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? How do you have them/plan to have them connected to your computer? 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)? The more information you can give the better help you will receive. Cheers
It would also be helpful to know what version of LabVIEW you are using. It's impressive that your starting to learn LabVIEW at such a young age, it will be challenging but worth it!
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
It looks like your controller is designed to be programmed in BASIC. What you will need to do in order to control it with LabVIEW is figure out what the function calls are that will be required to activate your PMW signals etc.&a...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. Has anyone done something similar? 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. 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. 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. 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. Perhaps LabVIEW itself already provides for multiple serial card communications (wouldn't that be perfect)? Any info would be great. Regards, Dave
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 - built-in and USB->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 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 ...How can i use labview.tlb to control Labview from an external application?
I've been told by a labview engineer that i could use the file

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
It is not possible to 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> Or call your local NI branch office. But if you are planning to do more realtime projects 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>

...can Labview 7.0 control an instrument without the labview driver?
hellow,i have an instrument which do not have the labview driver,its
output signal is RS232,so can i use labview7.0 to read the signal?
Another possible option is to use the Instrument I/O Assistant. It is
an interactive tool that generates Instrument I/O and response parsing
code for you. It is very helpful in establishing a connection and
helping parse instrument response data. It is pretty high level and
basic, so if you want to utilize any special serial VISA functionality
it may not go as deep as you would like - but it can definitely help
get you started.
...VIs that allow you to test if a given control is a control of a particular LabVIEW class type
The attached zip file contains VIs are saved in LabVIEW 8.5.
Included in the .zip are three VIs you may find useful when working with LabVIEW classes.
- Qualified Name Array To Single String.vi takes a VI's qualified name, given as an array of strings, and converts it to a single colon-delimited string. This VI may be useful for working with VIs owned by any library type, and it is used as a subVI of the other two VIs in this .zip file.
- Is This Control Of This LabVIEW Class.vi takes a control refnum and a LabVIEW class refnum and tells whether the control is an instance of the given LabVIEW class. It returns true for regular class controls/indicators and for XControls of the class.
- Is This Control Of LabVIEW Object Class.vi is the same as the previous, except it does not take a class refnum for input. LabVIEW Object is the built-in class that is the ancestor of all other LabVIEW classes, and this VI specifically checks to see if the given control is an instance of this class.
The second two VIs in this .zip file are both password protected. In a built application, both will return a "not supported" error.

I?m having problems using RT Reboot Controller and RT Ping Controllers from the Real-Time Utilities palette with LabVIEW 7.1, but only with PXI-8184 controllers. This work fine with PXI-8175.
The attached VI will list all the 8175 on the subnet, but none of my 8184. However, I can ping and FTP all my 8184. If Local Subnet? is TRUE, I don?t get any error, but the RT controller doesn?t reboot. If it is FALSE, I get: Error 63 occurred at TCP Open Connection in FPC open connection.vi->RT Ping Controllers.vi->MssUT-RebootController.vi.

There seem to be USB drivers for that device. 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 (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.

...LabVIEW 8.0 changed a constant that was wired to a Case structure to a hidden control to maintain compatibility with LabVIEW 7.1 and earlier.
Y am i getting this msg?
This happened because "...LabVIEW does not compile code on the block diagram that does not execute. For example, LabVIEW does not compile any code that exists within the inactive subdiagrams of the Conditional Disable structure. In addition, LabVIEW does not compile code within a Case structure that has a constant wired to it that would not execute the case with the code..."In the other words, if you have case structure, which is wired to T/F constant, then prior to version 8.x both cases will be compiled. From version 8.x the only "executed" case will be compiled. So, LabVIEW replaces constant with control for ensure that both cases will be compiled as before.

Ray FarmerMessage Edited by...Control Device with Labview
I work with NRVD Power Meter and I found some drivers for Labview, the only cable I have to connect to my PC is GPIB connection
where should I search my device in Labview, a message appears when I open the drivers saying I have a mistaken programing in VISA.
I am just now reading the tutorial but I would appreciate help.
Let's start with simple steps (basics).
To find out if you can communictae with your instrument, I suggest using MAX (Measurement & Automation Explorer).
It is typically located Start>Programs>National Instruments>Measurement & Automation.
In the configuration browser, click on "Devices and Interfaces". You should see your GPIB card (device). When clicking on "Scan For Instruments", the Power Meter should be listed under it's Address. You can use the "Communicate with Instrument" to see if it responds to simple commands, like *IDN?
This would be the first step. Please note the GPIB address, as you will need it later, to communicate to it within LabView.
...Motion control with labview
I'm working on the force feedback control with labview.
Two stepper motors are controlled by force feedback of Load cells (target force input by operator).
In terms of control the system,
can I use "velocity control" to control stepper motor?
- I've tried that stepper motors have linear motion to get target force.
But, I programmed it with repeatation of move&stop motion.
Two motors check the target force from load cell after every short movement.
The problem is that the delay of signal responses caused with the contol loop.
Could you show me any idea for my force feedback control?
Hi Ycano,Yes, you can operate your motor in velocity mode by using the Set Operation Mode VI to change it from position mode to velocity.As for your control feedback loop, are you bringing in the feedback from the load cell via a separate DAQ card? If the load cell outputs a voltage in the +/- 10V range (if it's not a current transducer or doesn't require an excitation voltage), you could connect it straight to the analog input on your motion controller and directly implement it in your control loop for your motion controller. ...Labview and Xbox controller

I need to know the packet the controller or the guitar is sending to the computer.I hope that some one already have a program that can do this or maybe someone has an idea how could I achieve it. Are there any libraries for USB or any tutorials?Thanks
Look at the Input Device palette. This should enable you to read from any
input device recognized by windows.
...Labview resizing control.....
I am in the middle of developing an application that will be bundled with our product. I have developed many such applications using visual studio, however this is my first adventure using Labview.
As many of you know, one of the most common variables in distributing an application is the und-user screen resolution. With the relatively recent explosion of differing screen resolutions and aspect ratios, making applications resolution independent is even more important than ever. Along with this, giving the customer the ability to resize the appliction at will is a huge benefit. On many occasions I have walked into a customer's site to see my application shrunk down to a corner of the window, where the use can still see it, almost like an indicator.
For visual studio, I had purchased a third party control. Plunk the control onto the window (it became invisible at run time) and all of the controls, fonts, etc resized as the screen was resized. When visual studio went to .Net, this particular control no longer worked. I had to evaluate 5 different controls to get one that even came close to working properly, and even then I had to work with support and beta test many versions of that control to get the bugs out.
Now I know that Labview has the panel resize options, etc and I have played around with them. However, a...Control systems in Labview?

I think you can achieve this using LabVIEw itself.
Or try searching the forums for Control System toolkit.
Also, there is a VI in the Analyze -->> Signal Processing -->> Frequency Domain palette.
See to it if it can fit your requirement.
...control labview remotely
I am in the process of designing a home automation software program using labview. I don't know a lot about networking so I need some help. I have digital IO boards that I want to contol a relay bank to control my home equipment, that part I know how to do. Right now I can use remote desktop connection to control my VI running on another computer. What I want is to have one computer running my main program and contolling my digital IOs. I want to be able to see this VI running in real time and contol it from anywhere on any computer which should be possible. I think if I have the main computer be a server computer running server 2003 I think it has its own kind of remote desktop connection. What I don't like about using remote desktop connection is when you log into the other computer it logs that computer off. I want to be able to see what is happening in real time. So I could be standing beside the server computer running the VI and log onto it with my wireless laptop and watch live as I turn on different digital outputs. Does this seem possible? I know of a guy that was really good with PLCs and he had PLCs running his entire house with live video and everything. He could get online and control the PLC from anywhere in the world.

...LabVIEW to control a PLC
So on the NI website there is a lot of white papers talking about how
it is easy to integrate LabVIEW into an existing control system. I
have yet to see anything good examples of this though.
I am wondering if anyone out there has used LabVIEW as a build on to
an existing control system using mainstream PLCs such as GE 90-30s or
VIPA (Siemens) or AB.
Then were you able to remove out the standard ladder logic program and
use the PLC as a central control for the I/O and thus have LabVIEW do
the thinking, be it in a PC or an embedded controller.
...Stepper control with labview
Im developing a project with a lazer pointer attached to a stepper motor, my program allows me enter a value and make the stepper "step" a certain amount of times .This works ok but I have to stop the program running and start again in order to make the stepper step again.Is there a way that I can enter a value to make the motor rotate then enter another value to make it rotate again without stopping and starting the program. Ive attached my vi
any input is much appreciated:smileywink:
You could use the auto-indexing feature, to work through an array of step-indices. See the attached example.
The auto-index feature will step through all elements you put into the array-control automatically inside the for-loop.
Hope this helps!
The vi you sent me wont open..????
not sure if aoto-indexing will work because my program already allows me to control the number of steps,ive tested it my motor and its fine, the problem im having is if I get it to step say 24 times and I then want it to step 48 times I must stop the program enter the new value and start it again. I want to be able to do this without stopping and starting the program.
