• This LabVIEW programmer needs to know

  Hello guys...

  I'm working on labVIEW for 1 year last on mine.

  If I have problems I will post my questions in the Forum of NOR.

  But I don't know that a small drop of sea water...

  So what should a labview programmer should know?

  In short, how avoid the 10 screen wide spaghetti complete code of the structures of the sequence, local variables and the race conditions

  Also I advice take you a look at the certificates of NOR and the "learning curve":

  Edit: perhaps, I would just add a few points that I usually have to keep in mind during the phase of a new project of planning:

  • Choose the right framework or model based on requirements
  • Keep in mind how to get and set values - indicators and controls. If possible, use the cable to transmit data. Keep in mind what's OK to do with local variables (for example updating a control), and which should be avoided (usually) (read/write indicators for example). If you cannot use the wire to go directly to information (parallel loops), learn the correct use of notifiers, queues, UserEvents, etc...
  • who will use the code (it is very important, you need a totally different approach if you develop for yourself, or others who are not programmers and perhaps even do not know the physical part of the system...)
  • GUI always be responsible. Avoid bad habits (longer time running things in the GUI event loop).
  • Avoid the overcrowded façade: use pop-up windows for the settings, etc. That the user don't need to see always.
  • Error handling! It is very important to make a robust error handling strategy: for example if one of your HW components creates an error, your application cannot just stop everything. Handle the error, close properly all HW and file references (do not forget if you don't properly close a file, you can lose a LOT of data : file write is buffered memory RAM). Also record the error information to a log file.
  • If you need to make an EXE or installer: use a configuration file to store the user's changes: If the user changed the colors (width, etc.) a chart/graph, store this information in a configuration file that you load at the next startup of the application.
  • Automatic detection equipment (or users the possibility to modify the port/channel): what happens if your application moves to another PC (numbering changes COM port, etc...)? Your application needs to adapt to the changes of HW.

• How will I know that I'm good at labview

  I am Sarah, I learned labview of my second year, I attended numerous workshops directed by NOR, also made projects in image processing, signal processing plans also to Maxeye technology solutions, also associated with LabVIEW all possible aging gets solved by me and my friends wvwn of teachers to students, but still I failed to CLAD Exam so what can be the problem... I feel terrible to me... Please help me find what would be the problem...

  Thanks in advance...

  The CLAD review is entirely based on the content of the course 1 Core and Core 2 - If you have not done these courses you can have some gaps in your knowledge for what is required to pass the examination. Maybe you know how to solve the problems in LabVIEW, but your style is not the way of "NOT recommended." It also depends on many other factors such as the amount of preparation you have made under consideration - did you sample exams? Have you had those? To go through the preparation of examination materials?

  The certification is only one way to show you are competent to LabVIEW - your experience and roles/jobs/projects earlier also count for a lot. I know many programmers LabVIEW which is good to LabVIEW, but have never sat all certification exams.

  There are many experts LabVIEW on these forums - you can still view the code you wrote and maybe they he would see. They would probably be able to give you feedback on what level you are.

  Edit: The jury of the certifications on the forums is a good place to discuss the examination for certification - you can post here if you have had problems with the sample tests or the parts of the exam and even begin a review CLD model (which is a practical review of LabVIEW programming) and post your control solution.

• 2012 LabVIEW Eval/training MVC tutorial must IMAQ but Vision must LV 2011 installed in order to install.

  I'm using LabVIEW 2012 evaluation of training mode in order to find a location using LabVIEW. A MVC tutorial looks like a very good example and I can open the first VI, Starter.vi of MVC, but when I try to open the project which includes screws to MVC OOP advanced with controls and Factory.vi, it must IMAQ live but when I try to install Vision in order to get the screws IMAQ, it needs LV 2011 installed in order to install the Vision and will not proceed with the installation of Vision/IMAQ.

  After searching the site OR days to get responses LVOOP I found this tutorial that could be useful, if it's actually working.

  Setup of Vision should probably work with 2012, but the installer was not setup to work with 2011 or later.

  In addition, I have not found a good description of what the MVC "framework" is all about.

  I used LabVIEW since the beginning of the 1990s, but not from my NI Suite which included LV 8 and LVOOP about 2007. I desperately need a step by step "how-to and why ' for LVOOP, ACTOR, etc. I'm through the core I and Core II manual of training for certification, but it needed LabVIEW work as soon as POSSIBLE and do not have the $2,500 to upgrade my NI Suite or $10,000 for training or time to complete certification now.

  It seems that every time that I start to make progress and NI LabVIEW, I hit a roadblock. Nothing seems to ever work as announced.

  Help, please!

  First, you must determine what version of LabVIEW, you: 2011, 2011 SP1, 2012, 2012 SP1. You can find this by opening LabVIEW and navigate using-> on LabVIEW...

  Then, you download and install the compatible version of the Vision Development Module. Here is the link you should use:

  http://www.NI.com/downloads/products/ (search for Vision Development Module).

  In addition, there is a driver software that exists that is called Vision Acquisition Software. But, if you do not interact with the hardware at this stage, then you don't need it. Here's a better explanation:

  What is the difference between software Vision VDM, VBAI and going TO?

  About MVC, I'm no expert, but you should know what a MVC is and understand LabVIEW and characteristics before you dive into this example of MVC in LabVIEW. My recommendation is to not try to understand/learn MVC for the first time looking at this example. More information can be found by conducting a search on any search engine. Here is the Wikipedia article.

• Choose the right course of training OR + Certification

  Hello

  Hopefully, I'm in the right section of the forum.

  I have some basic knowledge of labview, I created, changed a few screws for hardware equipment such as glasses, food etc, that's when I worked as a trainee.

  Well now, I would like to go for certification OR beginners course (certified associate developer) to advanced (architect) and want to start taking my first step, I need some advice.

  I went through the training information available on the home page and a few questions,

  (1) these courses cover all specific application domain or is a general training, so we can have a bird's-eye view and then apply knowledge in a field interested as (material loop (HIL)), on-board etc.?

  (2) what level of course should start with?

  (3) I want to do an internship, which might be enough to eventually put me on a job in these tough times? What certification do I go to, how much time it usually takes to get enough experience and the examination of the basic certification, the Certified Associate Developerand other developer likeCertified levels and the architect?

  (4) I thought to do strong foundation by taking basic through training courses, OR mount on a project (if I find one) and develop skills in parallel while working and in preparation for certificate exams.

  (5) is there a test by which I could determine, what level I need to start with?

  I look forward to hearing from you of the people onboard, please guide me.

  No and truths don't discourge me :-)

  This might be a post immature, because I'm confused where to start with, please bear with me and answer me

  Kind regards

  Leo

  Hi leo,

  Yes it is possible. If you have spent enough time, then you can definitely get the knowledge needed to pass the certification. You can take the test online and you can print a few examples. There is also a lot of discussions in the forum about the questions and the answers.

  What do you mean with LabVIEW training? If you do a course, the course textbook contains the things you need for certification.

  It will be useful.

• How to force Thunderbird to accept a certificate? or admit a new certification authority where it does not accept authority as being valid?

  I get the following message when I check the signature of the shippers:

  This certificate cannot be verified and is not imported. The issuer of the certificate may be unknown or untrusted, the certificate may have expired or been revoked, or the certificate should not have been approved. »

  Then, after conversion of the .crt to a tent and .cer file to import in the list of the authorities - I get the following message: "is not a certificate authority certificate, so it cannot be imported into the list of certificate authority."
  I converted it by saving it to alternative formats, but it does not accept the authority of certification.
  I don't understand why Thunderbird won't let me accept the risk.
  Can I do this without getting the server of the sender address and port?
  Thank you!

  Ok. Roger all. Will try to get another certificate of the sender. Thank you very much!

• How can I become a FCPX certification if my country is not part of the training centre certified Apple

• Question about Certification WPA on Toshiba laptops

  How can one say what Toshiba laptops have available, in accordance with the certification of "https://certifications.wi-fi.org/wbcs_certified_products.php WPA wireless security?"

  Toshiba are unable to provide information on a particular model without a serial number. I'm considering a purchase, but I first need the WPA information.

  Concerning

  Peter

  Hello

  WPA encryption depends on the WLan card. If you want to buy one, then you should check if this books has one card Wlan.
  But how would I know which card was installed in the laptop without to know the name of the Toshiba laptop.

  The best way is to google for more information on the web.

  Do you want to know more about the Toshiba warranty?

• LabVIEW 2016 NI_ReportGenerationToolkit error

  I upgraded to Labview 2015-2016, but when you open one having previously worked for the project I now see an error in the NI_ReportGenerationToolkit.lvlib:Excel_Save_Workbook.vi.

  He tells me that the invoke node contains terminal unwired or bad.  However, it's a NOR provided VI and has not been changed between updates. Please let me know if it is a solvable issue.

  Take a look at this thread.

• DAQ Assistant is not in LabView

  Hi all

  I use NEITHER cDAQ-9174 and NI 9203.  I have already installed the driver for the NI 9174 cDAQ, which is NEITHER-DAQmx 9.8.0.  I can see the device when I opened NI MAX. However, when I open LabView 2015, I can't find DAQ Assistant in the function Palette. I noticed on the chassis, 'ACTIVE' light is not on while two other "POWER" and "READY" light is on.  I look in the forums OR but I can not find the solution.

  Any suggestion, please help!

  Thank you!

  DAQmx 9.8 is not compatible with LabVIEW 2015.  You must use at least DAQmx 15.0.  See here for more details: NOR-DAQmx and LabVIEW compatibility

• LabVIEW FPGA SPI accident - SPI OR IP address for example - R series OR

  Hello

  I am trying to run the series R - sample project NI SPI FPGA Simulation.lvproj that comes with the SPI IP OR on a real FlexRIO FPGA SMU-7976R target with an attached digital adaptation NI 6581 B Module. The example is for a PCIe-7841R but I wore during my target FPGA, follow these steps and made additional changes to try to make it work with my set-up. I learned that FlexRIO FAMs CLIPs do not work with nodes in office had so I know I can't simulate the project originally planned so I will try to use FPGA to e/s node host side (open FPGA vi reference) to implement the actual hardware.

  My first question concerns my configuration of the adapter module e/s and selection. I added the IO Module (NI 6581 B: NI 6581 B channel) for my project and selected the channels as shown in the table below. I have a real physical hardware connection as described below using two NI SHC68-C68-D4 cables and a break-out Board.

  

  I changed the names as well:

  

  I selected these DIO channels because I wanted the DDCA connector to be the master and the DDCB connector to be the slave. In addition, in this CLIP every eight channels of i/o has a write enable signal. I have not used the Port configuration because I needed 4 available DIO channels and I saw DIO0-3. Is my logic of selection of channel vs correct Port here?

  Following the same strategy that examples FlexRIO/NI6581B, I changed the FPGA.vi to include initialization outside of timed loops:

  

  And in the Host.vi I have a node reference FPGA and wired loops of feedback accordingly:

  

  When I compile the FPGA and try to run Host.vi LabVIEW inevitably crashes with Crash Reporter below and must restart:

  

  Does anyone know what I'm doing wrong here? My guess is that it has something to do with the CLIP/IOModule. Any help is appreciated.

  Thank you

  Scott

  Hi Scott,.

  I suspect that the problem might be related to the fact that your node open FPGA VI reference is in the while loop and trying to open a new FPGA reference at each iteration.
  If you move outside of the while loop, it does not solve the crash?

  On channel vs port question, your logic seems reasonable to me, but I recommend to try it since this feature could depend on device.

• LabVIEW 2014 does support CDAQ 9136

  I use LV 2014 SP1, I wanted to buy CDAQ 9136 Windows controller for one of my projects. I'd like to figure out if I can use the SP1 of 2014 LV with DAQmx15.1 in the program for this controller? User manual CDAQ 9136 does not say anything on the support of LV, just said that DAQmx 15.1 is supported.

  When I tried to add a target CDAQ in SP1 LV2014 with DAQmx15.1, it does not show the CDAQ 9136. I won't use the real time of the CDAQ 9136 version, but I'm confused. Any help would be greatly appreciated.

  

  Nanda,

  I would like to clarify the compatibility for the NOR-9136. It is compatible with DAQmx, starting with DAQmx 15.1. In other words, it can be used as a normal cDAQ chassis in any version of LabVIEW with DAQmx 15.1 or later installed (within reasonable limits). However, compatibility in real-time with the cDAQ-9136 has not introduced before LabVIEW time real 2015 module, which is only compatible with LabVIEW 2015. Thus, to use the cDAQ-9136 as a real-time controller, you will need 2015-LabVIEW and the module time real LabVIEW 2015 or later. This note can be found in DAQmx 15.1 notes for supported devices.
