• Open the file using Labview 8.5 traditional NI VI

  Hello

  I want to open this VI I have attached below using the version of labview 8.5

  But when run the VI, the error message pop out as below:

  

  I suspect this VI to traditional aid OR component.

  How can I run this VI using my latest version of Labview?

  Thanks in advance

  Yes, you're right. This is the traditional DAQ VI.

  Install traditional DAQ 7.4.4 (WXP or W2000) and check that you activate LabVIEW support when configuring the installation program.

  PS: The LabVIEW 8.5 and traditional DAQ are not supported under W7. See here (OS<-->LV) and here (DAQ<-->LV).

• Can I know how to control the robot using LabVIEW? My PLC is Omron CJ1M-CPU11-ETN21.

  Hello

  I am new to LabVIEW, and I need help with the configuration between LabVIEW and the controller. My PLC is Omron CJ1M-CPU11-ETN21. I have the DSC Module and I have an OPC server as well. I create tags or even used the shared variables to try to write to the output of the PLC, but it does not work. The configuration for the ethernet Powerline had done, and I can control the PLC using CX-program via the Ethernet module. May I know what are the problems?

• How to determine the length of the string when the string using LabVIEW MoveBlock pointer dereference

  Hello!

  Calling a DLL that returns a pointer to a structure consisting of a pointer to a string, a 32-bit integer and a pointer to another string.

  I managed to MoveBlock to return a consolidation of these three things, and which works very well.

  But now I need to read the two strings I have pointers to which are not fixed length. MoveBlock has a size of entry, but how to know how long channels are?

  Try this:

  ...\vi.lib\Utility\importsl\GetValueByPointer\GetValueByPointer.XNode

  Wire just a constant string to the Type of entry.  If I remember correctly, the draw of endpoint (assuming that the C strings) will be included.

  Sometimes I have just MoveBlock a byte at a time until I get to a null value or has specified maximum size.

• stop the script with labview

  Let's say that I run a script using the "DIAdem"run script.vi"due to the demand of the user.  Later, the user wants to cancel because it took longer than expected.

  How to stop the script using labview tools?

  Jim

  Hi Jim,.

  It is possible, but not in the way I think you hope.  I don't know any way to end a VBScript script running in the DIAdem of the 'outside '.  If you have been watching DIAdem you could hit the key, but a subsequent application of LabVIEW goes in "Script stack" of DIAdem and does not run until the first VBScript happens naturally.

  Of course, you need to run all your calls of LabVIEW to Sophie in an asynchronous way, or does not.

  If you can do is set up each VBScript that you think you might want to abandon to periodically query a global variable of tiara, say "B9" and end of inside the VBScript if B9 = TRUE.  LabVIEW DIAdem (ToCommand) command interface will stack Script tiara, but variable interface of LabVIEW DIAdem (ToDataSheet) does not work.  If you can "poke" during execution of the first VBScript variable B9 of LabVIEW and influence its behavior, but only if and when this VBScript uses this variable (B9) get bitten.

  Of course, none of this helps if your VBScript is busy waiting for a simple VBScript command to run, and it helps only if your VBScript executes several activities, among which it can interrogate the variable (B9).

  Hope that helps,

• 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.

  
  

• Missing Sub VI during the opening of LabVIEW file

  When I open my main VI it is unable to find several Sub VI, but the missing Sub VI are supposed to be installed with NOR-DAQmx, that is installed. Among the missing Sub VI 'DAQmx Read', 'DAQmx Start Task', 'DAQmx stop mission' as well as a few others. I tried to open the VI using LabView 2013 and 2014 and have had the same problem with both. Any help is appreciated.

  Have you installed DAQmx after LabVIEW installation?

  You have selected LabVIEW support when installing DAQmx?

• you want to send data using labVIEW to arduino using write visa and the process and to take action using arduino. A

  I want to send data using labVIEW to arduino using write visa and the process and to take action using arduino. After that, I want to arduino to send out necessary via a serial port to labVIEW which should be read using visa read and store in a chain. While I am able to write or read both individually, I can't do it consecutively. I used advanced read and write vi for checking my code, but nothing is helping. The wrong bed 'time delay before execution. " Please let me know where I can go wrong. Also is it possible to write code for hx711 using labVIEW

  1. you need not "\n" on your orders println().  This command adds an end of line character already in the message.

  2. you get the error because you have a loop around your reading.  After the first reading (well technically, the second because of you add an extra line end character), there is nothing left in the port.  As a result, you will get the timeout.

  3. you should really consider using a Structure of the event.  This way you just don't write and read when you press the Write button and you can also use the structure of the event to make the loop to stop.  I also go up to close the port inside the stop-> value Change event.

  Hello

  If you plan to build your app for Windows, you can use .NET classes. (System.PerformanceCounter), there is a simple example with LabVIEW:

  Also, you have several screws that you can use to verify information about the processor.

• Go to the PHP website using Labview 8

  Hi people,

  I'm writing a vi LV8 to retrieve data from a Web site. The first site I've played with just had a text output so a simple:

  -OpenTCPConnection (for 'www.hpc.ncep.noaa.gov')

  -WriteTCP:

  -line 1: 'GET heat_index_MEAN/hitable_east.txt '.

  -line 2: "" Host: www.hpc.ncep.noaa.gov".

  -line 3:

  -ReadTCP

  It worked perfectly fine.

  But this isn't really the data I want. I want the data displayed on the Web site:

  http://forecast.weather.gov/MapClick.php?W0=t&W1=TD&W2=Hi&w3=sfcwind&w3u=1&W4=sky&W5=pop&W6=RH&W7=th... 96 & textField2 =-77.48167 & site = all & unit = 0 & dd = 0 & bw = 0

  But, when I try the same calls I get the error messages like:

  -If Yes, which?

  -I can access a Web site (which uses PHP) LabVIEW?

  -what I have to learn more about PHP to proceed?

  -J' tried to send a command "OPTIONS" of HTML, but I received very similar eror messages (not a quesstion)

  -the site has an XML option that displays data as text/XML, but it also seems to use PHP, if I get the same errors with my code (not an issue)

  -any ideas on how to use labview to read data from this site?

  Thank you, in advance...
