• global variable functional to read and write data from and to the parallel loops

  Hello!

  Here is the following situation: I have 3 parallel while loops. I have the fire at the same time. The first loop reads the data from GPIB instruments. Second readers PID powered analog output card (software waveform static timed, cc. Update 3 seconds interval) with DAQmx features. The third argument stores the data in the case of certain conditions to the PDM file.

  I create a functional global variable (FGV) with write and read options containing the measured data (30 double CC in cluster). So when I get a new reading of the GPIB loop, I put the new values in the FGV.

  In parallel loops, I read the FGV when necessary. I know that, I just create a race condition, because when one of the loops reads or writes data in the FGV, no other loops can access, while they hold their race until the loop of winner completed his reading or writing on it.

  In my case, it is not a problem of losing data measured, and also a few short drapes in some loops are okey. (data measured, including the temperature values, used in the loop of PID and the loop to save file, the system also has constants for a significant period, is not a problem if the PID loop reads sometimes on values previous to the FGV in case if he won the race)

  What is a "barbarian way" to make such a code? (later, I want to give a good GUI to my code, so probably I would have to use some sort of event management,...)

  If you recommend something more elegant, please give me some links where I can learn more.

  I started to read and learn to try to expand my little knowledge in LabView, but to me, it seems I can find examples really pro and documents (http://expressionflow.com/2007/10/01/labview-queued-state-machine-architecture/ , http://forums.ni.com/t5/LabVIEW/Community-Nugget-2009-03-13-An-Event-based-messageing-framework/m-p/... ) and really simple, but not in the "middle range". This forum and other sources of NEITHER are really good, but I want to swim in a huge "info-ocean", without guidance...

  I'm after course 1 Core and Core 2, do you know that some free educational material that is based on these? (to say something 'intermediary'...)

  Thank you very much!

  I would use queues instead of a FGV in this particular case.

  A driving force that would provide a signal saying that the data is ready, you can change your FGV readme...  And maybe have an array of clusters to hold values more waiting to be read, etc...  Things get complicated...

  A queue however will do nicely.  You may have an understanding of producer/consumer.  You will need to do maybe not this 3rd loop.  If install you a state machine, which has (among other States): wait for the data (that is where the queue is read), writing to a file, disk PID.

  Your state of inactivity would be the "waiting for data".

  The PID is dependent on the data?  Otherwise it must operate its own, and Yes, you may have a loop for it.  Should run at a different rate from the loop reading data, you may have a different queue or other means for transmitting data to this loop.

  Another tip would be to define the State of PID as the default state and check for new data at regular intervals, thus reducing to 2 loops (producer / consumer).  The new data would be shared on the wires using a shift register.

  There are many tricks.  However, I would not recommend using a basic FGV as your solution.  An Action Engine, would be okay if it includes a mechanism to flag what data has been read (ie index, etc) or once the data has been read, it is deleted from the AE. 
  
  
  There are many ways to implement a solution, you just have to pick the right one that will avoid loosing data.
  

• CD rom only reads or writes data

  After several days to burn backup discs, my computer cd rom drive to read data from the drive.

  Hello

  You have disk problems as the CD/DVD is actually 4 discs in 1 case (CD & DVD burning and)
  Playback of CD and DVD). So it is not unusual for parts from 1 or 2 to not work so that others do
  correctly.

  Burning at low speed, or by using the master could help. A CD/DVD cleaner might help.

  Brand of the CD or DVD drive can also be the problem. Low quality (cheap brands) are always problematic.

  CD/DVDs have a tolerance + - and your can read/write on the edge outside these discs
  tolerances. They may be delivered, but it is generally more economical to replace the disk.

  Try this - Panel - Device Manager - CD/DVD - double click on the device - driver tab.
  Click on update drivers (this will probably do nothing) - RIGHT click ON the drive - uninstall.
  RESTART this will refresh the default driver stack. Even if the reader does not appear to continue

• Read and write data to the content repository.

  Hi all
  We use the content repository to store a document and images on the web server in the Center.
  So we have created/setup a repository of content on the web center.
  Please proivde me some might document page to get an idea of how I can read and write the date
  content repository.
  You are most welocme to provide some idea /suggestion.
  Thank you
  Arun.

  You are using webcenter spaces or you create a custom application webcenter?

  When you create a custom application webcenter, you can make use of the workflow Documents. Jdeveloper resources catalog, you will find a few flows of Documents job that will allow you to add some components to manage documents in a folder structure.
  You must first create a connection to your content from your application server. This can be done in the Application resources, right-click on the connection and in the context menu, select "content repository". Them you must filll in connection to your content server details. Make sure you have selected "Set as primary connection for document service" because otherwise the document taskflows you deposit on your page will not find a connection.

  Once you have added the connection, you will also find a datacontrol to the content repository. In this way, you can use the datacontrol place the taskflow and you can create several custom tables.
  I'm not sure but I think the datacontrol also include surgery to create the document but I'm not sure...

  And if not enough, you can always do use the webservices provided by content server. In Jdeveloper you can easily create a datacontrol from Web services by providing the wsdl file. UCM provides for services so that you can import the wsdl into your application and you can easily create your own forms checkin, tables...

  Here is some information on how to integrate services document:

  Any ideas?

  Hello

  Have you tried different burning software?
  I m using Nero and in my opinion one of the apps better combustion.
  Here, I can choose between CD, DVD, DL or Blueray (only possible if the CD/DVD drive also supports this).

  Have you also checked diffΘrents CDs from different manufacturers?
  You should do this since not all disks are 100% compatible.
  I had several problems with different CD or DVD in most of the cases it was a compatibility issue, I tried TDK and this kind of drive is compatible with my CD/DVD drive

• How to write data in an Excel spreadsheet protected (with unlocked cells)?

  Hello!

  I have LabVIEW 8.2 and I often use the report Generation Toolkit for Microsoft Office' to save data in Excel spreadsheets. So far, I only used the leaves unprotected.

  But right now, I have an Excel worksheet protected by some cells unlocked. If I open the file using Excel I can fill these unlocked cells without any problem. However, I am not being able to fill these cells unlocked using LabVIEW and the Toolbox. I have a few questions:

  (1) is it possible to use LabVIEW to write data in a protected Excel worksheet, even though she has unlocked the cells?

  (2) if it is possible, how can I do that?

  OBS: I noticed that if I unprotect the sheet, I can write data to the file. But I don't want to be protected and the protection of the sheet, since users will not have the password.

  I hope that I was clear. I really appreciate any help you can provide.

  Thanks for the replies.

  Use ActiveX I could write the cells individually. By doing this, I could write in the unprotected cells without any problem. hour

  Probably, the Toolbox has been activated somehow the overall protection of the spreadsheet and Excel was not allowing writing.

  I had never used before ActiveX, so I had to learn it from scratch. I was looking for some tutorials on the internet but I have not found much information easy. What struck me the most help is an example that comes with LabVIEW named "Excel - write Table.vi. After some tests, I was able to open my data protected from the worksheet and fill in the unlocked cells.

  Thank you guys!

• DVD/CD RW do not read audio CDs or data or save a blank CD, but that it's ok to read and write DVDs

• Speed up the transfer of data from Excel

  Hey!

  In my VI, I need the contents of 3 Excel files. The VI then takes in the filter criteria and uses them to filter all the data and produce graphs. Problem is that all 3 Excel files are more than 8000 lines deep and wide of 40 columns. She takes super long to get the data from one of these worksheets, nevermind 3.

  IM only starting this project, so I wanted to find the best way to address the issue.

  Is it possible to quickly transfer all the data from Excel to LabVIEW?

  If I read once and then writes it to a binary file for quick access, which would be better?

  I'm under that LabVIEW 2009 on Windows XP with report generation tool installed too.

• Qosmio X 500 does not write data to any CD

  I have a Qosmio X 500 with windows 7 (64-bit) home about this, my CD-Rom used to work fine, now it reads and serious DVD and blue-ray, but it will not read or burn CDs.

  I have no more or less than the registry filter.
  How can I solve this problem?

  Hello

  Have you tried different CDs from different manufacturers?
  Try the CD R TDK.
  I use this kind of CD and never had any problems, but had problems to write data to the other CD.

  In addition, you can try to clean the laser lens you can use a piece of hydrophilic cotton and a very small little alcohol which should be good enough.

  By the way: fire what app do you use? In my opinion Nero is great software, one of the best software in this segment.

• Write data to text file generates the error

  Hi all

  I need to write data to a file using TestStand and I configired the entrance and outside like below, but I get the error message like ' an error occurred 'Write' calling in 'ITextStream' of 'Microsoft Scripting Runtime' [error Code:-2146828234].

  I followed the same procedure for reading text that works very well for me.

  Hope others might have faced the problem / or I do something wrong.

  Do what is necessary.

  

  Found problem while opening a file I used IO Mode ForReading instead of ForWriting.

  Unnecessarily the thread created, but then hope this can help someone later when they deal with a particular issue.

• DAQ read and write synchronization

  I would like to acquire the data permanently (I) and sometimes write data (AO).

  Currently I have a Subvi permanently this bed to 125kHz. The data is passed to a queue. Another Subvi accepts a user input and provides output tension affecting playback. I traced reading and voltage on a chart. I noticed that over time, the input and output lose alignment. Initially, it is +/-10 ms and then past at 100 + ms - as the control voltage above reading expected by 100 m I switch the control voltage to the Subvi acquisition via a global variable and insert it into a table with playback.

  I am sure that is not the way to do it, but I can't see how trigger can help me here, given that the reading should be continuous. I just need to align the output to the input of my land.

  I solved the task:

  I put a VI "get the date and time" in a structure to deal with the writing of data acquisition. Then, I used the wave function of build and wired an array of unique value (the value of the AO) with the time stamp (to). So instead of using a waveform graph, I used a XY Chart and traced this waveform, but also the waveform of analog input (combined in a table). So if I send a voltage pulse at time t = 100 ms, I see an increase at t = 100 +/-1 m higher, I see the rise at t = 100 + dt ms (dt ~ 10 to 100), because the data was drawn from the buffer too slowly.

  Since I am acquiring data at all times, regardless of the result, triggering is not really useful here.

• How to read and write attributes using the API?

  I'm trying attributes of access (read and write) of the following:

  SequenceFile

  Sequence

  The sequence steps

  When you look at the documentation of the API, TestStand, the following functions are available:

  PropertyObject

  Properties

  Attributes (read-only)

  HasAttributes (read-only)

  Methods

  DisplayAttributesDialog

  I tried to use the SetValString and GetValString commands using the reference of the attributes, but it does not seem that the data is stored in the file.

  I can't find the following information in the TestStand API:

  1. Where the attributes are stored in a property object?
  
  
  2. How can we access through the API?

  No advice and no information is appreciated!

  You must increment the number of changes to the file after that editing the sequence editor (or UI) won't refresh or mark the file, as amended. Use sequenceFile.AsPropertyObjectFile (). IncChangeCount().

  SequenceFile attributes are stored in the SequenceFile.Data, not the object of SequenceFile object. You can change them in the Advanced tab of the properties of the file sequence dialog box.

  Hope this helps,

• DAQmx reads (or writes) in parallel and series

  Is there a performance difference between putting DAQmx reads (or writes) in parallel or series?

  Well said.  In addition, using series would create dependencies of data flow, so the readings could not happen at the time of the soul, where parallel would remove the dependencies.
