Data acquisition from SPCM-AQRH-15 and Nano-ViewTM 200-2/M

I am trying to acquire data from APDs (PerkinElmer, SPCM-AQRH-15) and Nanopositioner (Mad City, Nano-ViewTM 200-2/M). The second equipment has USB 162 or 202 digital interface integrated but I am not sure abut the first one since I am still waiting my order. anyway, I want to control/communicate with both of them using your product, does anyone know what software and hardware I need? thanks.
Solved!

Hello Confuciusl,
I have been looking into the problem
statement that you gave us above and have some questions for you as well as
some answers. I am going to go with the basic understanding that we will be
using LabVIEW to not only communicate with your devices, but also for data
acquisition and analysis.
In reference to your APDs (PerkinElmer,
SPCM-AQRH-15), I have looked at the data sheet for the product located here,
and have determined that the best method of communication with your device
would be to use some type of Counter/Oscilloscope card in a PCI/PXI standard.
This will allow for proper recording of your signal from your Output Terminal.
For more information on cards please refer to this link.
As for the second instrument listed, the
Nano-ViewTM 200 from MadCity, it mentions here that The Nano- View/M™
system includes the Nano-Drive™ controller and is compatible with user written
LabVIEW software. Since we do not have the capability to obtain the product you
are specifically trying to communicate, the best option at the moment would be
to try and contact MadCity and see if they have any specific Instrument Drivers
pre-built for LabVIEW that will allow you to communicate with your device. If
they do not, the next option would be to develop your own by following the
guidelines at the following link.
Thanks again and have a great day!

Triggering a 6024E into data acquisition from start and end number of finite pulse generator from a 6602

My motion control system is driven by a 6602 I wanted to acquire analog current (to a voltage via I/V converter) from a 6024 AI when:
(1) At the start of the pulse generation
(2) Stop at the end of the pulse generation
(3) Read every possible data between and stream it on the harddisk
(4) Option to skip at regular intervals to reduce amount of data accumulation
Anyone have some suggestions? What I did try and attempted was to "loop an AI from a triggered intermediate Analog Input VIs" this is rather erratic!My question for the analog input software are:
(1)Can you trigger an AI to start a continuous acquisition?
(2) How do you do AI from a "start" p
ulse train to "end" pulse train?
(3) How do you manage time for File I/O meanwhile doing (1) and (2) above?

"(1)Can you trigger an AI to start a continuous acquisition?
(2) How do you do AI from a "start" pulse train to "end" pulse train?
(3) How do you manage time for File I/O meanwhile doing (1) and (2) above?"
Answer 1 and 2)
Yes you can, This VI is part of the search examples that ships with LV:
"Continuous Acquisition & Graph Using Digital Triggering and External Scan Clock
Demonstrates how to continuously retrieve data from one or more analog input channels using an external scan clock when a digital start trigger occurs."
Go to Search Examples in the Help/Contents of LV. Then pick I/O Interfaces/Data Acquisition (DAQ)/Analog Input/Triggering an Acquisition/Triggering a Continuous Acquistion.
This VI is appropriate ifs you want to clock the DAQ with some clock (external scan clock) other than the on board clock.
The start trigger required by the DAQ card will be a TTL signal attached to the PFI0/TRIG1 pin of you DAQ card (via whatever signal conditioning you have).
The external clock also needs to be TTL and is attached to the PFI7/STARTSCAN pin.
You tell it which AI channel to use and wire that up appropriately.
All of this stuff is in the context help for the VI.
Answer 3)
You have a misconception of how the acquisition makes its way into a file on the hard disk. You don't really "stream to disk." The VI above will run a buffered acquisition. The DAQ card sets up a buffer that fills with the data continously. When you use the VI you set up how the buffer is configured, you will see controls for buffer size, number of scans to read at a time, etc. The acquisition runs data into the buffer continously and reads from the buffer are a parallel process where chuncks of the buffer are extracted serially. You can end up with a scan backlog where the reads are falling behind the data. Making the buffer bigger helps. All of this is limited by the sampling capability of the DAQ card. 200kSamples/second is for one channel of AI. Divide by 2 for 2 channels. etc.
The short answer is that the VI and DAQ card manage the file I/O for you.
The VI above writes the scan out to the waveform chart on the front panel. You will want to wire that data out from the AI Read Sub VI to a spreadsheet file in tab delimited form or similar.
Look inside the VI block diagram. There is a While loop containing the AI Read. Every time the loop runs (unless you hit STOP), the AI Read plucks the specified # of scans from the buffer (starting from the last unread datum). If you wire the double orange wire from AI Read out of the loop (and set the tunnel for Auto Indexing) the Vi will build another buffer in memory that is a series of AI Reads appended to each other, a sequencial record of the acquisition. Here you put in a Write to Spreadsheet VI. This is in the Functions Pallete, it is the first VI in the File I/O Pallette (icon looks like a 3 1/2 disckette).
There is more to it than this. The spreadsheet Write is 1D or 2D only. By running the array out of the while loop with auto indexing enabled, you create a 3D array. (If you turn off auto indexing you will only get the last array performed by the AI Read.) You will need to create a new array withe the pages of the array placed serially into a 2d array. I don't think I want to get into that. It isn't that bad to do, but you should get some time messing with arrays on your own, then you will see how to do it yourself. One solution is to only run the While loop once with a buffer big enough to hold the whole acquisition, or in other words no loop at all. I don't know how many scans you want. The other thing is by wiring that AI Read out of the loop you are creating an array that must be dynamically resized as the loop runs. Kind of a no no. Better to know what you are acquiring size wise and letting the VI set up buffers and array space that does not need to be changed as the program runs.
Caveat: I am fairly new to this and I could be wrong about the arrays and buffers and system resources stuff. However, I have done essentially what you are trying to do succesfully, but not "continuously." I limited the AI Read to one large read that gets what I need.
"Continously" is usually reserved for screen writes as in the VI above. The computer is not required to continually allocate space for an ever expanding array to be written as a file later. Each time this VI runs the While Loop the data goes to the waveforn chart. Each new AI read overwrites the previous one. Sort of like if you turn the Auto Indexing off. When the VI stops, the waveform chart on screen would show the same data as was written to the spreadsheet.
Feel free to email me directly: [email protected]. I will help as I can.

How to synchronize the data acquisition from both GPIB and DAQ card

I want to begin/stop acquiring the data from GPIB and PCI6024E card into Labview at the same time. Since the acquisition from GPIB is quite slow comparing to the one from DAQ card, I can not put both of them in the same loop structure. Is it possible to synchronize them?
Thank you!

Hi,
I wanted to save data acquired from NI-DAQ (for example, NI 9234) in a file using the DAQ-mx ANSI C Code. The response I got was as follows:-
One way to do it is with TDMS logging. DAQmx comes with functions designed to log to a TDMS file. This is a special file type that is used for collecting data in a logical format. It can be displayed in a TDMS viewer where data is separated into groups and channels. NI-DAQmx provides examples for how to log to TDMS. Look at the TDMS examples in the C:\Users\Public\Documents\National Instruments\NI-DAQ\Examples\DAQmx ANSI C\Analog In\Measure Voltage directory.
However, now I want to know is there a way that using that same C code, can we save the data in a .txt file format (Text File) instead of a TDMS file? We actually want to access that file through MATLAB (that's why we want to save it in text format).
Also on an other note, is there a way we can access & open TDMS files by MATLAB?
Thanks,

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 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.

Sample VI's for data acquisition from SR850

Hi,
I was helped a lot by NI in finding driver for our instrument,SR850. I've
installed its driver and need some sample VI's for its data acquisition. I
am a
beginner in Labview and getting data from SR850 is creating a lot of
trouble
for me at the moment. We have Labview 7.1 installed on our computers in
Linkoping university.
Your help in this regard will be highly appreciated.

Actually i have to plot all of SR850's outputs(X,Y,R) vs. time and save corresponding data on a PC,but i am unable to write its VI. Hope to hear from u soon

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 from a 250N Load cell

Hi ,
I am very new at using the Labview.I am using Labview 6i(PCI 6052E).The load cell(250N) is connected to a pump.The pump has 2 bags.One of them is filled with water and the other is empty.I want to load the bag which is empty from the bag filled with water using the pump.The load cell is connected to the bag which is filled with water.I am trying to aquire a volatge signal continously from a load cell and display it on a chart.
My program has no errors and I am able to run the progam.But it is not aquiring any signal.Could u please help me out.Attached is my code for the same .
-Manasa

Hi Manasa,
Make sure you are handling your errors in your code. You can do this by wiring your error clusters through your VI and then terminate them in a General Error Handler VI. If you are doing this, make sure that your device works in Measurement & Automation Explorer (MAX). Do this by opening a test panel and verifying that you can get a known voltage (like a battery) to read correctly. If you can successfully get a voltage in MAX, try running one of the example programs. You can find them at Help » Find Examples..., then browse to hardware input and output. If you can get an example program that is similar to what you are trying to do to work, try comparing your code to the example.
Please post back if you have any questions. Have a great weekend!

Date Conversion from GMT to Local and Local To GMT considering DST.

Hi,
I have a application which displays the time in GMT across all the screens,and saves in Local/Default TimeZone as application would be deployed in europe and India.I have written a utility which does the conversion.
I just want to know that how to handle the Daylight Saving Time[DST] as we are taking the data from database and converting it to LocalTime Zone.This works fine but what would happen if the sever time is changes due to DST.There would be problem between the object saved before the DST and after DST because we are simply converting stored time to GMT to show on the screen.
Please share if you some solution/suggestions.
Thanks.

A java.util.Date uses a UTC offset with millisecond resolution.
A jdbc driver converts that value into a "correct" value for the target database.And from.
The form that is stored in the database is entirely database dependent. The actual form stored in the database can take many forms.True, but it is highly likely to be an offset from some "epoch" (Progress, for example, uses 00:00:00 1/1/-3714 UTC as I recall, and has 1-second granularity).Yes but as I said the phrasing was odd. A timestamp, by definition, must be an offset of something. Doesn't matter how it is represented. After all the year 2009 is an offset in the Gregorian calander.
However in terms of actual storage the way it is stored is unlikely to be similar to what Java does. As examples neither Oracle nor MS SQL Server uses a single numeric offset.
It might not even have a concept of timezone.Again true, although I've yet to come across one; and since OP is only concerned about the timezone in Java I'm not quite sure how relevant that is.
Relevant in terms of the description in terms of what java does, what the database does and how it gets from java to the database.
I would also expect any JDBC driver that cannot translate to or from a Java date correctly to document the fact in 60-point bold type, since it's a violation of the implied contract of ResultSet.getDate().Except that depends on your definition of "correct".
Examples of that
- Oracle doesn't have millisecond resolution at all in its common format.
- MS SQL Server doesn't have the same resolution as java, instead there is an odd resolution (one three-hundredth of a second).
- MS SQL Server doesn't have timezones, so if you don't take care and your data crosses timezones the timestamp will be different.
The drivers will not warn you of things like that. At least not that I have seen.
Format for Oracle.

Name of the data file from a user prompt and a constant

I have following situation:
The event is single shot, each shot the two DAC card acquires 8 channel data (total 16 channels) and the user has to decide if we want to save the data in a file.
Once we decide that we want to save the data, the program should prompt for a file name. The inpu will be some dgit corresponding to an event number let us say xxxxx.
The program should create a file name 133Axxxxx.dat (or any other extension). 133A and 133B will be my two devices dev1 and dev2 respectively.
Can some one please help, how do we do this? The data from each card should go in a different file. The file name should be 133Axxxxx.dat and 133Bxxxxx.dat (let us say)

I think this is what you want. If not it should be close enough so you can modify easily.

Data fetch from table without Refresh and without using tab key.

hi Friends,
I have a problem i want to extract data from table without Refresh into text field without using Tab key. when i'll enter any value in a text field then corressponding value should come in to corressponding textfield without using Tab Key.
eg. when i enter emp_id 101 in a text field then the first_name and last_name ,adress should come in to corressponding text fields without refresh and without using Tab key.
How Can I do this.
Thanks
Manoj

Hi Manoj,
I assume that this is similar to: Data fetch without Refresh rather than Re: Value of one textfield should come into another textfield Without Using TAB ?
If so, the only change you need to make on the first one is to use "onkeyup" instead of "onchange" in the item's "HTML Form Element Attributes" setting.
Note, however, that the user must move away from the item at some point (for example, to click a button), so the onchange will be triggered anyway.

Data extraction from Profit center accounting and load to BCS

We need to extract data from profit center accounting in SAP R/3 and then we will have to load the same to BCS ( Business consolidation) module as file upload.
Can anyone please explain me the steps involved in extracting the data from Profit center accounting.
Advance thanks.

One way is to view GLPCT table and summarize in Excel as needed. This can subsequently be saved as CSV to fit the flexible file upload configuration.
Another alternative is to extract the table to a basic infocube and use this a the source data basis for the load from data stream data collection method.
Good luck.
