Point of Modbus DSC read does not correctly

I use 2013 LV 32-bit on W7 64-bit.  I talk to an industrial controller with Modbus to Ethernet.  My current software uses the interface modbus DSC, in which I define the bus Modbus itself within a library in the project, and then set each point Modbus as an address within this definition of modbus.  Inside LabVIEW, you can then get the data Modbus via shared Variables.  I am currently using the dynamic variable calls shared, rather than static variables shared.  I have points that are Boolean (coils) and real, with a read-only and a read/write.  In general, it all works.

However, there is a real read/write that acts funny.  If I put a new value, or the industrial controller assigns a new value, the industrial controller Gets the new value.  Variable motor shared on my computer gets even the new value, as can be verified by opening the Distributed System Manager.  But LabVIEW continues to read the old value, without error.  Other points of read/write work very well, and I have looked on the definition of the address several times and cannot find any reason why this should be different than the others.

Does anyone have any ideas why DSM sees a new value of a shared variable, without LabVIEW continues to get the old value?  I watched the init for the dynamics of SV case, and I see all the options I can change to try to solve this problem.  My next attempt will be to rewrite the entire auxiliary system so that it uses the most recent Modbus Library of NOR and ignores the whole thing of DSC.  It will be probably much better for other reasons as well.  I noticed that with DSC and the shared Variables, the first time that the program runs it starts fairly quickly, but subsequent executions can take up to two minutes to connect to the SV.

Thank you

Never mind.  I think I found the problem.  A bug minor configuration in my own code...

  • Smart card reader does not correctly connect once the virtual machine is restored from sleep using the vmrum controls

    Smart card reader does not correctly connect once the virtual machine is restored from sleep using the vmrum controls

    Scenario is,

    1. smart card reader is connected to the VM with card inserted in

    2 initiate a prompt suspension of the VM toolbar

    3. now to resume the virtual machine by using vmrun command into the host machine

    WS t vmrun start xxx.vmx

    Now, the recovery of VM but the smart card reader that was previously connected does not work properly in VM that is to say, sometimes after CV chip card reader driver is uninstalling and a few other times, chip connected to the drive is not available on a virtual computer

    My requirement is after power, smart card reader can stay connected to the virtual computer with the already installed driver and the smart card.

    Kindly help with this problem.

    Thank you!!

    Dear all,

    I had a work around for this problem. By adding "usb.autoConnect.device0 ="0xVID:0xPID"" this statement to the VMX file, solves this problem, that is, whenever the VM is wake-up by clicking on the link CV or using vmrun commands, it connects the unit in question automatically and it is charging correctly with his driver. Obtaining smart card detected after sleep\hibernate with no problems.

    VID & PID is respective ID of the device that can be seen in the properties of the Device Manager "Device Instance path".

    Hello

    I don t think that a disk cleanup would solve this problem. You can try to clean the lens but I m with skepticism.
    If you want to buy a car, please be careful. You need a compatible player and supported.

    Some readers are set to CSEL, master or slave. It is very important that you buy a disk with the right settings.

  • LabVIEW csv file reading does not correctly.

    I try to use the spreadsheet read vi file as follows the attached csv.

    He did some things wrong:

    (1) the first cell in the resulting table has ÿþ attached to the front of it, it looks like labview is striking some special characters, it should not? (Notepad, notepad ++ and excel can open all the file with no problem and no show ÿþ or something like that).

    (2) it is abuse characters from end of LIFE as two line breaks, resulting in empty rows between each row of data. (Looking at the csv file in notepad ++ confirms that the lines are completed with a CR and LF (same as EOL).)

    (3) I read in sub form of string, because one of the columns is nonnumeric, but then I remove this column of and try to convert the remaining string table in a digital picture (failure). It also fails if I shoot an individual element of the array and try to convert it to a number (in either case, using the string fract/exp number), below, I have an example of attempted to read from the 2nd column of the 1st row (index: 0.1) which is being shaped as a string: "1.37238168716431" and conversion which gives 0 as you can see in the snapshot of the façade into a number.


  • Flash HTML document read does not correctly... HELP Please

    Basically, I have a lot of text that contain underscores and everything good put things in form that the flash text cannot do. So I created a dynamic scrolling text box, loaded externally document txt containing all the right HTML tags for flash. But for some reason any flash cut the text. It will not show all the text that I have. I noticed that it seems to be cut off in SOME areas (not all) where I have a hyperlink. Someone at - it never deals with this before? He drives me crazy and I can't find ANY help online about it. If you have any suggestions, I'd be super grateful! Thanks in advance

    the ampersand is used by flash to indicate the beginning and end or a text variable/value pair charged.  for example, when you use an ampersand in text loaded you should encode.  26% is the correct encoding and that's the difference between your code and the code that I have proposed.

    I have a HP ENVY 15 t-j100 Quad Edition running Windows 7. His card reader does not work. When I insert an SD card, I get a message that the device is not installed correctly. Windows prompts you to update me the driver, so I let him, but he can't find the driver. In devices with SD card inserted, Manager it shows a symbol in the "Other devices" section "hard drive"with a yellow "!"  The State of the device reads:

    You are the very welcome!

    Oh... It's big, happy that the problem was solved after recovery

    It would very probably be updates of Windows.

    Try to create a system restore manually each time before performing any installation of update or something important. You can restore to a previous restore points you have created, if a problem occurs after an update.
    http://www.SevenForums.com/tutorials/697-system-restore-point-create.html

    You can also create a shortcut to a button in your office so that you can easily create manual restore - Option 1 point in the following tutorial:
    http://www.SevenForums.com/tutorials/494-system-restore-point-shortcut.html

    System Restore: http://www.sevenforums.com/tutorials/700-system-restore.html

    I would also change the Windows Manual Automatic Update settings.
    This must be done in the HP support assistant program too - its control panel.

    I hope this helps.

  • HP Probook s 4540: fingerprint reader does not

    Hello

    Problem: fingerprint - Windows journal reader under does not have the ability to connect via the fingerprint reader.

    Overview: after installing the drivers of the fingerprint on the HP site and thanks to the HP protection tools to register successfully to fingerprints, I tried to log in via this method, but the Windows Connect screen does not display this option. Device Manager correctly identifies and shows the fingerprint sensor - however, the Control Panel does no detection of biometric devices.

    I really need help with this problem. Details of what steps I took trying to make the scanner work are given below.

    Specs:

    1) 4540 probook s

    (2) Windows 7 64 bit

    (3) i5 - 3210 m, 1 GB Hd 7650 m, 4 GB at 1333 Mhz, 750 GB 5400 RPM, VFS 491 fingerprint reader.

    Details of the problem and the steps of my work to install the drivers:

    After a new installation of Windows 7, I went on the site of HP driver to download the latest drivers for Probook s 4540:

    http://h20000.www2.HP.com/bizsupport/TechSupport/SoftwareIndex.jsp?lang=en&cc=us&prodNameId=5229457&...

    I installed the drivers in roughly in this order:

    drivers ethernet controller 1) realtek.

    drivers audio 2),

    (3) the chipset and USB 3.0 drivers (but not the Intel MEI driver)

    (4) Intel video driver: a problem such that the pilots were not allowed to install. After you disable switchable graphics in the bios, I was able to get these drivers to install.

    (5) AMD video drivers: installed after graphic driver intel HD - installed but Catalyst Control Center was not displayed. Then I reactivated switchable graphics in the BIOS, re-installed these drivers and CCC was now available.

    (6) support for HP keyboard shortcut

    (7) HP Universal camera driver

    (8) fingerprint sensor fingerprint validity

    (9) Synaptics Touchpad driver

    (10) Atheros wifi & bluetooth

    (11) Jmicron card reader

    After driver installation, I installed the HP protection tools. According to request a reboot of the PC, which I did-, he asked for the setting up security etc... Part of this pocess was the registration of fingerprints - successful. However, log off / restart of windows, an option to connect with the fingerprint reader does not appear in the Windows login screen.

    I open the control panel and found there wasn't that no biometric device only tab, even if the Device Manager showed biometric sensor, device and validity (VFS 491). I then uninstall HP protect tools and driver validity sensor fingerprint, and made sure that these services are running:

    -Credential Manager

    -Remote Procedure Call (RPC)

    DCOM Server process Launcher-

    RPC end point mapper-

    -Windows Biometric Service

    Plug-and-Play

    Then as suggested in another post on the forum, I installed first of all this:http://ftp.hp.com/pub/softpaq/sp55001-55500/sp55109.exe , then the drivers of the validity of 4540 s drivers page, then HP protection tools.

    After the reboot HP protect tools as before to register my fingerprints, but still no windows login prompt came to connect with fingerprints. However, a change after installtion of http://ftp.hp.com/pub/softpaq/sp55001-55500/sp55109.exe that has been in Control Panel it is now a tab for biometric devices. However, it is said that windows did not find it all installed biometric devices. A picture is attached showing the Device Manager and Control Panel!

    Please HP offer a solution. Thank you!

    OK problem solved. I don't know if it is related to the HP windows 7 system essential updates driver installation and Intel MEI or not - but I install these.

    What has really worked probably was it - > install the drivers of fingerprint and then the HP protection tools. Once rebooted, open HP tools protect, then return to the administration in the lower right corner-> the administration Console-> increase of security system-> tick windows login security and your done. Now, you will be able to connect through fingerprints registered.

  • Google Reader does not load

    Hello

    Since upgrading to Firefox 36.0.1 () and Google Reader does not load correctly. While I can access the page from disk, the color wheel that google appears as apps load just continues to run. I tried on Chrome and it loads fine. I also tried to open Firefox in Mode safe with extensions/add-ons disabled, as well as to empty cache memory. I have not yet tried the Firefox update, but I did not have any settings beyond the Add-ons that should interfere.

    Has anyone encountered this problem? Any suggestions would be very helpful.

    Thank you!

    Thank you! I just tried, and it did not help. However, I decided to do a "refresh" of firefox, and now it works. I'll follow careful of my modules and see if it happens again.

  • TS15g067cl laptop: memory card reader does not recognize the card

    The card reader does not recognize the cards.  It does not have a drive location (example: f drive).   This makes it impossible to veiw the files or photos on any (I tried six different) of my SanDisk SD cards.  I can't find anywhere to downlod corrected card rhe read updates update drivers or BIOS for my system.   I just bought this computer 1 week ago and do not understand why I read in the forums about driver issues of card reader for the last year.  Windows 8.1 has been out for some time.  Why HP would sell these computers without updating the software to make them work as they should?

    Thanks for the info.  Disk management does not show the drive.  The problem was resolved after reloading BIOS, as suggested in another post.

  • Satellite C850-B635 and Win7 - card reader does not work

    My laptop came with windows 8 and the card reader was not working
    but I installed windows 7 64-bit, downloaded all the drivers on my laptop, but the card reader does not work now.

    I downloaded a driver called card reader controller, but it did not work as well
    I don't know if there is a problem or there is a driver should I install and I don't know.
    Please help me solve this problem.

    In my windows Device Manager, these devices is not recognized:
    * PCI simple communication controller
    * SM Bus controller
    * Unknown Device

    I tried searching in my page to download drivers on the Toshiba Web site but could not find these
    Please help me make my card reader works again.
    Concerning

    Post edited by: domaking

    For me, the matter is simple, and the reason why the SD card reader is not working, it's just a driver compatible isn't installed.
    My theory seems to be correct, given that the SM bus controller and PCI simple communication controller appear in Device Manager and I suppose that one of these devices belongs to the player/controller of the SD card.

    I think that you should simply install this Realtek card reader controller that I found on the page of the Toshiba UE driver
    http://Support1.toshiba-tro.de/Tedd-files2/0/CARC-20130924161048.zip

    In addition, you must install all the other drivers Win 7 as well as Toshiba tools available by Satellite C850 series.

    Very important is the chipset driver, USB 3.0 driver (Win 7 has this port driver to control the USB 3.0), display driver. etc.

    Not very essential tools are Bulletin Board, product information online Reeltime, etc. This tools additional don t improved the performance of the laptop so its up to you if you want to use these software components

  • Why is one of my 4 5893 Modules doesn't work does not correctly?

    Hello

    This is the configuration of my HW and SW:

    LabView 2013 SP1

    1 x cRIO 9076

    4 x NI 9853 CAN Modules

    CAN0 - 1000 Kbps, entry timeout = 0, OutputTimeOut = 10000, Module clock: 20 MHz

    CAN1 - 500 Kbps, entry timeout = 0, OutputTimeOut = 10000, Module clock: 20 MHz

    I worked on a program for a test system, where each Module 9853 control two devices (CAN0 and CAN1), the same type of systems is controlled by other 9853 3 Modules in parallel.

    So basically, I use exactly the same functions for each module. So far, everything has worked correctly on module 1, but now that I started to test all other modules I have the problem that Module 3/CAN0 does not correctly read the information.

    While watching the FPGA façade, I see that each 10000ms one value is read, but only on that ONE module (frames are sent every 1ms from my unit)

    I tested the HW itself using the included examples and it works correctly, the only difference is that the example used only 2 Modules, one to send data and the other to receive it.

    I included my FPGA program as an image, I really don't think there is a problem with my RT SW, because all the other modules are working properly. Basically, my SW FPGA bed CAN Modules and puts the information in a FIFO, if there is an error (no information), it will make a loop once more and check again.

    Thanks for your help

    I solved the problem, it was an error of configuration on my side.

    The entry for Module3 CAN1 time-out was set up NOT as 0ms and 10000ms as I thought! , so that was my reading for DUT3 loop run only every 10000ms.

  • BlackBerry smartphones HELP! Ball control and keys doesn't work does not correctly!

    I have the curve 8330 and when I put in my unlock code and press the trackball, it acts as if im entering additional keys. When I finally get into the phone and try to press on the trackball, in its action, as if I am pressing the asterisk key. It does not correctly read the keys and is to register them as another key! Help pleaaase!

    This looks like what I've seen several times on a device with moisture damage.

    Even sitting on a countertop bath during a hot steamy shower or bath can cause problems with keyboard and trackball up to this JUST-withered.

    Really, it is more common than you think.

    1 the battery immediately! Do not turn on your BlackBerry device.

    2. allow the device to dry in a warm, dry place for 3 to 5 days * (see below)

    3. DO NOT "check it every day" by placing the battery in. Leave what would to dry completely. It takes time. Replacing the battery to check it can damage only (humidity + power = disaster).

    3. If the unit is hot after the drying period, let it cool to room temperature before placing the battery in the.

    * Suggestions on your BlackBerry in a warm dry place (open, with battery):

    • Place the BB in a container of dry uncooked rice, and then you can also place it in one of the locations mentioned below.
    • On top of all heat dry emitting electronic components: TV or CRT, LCD, TV cable box / Satellite or plasma monitor
    • On the dashboard of your car on a day sunny
