• problem of data flow in the case structures (using a state machine)

  Good day everyone.

  I'm having a problem with the flow of data between the structures of the case.

  I try to use an example of a state machine for this simple problem. but when I try to send data of a box structure to change the State of the code. It will change not in the desirable output, instead, it offers the possibility that the exit options emul.

  could someone please point what I'm doing wrong here. Any kind of help would be very appreciated.

  With a quick glance at your photos a question you have is that you use not data flow. You write your status updated in local variables value. Your State should pass through the case structures are a single wire. Playback of your order "Enum", happened in the register shift on the right side of your loop probably get running and reading before any processing occurs within the structure of your business. That's why you're reading the old value of the State and not the update. or have a classic case of a race condition in your code.

• Data flow problem

  I tried diligently to understand and implement the correct data flow in Labview. I have a slight problem, now that I don't understand. While inside the loop internal (while loop) and data acq is running, the program does not query the capture button so it will hang in an infinite loop. Since the acquisition of data is configured to read a single sample, my logic says it should do exactly that and query button. I use that as a DAQ simulated at the present time, no hanging physical Board card. May this be the problem? Or is my simply wrong flow data?

  There are a few problems.

  • You don't need a wait in a loop that has a structure of the event.
  • Your case of timeout is not necessary, he asks basically just the back button. Best is to create an event for the back button.
  • Yes, what's good is a structure of the event if it is blocked with an inner loop of maintenance events. You can use the outer loop for everything, it can turn plugs as well through the timeout event.
  • You should have logic to prevent the capture up to this as configured.

  Attached is a quick project on how you can change things. Because I don't have DAQ, I can not test, so there are probably bugs. However, you should be able to see the main ideas.

  Let me know if you have any questions.

• data flow problem, queuing Subvi primary VI

  Ive stuck on a very simple data flow problem here, I would like to convey the data queued in the Subvi and dequeue in the main loop of the vi consumer. Ive attached the vi, since im already stuck on this problem, I was hoping I could learn a few things, especially implementation action engine in this situation

  Thank you.

  Your Subvi makes no sense since your loop will always leave after the first iteration and you always initialize your counter to 0 whenever run you it. This is a problem.

  Your code also suffers from several places that are made by the queue data. You will get undeterministic behavior since you do not know which dequeue will get the first data. In general, for a producer/consumer using the architecture queued one or more loops loops should be given enqueueing to the queue. A single loop must be made of data. These loops shuold run in parallel to each other. In your code, you can only run your Subvi whenever you press the Start button and as said you will always show the value 1 to the queue. What you need to do, is to have your Subvi managed independently once it is started. Use "Start Asychronous CAll" to start your Subvi when the Start button is pressed then let it just run. Have it post the meter to the queue. Your lower loop in main VI should remove the values and display them. You need not wait in this lower loop since it is the purpose of the dequeue. This loop will be inactive if there is no current data and run only when the data is in the queue.

  In the upper loop of your VI main remove the dequeue and the queue. You don't need them as the Subvi is all that is necessary to validate the data in the queue.

• No dialog boxes of Bank of information on data flow diagram

  I upgraded from data model 3.0 to 3.3.0.747, but now I'm having problems creating data flow diagrams.

  Previously, I select the "InfoStore" or "Process" or "External Agent" icon and click on the diagram to create a new object.  Double click the new object would open a Properties dialog box and I would be able to enter information from here.  This always works for the external Agent and the process, but the information never store opens a Properties dialog box.  I tried to find it elsewhere, but I am currently at a loss on how to enter this information.

  Any suggestions?

  Hello

  It seems you have a problem with the content of "system directory set types" in the preferences:

  C:\Users\anne.haak\Documents\Oracle SQL Developer data Modeler\mywork\systemtypes

  You can copy the contents of the default system directory - here it's in your installation of DM datamodeler\datamodeler\types. Or at least you must copy types.xml.

• Lose the mapping source-target of a process of data flow diagram

  Hello
  
  When I reload an xml repository model design, I lose mappings of source-target of a process of data flow diagram. I wonder why.
  
  The way it goes is:
  -Define a flow diagram data banks of information, processes and workflows.
  -Information structures are defined on the workflow and information reflected down to the processes and stores information.
  -In a process, I defined mapping Source-target by selecting a target element, and then by selecting the source element.
  -J' I save the entire model.
  -So far, the mapping of the Source-target maintains the link between the source and target.
  -If I leave Modeler data, next time I reload the saved template, the mapping target Source-target associations to elements of source are lost!
  
  Someone there the same question or do not know how to solve?
  
  Thank you
  
  / Mario

  Hi Mario,.

  There are a few errors in the definitions of meta data and you can change them - are located in datamodeler\datamodeler\xmlmetadata directory.
  (1) bad method is used in the definition of Process.xml meta data file:
  

  getter = "getUpdatedTargetElements" should be replaced by
  getter = "getTargetElements" and it works

  also, there is an error in TargetElement.xml

  getItemByID = "getPartyByID" should be replaced by
  getItemByID = "getSourceByID."

• Shared photos showing the data flow but it is off

  Hello

  My phone keeps telling that storage is almost full and when I went into settings - storage - and camera is that Shared Photo Stream uses 4 KB. I don't even have Shared Photo Stream active... anyone know how to find these photos or how to remove the data used? Thank you

  Hello monkeyface0508,

  Thank you for using communities of Apple Support. It is my understanding that photo stream is too much space on your iPhone 6 sec, even if you do not use. I know how valuable storage capacity can be on any device. I want to ensure that your data and storage are accurate.

  Given that you have confirmed that the photo stream is turned off, I recommend you to restart the phone. This can solve many unexpected behaviours. Follow the steps below to restart.

  1. Press and hold the sleep/wake button until the Red slider appears.
  2. Drag the slider to turn off your device completely off.
  3. Once the device turns off, press and hold the sleep/wake button again until you see the Apple logo.

  Restart your iPhone, iPad or iPod touch

  In addition, check your Photos app to see if there is an album of Photo Stream shown. Please use the link below for more information on checking your storage space.
  Check the storage on your iPhone, iPad and iPod touch

  Have a great day!

• WLan connected to the Satellite U400 PSU40C but no data flow

  Hey guys,.

  Hope you can help me with a problem I have with the wireless to my new laptop. I bought a Toshiba U400 PSU40C-08U01C.

  It came pre-installed with Windows Vista. Everything worked fine out of the box, wireless/Wired internet.
  I really didn't want to run Vista, so I formatted the hard drive and installed a new installation of patches to update w / all WinXP to SP2 (haven't tried the SP3).
  I managed to install most of the material on the laptop, all drivers worked well.

  Wired connection worked flawlessly - Marvell Yukon network card.
  However, I came across a problem with wireless connectivity. The map has proved to be an Atheros AR9281-AL1E (discovered that by running Everest Home, held a diagnosis on the machine).

  I found no drivers on Toshiba Canada site, since they are all INTEL drivers and do not work to install the drivers for the network card. I was able to google and get drivers for model AR9281 wireless. After installing, everything seemed to be good.

  The WLAN had no problem installing with this driver, I used windows to manage the wireless. I connected to my network w/WPA wireless security. He got a good IP and default gateway appropriate... but NONE GIVEN don't FLOW! Couldn't BACK out ping, was not able to surf. Could not access the home network, could not connect to the router. I know that's not the router, since I went back to cable on the laptop - worked well. Also the without wire is good, because I have two other laptops running smoothly.
  He was also a clean install so no security except for windows firewall software that has been disabled.

  Someone at - it had a problem similar to this? I will return to the Vista installation with the recovery disk and see if I can somehow find out what drivers he used to install the WLAN network card. If I can't get this to work, I can also install Ubuntu and try installing the WLAN network card it and see if I have some luck. Hoping someone can offer other things I could try.

  Thanks in advance.

  Hello

  It's really a good idea to install the recovery image again to see if the wireless card is working properly. Please post the result.

• Notifier breaks the normal data flow behavior

  This is another one of those questions to notify... I would be grateful if someone could explain to me what is the problem with the attached VI (LV2012).

  When you move the cursor, I get different readings on a single thread that is just the synchronization of data with the release of a notifier flow. In particular, there is a notifier 'normal' that feeds a loop that works as expected. The declarant "spooky" is used to trigger the display of a value of control indirectly. If the notification output is connected to the structure of sequence, it produced uneven results in out1 and out2 (or probes on this thread). If this thread is removed, it works as expected.

  The cable slider to out1 and out2 seems to keep 2 different values without any given obvious flow condition or the time.

  Thank you

  Dirk

  Race condition.

  In your second loop, the cursor is read before the author of the notification is sent.  So, it will always be 1 iteration behind.  By wiring up that boolean to the structure of the sequence, you declare that the indicator cannot be updated until that a notification is received.  And given that this slider value was read before that the author of the notification has been received, the indicator will get the value of "old."

• TCP data flow is interrupted by recording data (text entry)

  Hello, I am currently working on a senior design project where my team is currently developing a control system for a small wind turbine. We are adding sensors and wireless systems to the turbine. The sensor data will be collected and sent over a TCP connection. The Labview will serve as the listener and display the values on the web.

  I have problems with the registration however data.

  I would like for where you put in the time, you the datalogger to be active, then press a button and the data logger records the incoming values on the TCP connection and create a CSV text file.

  Whenever the loop of data logging is running, stops the flow of data from the sensor so all my recorded values are the same for the duration.

  Any input would be appreciated.

  Thank you!

  
  

• NSX data flow

  I have a few questions about this diagram that I hope someone can answer.

  

  When the controllers communicate with ESXi hosts is the vmk0 (Mgmt) interface or interface vmkX (VTEP) on the hosts?

  Guess it is the vmk0 interface (Mgmt) and if this is the case is I ANY communication between the vmkX interface (VTEP) control plane on host computers and components of the NSX (Manager, controller, edge etc.)?

  In addition it is VTEP only VTEP communication for the data plan?

  The flow of communication is between the officers on the ESXi hypervisor to/from the controllers and the Manager via the management interface.

  This document details the agents:

  https://www.VMware.com/files/PDF/products/NSX/VMW-NSX-network-virtualization-design-guide.PDF

  This KB details the ports requirements for NSX:

  VMware KB: Network for VMware NSX for vSphere 6.x Port requirements

  VTEPs communicate with the other VTEPs.  The concept of the plane of data includes more than just the VTEPs.  The design guide offers more detail on this topic as well.

  BOM Dia reach,

  EU awesoe o than você hoje seja isso aqui (Desenho bem simplificado) has:

  

  Hoje o as voce tem e o Aplicativo Medidor + USB Driver controlando o seu medidor. Básicamente, sua aplciacao esta dividida em camadas very:

  • Size- Wave are as funcionalidades reached programa (interface com o usuario, dados Apresentação, Geraçao of archives, etc.)
  • VISA - Location Software Uma para appropriate control. Básicamente, ele to communication com o USB Driver para poder enviar e receber dados do barramento USB through pacotes.
  • Device driver - Intrucoes SW of baixo nivel para um Periférico um barramento through control.

  No desenho, EU aponto duas camadas wave voce pode atuar para automatizar try suas medicoes:

  • Size- Você pode usar o VI Server para o Aplicativo do Medidor control (Se este aplicativo sido em LabVIEW, o as EU suponho ser truth get lost). No e Chipre sword however is o desenvolvedor don't do produto permitiu isso (Veja using VI server to transmit data between a VI and an executable of LabVIEW). Outra alternativa e com o manufacturer to see Ali's ele desenvolveu any API (Application Programming Interface) para as voce o instrumento diretamente control win.
  • VISA - O LabVIEW Fornece uma API called NI-VISA para poder enviar e receber information through several barramentos (Veja Series Instrument Control Tutorial)

  E possible access pilot diretamente also o, mas had nao recomendo. O resultado não compensation o esfroco!

  Espero ter esclarecido suas doubt e espero that voce has sucesso na sua application!

  Atenciosamente.
