• Control via RS232 interface labview DC power supply

  Hello world!

  I'm new to labview and I'm trying to control a DC power supply using a serial RS-232 (output voltage). I can't use an interface Gbspecifications TO have only a single module that is used for another task. Any advice on how to go about it in labview?

  Thank you very much!

• description interface LabVIEW node will not work when compiling

  Hello

  I have a vi that seeks VISA resources and focuses on their name of the interface to select that you connect to.

  I have a strange problem where, if I run the vi in labview it works fine. When the vi is compiled into an exe file, it does not work.

  I traced the problem to the property node "name of Inst Intf' which gives the description of the interface. In Labview, the node of this property returns the description of the interface, as expected.

  When I compile the vi, this node property returns empty strings.

  The station nearest you, that I could find to this kind of problem is it

  However, the exe is running as an administrator, so I don't think it's a problem with permissions.

  Any help would be greatly appreciated.

  I have no idea of what was the cause, but I uninstalled the device drivers for the hardware I used, reinstalled and then restarted the computer and now it works fine.

• Operator Interface labview and teststand back the call for promotion of status sequential

  Hello

  I am looking for a solution to be able to take by the API Testand 'call sequence' status key of my teststand sequence.

  The idea is to combine, on my operator labview interface a specific indicator pour each call sequence 'important '.

  Example: an indicator to test consumers, another for power supply, an another SoftComm ex but not pour tests under

  The first solution that comes to me and inspired by what I could find on this forum is the utilistion method PostUIMessageEx en post expression for each call sequence don't I want to get the result.

  I find this solution satisfactory sector a bit heavy and a little too dependent on the test sequence she herself.

  Other solutions of would they?

  Please pour your contributions

  Hello

  In general, I get the UIMessage TraceCallback. So based on the name of the step (say consolidated test for example) I can do whatever I want since LabVIEW update my GUI without having to change the TestStand sequences.

  Kind regards

• How to interface LabVIEW 64bits for cRIO

  We need LabVIEW2013/64-bit interface with a chassis cRIO (cRIO-9068). LV64bit doesn't have an interface of development for the cRIO - target cannot be imported into the project. What are our alternatives to the LV64bit interface and cRIO?

  (1) TCP/UDP,
  (2) water courses,
  (3) shared, variable
  4)...

  TCP/IP will certainly work, but are there operating at a higher level methods?

  The application of data acquisition and control at slow speed (a few s/s). LV64bit is necessary because LV32bit is not compatible with other equipment essential in our Setup: the operating system is 64-bit and the driver does not mix of application of operating system and 32-bit 64-bit support! LV32bit will be used of course for the development of cRIO.

  Tips are welcome.

  Hello heel,.

  This behavior is because the method of linking to the shared variable is not exactly the same.  The two cases are the following:

  (A) your "Block diagram" shared variables.  You use (Interactive) project-style shared variables that are just that-variables implicitly this VI through the project.  The host variable must be a valid target in the project to allow you to use this method.  This interactive method is somewhat simpler, but it has limits (have you meet).

  (B) binding to a front Terminal.  It is actually using the API of programmatic OR-PSP connection behind the scenes and uses a network path to the variable library rather than a link through the project.

  This is a little better detailed in the help topic for LabVIEW here:

  LabVIEW Help: Using Variables of e/s (time real, Windows)

  http://zone.NI.com/reference/en-XX/help/371361K-01/lvioscanhelp/io_vars/

  See the "IO Configuration Variables" Section of the document linked above, which details the differences between the two approaches a little better. You can certainly link to a shared container hosted RIO of LabVIEW to 64-bit, you'll just have to do so explicitly using the API of the PSP.  More information on the use of these functions can be found here:

  LabVIEW Help: Reading and writing of Variables shared by program

• Code error undefined-2147352567 interface LabView with a Baldor Flex + Drive II

  Undefined error code '-2147352567 occurred at the unknown "are not in documentation of Baldor or LabView.

  Error seems to happen when the ActiveX methods that the entries of evil, but to the best of my knowledge, they have.

  Has decided that it is possible that the axis has not been activated for all/check activate State I used a method of DriveEnable, it worked (code provided "Baldor test.vi"), the VI active / disable the drive correctly.  Documentation for Baldor does not seem to mention any other measure, you need to take apart from activation before using the movement commands.  Placing the jog command after that DriveEnable causes the error to return to the command of Jog (Baldor test2.vi ' ").  I'm trying to find out what is the cause of the problem, using MoveA, the MoveR, DoGo methods instead of Jog all produce the same error.

  Same error to the method DriveEnable when I try to run the code on a computer that the player is not currently attached to, leading me to believe it is a mistake of communication rather than a material error, as this is the first point at which the program tries to communicate with the hardware.  The player also appears fully functional, no errors in the Workbench of Baldor v5, orders work very well in this environment and controller to update to the latest firmware.

  Solved, still don't know what the error message is but I worked around it.

• 1766 BWAA PLC - interface Labview Act really strange

  Hi all

  It is a very, very odd response, I want to come.

  I have an automaton of 1766-BWAA with which I am in communication via modbus.

  an AIN, a DOUT and a DIN module is connected to the controller.

  When I decide to the PLC using Modscan - coil status, entry status, registry entry - I am able to control the robot. Can I read/write of the coils, read AIN read module DIN modules. This is why I think that the problem might be with Labview.

  but when I try to do the same thing with Labview, I get only the part right DOUT. AIN and DIN give me the strange answer. Here's the situation.

  AIN module: I connected a source meter in AIN. I give the source alternately to channels 0-4. but the labview program reads the registry PLC only if I read once by using modscan. The sequence for detection of AIN in Labview is (!), concern 1V AIN0, run modscan, labview. apply 2v to AIN0, run modscan, launch labview. The current value and the previous value now appears in the labview alternately. the duration of this fluctuation is 5. (reading that I will be AINvalue to 1V, value AIN to 2V, junk, junk, junk and this cycle repeats. strangely, its iterations always 5)

  Same situation with DIN. If I want the value in Labview, I read in modscan once. Its like he labview follows modscan.

  It's weird. I am not able to understand why thi happening. VI that I used for the reading of the PLC is attached.

  Any help will be appreciated.

• How can I join buttons visible teststand keyboard shortcuts in a labview user interface

  On a normal labview VI, it is possible to configure the desired for example key navigation options assign a keyboard shortcut to a control. Is it possible somehow to assign a keyboard shortcut to the visible controls ActiveX Teststand i.eg. a basic custom user interface labview Teststand button?

  Help, please

  You may be able to do by cloning of each button, assign a shortcut to the clone, and then firing an event and call the method "DoClick' of the TestStand button - I say maybe because I can't verify the DoClick method will do what you want.

  Obviously, you can hide the clones on the front panel if necessary.

  

• The interface of LabVIEW and matlab

  Hello, I want to interface LabVIEW with MATLAB using the TCP/IP protocol for data transfer. Can anyone, please give me an instruction step by step how to do this? If not, can point out you where I can get them? Thank you.

  Hi Gilles,.

  TCP/IP is a generic protocol then you should easily be able to build enough interfaces TCP/IP for your LabVIEW and Matlab code and data transfer on ASCII or variants, etc., depending on what kind of data you are trying to transfer. I'm not too familiar with Matlab, but on the end of LabVIEW, there are a few examples of server and client very good TCP/IP provided with LabVIEW.

  Another option you may want to, and the reason why I answer it is that I did recently a project through which we took some legacy code MATLAB which we wanted to transpose into LabVIEW, so that we can automate then completely a test system that we use TestStand. A big part of it, we have been able to derive equivalent LabVIEW, but some functions where LabVIEW does not have an equivalent appropriate, or where it was simply more effective, simply copy us and paste Matlab code in any event in the first instance MathScript nodes (not dependant on Matlab) or Matlab script nodes (which will return if all goes well at a later date to transpose in full) LabVIEW for that is no longer dependent on a Matlab license).

  In both cases, the facility to do this was very impressive, and we were able to wrap huge amounts of code Matlab LabVIEW with very few problems. As an idea, have you considered your functionality of Matlab of packaging in this way and keeping all the customer TCP/IP and comms server in LabVIEW?

  Note: If you have not found it pick up the palette "Matlab Script.

  Good luck

• interfacing of labview with relays

  Hello

  Could someone please tell me how could interface labview in a relay at the hardware level external to the switch of a circuit path. Thanks in advance...

  Concerning

  GPIB isn't DAQ hardware. If you have a GPIB instrument that has a kind of switch, you should mention that first place and if you want to help in the control of this instrument, provide the brand and model. I also hope that you have already checked for an instrument to aid driver > find the instrument Drivers.

• Alert about the NOOB - interface DIY to labview circuit suggestions?

  Good afternoon everyone,

  Long story short, I did not use labview in years and years and years.  I wrote code built-in to most and c# and the design material since my days of recording data.  As fate would have, I just become used by a very very large company that seems to have a love with Labview interest, so I will use to automate some tests and other whatnot.  For everything that I have, it is clear how to go.  I'm more concerned about how I could make interface labview for personalized, switches, relay, simple stuff like that stuff.  Maybe just control and not proofreading.

  So my question is, is there, and if so, what is it, a circuit interface that would allow me to plug and interface to a piece of custom circuitry.  I'm guessing a series or USB or maybe even an interface chip FTDI or something would seem logical.  I can do everthing beyond that, I don't want to go down rabbit hole if there is a proven simple circuit already out there.  I know there are few interfaces (myDaq?), you can buy, but I'm hoping to find a way that I can't buy anything and I can just incorporate some little project that I do.

  I googled around and have yet to find anything.  A general topology is good, a schema is better, a diagram with code source (if necessary) is ideal.

  So what you know?  and thanks in advance.

  What is and Arduino? They are cheap and once you have something doesn't work, you can load the bootstrapper Arduino Atmel virgins and incorperate into your design.

  It is predefined code LabView as cominucates with an Arduino and use it as a simple Board DAQ/DIO. That is, it must always be teathered it do not program the Arduino to run stand alone.

• How to interface a sensor with IO-Link

  Does anyone have experience interface LabView with IO-Link? I have a remote sensor that can be apparently programmed using IO-Link, but information on the IO-Link bus is rather sparse. I would be very happy if someone could share their experience/advice.

  Hi Dan,.

  Sorry, we do not have a simpler solution. I would like to know if you find a way to go on this.
