How can i write a pattern to a output port of NI PCI 6503 with Traditional NI DAQ 7.0 and Visual Basic 6.0?

Hello, i'm using a NI PCI-6503 (with CB50LP accesory) to write digital patterns to one of the output ports. Can i do it directly from NIDAQ7.0?
I know some Visual Basic 6.0 functions to configure a par as output and to write a pattern to a port, but i don't know how run it.
I've read some examples from "Help" (C:\Program Files\National Instruments\NI-DAQ\Examples\VBasic\Do) but I can't measuring TTL levels on my CB50LP accesory.
Thanks!!

Hello,
What is your buffer size ? The buffer should be 0 or greater than 2. You can get this error if your buffer size is equal to 1.

How can I write bits through the COM1 serial port?

I'm trying to write bits through the serial port COM1.
Labview "Write VI" only writes everything in string. It seems. How can I write bit by bit through COM1?
Thank you,
Van

Serial transmission (COM port) protocol requires sending a group of bits at one time. You cannot just send one bit. Standard COM port settings must be either 7 or 8 data bits, 1 or 2 stop bits, etc... You have to group your bits 7 or 8 at a time. You could probably send a 0 byte or a 1 byte. This would be like sending 0000 0000 for a low bit and 0000 0001 for a high bit. Your receiving end would have to know how to interpret what you are sending if you choose this method. Of course you have to convert your byte into a string before sending to COM port. Wire a U8 data type to a Build Array input. Then wire the array output to a Byte Array to String input. The output of this function will be the character representation of your byte suitable for sending acr
oss a serial port.

How can i write a vi in using parallel port for digital inputs

Dear all,
i am a beginner user of LabVIEW and i want to write a vi in using parallel port for digital I/O. After reading the article "Using the Parallel Port in LabVIEW
" and download the parallel.zip, i know how to write the vi for output, but i still don't know how to write the input one.i've try to use a Inport.vi to test, but nothing change when i set pin2-9 to high. (my computer:win2K & LabVIEW 6.1)
Can anybody teach me how to write it?
Can anyone write the vi for me too?
Thanks all!
p.s.i've already install the "accessHW.exe"

Are you using VISA or the accessHW VIs? You may need to goto the bios and set the parallel port to run in spp mode or standard mode. This is the simpliest configuration and where you should start.
As far as writing the VI goes, just copy the diagram out of the tutorial you mentioned.

How can I write a program that compiles without warnings?

I tried the following with the 1.5 beta-compiler (build 28; I think):
class Y {
     public static final class Pair<X,Y> {
       private X fst;
       private Y snd;
       public Pair(X fst, Y snd) {this.fst=fst; this.snd=snd;}
       public X getFirst() { return fst; }
       public Y getSecond() { return snd; }
       public String toString() { return "("+fst+","+snd+")"; }
public static void main(String... args) {
     Pair[] pairArr = new Pair[10];              // supposed to be an array of Pair<Integer,Integer>
     for (int i=0; i<pairArr.length; i++)
         pairArr[i] = new Pair<Integer,Integer>(i,i);
     for (int i=0; i<pairArr.length; i++) {
         Pair<Integer,Integer> p = pairArr; // unchecked warning
     System.out.println(p);
     Integer first = p.getFirst();
     Integer second = p.getSecond();
// ... more stuff ...
It turns out that I get an unchecked warning when I extract an element from the array of pairs. Okay, that's fine. How can I avoid the warning? I had expected that an explicit cast would help.
Pair<Integer,Integer> p = (Pair<Integer,Integer> )pairArr;
With a cast I'm telling the compiler: "I _know_ what I'm doing; please trust me." But the compiler still issues a warning.
How can I write a warning-free program in this case? The only thing I can think of, is not using the parameterized type Pair in its parameterized form. But it's not the idea of Java Generics that I refrain from using parameterized types. What am I missing?

It turns out that I get an unchecked warning when I
extract an element from the array of pairs. Okay,
that's fine. How can I avoid the warning? I had
expected that an explicit cast would help.
Pair<Integer,Integer> p = (Pair<Integer,Integer>
)pairArr;
With a cast I'm telling the compiler: "I _know_ what
I'm doing; please trust me." But the compiler still
issues a warning. Yes, but at least you were able to change the warning from "unchecked assignment" to "unchecked cast" which is a little shorter ;-)
Seriously , since arrays of generic types are disallowed, there is probably no way to get rid of these warnings - which makes a strong point for eliminating "unchecked" warnings altogether (see the other thread "selectively suppressing compiler warnings")

How can I Write a sine wave in an Access-file?

I measure a sine wave in LabView 6i. How can I write the datas automatically to an Acces-file, at the same time?
In my program, I managed it with Execute SQL.vi, I change a number in a SQL statement(String) -> after this I push start and then it writes the statement in the Access-file.
The problem is, it writes only one data per measurement in the file. How can I write all datas in the Access-file and measure the wave at the same time?
Thanks for help!

On the waveform palette, you will find a "to components" vi that you can break out the array of the waveform. You can then, using a for loop write all of the values from the waveform.
Better yet, there are examples in the database toolkit manual on pages 3-13 to 3-15 that deal with reading arrays (and even has a waveform example).
Good luck!

dont use NE in the select statements, it may effect performance also. Instead use if statements inside
loops.
loop at t_caufv.
read table it_chrd............
if t_caufv-objnr ne it_chrd-objnr.
read table it_jest..........
   if   if t_caufv-objnr ne it_jest-objnr.
    (proceed further).
   endif.
endif.
endloop.
hope this helps.

How can I write into a table cell (row, column are given) in a databae?

How can I write into a table cell (row, column are given) in a database using LabVIEW Database Toolkit? I am using Ms Access. Suppose I have three columns in a table, I write 1st row of 1st column, then 1st row of 3rd column. The problem I am having is after writing the 1st row 1st column, the reference goes to second row and if I write into 3rd column, it goes to 2nd row 3rd column. Any suggestion?
Solved!
Go to Solution.

When you do a SQL INSERT command, you create a new row. If you want to change an existing row, you have to use the UPDATE command (i.e. UPDATE tablename SET column = value WHERE some_column=some_value). The some_column could be the unique ID of each row, a date/time, etc.
I have no idea what function to use in the toolkit to execute a SQL command since I don't use the toolkit. I also don't understand why you just don't do a single INSERT. It would be much faster.

Hey Atrina,
The actual data stored on disk is just the raw data (that is, a byte per sample in your case). It's really just a matter of how that data is being represented in LabVIEW whenever you read back the TDMS file.
I'm not sure if there is a better way to do this, but here is a way to accomplish what you're wanting:
Read back the TDMS file as a digital waveform. Then there's a conversion function in LabVIEW called DWDT Digital to Binary. This function will convert that set of digital channels into the "port format" that you're wanting. I've attached an example of what I mean.
Note: When looking at this VI, there are a few things that the downgrade process did to the VI that I would not recommend for these TDMS files. It added a 1.0 constant on the TDMS Open function, and it set "disable buffering" on the TDMS Open function to false; you can get rid of both of those constants.

Drive Partition and Format
1.Open Disk Utility in your Utilities folder.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed.
4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
5. Set the format type to Mac OS Extended (Journaled.) Click on the Security button, check the button for Zero Data and click on OK to return to the Erase window.
6. Click on the Erase button. The format process can take up to several hours depending upon the drive size.
Steps 4-6 are optional but should be used on a drive that has never been formatted before, if the format type is not Mac OS Extended, if the partition scheme has been changed, or if a different operating system (not OS X) has been installed on the drive.

How can I write to an OPC Server?

Hello!
I was busy a few days with LabVIEW 8 to finish a special task, but now I've got problems to solve the following problem:
I have an OPC connection between a frequency converter and LabVIEW 8. With the example vi's I get the data out of the OPC Server (revolutions per minute).
So I can read data out of the OPC Server, but how can I write? I want to write several voltage values to the OPC Server that the frequency converter gets the required revolutions per minute.
Have you got any ideas? Are there existing example vi's to write data to an OPC Server?
Best regards and Thanks in advance!

So here it is - a little bit modified, but you should get the idea out of it.
If you have questions, I'll try to answer them .

By default, OS X (and near all operating systems different than Windows) can't write in NTFS drives because of a Microsoft limitation.
To be able to write in NTFS drives, you have to use a third-party application. There are a lot, but the most recommended is Paragon NTFS, although it's a paid application. If you want a free app, try this > http://osxfuse.github.com
