• Structure of the event: problem with data transfer

  Hello everyone,

  for three days I'm troubleshooting an issue in LabView with the event structures. I really hope someone can help here, because I can't find anything on the entire WEB.

  I had six groups of equal to a VI entry, each containing five checks enum (among others) where the user can specify some configuration of measurement data. I want the program to do is: to recognize if a any of these enum values has been changed and if yes, then submit the values containing the cluster in a subvi then calculates the wiring and affect the material of the ports. In addition, i need to submit the number of the enum element that was changed, so the program is able to clear the user input in the case of a breach (e.g. If the user sets two entries of enum control 1 meter and 2 Group 1 and then tries to set a third counter of entry to port 3, the program displays a message and deletes third entry as the number of entries of counter is limited to 2 per cluster).

  To resolve this problem, I used a structure of the event with 6 x 5 cases (change of enum value 1 Group 1 Group 1 enum value 2 change... and so on until the change in the value enum 5 Group 6).

  

  The problem is that if the user changes a value, the event structure reacts and performs the proper case; However VALUES of the cluster, the user changed are not subject to the SECOND time that an event occurs. It is a kind of a situation, "n-1". For example, if all five controls Enum of Group 1 are 'disabled' first and the user sets enum 3 of 'Meter entry', the structure of the event runs but submits the values previous to the Subvi (all enums 'Disabled'). When the user makes the second change, say that enum SWITCH1 to "Analog Input", the structure of the event is running again and passes the values of the FIRST user to the Subvi editing, then the Subvi gets data "enum 3 meter inlet and all other disabled enumerations.

  In easier words: if I have new values on my cluster "Kanal 1" (left side of the screenshot) and run the structure of the event, on the right side to "Kanal 1" indicator, I get the previous values (n-1).

  The structure of my event is in a while loop. If I create a timeout every 10 ms, and a loop of 250 ms the waiting time, I got the 80% chance that the recent changes are transferred to the Subvi correctly, in other cases I have a delay of the 1 step as described above. It seems to be directly based on the time that I specify the while to wait - but I can't explain it and I cannot accept a less than 100% chance to transfer the correct data, nor can I accept delays of a few seconds for each loop run. If I indicate timeout (infinite) get delayed 1-1 step values in all cases.

  When I specify cases of event to react on "all items value change" of the structure of the event behaves properly - but then I can't handle indicate which element has changed, as the CtlRef of output in case of a structure does not specify "enum 1, enum 2..." but only "Group 1".

  Does anyone have a solution to this? It is certainly a problem with the structure of the event, but I can't understand what to change.

  Thank you much in advance,

  Mr. Boiger

  This is because the terminal is read until the structure of the event runs.   Terminal is read, the event structure is waiting for an event.  The change in value.  Business events are running, but the value is the old value.

  Put the terminal inside the event.

  Or, you can display the connector called "New value" on the side left (stretching down from the border of the node 'CtrRef').  Use a wire one to come.

• LabVIEW arduino uno bad data transfer

  Hello

  I have some problems with the transfer of data from the arduino uno to labview.

  I did a VI where I can control the power of a heater with measurements of temperature with arduino uno.

  The problem is that from time to time the incorrect temperature is captured in labview by missing the number or a number, for example. LabVIEW gets 1.25 ° C instead of 15.25 ° C or 2000 ° C instead of 20.00.

  When I look at the program arduino tracer series these errors do not occur. So I guess it will be a problem with the settings of labview or my VI.

  Parts joined a set of data extracted from the VI and VI himself and the arduino script

  Yes.  The Subvi has 2 major problems.

  The first is as I said.  You set up and close the serial port each iteration.  There is a risk that the device could be send data that you won't miss the moment, that the port is closed.  (Even if she doesn't really explain why you miss the decimal point in the middle of the data bytes.  Serial ports must be configured and opened when the program starts.  Writing and reading within the loop.  And not closed when the program ends.

  The second major problem.  Why you have the property Bits of data cable up to the number of bytes to read.  Bytes and pieces is two different entities.  And in this case, the data bits is the number of bits of data defined by the configuration of the serial port.  Probably 8 and would still be 8 and has nothing to do with the number of bytes actually in the serial port.  Number of bytes to read is how many bytes you want to actually read the serial port, could be 1, 50, 1000,...

  Is your device send data continuously without asking?  Should I use a stop character?  If this isn't, by using a stop as a return character, carriage or line break, then it should.  It will help you to break the ASCII data that crosses into packets.  Configure your serial port is set up to search for characters of endpoint and it would be a line break character. Use the termination character, and tells your VISA read an arbitrarily large number.  A number that is larger than the longest message that you expect to receive.  The VISA read will return as soon as she sees the character of judgment and you give a full data package.

  It is often a good idea to have a communication protocol of request/response with your device.  You write a command that says 'give me the value.  It reads and responds to the back and gives value.  Otherwise if he sends just data continuously without asking confirmation and that you do not read fast enough, you could extend your serial port (which would give an error and you could lose data), and even before that, you could read old data which is at the front of your stamp series while your device has already sent hundreds of data points more after that.

• Data transfer Assistant - doesn't recognize palm desktop

  I have a Palm Tungsten e I installed Palm Desktop v6.2 so I could transfer my data on my new Pre phone.  My Pre phone is plugged into the USB port on my computer and I selected the USB key on the phone. I then started the data transfer Assistant, has chosen to run, chose following the Welcome screen, chose following to the login window since I already have my phone connected pre, says next message window ' although Palm Desktop is installed, there is no data to transfer.

  This is incorrect. my Palm Desktop contains data.  Why the data transfer Assistant say that?  The only option is left.  How do I get past this so I can transfer my data?

  I did setup a Google mail account and put that on my phone but it seems not to matter.

  Any help would be appreciated.

  I found the solution to my problem with the DTA does not transfer my data from Palm to my Pre phone.  Here are the steps I took:

  (1) backed up the data of palm on my external hard drive

  (2) uninstalling palm desktop and palm versalmail by using Add/Remove programs

  (3) record deleted program files/palm

  (4) pc reloaded

  (5) installed Palm Desktop V6.2

  (6) synchronize Tungsten E PDA to pc

  (7) made 3 new Palm Desktop: 1 user profiles for the calendar, 1 book, 1 for memos address (got this tip from another validation)

  (8) exported calendar data in the profile calendar, address to the address profile data and data Memo memo profile

  (8) DTA started

  (9) selected a profile suitable to transfer to pre - done 3 times.  Wanted to make sure that each type of data transferred correctly and it also gave me the opportunity to choose where I wanted to save the data

  (10) SUCCESS!

  Hope this helps someone else out there.

• Data transfer USB Time Out with large or multiple files at once

  I have a ton of problems with the USB data transfer.  I'm unable to transfer large files or many files at a time.  The external hard drive or flash drive will expire and eventually the pc will 'lose' and will not be able to locate the files I'm trying to transfer.  In addition, I'm not able to sync my new iPad, and I guess that it is caused by the same problem.  The strange thing is, I'm able to use my printer via USB with no problems.

  be a problem?

  Try disabling the USB in the BIOS and use a USB card that is not expensive.

• Complete data store during data transfer

  Hi all

  I'm having a serious problem with the ability to store data, if I transferred a huge amount of data to a virtual machine through SSH. The data store has a total capacity of 511 GB. During the process of transfer of the virtual machine stops, just when the data store is full. So the only solution is to detach other virtual machines from the data store, but it is not enough.

  We are using VMware ESX 3.5 and virtual machine is Ubuntu Server. Here is the configuration of the virtual machine:

  Memory: 1024 MB

  Processors: 1

  HardDisk1: 6 GB

  HardDisk2: 52GB

  HardDisk3: 230GB

  HardDisk4: 256 GB

  Storage distribution and capacity for the VM:

  # df h
  Size of filesystem used Avail use % mounted on
  / dev/map/vg00-VG00_ROOT
  3.4 G 2.6 G 621M 81%.
  No 495M 220K 495M 1% / dev

  / dev/map/VG02-VG02_home_dpto
  479G 219 G 236 G 49% / home-Dept.

  HardDisk3 and HardDisk4 are mapped in a (VG02-VG02_home_dpto) LVM volume and its free space is 236 GB. Space free Dtx200: 4, 56 GB. I don't understand why. The problem may be caused by automatic generation VMDK:

  * ficheros00.platform.core.vmdk-> 6 GB

  * ficheros00.platform.core_1.vmdk-> 54 GB

  * ficheros00.platform.core_2.vmdk-> 241 GB

  * ficheros00. Platform.Core.-000002.vmdk-> 24 GB

  * ficheros00. Platform.Core_2 - 000001.vmdk-> 166 GB

  The first time, I got 20G of free space of the data store removing some residual VMs. Then I tried to copy a folder of 15 GB through the network by SSH from another server in files. It was the occupation during the first use: (just to compare)

  * ficheros00.platform.core.vmdk-> 6 GB

  * ficheros00.platform.core_1.vmdk-> 54 GB

  * ficheros00.platform.core_2.vmdk-> 241 GB

  * ficheros00. Platform.Core.-000002.vmdk-> 10 GB

  * ficheros00. Platform.Core_2 - 000001.vmdk-> 164 GB

  It seems 000002.vmdk and 00002.vmdk develop during the transfer of files, but they do not consolidate data. I don't know whether this is a normal behavior. I think that space used for ficheros00.platform.core-000002.vmdk-> 24 GB and ficheros00.platform.core_2 - 000001.vmdk-> 166 GB should be included in the ficheros00.platform.core_2.vmdk - > 241 GB and end of data transfer that they should disappear themselves.

  We calculate the initial free space before allocating hard disks of the virtual machine.

  In this data store, we currently have 2 VM:

  [root@hp585-01 eva4400:-02] # du-sh ficheros00.platform.core./
  472G ficheros00.platform.core

  [root@hp585-01 eva4400:-02] # du-sh lucus01.labo.core_1/
  36G lucus01.labo.core_1

  Any help would be appreciated. Thank you very much.

  Best regards

  Harry.

  Log files, I see that capture files two instant belong to basic disks on the two different data stores on this host ESXi 3.5 Update 3. In any case with being thick implemented basic disks, you should be able to delete snapshots in the snapshot with off the virtual machine Manager. If the virtual machine is still on when you delete the snapshots, you need more disk space for another, temporary snapshot (snapshot to help consolidate)

  When you have removed before snapshots, you did this with the virtual machine power on or power off?

  Turn off the virtual machine will be to free up disk space (the .vswp file is deleted) and merge data from snapshot (with only a single snapshot per virtual disk) in basic disks should not require additional disk space.

  Because the Snapshot Manager doesn't show pictures anymore after the failure of the attempt, you will need to create a new snapshot (to activate the button 'Clear all') and hit use 'delete all '. Because of the size of snapshots, it may require some time to merge data in basic disks, so be patient, even if the GUI user expires!

  André

  PS: Please check that the second VM on the data store does not work on snapshots too, who could fill the data store so that you remove snapshots of the virtual machine in question!

• Assistant (DTA) data transfer transferred some of my Contacts, none of my calendar or Memo files

  When I ran the DTA at 5:30 PM PST yesterday, he said he had picked up ~ 4100 chronogram (Palm Desktop 6.2), with the exception of 20 files of calendar, which was very good.
  
  On my old Palm device, he said I had ~ 1300 address book records, ~ 2000 Date record book and ~ 850 record Memo. So when the DTA said he had picked up ~ 4100 records, which seemed all right.
  
  When you are prompted on my pre, I chose to sync my data with Google.
  
  Immediately after this one-time transfer process, I checked my pre, and there is no record of my old Palm Desktop Contacts, calendar, or PRE memos. I thought that I should wait to see what happens.
  
  About 7:30 PM PST yesterday, slightly more than half of my Contacts has appeared in Google Contacts section 'My Contacts' (725 total) and on my pre. The same recordings were in Google Contacts and on my Palm Pre. Furthermore, none of my calendar or Memo files had been transferred more to my pre or Google (for the calendar).
  
  I thought that maybe the data transfer was still running, so I waited all night.
  
  Since this morning 9:45 AM PST, nothing has changed.
  
  My Pre and Google seem to have incomplete data:
  -slightly more than half of records from address book Palm Desktop 6.2 made to my pre / Google
  -any of the records in Palm Desktop 6.2 Agenda made my pre / Google
  -any of the records in Palm Desktop 6.2 memos made my pre / Google
  
  SUMMARY: I'm extremely frustrated. The only thing that I have always enjoyed with Palm devices has been the opportunity to upgrade to the new Palm devices and carry my existing data. The one-time transfer of DTA to pre process is very buggy. Somewhere after the DTA extracts data from my Palm Desktop (~ 4100 records), most of these documents have been lost. It is a horrible customer experience.

  I did some online research, and the author of the following article also fell on a similar problem:

  http://blog.Treonauts.com/2009/06/Palm-pre-sync-solutions.html

  I have tested and verified that when I create a new record on my pre calendar, he gets sync would correctly in Google Calendar and vice versa (new record created in Google Calendar sync does get would be my pre). It is very good for new data. But what of my thousands of existing data records? All these anniversaries, critical telephone numbers, addresses, etc.?

  Before this experience Pre DTA, I've that Palm had their pretty solid synchronization architecture, while the Apple iPhone synchronization architecture (via iTunes) was poor. But at least iPhone na not lose all records along the way.

  So I figured out how to get all my Contacts to load into my pre.

  Initially, I tried to transfer my data using DTA to Google instead of Palm profile. Several times I tried to run the DTA to transfer my contacts from Palm Desktop 6.2 to Google contacts. Whenever I tried to do, at some point, sync Google contacts folders would stop permanently, until all records have been transferred to the course. You can find out how many records have been sync'd to a given pre Contacts by clicking on Preferences & accounts by clicking on the account. You will see the number of contacts.

  So I decided to try to use the Palm profile as the storage for my Contacts and calendar, and all my Contact records (total 1372) was migrated successfully on the Meadow

  The pre now displays contact records in my pre Contacts as I expect: I see the files I transferred over my Palm Desktop. And because I added a Gmail contacts, Gmail addresses friends get "linked" to the corresponding Contacts automatically.

  Summary: my recommendation is that, for the DTA transfer process, you choose to store (backup) your Contacts (and calendar) on the Palm profile. Of course, the downside of this approach is data that has been created on your Pre will not be displayed in Google Contacts and Google Calendar. Of course, you can choose to add your Google accounts on your Pre to your Contacts and calendar, which is what I did. This makes the Chronogram of your Gmail contacts and introduce you to Google Calendar on your Pre. For example, I added the calendar we vacation on Google Calendar. And now these holiday appear on my Pre calendar.

• Slow data transfer between computer and HP Laser Jet 1320n

  I recently bought a laptop with windows 8.1 and successfully connected to 1320n times via LAN and wireless networks.

• Sudden slow data transfer

  Hello

  I am happily using my 3 GB Time Capsule for the last 18 months with no problems. I use it almost exclusively as data storage for my Plex server. I use it wirelessly to my Macbook Pro 2014, in the same room.

  Yesterday, without change to explain it, it has become very slow to transfer files to it.

  

  I am at a loss, as most of the solutions I looked for people who have had problems of speed from the beginning, mine was a sudden appearance.

  Speeds do not seem to affect my streaming quality that I can still watch a 1080 p 5 gb + video file without stuttering or offset. The problem is isolated to the data transfer it seems.

  Any suggestions where to start?

  I use it almost exclusively as data storage for my Plex server. I use it wirelessly to my Macbook Pro 2014, in the same room.

  The plex server is connected by ethernet?

  Speeds do not seem to affect my streaming quality that I can still watch a 1080 p 5 gb + video file without stuttering or offset.

  It would be difficult to know if streaming is more... and more through your Macbook wireless...

  So I just need to know what is connected by ethernet and what is connected by wireless.

  Wireless is seriously affected by a number of things. So I guess that the first test is to connect the laptop to the TC by ethernet and make sure that it works very well. If your ethernet Mac buy a crush on ethernet card... a necessity, in my humble OPINION... as trying to fix wireless more wireless resembles sawing off the branch that which you are sitting.

  If you can determine the network of the question... Then we can do the simple things...

  Run the diagnostics wireless...

  Just restart the entire network, which I am assuming that you tried but did not mention.

  Simultaneous copy of a file on the hard drive while also streaming can also be stressing the TC... If the tests should be carried out without any other use of disk passes.

• making data transfer between two computers

  Hello

  I developed a labview for data acquisition goal program.  I need to run a part of my program in a computer and some said in another separate computer. for data transfer between these two computers, I decided to use the Protocol of data taking. a computer, collect data and send data to the second computer and second computer will control the setting of data acquisition in the first computer. now I have developed the program but it does not work. I wonder if that is enough to link these two PC by a network cable or something needs to be done. of course, I have some problems with the source definition in the Protocol of data taking. need two labview program in two separate computers.

  Best regards.

  the problem is resolved.

  transfer of data from socket, simply connect two computers with a LAN cable, as I did. The problem is the URL parameter. I got the error as follows:

  ==> in main and remote program, the URL must be the same and the computer name that data socket server is running must be incloded in the two URLS. (my mistake was that I had used two different URLS in the main program and remote). either way, I realized that this isn't neceessary to Server execution data socket in the two computer.but that that send data.

• PXI data transfer between OTN and FPGA

  Hello

  I have a DAQ card in my PXI and a FPGA 7813R map.

  The problem is that I send sample waaveforms of the data acquisition card to the FPGA card (which only has digital i/o) to launch my control on the FPGA. When I generate a sine wave of 50 Hz in the OTR to simulate a measured signal and send it to the FPGA through the controls in the Panel before (http://zone.ni.com/reference/en-XX/help/371599G-01/lvfpgaconcepts/pfi_data_transfer/) the signal happens on the fpga is much slower than 50 Hz indicating this folding is (it takes too much time to send the data). I tried to use this method of data transfer because my control requires only the more recent data, but it also has a phase lock loop that requires the data arriving at least resemble the original signal. Another criterion is that the control to data more up-to-date as possible. I know there is another option of the use of DMA FIFO, but I use it because I thought it would take more time to send the data, because each value must be sent.

  My questions are:

  I go about it the correct way? I know that there is the FPGA cards with analog inputs. I buy one it is because I have a large amount of differential analog inputs (20 +)

  Is there a quick way to transfer data to the FPGA. (I have converted all the FXP data before writing to the FPGA)

  Hi Jagwa,

  You should not have to synchronize the RTOS loop that written information and the FPGA VI which is read.  Instead, you can simply use a FIFO.  In RT, you can write all the data points for the FIFO, and then you can extract them one at a time on the FPGA VI and use them as needed to control functions.  In this way, the only time you need to worry about stopwatch the FPGA VI to get out the data to mimic 50 Hz.

  Kind regards
