of data Acquisiution.
For the purposes of test base, I wrote a script that generates a sinusoidal signal output based MATLAB, for a single DAC output. I wired this single DAC output to two channels of ADC of entry. For each sample output DAC, the script also takes a sample entry of ADC on each channel.
--> Ideally, if everything works correctly, after you run the script, I see two channels of input ADC vector. Tracing of each channel should give me a nice sine wave in Matlab.
--> When I made trace data, here's what I get (see attachment).
-->, I looked at the DAC output with an oscilloscope, and the DC offset is very close to 0 (this indicates to me that the part of output DAC works very well).
Why is there this negative DC drift on two entries?
Forgive my lack of knowledge - I know the difference between the DIFF and CSR connections, but I don't know where is the 'setting' for DIFF/CSR (what is a button/switch on the USB-6259 case? Is it a software control in the code?)

I can't read the FF27 mp3 files and I tried some help I can find.
When I try to play an MP3 in FF27 I get a black screen that says:
"The video cannot be read because the file is corrupted.
The web console shows this:
"Media resources http://tomwhelan.ca/commercial_2014.mp3 can't be decoded."
Any ideas?

From 26 of Firefox, Firefox on Windows XP will attempt to play media encoded MPEG as MP3s natively in the browser. This requires that the necessary components in your system, but they are perhaps not? To turn off the native player and return to the use of a plugin like Windows Media Player or QuickTime for this kind of media, you can make a change to the configuration under the covers. Here's how:
(1) in a new tab, type or paste Subject: config in the address bar and press ENTER. Click on the button promising to be careful.
(2) in the search above the list box, type or paste media and make a pause so that the list is filtered
(3) double-click the preference media.directshow.enabled from true to false.
I don't know if this changes enter into force immediately or after you exit and then restart Firefox.
Note to other readers: Windows XP uses DirectShow (DirectX). Windows Vista, 7, 8 and 8.1 uses Media Foundation to play natively coded MPEG media. It's a different setting.

Hello
Since 2 weeks I have a problem: I always set my settings to restore the previous session with all my tabs and I choose that Firefox asks me where I want to save my downloaded files. Now, every time I close Firefox and I open it again, it is not taken into account and 3 tabs are opened: Firefox, Google, and thanks to install Zotero! I spare it, but every time it opens these tabs and not man. Ditto for saving the files. It goes back automatically to open the start page and save my file in the downloads. Even if I spare, it's the same.
I've desinstalled CCleaner (I thought it might be that), but nothing changes!
Help, please. Thank you very much!
MarthaHere's what I'll try:
- Reset Firefox - that should solve the problem, but it will change the settings like where files are downloaded and what tabs open at startup back to their default values.
- Then change your download and back session restore preferences to how you like them.
Here's how:
- Go to help > troubleshooting information.
- Click on the button 'Reset Firefox'.
- Firefox will close and reset. After Firefox is finished, it will display a window with the imported information. Click Finish.
- Firefox opens with all the default settings applied.
- Open the window of options - tools > Options > general
- In the general Panel set Firefox to open your tabs from last time and set Firefox to ask you where to save downloads.
- Click OK
That should do it. Let me know if it worked.
Thank you
