Verification of the data-acquisition process

Hello,
my name is Andreas and I'm a beginner in LabVIEW programming.
My task could be described as follows:
I have on data signal to acquire with the PC-DIO-32 Acquisition Card.
I have also the connection block SCB-68 to connect my application.
What is my application:
"clock one": is a 166kHz clock trigger clock ti= 200ns tp=5.8us
"clock two": is a data stream signal binary signal (patterns of 0 and 1) data stream of a Random Generator
Each time when a positive edge of the clock "one clock" arrives the DIO 6533 has to be store the signal of
the "clock two" data in a binary file.
I chose the " Burst" - mode example in external trigger clock conditions for my application:
and I use the SCB-68 connections:
PCLK1 (connector 5 of the SCB-68) is the connection for my external trigger clock "clock one"
ACK1(STARTTRIG1) (connector 3 of the SCB-68) is connected to 5+ Volt (connector 1 of the SCB-68)
REG1(connector 2 of the SCB-68) is connected to 5+ Volt (connector 1 of the SCB-68)
The port data output of the VI DIO-Read is connected to the data input of the VI Write File!
The program seems to work fine but I can't verify if the acquisition card takes the data of "clock two" really
at that time when the rising slope of "clock one" arrives!
To solve that problem I did the inverse option of the "burst" mode-> Pattern generation using an external clock at PCLK!
So I took my clock "clock one" fed to PCLK1 and I started the program!
Bad, it didn't work! Problem with a buffer configuration ERROR -10022!
So I will send you my program to give you an idea of my design problem!
If the "burst" - mode is not the best way to solve my application problem I would like to know in which mode
I should adjust the card to solve my problem!
Furthermore it would be great to get a programming example in which I can observe if the data is taken by the card
each time a positive slope occurs!!
Thank you very much for your help,
Andreas
P.S:
It is not easy at all to find your answer in your whole database! So if possible send me your answer to

Thank you very much toddd,
is seems to you that I'am a real looser.
But if I use the Pattern Input vi with the DIO 6533 I still not able to verify if the stored or screened data (see the graph vi in my example)is really that one which should be acquired by the card!
Let me explain:
You have NRZ-signal generator which output you can switch on or off.
You may connect your data-stream which you want to store into the DIO card to DIOA0 (connector 10 at SCB-68).
Your NRZ-signal from the generator is fed to REQ1 (connector 2 at SCB-68).
Now you will start your labview program. I set a timing delay at Read vi of 25sec.
I also monitored the data-stream of DIOA0 and the trigger signal at REQ1 using an oscilloscope.
(the trigger of the osci is set
to single mode , leading edge for the osci-channel which is connected to the trigger signal at REQ1)
Now I switch on the output of the NRZ-signal generator to on.
Now you can see at the screen of your scope some trgger pulses an the data-stream.
At each time when the trigger signal positive slope rises the data(0 or 1) at DIOA0 must be stored!
Problem: the detected data on the scope screen are not the same wich I stored in the DIO card!!
Todd, could you tell me what I did wrong?
And again, many thanks for your message!!!!!

Data Acquisition Step Type

Hi, is there a step type to perform Data Acquisition and Basic comm control such as RS232 and GPIB within teststand ?
This question was raised when I was training one of our Technicians today, he asked/suggested that having a step type which performs Data Acquisition and comm control would reduce there development time down dramatically, They have just started to use Teststand on small cycle test rigs as part of an evaluation stage. They have no experience with LabVIEW or CVI, they basically want a quick and easy way to produce a test sequence with Data Acquisition and comm control.
if there is anything like this at the moment can you possibly reply. If there is not, is this a something which will be avaible in the future ?

Data Acquisition usually refers to a DAQ board from NI so I think what you are looking for is a generic NI-VISA step type and a specific RS-232 step type. I have a NI-VISA step type that was originally written with LabVIEW 6.1 and for use with TestStand 2. I've atached that below. I don't have the .ini file handy and don't have time to recreate it but from the code, you should be able to see what needs to be added to the step properties. The basic step is a modified Pass/Fail Step.
It's not that difficult to create your own custom steps. I've done a lot and it only takes a little while longer than doing a code module in LabVIEW or CVI. The extra time is in creating the edit step.
I've got an RS-232 step type but part of it is product specific so it is proprietary and I can't post that. Look at the VISA example and the other examples of custom step types that are on the developer zone and see how far you get.

Data acquisition: task specified does not exist

I am trying to do an analog read. Apparently in the original code (which I did not write), the data acquisiton is a multithreaded task. (I am not a real programmer, so know next to nothing about multithreading, and not a whole lot about programming)...
When I tried to collect data (by pressing our "Data Collect" button on the GUI, I got an error along the lines of:
"Task specified is invalid or does not exist. Status Code: -200088"
I have figured out that the task the error refers to is called SetCollectData, for which I am not able to find a definition.
It runs fine when I comment that line out, but of course, no data gets collected!
Here is the actual data acquisition portion of the code:
if(DAQInputTask && ) GetCollectData())
               if((AiData = malloc(sampsPerChan*AiNumChannels*sizeof(float64))) == NULL )
                   MessagePopup("Error","Not enough memory");
                   goto Error;
               DAQmxErrChk(DAQmxReadAnalogF64(DAQInputTask,-1,0,DAQmx_Val_GroupByScanNumber,AiData,sampsPerChan*AiNumChannels,&numRead,NULL));
               fwrite (AiData, sizeof(float64), sampsPerChan*AiNumChannels, AiRawData);
       *AiData = NULL;
Any ideas?
I have switched to NIDAQmx drivers, and have had a host of problems since switching to DAQmx functions. So, this new problem may still be related.
Thanks!

Tasks in CVI are the basic of data acquisition: every operation is run under a task which groups channel definition, triggers, acquisition rate and almost every other element which constitues an acquisition process.
You should try to find informations about the tasks used in your project, possibly asking the original programmer; on the same time, you should learn some infos about how daqmx treats data acquisition process. Here you can find the help page related to tasks: I suggest you read that page and use it as a starting point for your search. Keep in mind that a task can be defined either inside the program or within MAX. One possible cause for not finding the task while running the program is that is has been defined in MAX on one machine and you have moved the project to another one without moving MAX informations too from the original PC, but this is only a guess.
It's not clear from your words whether you are modifying an existing project developed in DAQMx from the beginning or you are moving an old NI-DAQ project to DAQMx. These are very different scenarios. In every case you should see the exact line where the error arises, look for the task handle used in that line (e.g. 'DAQInputTask' in the code you posted) and find the line where the task is loaded/created (ultimately try a search for that variable name in all your source files and examine each line where it si used).
Proud to use LW/CVI from 3.1 on.

Data acquisition time of ocean optics spectrometer

Hi, LVers,
I has a S2000 multichannel fiber optic spectroscopy system. It includes two channels, master and slave. Additionally there is a channel labeled as 'LS-1'. I use labview and driver OOILVD32.dll to control this spectroscopy. In OOILVD32.dll, I use vi 'OOI SCAN' to acquire spectral data through master channel.
In vi "OOI SCAN", I disable all slave channels (there are 7 slave channels) and enable master channel only. However, I find that the data acquisition time is always approximately two times of the "sampling frequency" we set. E.g. for sampling frequency of 75 ms (a small value), the spectral data acquisition time is approx. 160-170 ms; for a sample frequency of 4000 ms (a large value), the spectral data acquisition time is approx. 8300-8400 ms, so on and so forth.
I am very confused with this phenomenon. I guess the most probable reason is that both master and slave channels are always enabled even one of them is software disabled. Because this product is discontinued, I can not find the manual. Anybody could advise me how this such a spectrometer works internally? Is there any multiplexing acquisitions inside?
Thanks in advance.

Hi Hello183,
Unfortunately, I do not know how your specific device works, however, I did find the product page for this device on the Ocean Optics web site, which points to the USB4000-series Plug-and-Play Spectrometer for more details. There seems to be a operations manual for this device. Perhaps this can shine some light on how the sampling works for your device as well.

The ADO NET Source was unable to process the data. ORA-64203: Destination buffer too small to hold CLOB data after character set conversion.

We developed a SSIS Package to pull the data From Oracle source to Sql Server 2012. Here we used ADO.Net source to pull the records from Source but getting the below error after pulling some 40K records.
[ADO NET Source [2]] Error: The ADO NET Source was unable to process the data. ORA-64203: Destination buffer too small to hold CLOB data after character set conversion.
[SSIS.Pipeline] Error: SSIS Error Code DTS_E_PRIMEOUTPUTFAILED.
The PrimeOutput method on ADO NET Source returned error code 0xC02090F5.
The component returned a failure code when the pipeline engine called PrimeOutput().
The meaning of the failure code is defined by the component,
but the error is fatal and the pipeline stopped executing.
There may be error messages posted before this with more
information about the failure.
Anything that we can do to fix this?

Hi,
Tried both....
* Having schema type as Nvarchar(max). - Getting the same error.
* Instead of ADO.Net Source used OLEDB Source with driver as " Oracle Provide for OLE DB" Getting error as below.
[OLE DB Source [478]] Error: SSIS Error Code DTS_E_OLEDBERROR. An OLE DB error has occurred. Error code: 0x80004005.
[SSIS.Pipeline] Error: SSIS Error Code DTS_E_PRIMEOUTPUTFAILED. The PrimeOutput method on OLE DB Source returned error code 0xC0202009. The component returned a failure
code when the pipeline engine called PrimeOutput(). The meaning of the failure code is defined by the component, but the error is fatal and the pipeline stopped executing. There may be error messages posted before this with more information about the
failure.
Additional Info:
* Here the Source task is getting failed not the conversion or destination task.

E5-571 PCI Data Acquisition and Signal Processing Controller & SM Bus Controller

I upgraded from Windows 8.1 to Windows 10. Windows Update says that it is up-to-date. Windows Devices Manager shows a problem with two devices: PCI Data Acquisition and Signal Processing ControllerSM Bus Controller What are these devices and where do I locate the drivers for them?

That should do it. I've been pleasantly surprised by how well older drivers are working in Windows 10. I had to install Vista 64bit drivers for an ATI video card (the latest working drivers for the card) and they actually worked!

Lenovo 14 20DM correct driver for 'Data Acquisition and Signal Processing Controller'

Hi Everyone, I am the happy owner of a new Yoga 14 20DM. A few days ago I made the decision to upgrade to Windows 10. Whilst the upgrade went smoothly I did have to install a number of drivers manually. At the moment I am stuck on trying to install the 'PCI Data Acquisition and Signal Processing Controller' (as shown below). I have tried right clicking on the device then selecting Properties > Driver (tab) > Update Driver > Search automatically for updated driver software, however doing so only shows the screen capture below! Furthermore I have searched the Lenovo support page for a suitable driver however none is available! http://support.lenovo.com/au/en/products/laptops-and-netbooks/thinkpad-yoga-series-laptops/thinkpad-yoga-14/20dm?TabName Finally I have also installed, and run, 'System Update 5' the software program available from Lenovo. However it was not able to install a correct driver for this device. I have done a little searching on this topic, and have read a couple of stories about people installing an incorrect driver for this device, and then experiencing blue screens! Can anybody suggest how I can go about locating and installing the correct driver for this device? Any help will be greatly appreciated. Kind Regards, Davo

Hi Ingemann, Ultimately I decided on the newest version of the Intel Chipset Device Software (INF Update Utility), which at this time (on the Intel website) is version 10.0.27. https://downloadcenter.intel.com/download/20775/Intel-Chipset-Device-Software-INF-Update-Utility- Interestingly enough I was presented with the message below when I ran this executable. I selected Downgrade (with some trepidation), and after rebooting was pleasantly surprised to see that the troubled device was missing from the list. I can only assume that this means the correct drivers were installed. Thanks you very much for your help. Kind Regards, David

Data acquisition in automotive crash test

I need information about hardware and software NI tools for develop a data
acquisition system

NI has a very broad range of tools that would fit this type of application. Identifying which tools will fit your needs will require a more indepth specification of system parameters. I highly recommend that you use the on-line DAQ Designer at http://www.ni.com/daq/ddonline.htm. If you prefer you can also enter a conversation on-line by following the "Ask an Expert" link at the bottom of any on-line catalog page.

How to writing the data into the file at the same frequency of data acquisition using myRIO

Hi everyone,
I have a question regarding data acquisition fequency and data recording frequency of myRIO. Hope you guys can help me out.
Basically, I want to acquire voltage input at analog input 0 at the frequency of 1kHz and then write the data into a file (tdms format).
However, I always found there were only 55 or 56 data points recorded every second in the data file (see the excel sheet).
To confirm my data acquisition was performed at the correct frequency, I added a small function in the main loop to indicate the time spent between two acquisition events.
To my surprise, the period of data acquistion is correct (1ms or 1kHz) but there are only 55 or 56 data point per second recorded in the data file.
How can I record every data point acquired by the analog input?
Thank you!
P.S. I am very new to myRIO. How can I manually set the system time for myRIO? The default time of my myRIO is wrong.
Best,
Tengyang

Top level application structure with parallel data acquisition

Hey all LabVIEW-forum members!
I have some experience programing LabVIEW, but mostly concerning smaller for the simplest form of data acquisition. Now I need to develop a larger application that might be continuously run for several weeksin a row and for that reason I woiuld like to make sure the application structure is stable! I turn to you in hope of some input regarding the most suitable approach to my problem or some pointing in a good direction.
-The project involves making hardware communication with a few different hardware interfaces, such as GPIB and NI’s DAQ-card (analog and digital reads/writes on PCI-6221).
-Save acquired data to disk.
-The communication and data save are based on condition of elapsed time (for example there could be a need to make parallel analog measurements med DAQ-card every 5th minute but GPIB-measurements every 30th second).
-At the mean time I would have to regularly the status of the test object and update the user interface. (However, while in test the user won’t be allowed to interact with the application other than to monitor the UI or pause the test).
The project isn’t really time critical (in case I need to make one type of data-acquisition while another one is already initiated, they can be carried out in sequence).
I’ve started with programmatically control the user interface by using the “Top Level Application Using Events”-template and produced code that will let the user set up a new test or load an existing test. All the data concerning the status and configuration of the test I’ve saved in two clusters that can be passed along to different events.
I’ve reserved one subdiagram in the event structure for the actual execution of the test. It is the structure of this subdiagram I am a bit confused about…
Could I use another while-loop/event-structure inside this subdiagram and use user-registered events for the different data acquisition? Or is there some type of state-machine that is better suited to monitor time elapsed and can make a transition to a suitable state when it’s time to make any of the hardware measurement required? It would be nice to avoid using polling loops but maybe that is best way to go?
I’ve checked the “Continuously Generate Occurrences.vi”-example and that might be a way to go? What seems to be good with this approach is that I could let the different parallel hardware acquisitions actually be parallel, right?
I am really confused right now, hope someone has some helpful inputs!
Regards
Oscar

This post here can be proved as a great starting point for your application.
