Wiring of connectors in LabVIEW 2011 problems

I've just been 'bitten again"by a wiring problem with a connector for a VI in LabVIEW 2011 (I've not seen this behavior in any previous version of LabVIEW to 7.0).

The question is this.  I (or one of my colleagues, who also noted it), run LabVIEW 2011 (August 2011 release), 32 - bit, Windows 7, 64-bit systems.  I have create a VI using the usual 4-2-2-4 connector of mires and connect the appropriate connector.  I save the VI, then drop it on a block diagram to use.

In another variation of this problem, the VI has fallen don't watch any connector or, if used to 'replace' an existing wired in VI with the same model of connector, "break" all the sons (because it has no connector when dropped on the diagram).  Reopen and reconsider the VI show that, indeed, the connectors are wired, but when I use the VI, the connector wiring is absent (the VI dropped watch without connectors).

In the second variant, all right, the connectors appear as expected.  But I then decide to move a connector.  I have open the VI to edit, make a cut of this Terminal and rewire to its new location.  The connector pane presents the new model.  But when I drop the VI on a block diagram, the connector is in its original location.

Restart LabVIEW, indeed restart the PC, does not change.  The only way to 'fix' this is to disconnect all terminals and a reconnect them.  A nuisance, to say the least, but also an obvious bug.

Has anyone else seen elsewhere?  I sent to OR, but it would be useful to know 'is it just me?' or not.  In my defense, I've seen this problem on several computers, all win 7/LabVIEW 2011.  I've also seen this with several LabVIEW projects.

I've attached a file with such a VI "buggy".  When you open it, you will see that the 'Length' indicator is wired to the top of the connector set page.  When I drop this VI on a new VI, however, the connector indicates coming out from the bottom!

I was told by an engineer NOR that this problem (a) is real and (b) has been fixed in SP1 release (spring) 2011 LabVIEW.  I have not had a chance to check this point, but (the trusting soul that I am), I consider that this problem has been a "Bug in LabVIEW 2011 that has been fixed in the SP1 Release"and therefore, I am prepared to mark this "resolved".

  • Problem with the configuration to use Silver Style with labview 2011 (32-bit)

    Hi my friends.

    I installed labview 2011 32 bits. I select money style my default control style. but when I create the new VI, labview creates no controls in the silver model

    the controls are created in modern style.

    can someone help me solve this problem?

    with all my thanks: Saeid

    If you're down by controls via the palette, then it will drop any type palette you are in.  You are most likely in the range of modern control.  The setting that you are talking about is when you create a command or the indicator by right-clicking on a primitive terminal.

  • Problem installing module time real LabVIEW 2011 SP1

    Hi, I'm new here. I have a problem when I tried to install LabVIEW Real - Time 2011 SP1. Whenever the part of initialization, this message appears: "NEITHER Labview 2011 SP1 32-nit must be installed before installing the OR labview 2011 SP1 real-time Module.» I'm sure that I've already installed Labview 2011 32-bit SP1 and it works well. I use a Windows7 OS and also have Labview 2010 and an older version of Labview 2010 RT module installed. I didn't remove the old version of the software, and I don't know if it is related to this problem.

    Can anyone help? Thank you in advance!

  • PROFIBUS in Labview 2011

    Hello

    I recently updated my Labview from 2010 to 2011. And then I tried to install the latest driver for Profibus (DF_PROFI_II_LV_1.36.2.zip) that I downloaded from (http://joule.ni.com/nidu/cds/view/p/id/2687/lang/en). Release date: 10/10/2011

    Normally, this extension must be installed to the location following (C:\Program NIUninstaller Instruments\LabVIEW 2010\vi.lib\addons). However, I did find it in the folder "addons" Labview 2011. There never to this question? To resolve this problem, should I just copy Comsoft.lib in the folder "addons" from 2010 to 2011? Something else I have to do?

    Thank you

    Zhi

    I t looks like that it detected the LV 2010 version as the current and did not install anything in 2011. You should be able to copy files on the same path mentioned.

  • FieldPoint for Labview 2011 W7 - 64 bit

    Hello

    I'm currently having problems running FieldPoint Labview 2011 on running on Windows 7 64 bit system. I installed the latest (6.0.9) FieldPoint driver which is compatible with 64-bit systems. However, when I try to make a simple program (see photo A). I met two main problems.

    (1) I'm not allowed to add a control, or a constant to the FieldPoint i/o Point in terminal (see illustration B). The option is grayed out.

    2) there is an error with the FPLVMgr.dll file that is used by virtually every necessary .vi for FieldPoint (see picture C)

    I'd appreciate any help. If you need to know the application, I have a Thermocouple cFP-RTD-122. I'm trying to implement a simple program to read out temperature (see picture D). E PIC shows my MAX.

    Thank you!

    Juan

    Hey Juan,.

    I see you are using 64-bit Windows, but you use a LabVIEW 2011 64 bit as well?  FieldPoint runs on a 64 bit OS, but does not work in the 64-bit LabVIEW environment.  I would recommend installation of environment 32-bit LabVIEW and go from there.

  • LabVIEW 2011 compiled the application crash

    I'm writing an application DAQ simple enough to use in a freshman Engineering Lab is written to the USB-6211. Since it will be used at more than one campus, I try to make a compiled application. Demand, such as built in LabVIEW 2011, works very well. The problem is that the compiled executable hangs in the same places without fail. I've included the source VI unmodified and a version with the acquisition of data code disabled and some dialogue inserted to track the progress of the request. Executables for both are also included.

    I use a architecture of producer/consumer-events to manage the three tasks of data acquisition. Consumers loop will fail after one of the three DAQ events are executed. Consumers loop works very well for the exit event. I also returned to LabVIEW 2010 and recompiled, the same failures.

    Any help is greatly appreciated!

    Stuart

    I think that if you close the front panel to start the VI, it will leave the built application.

    Replace the properies "FP.open" with "FP." State"and toggle between 'Hidden' and 'Normal'. That seems to work in my limited testing.

  • LabVIEW labview 2011 2003

    I am completely new to labview and I want to do a compression test with frame of MTS

    I got a code that is written in labview 3 but it does not work (I think it's a problem compabality) in labview 2011 (the version I have access too and my acquisition of data works with)

    I have to fix as soon as possible because I do my research and I did not have enough time to understand the code. I use PCI-MIO-16-4 and I need to 3 channels for moving loadcell, extensometer and Phillips.

    I appreciated if anyone can give me a direction for this

    Thank you

    Roozi

    Your topic says 2003 but your message says version 3 - a huge difference. If you are able to load, it is not the version 3. See if you get an error message that the code is old to convert, then post to Conversion of Version map you linked to at the top of the page.

  • Font size too small LabVIEW 2011

    Hello

    I'm new to LabVIEW 2011.  I'm running a problem when I load LabVIEW all the font size seems to be very low and I don't know how to do more.  It is difficult to see where everything is small.  Please see photo attached below.

    I tried to fix LabVIEW 2011 and I even uninstalled and reinstalled but the police still proved to be small.

    Help, please.

    Thank you so much in advance.

    Marlin12

    What operating system? Have you changed a setting in the operating system, like maybe the default font size or DPI settings? Try deleting the file labview.ini and have LabVIEW recreate from scratch (it will be repeated when you start and it can not find). You can also try adding these lines to the labview.ini file:

    appFont = "Tahoma" 13
    systemFont = "Tahoma" 13

    dialogFont = "Tahoma" 13

  • Deal with failure when using LabVIEW 2011 and DSC MODBUS communication

    I'm currently reading from operating records a PLC with MODBUS/TCP. I confirmed that the PLC will update the values and in response to a MODBUS communication correctly by using a third-party program called Modbus Poll. However, when I try to query the PLC using the LabVIEW shared variable engine, I am unable to read the values of the same addresses that I consult with Modbus Poll.

    My installation is simply to a PC directly connected to the controller via Ethernet without a router between the two. I'm using LabVIEW 2011 SP1 with the DSC module.

    I opened the Manager of distributed systems OR to display the State of all variables in the Modbus Library that I created, and I noticed that the ILO CommFail permanently the value 'true '. All other variables with a 'read' access mode signal "failure of process". I tried to restart the process and stop and start the local variable engine without success. I also restarted my computer several times to see if any services did not exist, but this does not appear to have solved the problem.

    Finally, I resorted to listening to communications on the network card I have the PLC connected via Ethernet using Wireshark and found that while Modbus Poll communicates with PLC, number of MODBUS and TCP packet is sent and received. However, when using only LabVIEW or the DSM OR communicate with the controller, there don't seem to be any communication on the network card.

    Something that may be interesting to note is that I could communicate with the PLC and to read values with the DSM just once, when I understood everything first what address I should be reading of. All of this has stopped working shortly after. Prior to this, 'CommFail' was not generally set to 'true' with my current setup. Thinking it was my firewall, I have since disabled my firewall, but this seems to have had no effect on the problem either.

    Any help on this would be appreciated.

    So, I thought about it. It turns out that the IP address of the server i/o MODBUS must be set to the address of the MODBUS slave, not the local computer. The address of the i/o MODBUS server is defined by the navigation in the Explorer window projects, expanding the variable engine shared library for MODBUS and right click on the server MODBUS (for example Modbus1) item and select Properties.

    In addition, the addresses seem to be shifted by + 1.

    Thanks for the tip so.

  • DAqmx and IMAQ pallets do not appear in my palettes of LabVIEW 2011

    Hello

    I use LabVIEW to my University via a Campus license since 2005. I installed it on several computers.

    My problem is related to a new LabVIEW installation on a brand new computer.

    I have the license Site LAbVIEW 2011 Academic just installed and validated (via the License Manager) in this new machine running 64-bit Windows Seven.

    [I also installed the DAQmx and the "distribution of February 2011" IMAQ drivers (downloaded from OR) as well as the NI Vision Software (version for LabVIEW 2011, the same distribution as the LabVIEW 2011).]

    I launched LabVIEW Ant checked to see if everything was there, specifically the DAQmx and IMAQ functions, since I have the cards OR to make the acquisition of data and images. Note that I have not yet installed these cards in the PC. I m going to do only when I would have ensured that all the software is ok.

    The subpalette DAQmx in measurement of i/o functions palette is missing.

    Also, if I'm looking for the NI-IMAQ subpalettes in the range of Vision and movement functions they also lack.

    Notice that all other subpalettes in the range of functions of Vision and movement are OK and there appear (utility of Vision, Image Processing, Machine Vision, and Vision Express).

    Then, I checked if the installed drivers are really there. For this I used the MAX or (measure explore), and it looks like it all everything is there.

    I mean, under NI MAX > my system > software I can see these articles:

    NEITHER Vision TERM 2011

    NOR-IMAQ 4.5

    NOR-DAQmx... several entries

    I checked if the forum or knowledge base in NOR have any clue on what to do, and I found somewhere by the idea of trying to fix the installation via the Windows 7 Control Panel > programs and resources > OR software.  I did this procedure twice, just in case...

    I also tried to remove and reinstall all software (including drivers) and NO, I did it twice. The result is always the same.

    Any suggestions?

    When you install the drivers, you include support for LabVIEW 2011?  If this isn't the case, you won't see the LabVIEW screw in your palettes even if the software is installed.  Normally I expect that the Setup program automatically adds this support, but he can't do it, especially if you have installed the drivers before installing LabVIEW.  See the image below:

  • LabVIEW 2011 SP1 makes such a big difference?

    Here's my work construction specification in LabVIEW 2011

    Any idea?

    First of all I spend time to upgrade to 2011SP and after the update, when I learn about broken build specification. I started to wonder is it really worth spending time to upgrade?

    BTW, the problem is resolved. How I have no idea. For the first 2 times, I opened the project, the build specification has been broken and the third time that I was correct. Fortunately I did not spare the first project 2 times.

  • Control CMD (command line interface) using Labview 2011.

    Hello

    I'm trying to control software that has an interface to command line using LabView 2011 but I have problems when reading the information.

    Is attached the VI I created so far, but it is not working properly.

    Problems so far:

    1 - if I use ReadLine(), it blocks showing no error and nothing else.

    2 - ReadToEnd () same problem as the previous line, the software hangs just at this stage.

    3 - if I compare the response of the "peek" in waiting for the - 1 indicating there is not more character, the hook of software as the previous steps.

    You have some clues as to what might be wrong or another way to 'control' the CMD to send messages, read and send messages, etc...

    Thank you very much for your help.

  • LabVIEW 2011 f2 [x 64]: no drop-down menu of "Targets" in the "Getting Started" window

    Is this normal? I don't remember if selection "Targets" was there at the start, but it isn't here now! I installed the Module, the Module 2011 WSN 2011 Vision and ARM 2011 Module and their icons appear on the startup initialization screen, although there is no ARM Module screws present in the ADE.

    If it's a bug, what should I do to fix?

    Thanks in advance,

    I guess as 64-bit LabVIEW 2011 is not compatible with these modules, they will not fill the list started with targets.  If they appear correctly in 32-bit LabVIEW 2011, it is most likely the problem.
