Viewing more values on Graph from DAQ Card

Hello,
I am acquiring a Signal using DAQ Card, the problem is that i can view only few values on the Waveform Graph. Kindly guide me if i want to view more points on the waveform graph, what should i do in my programming window.
Regards

Hi Abuzar,
your VI is just an expressVI and a graph - nearly to nothing…
- Why do you set the DAQAssistent to "limited number of samples", when you want to have a continuous measurement?
- Did you look at the example VIs coming with LabVIEW? Those that explain DAQmx functions?
- A graph only displays the data in the wire you feed to. When you want to display more data you need to collect it. When you really want to stick with expressVIs then you could use the one, which allows appending signals…
- Learn to use shift registers!

Looking for examples of VI with two or more inputs for the 1200 daq-card ( PCMCIA )

Thank you , if you can help me by sending VI examples for the 1200 daq-card
, with 2 or mores inputs

You can find several examples that will work with the DAQCard-1200 at zone.ni.com/libraries/.
Then look under Data Acquisition. There are also examples that ship with
LV and NIDAQ. Look in ...\Labview\examples\daq\anlogin\.

Is selecting from a view more efficient than selecting from multiple tables

Hi heres the problem
Lets say i created a view from 2 tables (person and info). both have a ID column
create view table_view (age,name,status,id) as
select a.age, a.name, b.status, b.id
from person a, info.b
where a.id=b.idif i want to select a given range of values from these 2 tables which of the following queries would be more effective.
select a.age, a.name, b.status, b.id
from person a, info.b
where a.id=b.id
and a.id <1000
select age, name, status, id
from table_view
where id <1000

Bear in mind that this concept of views storing the SQL text is something relative to Oracle databases and not necessarily other RDBMS products. For example, Ingres databases create "views" as tables of data on the database and therefore there is a difference between selecting from the view and selecting from the base tables.
Oracle also has "materialized views" which differ from normal "views" because they are actually created, effectively, as tables of data and will not use the indexes of the base tables.
In Oracle, you cannot create indexes against "views" but you can create indexes against "materialized views".

Viewing more than 9 Forms from the Window Menu Item

Hi,
I would like to know if you can list more than 9 Forms at one time from the Windows Menu Item before you have to select the MORE WINDOWS option to display the entire list of currently opened forms.
Can this be set in the .mmb or some config file?
It would be nice to have a list of about 12 Forms to choose from at one time before selecting the MORE WINDOWS option.
Christina.

Hi Frank,
The Forms version our system uses is Oracle Forms 6i.
A user would like to know if this scenario is possible during runtime.
However, I would like to know what modifications can I make during design time to make this possible.
Thanks.
Christina.

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,

Hi, i'm new in lab view. i'm using 3'rd party daq card to get data using labview

i'm still green in this field. can anybody help me on how to get various data from daq card(not an ni brand) using my labview programming. i use labview 6 and i don't know how to get the data so i can display it in my programming. i used Pcl 1800 and pcl 836 card of advantech brand.

Greetings,
Below is a link to a KnowledgeBase, which discusses your options:
http://pong.ni.com/public.nsf/websearch/F3009806E2AE416E8525645D0076B962?OpenDocument
It appears that Advantech has a LabVIEW driver available. Below is a link to information about the driver on their Web Site. I would suggest trying this option, as opposed to using the Call Library Function with Advantech's driver DLLs:

How to read the gain list of a DAQ card from labview?

Hi,
Its known that you can set the gain of an ADC of a DAQ card by setting the high and low values.
Different cards have got different signal ranges corresponding to different gains.
My question is ... Is it possible to read the gain list of a DAQ card from labview?
It is definitely possible to read the signal ranges available for the device. It would be very helpful if some one can tell me the method to read the gains corresponding to the signal ranges.
(Even the device specification provides only the signal range but not the gain corrsponding to it )
Thanks
Message Edited by Vsh on 04-08-2008 03:50 AM

Hi Vsh,
It appears that you have found the gains applied for the various ranges (I assume from the user manuals). So if I understand your question correctly, you are looking to poll the card for the current gain (or the various gains available)
Because DAQmx selects this for you (unlike Traditional DAQ), there is not a way to poll directly. If you want, you could poll the min/max values and then use this to figure out the range setting (and thus the gain).
Please refer to this post, it gives more information about the gains/ranges in general.
I would suggest putting in a product suggestion if you would like this feature. Those go into the decision making process for our R&D team, meaning they actually do look at them. If you wish, I can submit a suggestion internally was well for you, that way your suggestion gets 2x the exposure. Let me know if you want me to do this.

How to acquire data from 2 chs of the same DAQ card at different sampling rate

I am using single DAQ card (either 6013 or 6014) in my system i want to acquire data from 2 (or more) channels with following requirements
1. sampling rate of each channel should be independant of each other (say one is 20 Hz and other is 15 kHz)
2. data from all the channels should be acquired simultaneously.
3. coding must be done using DAQmx VIs
I have tried out following things
1. I created separate task for each channel: i found out that two tasks can not run simultaneously even though the channels are different
2. I tried out single task with two channels included in it. and i used 'channels to Read' property to determine from which ch. i want to acquire data: this method works fine if the sampling rates are same. but if i change the sampling rate of one channel it gets reflected in other channels as well.
can somebody help me out to solve this problem.
i will appreciate if somebody can post the sample code as my deadline is approaching

How to display the binary code received from a DAQ Card

Hi everybody,
My LabVIEW application receives data from a NI-6036E DAQ Card. Is there a possibility to see the binary code sent by the card? Because all what I found show only the analog value.
Thanks for your help

Assuming that you are using DAQmx, simply select the polymorphic selector of the DAQmx Read and do a Analog>Unscaled and then pick the type of integer array you want. If you are using the DAQ Assistant, I don't think you can select unscaled for that so you could convert the assistant to a VI and modify that (right click on it and select Open Front Panel). If you are not using DAQmx, please provide the name of the function you are using.

Index array is not getting new values from DAQ

I am measuring force values with my DAQ card and these values are always changing. However, in my programming something is not working right with the way I have things set up. After my DAQ I have a "Convert to Dynamic Data" and after that I have an "Index Array". When the program is executing and I turn on the highlight option I do not get changing force values after the "Convert to Dynamic Data" and therefore no changing force values enter my "Index Array". Whaterever the first value is that gets passed to the "Convert to Dynamic Data" is the only value that I get for the remainder of the program. I tried plugging in an indicator between the DAQ and the "Convert to Dynamic Data" and it did show varying values. Please help with my program. I have tried messing with the properties of the "Convert to Dynamic Data" and nothing has worked. I am stuck and cannot see how to fix this problem. I have attached my program as it is currently put together.
Thank You In Advance,
Gabe.

Please know that the best option is to review the concepts discussed to further understand programming in LabVIEW. Perhaps you could take a look through ni.com/gettingstarted and ni.com/lv101 to have a look at some of the online help materials. I have included a VI snippet of the while loop containing the changes. Further, the code you attached contains a lot of customer controls and VIs, which are not common to all LabVIEW users. It is a best practice to only attach the code of value to the question/post, and to have the most simplified version of the problem.

Advanced table:not able to view more than 10 rows when called from workflow

Hi everyone,
I'm calling a page that contains advanced table and its controller class from two places.
First one is from a inquiry form, when this page is called it works fine. when there are more than 10 rows, first 10 are shown on page render and when we click on Next link, other rows are shown. This is becuase I have given the records displayed property on adavanced table = 10. I'm fine till here.
Second one is I'm calling this page again from a workflow notificaiton. There is a link called view more details on the workflow notification , click of this link will open the page with 10 records displayed. But when user tries to click on Next it doesn't work. It just doesn't refresh.
Its very wierd,. not able to understand what could be wrong when calling from wf notificiton. Its the same page and conroller code used in both the places.
Please help me!!
Thanks
Sunny

Thanks for your response Kristofer. You are correct, there was a difference in the parameters and the issue is resolved now.

How do i generate the TTL pulse from PCI 6024E DAQ card

Hi, I'm trying to write a program which generates a single TTL pulse when it is run. My goal is to generate the pulse, send it to the output channel of my PCI 6024E DAQ card, and then use a BNC cable, to display the signal on the oscilloscope. I have written the code and I think it appears fine but when I try to view the signal on the scope I am unable to see the pulse. I have tried slowing down the sweep on the scope and have adjusted the voltage and time scales but have not seen any response. After examing my DAQ card, I noticed that none of the PFI/TRIG terminals on the card are wired; the output channel connects to terminals for DAC0OUT and Ground. I'm wondering if this pin needs to be wired in orde
r to generate the pulse since PFI0/TRIG1 is the start trigger terminal. Any help would be appreciated. Thanks.

Fetching more than one row from a table after selecting one value from the dropdown

Hi Experts,
How can we fetch more than one row from a table after selecting one value from the dropdown.
The scenario is that I have some entries in the dropdown like below
A               B               C
11256          VID          911256
11256          VID          811256
11256          SONY      11256
The 'B' values are there in the dropdown. I have removed the duplicate entries from the dropdown so now the dropdownlist has only two values.for eg- 'VID' and'SONY'. So now, after selecting 'VID' from the dropdown I should get all the 'C' values. After this the "C' values are to be passed to other methods to fetch some data from other tables.
Request your help on this.
Thanks,
Preeetam Narkhede.

Hi Preetam!
I hope I understand your request proberly, since this is more about Java and less about WebDynpro, but if I'm wrong, just follow up on this.
Supposed you have some collection of your original table data stored in variable "origin". Populate a Hashtable using the values from column "B" (let's assume it's Strings) as keys and an ArrayList of whatever "C" is (let's assume String instances, too) as value (there's a lot of ways to iterate over whatever your datasource is, and since we do not know what your datasource is, maybe you'll have to follow another approach to get b and c vaues,but the principle should remain the same):
// Declare a private variable for your Data at the appropriate place in your code
private Hashtable temp = new Hashtable<String, ArrayList<String>>();
// Then, in the method you use to retrieve backend data and populate the dropdown,
// populate the Hashtable, too
Iterator<TableData> a = origin.iterator();
while (a.hasNext()) {
     TableData current = a.next();
     String b = current.getB();
     String c = current.getC();
     ArrayList<String> values = this.temp.get(b);
     if (values == null) {
          values = new ArrayList<String>();
     values.add(c);
     this.temp.put(b, values);
So after this, you'll have a Hashtable with the B values als keys and collections of C values of this particular B as value:
VID --> (911256, 811256)
SONY --> (11256)
Use
temp.keySet()
to populate your dropdown.
After the user selects an entry from the dropdown (let's say stored in variable selectedB), you will be able to retrieve the collection of c's from your Hashtable
// In the metod you handle the selection event with, get the c value collection
//and use it to select from your other table
ArrayList<String> selectedCs = this.temp.get(selectedB);
// now iterate over the selectedCs items and use each of these
//to continue retrieving whatever data you need...
for (String oneC : selectedCs) {
     // Select Data from backend using oneC in the where-Clause or whatever...
Hope that helps

Hi Ranendra,
For basic understanding of Dashboards and Models you can use standard Templates or samples which ll come along with dashboard designer(Formly Xcelsius) installation.
For path File-->Templates(or Samples).
Under Templates you ll have different categories and for each you ll find the dashboard Templates.
