Trying to generate two analog voltages to control two mass flow controllers simultaneously using a USB-6009 multifunction I/O module
Hello all.  I'm trying to create a VERY simple vi to allow me to control to mass flow controllers simultaneously, with the two 0-5Vdc analog outputs found on the USB-6009.  I've tested the device under "devices and interfaces", and I've set up two NI-DAQmx tasks under Data Neighborhood.  Whenever I try to run the vi, I get the following error:   Error-200371 occurred at DAQmx Create Channel (AO-Voltage-Basic).vi   Possible reason(s):   Requested multiple virtual channels that correspond to the same physi...

How can i use labview.tlb to control Labview from an external application?
Hi, I've been told by a labview engineer that i could use the file labview.tlb located in the labview install folder to control labview from an external application (in my case, a C# app). I'm using Labview 6.1 under Windows 2000. This article confirms that: "ActiveX and LabVIEW" http://zone.ni.com/devzone/conceptd.nsf/webmain/5401BE584FBAEECE862567C2006D36C7?opendocument But i've not been able to find out how to use this file to achieve what i want. I just want to be able to open/close labview, open/close a vi, start/stop a vi, hide/show a vi from a C# application. Th...

How do I use a LabView control element as ActiveX Control in another application?
I am was trying to include some simple ActiveX Controls(sliders, buttons) in my VBScript. It worked with other ActiveX Components from the web, however I wasn't able to include the LabView ActiveX Controls because I was missing the necessary IDs. Moreover I was able to test the LabView control by inserting it into the VC++- Test Container. But I still can't find the necessary IDs... I don't believe that any of the LabVIEW controls (except for 3D Graphs) are ActiveX controls so I'm not sure what control you were able to insert into the VC++ container. What's the exact name ...

Using the cFP controller with only LabVIEW and FIELDPOINT software but no LabVIEW RT
I have a cFP-2020 controller and cPF-AI-100 modules which I intend to use in a small project. I do have LabVIEW and FIELDPOINT software but I dont have LabWIEW RT software. Is it possible to use the cPF controller with only just LabVIEW? if yes, I would like to be advised how. Thanks Dear Chuma, It is not possible to&nbsp;set up your system without Labview realtime module. There are system integrators who can build a executable for you. You can search for a alliance member by using the following link; <a href="http://sine.ni.com/apps/utf8/niaa.search_display" target="_blank">http://sine.ni.com/apps/utf8/niaa.search_display</a>&nbsp;Or call your local NI branch office. But if you are planning to do more realtime projects&nbsp;in the future this wouldn't be costs effective. Another option is to use compact fieldpoint pc controlled backplane (so there has to be a PC to control your compact fieldpoint system (not deterministic)). You can do this by using the compact fieldpoint ethernet backplane; <a href="http://sine.ni.com/nips/cds/view/p/lang/en/nid/202527" target="_blank">http://sine.ni.com/nips/cds/view/p/lang/en/nid/202527</a>&nbsp; Good luck with your project, and please let me know if there are any questions, &nbsp; Martijn ...

Have you installed them? Was there a DLL provided? If so, you can call the DLL functions using Call Library Function. Do they have a software programming manual? Thank you for instant reply. I downloaded the driver. Its not helping to run it using labVIEW. They do not provide DLL. They provide some VI. Its not helping much. Thank you. Well, I don't have the instrument or the drivers so can you provide some details into this VI that they provided? Perhaps if you upload it&nbsp; (assuming the license agreement for the software allows you to do so). Thank you. just few minutes ago I could make the motor run using the VI they have provided. ...

mass flow controller

How to easily control multiple controls in labview
How can I easily control multiple controls with a single write to in Labview? For instance, I need to update 50 different boolean indicators. When I update them one at a time I use a cntrl refrence in my event structure, but outside of an event structure how can I easily cycle through them and update without making 50 local variables if I need to do them all at once? Why don't you use an array of boolean indicators? Have a look at the example attached <a href="http://forums.ni.com/ni/board/message?board.id=170&amp;view=by_date_ascending&amp;message.id=204328#M204328" target="_blank">here</a>, which can also be applied to this. You should usually avoid updating the value of a control from more than one place, though (unless it's something like initialization, where you can guarantee not having race conditions). Other alternatives: using an array of booleans or using the picture control to create the image. The way i use these booleans in my UI, I had to make them separate so I could arrange them in a user friendly way. And yes this is just for initialization so they won't be getting updated in two places at once. ...

How do you control seperate motors with Labview through a remote control?
Forgive me if I am not typing the question correctly, or if it is a stupid question. I am only fourteen and only started learning about Labview.. I would appreciate all help possible. Thanks What type of motors are you trying to control?&nbsp; How do you have them/plan to have them connected to your computer?&nbsp; When you say you want to control remotely, do you mean that you don't want them connected to a computer or that you want to communicate remotely through your computer (no cables)?&nbsp; The more information you can give the better help you will receive. Cheers Hi LouidSilence, It would also be helpful to know what version of LabVIEW you are using.&nbsp; It's impressive that your starting to learn LabVIEW at such a young age, it will be challenging but worth it!&nbsp; Well first off, thanks for asking questions to my questions, it helps me too :) The kind of motors I am trying to control are IFI Robotics Multi-Speed Motor Connect to PWM or RLY port (12 volt).. I am trying to remotely control it wirelessly, through an IFI Robotics Isaac16 EDU Robot Controller with 900MHz Short Range Radio Modem. Hope this Helps.. Oh yeah, and the version of LabView I am using is 8.5 Hi LoudSilence, It looks like your controller is designed to be&nbsp;programmed in BASIC.&nbsp; What you will need to do in order to control it with LabVIEW is figure out what the function calls&nbsp;are that will be required to activate your PMW signals etc.&a...

How does labVIEW use ActiveX controls?
How does labVIEW use activeX controls? I recently wrote an activeX control in VB and noticed that it would not work if the control was set so that its properties could not be set in ambient mode. This may suggest that labVIEW uses some activeX controls only in ambient mode. Is this the case or are there more complexities? Dan, Which version of LabVIEW do you have? As per the KnowledgeBase bellow, in versions of LabVIEW prior to 5.1 you would get errors accessing the ambient properties. <a href=3D" http://digital.ni.com/public.nsf/websearch/EE909D817E25CDFE8625666C00507D8B= ?OpenDo...

Reading controller data into LabVIEW through serial connections to controllers?
I'd like to read data from environmental chamber controllers (System Plus) into LabVIEW through RS232 connections.&nbsp; Has anyone done something similar? &nbsp;I see interfacing with the serial controllers as the biggest obstacle and although not directly related to LabVIEW programming, I'm hoping someone here can give me some advice or resources on how best to do so now days. &nbsp;My first thought is to write a program with VB or C++ to act as a terminal and write the data to a text file for LabVIEW to poll.&nbsp; Aside from using Telix decades ago to work with BBSes, my only other serial experience consists of interfacing with a Kiethly multimeter using a C++ program.&nbsp; &nbsp;I would rather not use multiple PCs but I have never worked with more than one serial port on a computer before in the past.&nbsp; Perhaps LabVIEW itself already provides for multiple serial card communications (wouldn't that be perfect)? &nbsp;Any info would be great. &nbsp;Regards, &nbsp;Dave&nbsp;&nbsp; LabVIEW has had support for serial communication for as long as I've used it and may have been part of version 1. It also supports multiple serial ports&nbsp;- built-in and USB-&gt;RS232. There are even a couple of shipping examples. I've not used this particular chamber but I've used several with serial connections. It's a matter of getting the programming manual and working through it if a driver does not al...

How do I use a xbox360 controller in labview 7?
So I've just been given a project in my research lab..&nbsp;We have to control a gantry arm using labview.&nbsp; The gantry control is already completely written out in labview using a datasocket server.&nbsp; However, I've never worked with Labview before.&nbsp; All I know is that it takes in a number as a velocity and it moves the arm according to that velocity.&nbsp; What I have to do is use the xbox 360 controller to input that number (a velocity), as well as calibrate it.&nbsp; If possible, using the mangitude of the joystick angle to input a different velocity.&nbsp;How would I go about doing this?&nbsp; I hav einstalled all the necessary software to talk to the controller, but I don't know how to set it up in Labview. &nbsp;Also, Windows XP sees it as a game controller, if that makes any difference.

i want to use labview controls in VB ? how do i do it
i want to use labview controls in VB ? how do i do it? The easiest way to do this is to create a LabVIEW DLL and call it from vb. So write a vi in labview with the front panel you want and then compile it into a dll. The only problem with this is that when vb calls the dll nothing else can happen in vb. Hope this helps. Individual LabVIEW controls are not ActiveX controls so they can't be used in VB. You can call a LabVIEW program from VB but I don't think that's what you want.

Use .NET propertyGrid control in LabView
I would like to use the .NET PropertyGrid control in my LabView (8.5) application. To populate this control, I need a .NET Object and the PropertyGrid displays the property of this object. The problem is how to create a .NET object from LabView? For example, I would like to convert a cluster of data or a LabView object into a .NET Object to display the data in the PropertyGrid. Thanks for your help. &nbsp; Pierre Cottin Researcher INO Have you tried the <a href="http://zone.ni.com/reference/en-XX/help/371361D-01/lvcomm/to_object/" target="_blank">To .NET Object</a> function? Yes but this vi is limited to the conversion of string, path, number, arrays. The .Net object required to populate this control is more sophisticated: it has members (name and value to display) and attributes to control how information is organized (section names,...). Pierre Cottin You probably want to start with a .NET Constructor for your .NET object data type and use its properties and methods to fill in its data. Then, once it's populated correctly, feed its reference into the propertyGrid control.<img src="http://forums.ni.com/attachments/ni/170/344945/1/hastable.PNG"> Message Edited by Jarrod S. on 07-29-2008 04:46 PM hastable.PNG: http://forums.ni.com/attachments/ni/170/344945/1/hastable.PNG Why not just use the constructor for your class?

If you were using "raw" pppd, you could pass "nocrtscts" and/or "nocdtrcts" to pppd. See the man page for details. Perhaps the RH dialer will let you do that somehow.
