• Strange behavior when using Labview to collect data from Tektronix oscilloscope tds8200

  I hit a wall in trying to understand this one. The problem I have is that my application will not start the oscilloscope when it should.

  I use an oscilloscope Tektronix TDS8200. My goal is to collect data from the oscilloscope using Labview waveform. First of all, my program initializes and configures the oscilloscope; This part of the program works very well.

  The second part of the program begins the acquisition of data with the function 'Tktds8k Start or Stop Aquisitions.vi', which is to press the button run on the scope. The function "tktds8k to Waveform.vi" is used and should ideally return data, which I connected to a waveform playback graph.

  When I run my program, the first part runs without a problem, but as soon as the program comes to the service get the waveform, the run button in the scope, which is green when running, turns off; the program then expires, and no data is collected.

  Here is where it gets weird. I went through the debugging to try to understand this point, and I put breakpoints on the beginning and get shape wave functions so that I could scroll through the last part of the program. The program continues with the departure function, and the button run in scope is green. The breakpoint for the function get the waveform is reached and when I press on continue, turns the Run button and turns it off then back on almost immediately. data are collected, the waveform graph appears and the program ends without error.

  I thought that the timetable could be the problem, so I did the program wait as long as five seconds between the functions of start and get the waveform and that did not work. I also tried to move the start function to before the configuration functions and remove start completely; no method worked.

  is there any ideas on why, the program works when I enabled breakpoints and isn't when breakpoints are disabled? I'm sure there is an easy solution, but I was not able to find a solution.

  I have attached a pdf that contains information about the functions of the Oscilloscope (tktds8k.pdf), and I have also attached my program.

  
  

• Strange behavior when using units and controls the ring

  Hello

  Something unexpected occurs when you use a control of the ring with units:

  1. Create the control of the ring,
  2. change the representation of double
  3. display unit label,
  4. the value of mV as a unit,
  5. edit items
     1. disable the sequential values,
     2. Add an element with a value other than zero for example 123,
     3. Ok
  6. Select the value created,
  7. create a KPI DBL with V as unit,
  8. wire from the control to the indicator,
  9. run

  What I see in the indicator is 123 V instead of the expected 0,123 V

  You guys are able to reproduce this?

  Noticed on LabVIEW 2013 and 2014, 32 and 64 bit on Windows 7 and 8.1

  Thank you

  Boris

  Bring up the digital display of the command of the ring.  You will see the units you enter under edit items menu is indeed volts.  Any prefix to units only acts on the screen.

• Strange behavior when using groupspec in netstreams.

  I started using the groupSpecifier to connect two players in a game I'm developing. Before, I was using a server to swap their farID, now I use the groupSpec netGroup, and it works well... but I got this weird problem:

  The first seconds of 2 to 8 netStream.sends command, I got like 2 seconds delay, after that, communication is almost instantaneous.

  Don't know why this is happening, but I don't want to fully implement netGroup if I'm having this kind weird behaviors...

  All do not know why this might be happening?, when I used NetStream.DIRECT_CONNECTIONS it didn't happen.

  Thank you.

  Update: looks like it's not about how long I have to wait for it to start working properly, it's how sends commands I do (between 0 and 10, seems completely random).

  the delay you see is the delay "pull" mode, while the Group relies (trivial) latency minimum spanning tree for the multicast stream ' push' mode.  probes need push mode any quantity rate data as well as the time to move from the probes to be judged.

  multicast starts at nearly 36: 25, but I recommend watching all this.

  If your groups are going to be quite small (not more than about 10-14 members) and you send data, you will find netGroup.sendToAllNeighbors () will always be a low latency, but the sender will send data to all peers (other peers don't help each other) and it will not get to everyone once the group becomes greater than 14 members.  For more information about this, which

• Strange glitch Visual on the taskbar when using Firefox

  Hello

  I feel a strange glitch Visual on the taskbar when using firefox.

  Please take a look at this short video because it shows the problem, it's almost impossible to show in pictures.

  https://DL.dropboxusercontent.com/u/12595174/VIDEO0016.3gp

  I use firefox on Windows 7 Pro 64 bit v36.0.1. Video card is an ASUS R9 280 X using the latest drivers from AMD 14.12 Catalyst Omega Software.

  Motherboard is an ASUS M5A88 with 16 GB of ram and a processor of 6300 FX.

  It is a new construction that I have implemented in the last 24 hours, and this behavior was not present on the system using the same version of windows, firefox and even map chart and drivers. But on another card mother and CPU. Previous Board of Directors has been
  M4A79XTD EVO with a Phenom II X 4 955BE.

  The glitching does not occur when it is on the desktop and firefox is closed. It will not occur when you use IE - 64 nor does it when I am using the steam software or any Explorer windows/opening files.

  All the motherboard drivers are installed correctly, the integrated graphics card is disabled in the BIOS. I disabled the settings of firefox for hardware acceleration, smooth scrolling and text... to see if it was the question. It wasn't.

  I'd appreciate any help to solve this... Really, I don't want to use a different browser but it's bad enough and quite distracting to really annoy me, and I don't see any alternative.

  Thank you very much.

  Hi jscher2000

  I was about to post a reply, because a friend suggested that maybe that's a rendering of issue rather than a firefox one video card even if it's strange how it affected firefox only. I didn't have a chance to test it on Chrome as it is a new construction and I don't want to install the software, I do not use.

  I went to the Manager of catalyst and had a glance to the settings. I changed something, but no help... I then started to make a simple change and test until I found that the activation "gpu up-scaling" in the properties of digital flat screens has solved the problem.

  I am now free twinkle

• Query Sub behavior strange when using Expressions regular Oracle

  I met a strange "inconsistent" when you use an Expression regular Oracle with subqueries in SQL. Here are some details on how to reproduce what I have observed. We managed to find a solution to this "problem" using a database index; I'm writing this case hoping to better understand why Regular Expressions Oracle do not seem to work in the same way that the older, standard functions integrated as INSTR, SUBSTR, AS, etc..
  
  Environment settings:
  This test has been done using Oracle XE (GR 11, 2) on 32-bit Windows operating system. For my test, I used the HR schema (which is delivered pre-completed with the installation of this product) with some modifications of my own.
  
  Make the Test objects:
  

  create table hr.emp_test as
  select to_char(employee_id) as emp_id_char, employee_id as emp_id,
  first_name, last_name, hire_date
  from hr.employees;

  To illustrate my test, I inserted mixed alphanumeric values and a null value in the column of my emp_id_char for good measure:
  

  insert into hr.emp_test (emp_id_char, first_name, last_name, hire_date)
  values ('XKCD123','TEST','LASTNAME',sysdate);
  insert into hr.emp_test (emp_id_char, first_name, last_name, hire_date)
  values (null,'TEST1','LASTNAME2',sysdate);
  commit;

  select * from sub2
  where emp_id between 100 and 110
  
  ERROR:
  ORA-00904: "REG_X": invalid identifier

  Our Solution...
  Add a hint to the query of sup that 'hiding' the result of sub1 in memory. That did the trick. This suspicion resembles only viable workaround for this behavior. Other old built-in functions (INSTR, AS, etc.) an they were automatically following the execution plan (results of cache memory) that he had to use a 'hint' to force with the function of the regular expression.
  
  The conclusion, which is what I would like to help to understand or explain is that:
  If you create a series of queries/sup queries or inline views, values depend on "regular expression" type built-in sql functions do not seem to stick or maintain when implemented in complex query logic.
  
  Any idea is appreciated!
  Thank you!

  This is the expected behavior and has nothing to do with regular expressions - much less directly (I'll explain later). Main rule: there is no WHERE clause predicate order. Even if you use views, views online, subquery factoring, optimizer etc. can extend your display, display online, a subquery factoring. And it's Optimizer who decides the order of execution predicate unless you use the ORDERED_PREDICATES key. Now, I can explain. Regular expressions are powerful enough but also everywhere in life to pay for it with the higher cost of execution. That's why optimizer decides to apply emp_id between 100 and 110 first and regexp_instr (emp_id_char, "[^ [: digit:]]'") = 0 later.

  Vista and Windows 7 updated drivers love then here's how update the most important.

  This is my generic how updates of appropriate driver:

  This utility, it is easy see which versions are loaded:

  -Free - DriverView utility displays the list of all device drivers currently loaded on your system.
  For each driver in the list, additional useful information is displayed: load address of the driver,
  Description, version, product name, company that created the driver and more.
  http://www.NirSoft.NET/utils/DriverView.html

  For drivers, visit manufacturer of emergency system and of the manufacturer of the device that are the most common.
  Control Panel - device - Graphics Manager - note the brand and complete model
  your video card - double - tab of the driver - write version information. Now, click on update
  Driver (this can do nothing as MS is far behind the certification of drivers) - then right-click.
  Uninstall - REBOOT it will refresh the driver stack.

  Repeat this for network - card (NIC), Wifi network, sound, mouse, and keyboard if 3rd party
  with their own software and drivers and all other main drivers that you have.

  Now in the system manufacturer (Dell, HP, Toshiba as examples) site (in a restaurant), peripheral
  Site of the manufacturer (Realtek, Intel, Nvidia, ATI, for example) and get their latest versions. (Look for
  BIOS, Chipset and software updates on the site of the manufacturer of the system here.)

  Download - SAVE - go to where you put them - right click - RUN AD ADMIN - REBOOT after
  each installation.

  Always check in the Device Manager - drivers tab to be sure the version you actually install
  presents itself. This is because some restore drivers before the most recent is installed (sound card drivers
  in particular that) so to install a driver - reboot - check that it is installed and repeat as
  necessary.

  Repeat to the manufacturers - BTW in the DO NOT RUN THEIR SCANNER device - check
  manually by model.

  Look at the sites of the manufacturer for drivers - and the manufacturer of the device manually.

• 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.

• Conversion of a project to use a library project

  Hello.

  I'm trying to convert a large main VI with a lot of sub - VI to a project that would use rather a project library. In particular, I want to pack all or nearly all my SubVIs in a library project (so that I can later reuse these subVIs to various projects) and the main VI would use this library. I hope I have the idea of libraries in the project correctly.

  Now, I thought I'll Pack all my subVIs in a library project and save it as ProjectLib, so I'll create a new project with my main VI and add ProjectLib to this project.

  Here is my ProjectLib with virtual for subVIs folders and Utils (Utils are just more generic subVIs)

  

  and here is my main project VI, with the library of projects above added:

  

  Now, I'm sure I'm doing this wrong, but I can't know what would be the right way to go about this, despite reading and re-reading helps LabView to articles on the issue (like this: http://zone.ni.com/reference/en-XX/help/371361J-01/lvconcepts/project_libraries/). Nowhere can I find a guide step by step conversion my VI existing with a lot of subVIs to this structure.

  For example, when I opened my main VI now, I see errors caused by all the missing of subVIs. My thought is that I now say my main VI: ' look, this is a ProjectLib I have included, see? Take this Subvi from there! "but I don't see an option for this.

  I would be grateful any ellucidation on how do properly what I'm trying to do. I apologize in advance for any stubbornness on my part.

  Thanks in advance.

  Hello SenSLabs,

  It seems that you are attempting to add a project (lvproj) to another project, rather than building a library (lvlib or lvlibp) and adding that the new project.  The easiest way to build a standard .lvlib is described here:

  LabVIEW Help: Creating a library to a project folder project

  http://zone.NI.com/reference/en-XX/help/371361J-01/lvhowto/convert_fold_lib/

  Once you have built the lvlib (from the old project), add this library in your project (new) and you should be good to go.

  Kind regards

• Trouble when using the FPGA to record data on PDM

  Hello world

  I encounter something strange with the use of FPGAS to save data to the disk. I use 4 channels and allows saving data PDM. I use 4 different graphs to observe each channel and no bad thing. But when I check the data stored in PDM, they are not saved in the order that they are supposed to be. Each column in the PDM should represent 1 signla of a channel, but the result shows that the data seems to fill a single column, then another. I do not understand how it becomes like this. I have attached a few photos for your information.

  The data of the FIFO.read must be 1 d table, right? So when it passes through the form 'table' in my VI, it should become a 2D of the 4 column table. Each column represents the data for each channel. I don't see any problem with this Vi. Why PDM data are not saved in the right direction?

  Thank you

  In my opinion, that you simply return your dimension sizes.  The number of rows should be 500 and your number of columns must be 4.
