• Frequency of calls to control for the FPGA read/write

  Hello

  I use a cRIO-9076 with a module NI 9476 DO spend some faucets. It is sometimes necessary for faucets with a pulse time down to a few ms of impulse.

  The FPGA VI Gets the power tap queries, executes a logic of security, and routes the numerical results for the exits. It gets applications power of the VI on RT target that uses the function ' Read/write FPGA control' interaction programming of the FPGA VI front. The loop on the RT runs with 1 kHz, no iteration is missed. That means, it should be possible to switch the valves with a resolution of 1 ms.

  What I see on an oscilloscope, is that the output digital are high for multiples of 50 ms, the system does not reach the valve for example 80 ms pulse or pulses shorter than Ms. 50 is a kind of limitation for calls of "FPGA read/write control"? I tried both options for arbitration, but it does not help.

  The best knowledge of the limiting cRIO/module/features or ideas? Thank you in advance.

• Cannot access the card reader/writer internal Flash

  After a few updates, I can access is no longer any SD card inserted into the card reader/writer Flash. I tried to use the convenience store but just that said there is no problem found. When I insert the SD card, it appears in the 'control Panel\Hardware and Sound\Devices and printers' as ' Flash Card Reader/Writer "but I am not able to access the card.

  Hi Tim,.

  Was there a card player offered to you via Windows update driver update?

  -You see no drive letter assigned to the flash card while you see for readers in the window 'computer '?

  -What is the error you get when you go to the map?

  I suggest you try to change the drive letter assigned to the card and see if that helps.

  1 type diskmgmt.msc in the RUN prompt or in start search to open the computer management window.

  2. right click on the indicated card device and select "paths of access and change drive letter.

  3. click on change if there is an assigned drive letter, and then change to another letter. If this is not the case, click on add and select a drive letter.

  4 restart the computer so that the changes are applied and see if you are able to access the content in the map.

  For more information: http://windows.microsoft.com/en-in/windows7/change-add-or-remove-a-drive-letter

  Alternatively, you can try to uninstall and reinstall the drivers for the card and see if that makes a difference.

  Visit the website of your computer manufacturer to download and install the latest drivers.

• Configuration required to use the fingerprint reader

  I have a dv6tQE delivered later this week and I'm looking into how to configure the fingerprint reader.  I'm interested the FR for projecting my fingerprint with the plethora of passwords that I now keep in a Word document hyperlink.  Too much memorize.  I'm not interested in the security feature that requires a logon or a fingerprint whenever I start my computer.  I usually push on the button and then perform several tasks to something else and come back to the computer, wait until it is ready to roll without the need for an additional activity on my part.

  The User Guide PDF downloaded States in part:

  "In order to use the fingerprint reader, you must configure a user account with a password on the computer. This account allows you to log on to your computer with a simple touch of the designated finger. Alternatively, you can use the fingerprint reader to fill in the password on Web sites and other programs that require a login. See using the fingerprint software for instructions. After you have created your identity from fingerprints, you can configure single sign-on... »

  It will be necessary for me to set up a user account for my login or can I skip that part and use the NOF for passwords only?  In addition, there is a link to the FR software guide?

• If I use the adobe reader 7.0 software to open LiveCycle Designer ES2, what will happen?

  Hello

  I intend to recommend adobe LiveCycle Designer ES2 as a software designer of forms for a client company. But it seems that the client always uses the old version of adobe reader 7.0.

  So I need to know that it is essential to use the adobe reader 9.0 for designer ES2 software and if Adobe reader 7.0, this problem would happen?

  It is very useful, if there is detailed information on this subject.

  Thank you

  Shoku en

  Hello

  When you design a form in LC Designer ES2, you can set the version target of Acrobat/Reader software in the file > properties > default values tab.

  

  While you can target v7, be aware that some features in LC Designer ES2 is not supported in Reader v7. For example in LC Designer, you can define the presence of an object "(screen visible only)", but it is not supported in Reader v7, so would cause a problem. So for each form you will need to set the version of the target, and then check the warnings palette to see if there are problems.

  See the post by John Brinkman discussing Acrobat X, as it's a very handy table for the versions of the specification of the designer/XFA LC and Acrobat/Reader: Acrobat X and XFA 3.3

  XFA Version	Acrobat/Reader
  2.1	6.02
  2.2	7.0
  2.3	7.0.1 7.02
  2.4	7.0.5, 7.0.7
  2.5	8.0
  2.6	8.1, 8.1.1
  2.8	9.0
  3.0	9.1, 9.2, 9.3
  3.3	10.0

  You can see there are a lot of changes around v7 and if the user has v7.0.7 Reader, you can use the features of 2.4 XFA specification.

  The other question to know is that users with the player will NOT be able to save data in the form, UNLESS the form has been enabled for reader until the form is deployed.

  The form can be active player in two ways:

  • Using Acrobat Standard v9 or Acrobat Professional v7 or v8. A license restrictions, see the EULA.
  • With the help of a server product called Adobe LiveCycle Reader Extensions ES2. Extra charge.

  Here is a summary of the options available for users with the player, depending on whether the form is activated to drive AND how she has been activated:

  

  There is a post here and a summary in PDF:

• Effective use of the FPGA read/write

  I am writing an application for a CompactRIO real-time and I am looking for ways to simplify my code and reduce the CPU usage. I use FPGA to do much CAN e-mail and signal processing, then I have a VI running on the real-time processor that reads values in the FPGA, does some processing and outputs data in the FPGA. My code running on real-time parallel uses several loops running in a master/slave architecture. A single loop reads all necessary information in the FPGA in indicators and writes the values of the controls in the FPGA. The other loops read entries and manipulate the outputs via local variables.

  My question if it would be more effective to get rid of the loop which is dedicated to the communication of FPGA and has of each loop to read and write directly on the FPGA. If I use a reference block FPGA open and use the reference of the output in several loops, each read/write operation block others until it's over? Each output is changed only in one place in the code, but there are several entries that are used by multiple loops. It is even more effective for each loop of read/write for the FPGA on request? How will this affect determinism?

  Thank you

  Jon

  Jon,

  Read/write controls is not deterministic, but I think that your previous method should work just fine, as long as you have that unique writers. If you have multiple writers, you start affected by race conditions.

  I don't think you will see a significant improvement in the performance/CPU in the alternative method. You would see big performance gains if your master loop reads more slowly indeed, but it's always a compromise.

• Problems using the event to write new parameter values to VISA structure

  Hi all

  I created a VI to read an Omega flow meter. It is possible to change setpoint (setpoint (0-2) SLPM) of the meter and the gas (O2, CH4,...). To read instrument I write its ID (A-Z), followed by a carriage return, for example: A + 0x0D

  I created a VI with the events to write only the parameters to the instrument when a value is changed. My VI works but from time to time, it does not write the parameter change (gas or set point). I think that is has something to do with the while loop containing an entry VISA.

  Open FMA contains parameters and VISA opend

  Case of timeout initialize writing gas and setpoint for the first time

  Other events are for the change in the value of setpoint and gas

  How can I make sure that any change of setting will be writtent the instrument?

  Thank you

  Salvation Bass,

  Well, it is true that I lose this way time-out feature.

  No, you do not lose this feature. You put in a different position.

  You must call it BEFORE your loop!

  I'm not sure that I am following on this one there

  Why are you not sure? You have a large number of constants "0d" and it would be great to see that they are displayed in HEX mode instead of the normal display mode.

  The new VI manages events sometimes... but sometimes, missing a few changes... I think it is because there is an entry in the while loop. Do you have any idea how to prevent this?

  Never, NEVER use parallel loops to write and read on the same device on your serial port!

  How do ensure you that you always get the right answer to your order sent before?

  What is the purpose of using a second loop here? A loop with no wait States?

• Error 200088 using the DAQmx reading VI in a case structure

  Main problem: I'm writing a VI that will read data from a data acquisition and write to a text file when I hit a button "registration". To do this, I use the VI of reading DAQmx in a while loop, which is located in a case statement (I hit the 'Save' button for the case of true), which is in another while loop. My DAQmx create Virtual channels screws are outside of the loop, so a wire goes through three structures to connect these screws to the VI DAQmx Read.

  After clicking on 'Save', my VI works until I hit the "Stop" button, how I get error 200088: ' specified is not valid or does not exist. " If anyone can help me get rid of this error, that would be greatly appreciated!

  I enclose my VI and an image of the error.

  Secondary problem: currently, I use two different DAQmx read live: one mentioned above, which lays down: after clicking 'Save' and the other who reads data continuously to display on maps. I want to combine these two, but I don't know if this is possible given the case statement.

  Thank you!

  Hi Alexwright,

  I made some quick changes to demonstrate the producer consumer loop that would be effective in your case. You want to loop of producer in the first while loop so that you use and the same closing DAQmx task. Moving a forwardthis will require some trial and effective change for your application. Please also make sure you use our debugging tools: http://www.ni.com/gettingstarted/labviewbasics/debug.htm.

  I hope this helps.

• Spectrum Analyzer (Keysight PXA) get the Trace using the binary format

• Make the NTFS read/write permissions without possibility to create/delete folders

  Out to one of our sites, we have a server running Windows Server R2 of 2012 which took a file share accessible to our people on the spot. Our project managers have developed a very strict folder for this file share structure, and for the purposes of verification, they want to stick to the closer this structure as possible.

  Therefore, although the local people must have read/write access to create, edit, and delete files, they won't they are able to create or delete folders. They want to use the existing folders and not to store stuff in folders that nobody knows there is except for the person who created them.

  The closest way to you, I got to do is to uncheck the advanced permissions "create folders / adding data" and "Delete subfolders and files." This has some side effects, however, the most notable being the inability to add data to the files, some files (such as CAD drawings) can be changed by anyone except the person who created them.

  Is there a way using only the NTFS permissions to accomplish what the project leaders? And if not, are there any third-party utilities that will help us do this?

  Thanks in advance for any help.
