How to control a NI USB 6210 from a Lab View program?

Hi,
I started today with Lab View with some earlier experience long ago.
While it took me only about half an hour to get my first program running (great), installation time nor included (of course), I meanwhile read documents for some hours and cannot find out how to control measurement hardware in Lab View.
I want to use a USB 6210 to set a 1-bit digital port. But at the moment there is no USB6210 available so I wanted to write (or do you say draw ?) the program without it and if possible simulate the hardware.
I drew DAQ Assistant into my block diagram and selected digital line output but get "No supported devices found". I don't know if the appropriate driver was installed during Lab View installation.
Also I don't understand the mechanism between DAQmx, tasks and the real hardware. Now I have a "Digital Bool 1Line 1Point" Control in my block diagram. How do signals get from program flow to hardware pin? How can I create a simulation for not connected hardware?
Any help is greatly welcome
Thanks a lot
Martin

Okay here is some more tutorials if you get some free time, specifically the hardware stuff will be relavent.

Launch MAX, it was known as Measurement and Automation Explorer, there should be a shortcut in your start menu / desktop. Under devices and interfaces you can find your hardware and open test panels to control it. This is the first place to ensure your hardware is working. If the device isn't seen you'll need to install the drivers and DAQmx software. If it is there, great.
Now launch LabVIEW. The easiest way to control hardware is using the DAQ Assistant. It has many limitations and isn't recommended for large applications. But for something quick and dirty it works fine. You'll find it under the Measurement I/O >> NI DAQmx palette on the block diagram. If it isn't there you may need to reinstall the DAQmx drivers. This can happen if you installed DAQmx before LabVIEW.
Also you'll find under Help >> Find Examples on the toolbar, many examples on controlling hardware. Feel free to post some code if you are having problems.

How to get bode plot in lab view

Hi all,
I'm just starting with lab view.
We have NI PXI system.
I need frequency responce of a servo motor i.e. bode plot,
I'm using labview 8 ,we have PXI 7352 motion controller.
I'm very confused as where to start and what is the in put to the motor.
can any one help me?

Hello,
I'm not so sure that using a motion control card is the way to go about finding the frequency response of a servo motor. In order to do this, you would give the motor a varying sinusoidal voltage and then measure the voltage output of a velocity sensor. Here is a link to a document that goes through the process: ftp://ftp.ni.com/pub/devzone/epd/lab5_frequency_response.pdf

What you want to do is plot the Log(10) of the frequency on a linear axis!!!!!!! The export - exports the values not the axis scale. exporting a log(10) of the Y axis will export the log of the axis- (of couse, you could change the graph axis scale in Excel too...... but)

I nead help in finding Lab View drivers for some instruments

Hi to you all
I am looking for some drivers for some instruments ( the list is add ), i have trayed to look for them in the NI site ( Search Instrument Driver Network - http://sine.ni.com/apps/we/niid_web_display.drv_search ) but with no luck - the specific instruments drivers were not there.
I trayed to look for the same instrument series but again with no luck
I tryed to look for the Lab View drivers at the HP site and Agilent site but the drivers that thay have are not ! Lab View drivers but self developed drivers for the instrument.
If someone maybe has one or more of those drivers, if someone know of a site that i can find one or more of this Lab View drivers or any help at all in finding this Lab View drivers will help me a lot
thank you all in advance

I agree that Christian is sending you in the right direction. I think you should be able to find about 75% of the instruments that you listed. Some you will not find and will have to develop the drivers yourself. There is a wizard in LabVIEW 8.X to help you with that.
I know from experience that several of the instruments that you listed do have drivers, so keep trying.
Hope that this helps,

How to configure a shell and tube heat exchanger with Lab VIew to get data

HiI
In our undergraduate chemical engineering labboratory we want to configure our shell and tube heat exchanger with a DAq and Lab VIEW to get information about the temperaure (of the cold fluid stream being heated), the pressure (of the steam on the shell side of the heat exchanger) and the flowrate (of the water being heated).
Can anyone suggest thermocouples, pressure transducers and flowmeters to fit between the heat exchanger and the DAq?
P.S. the heat exchanger is already fitted with thermometers, a pressure gauge and a rotameter but we don't know how to connect these hardware to the DAq

It sounds like you have enough information to pick out appropriate sensors, you just need to do the research. I would start looking through the Omega catalog, or give them a call - they're usually helpful. I can't take the time to spec out parts for you - that would be a lot of time spent on someone else's project. Most pressure sensors put out either a 4-20mA or 0-5V signal, either of which you can read through an analog input on a DAQ; measuring a 4-20mA signal requires a resistor to convert to voltage. Most of the NI DAQ boards can read a thermocouple on an analog input, but make sure that your hardware does support reading thermocouples. For accurate readings, use a device that has built-in cold junction compensation - for example, the SCB-68 connector block - and for the most accurate readings, get a board specifically designed for temperature measurement.
For the flow measurement, a standard, simple solution is an orifice plate. You put a differential pressure transducer across it, look up the appropriate equations, and use them to calculate the flow rate given the density of the fluid (which you'll be able to calculate from the pressure and temperature, since steam tables are widely available). There are other differential pressure devices available as well - at a previous job we used a V-Cone from McCrometer. If you call them they'll spec one for you - but get an approximate cost first to make sure it's within your budget.

How to get lab view to display my plot in DB

hi guys
i desigED n an operational amplifier to determine the gain product band width using a 741 chip and the gain of the circuit is 1000, meaning that the gain bandwidth PRODUCT will occur at a frequency of 100hz. but i have a problem, when i start the frequency sweep from the function generator from 10 hz to 100Khz which IS the final frequency value i have set for the program. when the lab view program stops and i export the data to excel sheet i will be getting the DB axis value in a SMALL VALUES AND IN DIFFERENT UNITES WHEN I PLOT THE GRAPH USING EXCEL, while the frequency is in log10.
pls can any one tell me how to solve this problem to start getting the right cut off frquency on the graph. find aattched my vi and the excel data from the vi that is in a different unit not in DB

Communication between Lab view and Controller via USB

USB communication between C8051F320 and Lab View. I try doing methods given in the NI site(http://zone.ni.com/devzone/cda/tut/p/id/4478) and atlast, it gives me error −1073807302 so if any one can answer my question please do post me the details concerned to it.

My devices show up as NI-VISA USB but I'm not sure if that makes a difference and I'm not using USB RAW either. One thing that you can run is a VISA Property node like below and see what it reports. Also, what version of VISA are you using? If you are not using 4.0, you can download it from http://digital.ni.com/softlib.nsf/webcategories/85256410006C055586256BBB002C0E91?opendocument&node=1....

I have a problem with running an EXE file on win2000, the Lab View is 5.1 and I do not know if it is 16 bit...what should I do?

Hi Arika,
The drivers that you need to install to make your executable work depends on what your executable is doing. To get started, you need to have the LabVIEW Run-Time Engine installed on your target machine (the Win2000 machine you are planning to use) in order to run your executable. Next, you need to determine what drivers your executable uses, if any. For example, if you are using GPIB instrument control, you will need to install the NI-488 drivers on your target machine. If you are performing data acquisition, you will need to install NI-DAQ drivers. If you are doing image acquistion, you will need to install NI-IMAQ drivers.
All these drivers are available for downloading on ni.com. To get the drivers, go to ht
tp://www.ni.com/support , click on the link that takes you to Drivers and Updates (under Option 3), and click on the links to get to the driver(s) you need. For example, if you need the LabVIEW 5.1.1 Run-Time engine, click on the All Drivers and Updates by Application link on the main page (http://www.ni.com/softlib.nsf/). Then click on the LabVIEW link, Windows 2000, Run Time Engine, and then you will see the link to get to the page to download the LabVIEW 5.1.1 Run-Time Engine.
I hope this information helps.

Wilbur Shen

What is your question? You've described what the program is supposed to do, but it's not clear what you're asking about. Do you need help getting started? If so, have you gone through the LabVIEW tutorials? You and look over the material in the NI Developer Zone's Learning Center which provides links to other materials and other tutorials. You can also take the online courses for free. Have you looked through the many examples that ship with LabVIEW for data acquisition?

I need a solution for a lab view apllication and installer problem

I ,ve already deployed an application and an installer, when i run the executable and the installer on my laptop it run well,
but when i run them on a computer that does'nt have a labview it gives me a messege says that i need to install the labview run time engine 8.5
actually i 've included the run time engine to the installer and i 've installed the run time engine from labview 8.5 cd,
but it still give me the same messege.
information you might need:
I'm using in my project the following:
-network shared variable
-data base connectivity functions
-report generation functions
-visa functions
so if any one can help me with this up?????????

LiveCycle forms use a very different approach to create a PDF form than Acrobat and that approach makes many features for processing PDFs non-functional.

Create test sequence from lab view - add it to the .seq file

Hello All,
I have a query. consider an test sequence that has already stored in "Test.seq" format. let us say we have 5 test steps.
now is it possible to add a new test step to this existing test sequence using Lab VIEW. I mean if we enter a new test step this has to reflect in the existing test sequence "Test.seq". i.e in the "Test.seq" we must have 6 test steps.
If this is possible let me know how this can be done.

Michels,
Guenter mande a very good point. Make sure to take a look at the forum thread he linked to see the licensing implications of creating your own Sequences.
There is a very good forum thread that discusses how to create steps programmatically. You can find the forum here:

Versions of lab view

Hi:
Just a few days ago i put this message:
Hi:
Im trying, to find a way to search, a file stored in different subfolders of a main folder, and copy, i mean i have a VI which makes a folder everyday (the name istoday date, or yesterday date), and inside that folder is a serial1.txt log file, but yesterday (for axample) the same log file (serial1.txt) was generated, how can i search in lab view all of those serial1.txt files?? By putting just in the search field, the main folder name???
And I want to copy each of these serial1.txt, to different paths???
So in this days, i ve working and the file is ready, but this archive just search like this: main directory /2nd directory/ 3rd directory/Files.... I mean if the files is deeper in more subdirectorys, does not work well works for me.
Im working in lab view 8.5 but, when i tried to put the .exe file in the computers where i have to look for my files, sorprise!!! the computers have the version 7 express or somethig like that so i cant use my file. IT Is possible change the version of my file to version 7?????

I don't know if you are still asking the same question in this thread or not. If you are, don't start a new thread.
As far as the exe, all you have to do is install the 8.5 run-time engine on the other PCs. If you had created an installer (something you should always do), the run-time would have been included.
