Error -200220 LabView 7.1 USB 6008

I have two PC one with LabView 7.0 another one with LabView 7.1 and NI-DAQmx Base 1.4 installed for USB 6008.
If I run example VI for LabView 7.0 on first PC it works OK, but on second one I get Error -200220 occurred at an unidentified location Possible reason(s):
Device identifier is invalid.
Can someone explain me what to do with this error.
I already tried to update LabView to 7.1.1. and drivers to 7.5 but things are getting even worse with it so I reinstalled all back.
Can somebody give me simple VI example for this device (for examle AI monitoring) and may be you can help me with this error.
Sergey.

Sergey,
If i'm being totally honest, I would ditch DAQmx Base and move to DAQmx 7.5, in the long run this will make things ALOT easier.
From your previous post, I'm guessing you already have 7.5 downloaded or on disc somewhere. Install this driver instead. The following guide may help you out:
http://digital.ni.com/manuals.nsf/websearch/5F6EEBAF2522C98B862570120052F35F
As soon as you run into any problems, let me know by posting here and I will work through them with you.
One other thing I would mention is that you may be experiencing problems that have arisen due to multiple install/uninstalls, and the registry may have been mixed and that's why you are having the trouble.
Let me know how your getting on and we can progress together!

Controling heating/cooling element with labview and usb 6008 DAQ card

Greetings All
I'm looking for a heating/cooling type of element that I can control with labview and my usb-6008 card. Heating/Cooling will just be for clean water and the temperture range will be from 0 C to 100 degree C.
Thanks
The heating and cooling elements can be seperate products. Any recommendations

A simple kettle element will of course be sufficient for upto 100°C
To get the temperature down you need a cooling system, what springs readily to mind of course is a refrigerator.
Just a note of warning, water and electricity are dangerous bed fellows.
On that note perhaps one of those vortex air units would be safer - they blow hot in one direction and cold in the other, nominally to 100°C

PWM control through USB 6008/09

Hello all
I have already read a thread regarding the topic but i am not satisfied with the replies.
I have discovered few programs that can run PWM in LabView, but they all are for DAQmx. So, will those programs run through USB 6008? and i also read that the output will be a sort of slow response output?
I am aiming to power a micro-pump rated at 12VDC. So, i want to run the program in LabView, use the USB 6008 to connect to a the DC motor. I know that some amplification will be required because the output of the USB 6008 is rated as 0-5V.
But, my question is can i successfully control the speed of the DC micro-pump ( motor) using the USB 6008??
Regards
Nikhil

Thanks for the reply.
If you just need to output voltages(not PWM) then you can use the Analog outputs of the 6008,
Analog Output
Analog outputs........................................2
Output resolution ....................................12 bits
Maximum update rate .............................150 Hz, software-timed
Output range ...........................................0 to +5 V
Output impedance...................................50 Ω
Output current drive................................5 mA
Power-on state ........................................0 V
Slew rate .................................................1 V/μs
Short circuit current ................................50 mA
Absolute accuracy (no load) ...................7 mV typical,
36.4 mV maximum at full scale
So yes you could output a voltage between 0 and 5 Volts. You could only change the voltage level every 10ms or so.
In answer to what your device (pump) requires I don't know.
"So, this got me thinking, do i really need PWM control for the micro-pump (DC motor)?"
Have you got a specification datasheet (website) of the pump? - I dont mind taking a look.
Have you looked in the NI Example Finder to VIs that generate PWM and AnalogOutput (AO?). In the example finder (help>>Find Example) it gives you information on what devices can use the examples - simply look for the ones which say usb6008.

Error -10401 occurred at AI Group Config - in relation to USB-6008

I'm attempting to run a simple vi that uses AI Aquire Waveforms.vi to input voltage data that I have coming in from the USB-6008 DAQ. However, when I try running the program, I receive the error:
Error -10401 occurred at AI Group Config
Possible reason(s):
NI-DAQ LV: The specified device is not a National Instruments product, the driver does not support the device (for example, the driver was released before the device was supported), or the device has not been configured using the Measurement & Automation Explorer.
And I'm not sure how to fix it. In MAX, the device seems to be working properly and everyhting seems to work fine in the test panel, so I'm slightly at a loss. I'm running Labview 7.1, and installed NI-DAQmx 7.5 which came with the USB-6008.

Never mind. I'm new to Labview, and didn't realize that I could not use the traditonal Data Aquisition components with the USB-5008 (I didn't even realize that NI-Daqmx was different).

How can I make LabView 6.1to detect DAQ NI-USB 6008

I have a LabView version 6.1, recently I bought a new DAQ model NI-USB 6008, I could not use it with my Labview version. Please, how can I adapt my DAQ for version 6.1 or update my LabView to detect my DAQ? Please advise me to a free applicable solutions. Thanks very much

The USB 6008 requires DAQmx which requires LabVIEW 7.0 or greater. The upgrade to 7.x (or the just released 8.0) is not free. The only other solution I've heard of is to use the Call Library Function Node to make your own calls to the DAQmx dll. This would not be for the faint of heart or anyone wishing to come up with a quick solution.

Are USB-6008 drivers available that make it compatible with LabVIEW 6.1?

I'm using a USB-6008 Multifunction DAQ, but it is not compatable with teh version of LabVIEW I'm using, 6.1. I may be able to upgrade to LabVIEW 7.1 to solve the problem, but I wanted to know what alternatives I have. Are there any available drivers or patches that allow the USB-6008 to be recognized by LabVIEW 6.1?

Unfortunately, no. The driver for the USB-6008, DAQmx Base 1.5 is only compatible with LabVIEW 7.0 or newer.

I have LabView Student Edition, how can I make work a USB 6008?

The Student edition it doesnot have many Vi's that there are necesary to work with a USB 6008, I would like to know how can I make work the Usb 6008 with LabView Student Edition

Hello Jorge,
When you say "NI-DAQmx configuration" do you mean the NI-DAQmx Base Configuration Utility? Are you using NI-DAQmx or NI-DAQmx Base to communicate with the 6008?
NI-DAQmx 7.5 added support for the USB-6008. Therefore, you can use either NI-DAQmx or NI-DAQmx Base to control this device. Make sure that you are setting the USB-6008 to NI-DAQmx before trying to use the NI-DAQmx VIs in LabVIEW. To do this, Open Measurement and Automation Explorer (MAX) and select Tools >> NI-DAQmx Configuration >> NI-DAQmx USB Driver Selector. Your USB-6008 should appear in this window, indicating which driver your device is configured for. Make sure it is set to NI-DAQmx before trying to use the NI-DAQmx VIs.
When your 6008 is set to NI-DAQmx, you cannot use NI-DAQmx Base or any of the DAQmx Base examples. Likewise, when the 6008 is set to NI-DAQmx Base, you cannot use any NI-DAQmx VIs.
If you would like to use NI-DAQmx with your USB-6008, please set the driver by following the steps above and verify that "USB-6008" is listed under "Devices and Interfaces >> NI-DAQmx Devices" in MAX.
I hope this helps. Please let me know if you continue having trouble with your USB-6008.

Sean C.

PWM por USB-6008 en Labview 7.1

Saludos a todos, mi problema es que necesito controlar 5 servos de un brazo robot que ya tengo armado y quiero sacar las señales PWM por medio de la USB-6008, solo dispongo de Lavbiew 7.1, ya genere las señales pero no tengo la menor idea de como enviarlos, por favor si tienen algun ejemplo les agradecería que me lo colocaran como imágen pues no puedo ver los ejemplos de versiones mas recientes de Labview, gracias por su pronta respuesta ya que debo entregar el proyecto antes del 15 de noviembre y es requisito para mi graduación de Ingeniería Electrónica.

Hola Coky aquí el problema es en sí que estás trabajando fuera de las especificaciones de la tarjeta 6008. Esta no cuenta con un reloj interno por software por lo que tanto las salidas y entradas digitales como las analógicas están controladas por software. El control por software lo mas que te puede dar es un loop de 1ms, por lo que en el periodo de 1ms que quieres madamas podrías actualizar la señal 1 vez. La velocidad que puedes alcanzar por software es de 1khz.
Mas que utilizar dos tarjetas 6008, te recomendaría utilizar una tarjeta más completa por ejemplo una que utilice contadores, o una tarjeta mas rápida como la NI USB 6211, que además cuenta con contadores y te permite trabajar a 250kS/s, y el timing interno es por hardware.
Otra opción es que a través de tus salidas digitales controles componentes como un 555 y que con este controles tu servo.
Saludos

Can I use USB 6008 with LabVIEW 6.1 RT?

Hi there,
I've been using LabVIEW 6.1 RT for my applications and so far I haven't felt the need to upgrade.
However, I decided to try the USB 6008 and I'm learning the hard way that this device will only work with NI-DAQmx and apparently not with the latest NI-DAQ 7.4.2 (legacy) In fact, I can't see the device in MAX 4.1
Is there any way I can use the USB 6008 with my 6.1 RT version of LabVIEW ? or should I send the thing back to NI ?
I will appreciate your guidance on this issue.
Thanks a lot,
at

Hi at -
Allisso is right. There is no way to use the USB-6008 with LV 6.1, because neither of its drivers (DAQmx and DAQmxBase) support that version of LV. You'll have to either upgrade to a current version of LV or work with another device. I recommend contacting your sales rep at NI for help.

Making another counter VI for usb-6008 using Labview 8.5

I want to create another counter for usb-6008 using Labview 8.5 as it is needed to calculate two speeds simultaneously.
Solved!
Go to Solution.

The best way to do this is to use the counter. The counter counts
signals without having to interrupt the system or use the USB bus.
When you request the number of ticks that the counter has seen, a
request is thrown from the CPU to the USB line to the 6008, which then
asks the counter "How many ticks have you seen?" That number is
returned over the USB bus, goes to the CPU, and then displays on your
screen. Since the DIO lines on the 6008 are software timed, there is
no way to guarantee that the data returning to the CPU is
deterministic. The conceptual difference between software-controlled
DIO (which nondeterministically returns an entire data stream) and a
software-tick-request-controlled counter (which returns a single number
with the number of ticks) prevents us from using the DIO lines on the
6008. The cheapest way to count more edges is to purchase more 6008s.
Another possibility would be to purchase a PCI counter board such as
the PCI-6602, which has 8 counters. The most counters we offer in the
USB form factor is 2 per device.

DC motor closed loop control through labview using usb 6008

Hello
i am doing a project in which i want to control the speed of a DC motor (PID control) through labVIEW 2010. I am having a DC motor, a drive unit that regulates the voltage to the motor by getting analog voltage from 0 to 3.3V ( it can be used for both directions) and i also have a NI usb 6008 board. The problem is that i can't feed the usb 6008 with the digital signal from my hall effect speed sensor. Is it posible with this setup to control the motor?? I can also try to use the pulse as analog input and trasform the frequency into rpm's. Then i am thinking of generating an analog signal to feed the motor drive. If you have any further suggestion of a probably better hardware setup would be more than helpfull to me.
Sincerely
Jason Chaloulos

Hello Michael
Thanks for the reply. I came across those topics before and all of them are trying to generate a PWM signal as output i want to use just an analog signal output so timing on the output is not that important i guess. i am struggling on getting the frequency from the digital input signal that my hall effect sensor generates. Since the maximum speed of the motor is 3000 rpm and with my tooth wheel the maximum output frequency of the sensor will be 300Hz which i see its way less than the limitation of my ni board. Is there any tutorial documentation that might help me with this one ? Thank you in advance.
Kind regards
Jason

Labview 6.0 Vs USB 6008

I have labview 6.0 software and I was wondering if it is compatible with the new USB 6008 data acquisition boards.
Thanks.

No. The minimum version that you can use is 7.0.

Does USB-6008 student kit come with a LabVIEW 2009 textbook?

Hello.
I'm taking a LabVIEW class that requires the "LabVIEW 2009 Student Edition" textbook and software on DVD. I want to also get the USB-6008 Module, too.
Browsing the NI Academic Starter Kits, I came across the USB-6008 Student Kit, which says comes with the USB-6008 Module, LabVIEW Student Edition software, and SignalExpress LE. This Kit seems like the best package for me to purchase, but the website is not clear as to whether the textbook is included. Does anyone know if the book is included with the USB-6008 Student Kit?
Thanks,

Hi YTrunner,
Thank you for contacting National Instruments. I can confirmthat the 6008 starter kit does not come with the textbook. You would need to purchase these products separately.
Many thanks,

Device identifier is invalid error 200220

I developed a program on one computer using LabView 8, DAQmx 8 and a USB-6008 device. It worked fine at my desk. Then I save the program as a project sent it acroos the street to our shop, took the device over there plugged it in and tried to run the program. I got a 200220 Device identifier is invalid error. When I pull up MAX I can see the device and if I build a tsk on that computer for that device it runs fine but it will not run the program that I brought over from my desk computer. Any Idea what I'm doing wrong?
TIA
George

Munir,
I'm sure some of the other can better answer your question as I too am a LabView newbie, but I'll tell you what I know.
1)What is the Development system. How can I know if both are Device1 or whatever is appropriate.
My development system was my desk computer, I used another PC out in the shop as a deployment computer to attach my DAQ device and run my program.
2)I am using examples for LABVIEW.
The examples are code that someone wrote on another machine so the device that they specify might not be the same as the one on your machine.
In my case my USB device that I was using as my DAQ was named Dev2 on the computer at my desk that I wrote the program on. However when I took the DAQ device down to the computer in my shop to run the program it was named Dev1 because there were no other devices on that computer. There was no Dev2 on the shop computer so when I tried to run the code it crashed as it could not find a Dev2 to get the data signals from.
Tom's request of "If you can get screenshots of the NI-DAQmx Devices and Data Neighborhood trees from MAX that would also help."
would be a good place for you to start.
I hope this helps

Como controlar velocidad con un PID con USB 6008 ?????

Buenas tardes.
Acabo de adquirir mi placa USB 6008 y estoy comenzando a trabajar para poder controlar la velocidad de un motor trifásico asincrónico estandar.
Para esto contruí con un microcontrolador y una etapa de potencia la parte del variador. Y logré con esto que mi variador reciba una entrada de 0 a 5 Vcc y con ello varía la Frecuenci-Tensión de salida. Es decir solo necesito entregarle 0 a 5 V para que este actúe sobre todo el rango de frecuencias de salida.
También contruí una placa de aislación galvánica que separa absolutamente la salida analógica de mi USB 6008 con la placa del variador que construí, como para separar las masas y la señal y evitar inconvenientes en mi Notebook y placa de adquisición.
El feedback de velociodad lo hago con un sensor óptico y un disco dentado acoplado al eje del motor que me puede dar según mi necesidad 1 , 2 , 4 , 6 , 8 ó 10 pulsos por vuelta de acuedo a como lo ubique ó a mi necesidad.
Entiendo que la placa USB 6008 no es la mejor alternativa para trabajar a tiempo real, y mi sistema operativo ( windows vista x64) tampoco. Pero mi sistema es bastante inercial desde el punto de vista mecánico, y también lo es por la placa del variador que no tiene una respuesta instantanea por cuestiones de constantes de tiempo que le di al firmware del micro. Es decir que no necesito velocidad en el sistema ni en el VI que necesito desarrollar.
Resumiendo, necesito entrar a mi placa USB 6008 con pulsos ( los que se necesiten por cada vuelta del motor) y luego salir por una salida analógica ( de 0 a 5 V) con la información de velocidad que va al variador.
Tengo a mi disposición Labview 8.5 con el Control design & simulation que tiene incluidos subVI con PID's listos para usar.
En medio de este sitema, necesito generar un VI con el que pueda dar una referencia de velocidad desde un potenciómetro virtual en mi panel frontal, y que el PID en el programa de Labview corrija errores de velocidad por alguna pequeña variación de la carga, etc.
La verdad que estuve probando hacer un VI con un PID bastante simple, pero a la hora de simularlo, fuí modificando los parámetros del PID y no vi que se haga "mas inercial"cuando aumento el tiempo integral. Tambien probé salir de mi placa con una tensión analógica, y dar una referencia con un potenciómetro como para probar si el PID se hace mas "rápido ó lento" al modificar las variables Integrales ó derivativas y no vi variaciones en la respuesta.
Por eso es que pido ayuda en este foro, ya que probablemente alguien ya hizo alguna prueba, o me puede indicar como arrancar con este tema.
Este proyecto es solo con fines académicos, para mi tesis de Ing. Electrónica. Por ello el motor no tiene carga, solo el disco dentado y el sensor óptico, solo lo puedo frenar un poco para ver la corrección.
He comprobado que saliendo de mi placa 6008 con una señal analógica, pasandola por una placa que simula un retardo en el tiempo de esta señal, y reingresandola a una entrada de mi placa 6008 para luego con un VI generar el PID y tratar de que esta señal de entrada a la placa 6008 sea igual a la de setpoint, solo logro oscilaciones con una media que está lejos del valor del setpoint.
Espero que alguien me pueda indicar como empezar, ó darme algún ejemplo que me pueda ayudar, ya que no soy experto el Labview, solo acabo de empezar a usarlo.
Reitero que no necesito velocidad ya que mi sistema es lento, y solo debo variar mi salida analógica con velocidades muy bajas. Es decir no necesito respuesta inmediata.
La idea es hacer una demostración del uso de un PID en un sistema real con Labview.
Saludos...!!!!
