Scheduled data acquisition

hello
every body
my task is scheduled data acquisition. which is the efficient method to do that,
for example
i want to start the acqusition in the morning 9.pm and finish at 10.30 p.m and save the data in a file and wait for next acquistion it starts at 11.p.m and end at 12.30 p.m . like that i want to do.where the start time and end time i will give in a data file ok.
by continously watching the system clock i can do but . can u give some efficent method of doing that.

First, a couple of questions.
Are you running on a windows platform
Are you building an EXE?
I am sorry I am late to respond, but I needed to test this before I recommended it. If the answer to 1 is yes, you can use the windows task scheduler to launch your app and make your acquistion. If the answer to 2 is NO, then your cmd line switches will need to be a -- instead of whatever you like. You can read a file, if need be, to determine the length of the acquistion. The biggest benefit to this approach, is that you can have the system run this task, even if you are not logged in! Usually IT hates it when you leave domain computers logged in! And best of all, NO system resources are spent, no background app is running, and consuming whatever resources are required. Granted, there are not much given the suggested approach, but yet another app (one with a front panel open somewhere) running. I do not know about you, but I try to minimize the number of processes running at any given time. I have tested this, and even brought my computer out of hybernation and sleep modes to run the app! That is fantastic. I hope this helps.

Differences between BW3.5 and BW7.0 Realtime Data Acquisition

Hi,
Could any one explain me clearly the differences between BW3.5 and BW7.0 for Realtime Data Acquisition and also steps for creating it in BW7.0.
Eagerly waiting for your reply. Thanks in advance
Anan

You have to create tranformation in between your DSO and datasource.
If u have not done init of delta earlier, create Standard DTP and schedule init load.
If you did already, create or convert(if standard DTP already exists) Real time DTP. Now create infopckage with realtime field enable, and follow the steps of my blog on demanon from here onwards.

Driver missing - PCIe Data Acquisition and Signal .....

Hello, i recently used Boot Camp to install Windows XP on my 2010 15" Macbook Pro.
All the drivers are working (so far) and i haven't encountered many problems.
However, there is one thing bugging me:
When i go into Device Manager in Windows, and look down the list of installed/uninstalled devices, there is a device called "PCIe Data Acquisition and Signal Processing Controller" which has no driver installed.
I'm PC savvy, but i have never seen this before. My guess is that one of the motherboard drivers is missing, and Boot Camp installer doesn't include that driver?
Has anyone seen/resolved this, and if so, how?
Thanks.
Kaj.

Okay, will do.
Thanks.
Also i wonder if you could help with another problem?

Data acquisition from SR 530 lockin

Hello,
I need to read the output of the sr530 vector lockin and store them in a file.
I was wondering if there is any driver which will let me read frequency, output amplitudes & relative phase between the input & output signal!
Any help will be much appreciated!
Thanks a lot,
Ashutosh.

Thanks a lot for the help Matt.
I can connect the device via GPIB. Let me tell you a bit more about the problem. As of now I was using a single channel lockin, EG & G 5209, to read the data(so I am kindda familiar wtih data acquisition... not much though). And the only thing I was reading was the output amplitude of the lockin.
Now I have to use the vector lockin, SR 530, and I will need to read both the output amplitudes, the phase & the frequency (all four of them)at the same time. And I am looking for a driver which can do this, i.e. which can read all four data simultaneously & store the result in a *.txt or *.dat file.
Do we have something like that?
Thanks,
Ashutosh.

Data acquisition in a state machine

I've recently learned how to implement state machines, but I have a question that I haven't been able to find an aswer to.
Question:
How do I record uninterupted data (presently i'm using the DAQ assistant to record a single channel at 10kS/s at 1kS intervals) without interfering with my state machine?
Background:
I have a time sensitive test setup (measuring pressure in a rocket chamber), and I'm using labview to both record a single pressure transducer as well as operate the valves (O2, N2, igniter, etc). I'm using a state machine Labview architecture (just learned how). Presently, the DAQ assistant sits in the "Idle" state, and timers (valves need to be turned on at specific times) and manual buttons control when the other states are activated. I have a 10ms timer controlling how often each state is run, and this is the root of my concern.
Main concerns:
I'm worried that:
1) I'm forced to change my data recording to 10ms intervals to match the 10ms timer, and
2) The 10ms timer will interrupt my data recording when it's in another state.
It's very important that the pressure data is recorded without interruption but that I have high time resolution in controlling my valves as well.
Thoughts:
1) Maybe I put the 10ms timer in the "Idle" state only, and this way the other states won't interrupt the data acqusition
2) Maybe there is a way to completely isolate the state machine for controlling the valves and the data acqusition. I'm not sure how to do this.
3) People on the forums have been talking about Queuing their data acqusition, but I'm not sure how this would benefit my situation.
Thanks to everyone for their feedback!

The data acquisition and state machine timer do not have to be equal, you should however have the same data write rate as you have data read rate, otherwise over the course of long running programs you can build up a large buffer of data to be written using a lot of memory, or lose data.
Your data acquisition should be continuous, the most common way of doing this is every time you receive data write it to a queue, then when you are in other states except your data write stage you simply build up data in the queue that is to be written when you enter the write state again.
Think of it as traffic reaching a set of lights:
The traffic represents the data acquisition, there is a constant flow of it always coming through, the state of your state machine is the lights, green is the data write state clearing the queue, red is when in any other state, letting the traffic build up behind the lights.
It is just important that the light is green long enough to let the traffic not build up too much, otherwise you have a jam.
EDIT: For the basics of how queues work, look at the Queue basics example from the example finder.

Data acquisition from multiple channels.

Hello
Right now, I am able to acquire the signal from a single load cell and display it.But I would like to know of how to acquire acquire signals from two load cells simultaneously.I am using Labview 6i and I am using AI S-Scan with AI config to acquire the waveform.It would be of great help if you could suggest a simple method to acquire the signals.
PS: Please find the attached file used for acquisition from a single load cell.
Looking forward for your reply.

Hi Manasa,
If I understand what you are trying to do, it is relatively
straightforward to configure your application to acquire data on two channels.
I was unable to run your vi as it was missing some of the subVI’s
from your application. However, your
attachment was sufficient to see what you are trying to do.
Here is how to add channels:
1.
In the I/O Channel Constant, you can add
additional channels by using a comma or a semi-colon. For example, to scan the first four channels
you would put 0:3 in the constant (see attached screenshot ChannelConfig.jpg). To scan the first and third channel you would
put 0,2.
2.
The AI Single Scan VI will now read from
multiple channels. Often it easiest to
configure the output of this VI for viewing by first putting the data into an
array using the Build Array VI. It can
then be plotted in a waveform graph. (see attached screenshot ReadtoGraph.jpg
and WaveFormGraph.jpg)
Just a few notes about “simultaneous” sampling:
Most of the NI data acquisition cards have a multiplexer
between the various input channels and the Analog to Digital (A/D) converter
creating a very small delay between each channel (usually ms range or
smaller). NI does make several data acquisition
cards that can perform true simultaneous sampling, meaning that there is an A/D
converter for each channel.
For the large majority of applications, the small delay
between channels is negligible.

Data acquisition from switching 500lbs load cell to 100lbs load cell

I am using 500lbs load cell, and acquiring data by inputing 2volts from 2345 signal conditioning board, and sensor output is connected to SCC-AI03 pin 3 and 4 , and configure this load cell to a channel using NI MAX, data neighborhood, traditional NI-DAQ virtual channel, the physical quantity is voltage set at range -10 to 10, and sensor also set at voltage with no scaling, but, I couldn't get any signal when 100lbs load cell is use, the difference of this 100 lbs load cell is the rated output is at 2.958mV/V, while the 500lbs rated at 1.8295mV/V , how should I do this?
Thanks.

Hi,
At this point, it is difficult to determine exactly what is happening to your acquisition. Could you please provide some additional information by answering the following questions:
What voltage are you reading with the 500 lb load cell?
Would it be possible to connect your load cells to a DMM and see what voltage reading you receive? If so, what do you see?
What is specifically happening when you connect the 100 lb load cell?
I also noticed that you are using the Traditional NI-DAQ (Legacy) driver. I recommend upgrading to the NI-DAQmx driver. Here are a couple of links with more information about DAQmx:

Data acquisition driven by encoder

Hi everyone,
I need to sample a capacitive sensor that measures the radial run-out (radial small displacement) of a rotating spindle. LabView v. 7.1 is employed to acquire the data by means of PCI-6036E card commercialized by National Instruments (NI). The spindle rotates at 100 rpm and a rotary incremental encoder is fixed at rear of spindle. The encoder gives two types of digital pulses as follows: a) A-quad-B pulses (it will be used only “A” pulses in this experiment); b) index pulse (one pulse per revolution). This encoder provides 1024 pulses type “A” per revolution. The measurements made by the sensor are driven by “A” pulses which are used as “external clock”. Therefore, every “A“ pulse, the card acquires one sample from sensor. Thus, 1024 data/rev are acquired. I want to sample 5 consecutive revolutions of the spindle. To start the data acquisition, the index pulse of the encoder is used as “start digital trigger”. Also, the index pulse should be used to count the number of revolutions of the spindle. In this way, when the number of revolutions is equal to 5, the data acquisition finishes. By contrast, the programmer also can set the number of samples equal to 5x1024 in the VI. The data acquisition is finished when the number of samples reaches this value. Similarly, the sampling process is started by the index pulse which is the “start trigger”. Note: 1) the sampled data should be put in a buffer. After the sampling process is finished, this data should be saved in a file of LabView; 2) In fact, the data acquired by the sensor are voltage analog input. Questions:1) Could you make a VI for this problem, please? Note: You can use the DAQ ASSISTANT EXPRESS VI or DAQmx TASK NAME CONTROL method.2) How to program the LabView in order to sample data triggered by the rotary encoder (pulse “A”)?3) What should I do to stop the data acquisition at the end of 5 revolutions?4) Could you send examples (VIs) similar to my problem above?5) How can I know if the program (VI) looses an “A” pulse? Is there any kind of error in VI that indicates a miss pulse? In anticipation, thank you very much for any help. My e-mail: [email protected] Bruce

Hello Bruce,
I have a complete solution for this but I cannot give you the VIs because my customer has paied for it and all rights are transfered to him.
What you need are two tasks. One task is the analog in task. You must use the DAQmx Timing.vi and the DAQmx Trigger.vi to set it up as needed. Or you create a task in MAX with this setup. The other task is a counter task just counting the pulses from the z-Index.
Next you need a small state machine with the states:
init, start, wait and stop.
init will initialize and start the tasks
start will read out the z pulse counter and wait for a change from 0 to 1
wait will read out the z pulse counter or the available samples property, when the desired number of z pulses or samples are available read the buffer with DAQmx Read.vi
stop will stop both tasks and clear them.
You will need two additonal counters which you don't have to check for lost A pulses and a external flip-flop electronic. The flip-flop will change it's state with each z pulse and the output will be used for gated counting. With each change of the z pulse counter you need to read out one of the additional counters to check if he had seen the correct number of pulses.

Data acquisition on the basis of time

Hi everyone,
I want to acquire the radial run-out (radial small displacement) of a rotating spindle using a capacitive sensor. To do so I will use the LabView v. 7.1. The PCI-6036E card from National Instruments (NI) will be utilized for data acquisition. The spindle turns at 100 rpm and a rotational incremental encoder is fixed at rear of spindle. This encoder provides an index digital pulse per revolution. This pulse should be used to start and finish the sampling process. I want to sample on the basis of time, by means of sampling rate of the card (Ksamples/s). So, let us suppose that I want to acquire 500 data/rev. The spindle takes 0.6 sec to complete one revolution. Thus, the required sampling rate is Fs = 500 samples/0.6 s = 833 samples/s. So, I should set the VI in LabView so that it samples only 833 data/s. Therefore, I will have to reduce the sampling rate of the analog-input channels in use. For example, let us suppose that the card provides 100 Ks/s when operating in multiple channels. Let us admit that there are 4 analog-input channels in use. So, the scan rate per channel is 25 Ks/s. This is too much for this application. I only need 833 samples/s. So, I should program the VI so that the card provides that required sample rate. As said earlier, I need to start and end the sampling process at the same point. Thus, to do that the index pulse of the encoder will be used. Also, I want to sample during 5 consecutive revolutions of the spindle. So, by means of a loop in VI, I should count the index pulse of encoder until the number of pulses be equal to 5 (= number of revolutions). At this instant, the sampling process should be stopped. Note: 1) the sampled data should be put in a buffer. After the sampling process is finished, this data should be saved in a file of LabView; 2) In fact, the data acquired by the sensor are voltage analog input. Questions:1) Could you make a VI for this problem, please? Note: you can use the DAQ ASSISTANT EXPRESS VI or DAQmx TASK NAME CONTROL method2) What should I do to stop the data acquisition at the end of 5 revolutions using the index pulse of encoder?3) Could you send examples (VIs) similar to my problem above? In anticipation, thank you very much for any help. My e-mail: [email protected]

Data Acquisition for Position Transducer

I just purchased an Analog Position Transducer from SpaceAge Control, and was wondering if anyone had any code to gather the data. I must admit i'm lost when it comes to this, I thought the transducer would come like an instron where you just plug it into the computer. I have a six pronged plug that exits the device. I have a couple TI data acquisition boards at my disposal. I am hoping someone has used a similar product or has some advice. Thank You
Keith

We have lots of code to gather data in all sorts of ways. Building measurement applications is what we do. Since you are lost when it comes to this, you would do well to hire a guide in the form of an Alliance Member company. We do this stuff every day.
Your TI DAQ boards may do the trick, but you would have to show someone the specs for them. Also, you need to think about what kind of speed you require and where you want the position data to go. Table? Plot? Database? A good LabVIEW developer can set you up with some code that does exactly what you want.

Data acquisition from NI PXI 5152 using LabVIEW

Hi,
This might be really stupid question, I am new to LabVIEW and the Digitizer equipment. I was wondering if there are already any labVIEW based application available to read the data from PXI5152. I would be using both channels available and may be trigger. If there is no such application available, what would be port numbers I would be using for data acquisition. But, If I am to develop an acquisition software, I would be looking at every single specification of the equipment. I am assuming the output will be a digitized signal varying with the clock input, since It is used as oscilloscope. When working with labview how would I specify the port to read from and how would my PC recognize the port. I working on a pre-configured system and they won't let me unplug anything to check the configuration. Does NI provides a software to read into the signal fed into the channel and trigger inputs. I have tried looking into the different forum discussion but didn't find any that address my issue. May be it's too simple and stupid. But, it would be a great help if you could point out my misunderstanding.
Thanks in advance.

There are numerous examples. Help>Find Examples> Modular Instruments>Ni-Scope. There is a test panel available in MAX. On the Measurement I/O>NI-Scope palette, are all of the driver functions includeing the NI-Scope Express.
I'm not quite sure I understand your references to 'port's. Once installed into the chassis, it should be listed in MAX. In the functions you will be using, there will be a dropdown menu that you will be able to select the scope resource name.

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.
