Use one counter to trigger another

Hello
I would like to use ctr0 as a trigger source for ctr1, i.e. ctr1 should begin to run every time ctr0 produces a rising edge. This works good as long as I produce only one puls with ctr0, however I Iike to retrigger ctr1.
The code I am using yet is attached, but it works only for a single puls of ctr0.
Does anybody know how to implement this in LabVIEW?
(used hardware board: PCI-6025E)

Hi MG83,
I will try to respond to your question:
I have done some minor modifications. First I have changed from frequency / duty cycle back to high time / low time control.
Further
I I tried to change the upper counter (actually counter 0) from the
"continous samples" mode to the "finite samples" mode, because I want
to produce only a finite number of pulses (e.g. 10), but then I get
exactly the same error as yesterday.
If you let the configuration like I made with your card number, you will not receive any error message.
If you want to generate 10 Pulses you must start the task again after each generation.
If you receive the same error as yesterday, you don't configure the counters correctly.
First try to generate pulses on the counter0 without counter1 and after that try to do the both simultaneously...
PS: Take care that you don't have the test panel open at the same time.
Is it possible that I simply do not have enough
hardware resources for this purpose on the PCI-6025E-Board? Or where is
the problem?
No there is here no problem, I try with a 6025 and it work exactly as on my 6040...
Another question: You use the "is task done"-VI
for the lower counter. However this counter is cofigured to be
retriggerable, so I wonder, if the "is task done"-VI can ever return
TRUE? Or in other words: How should this task know, if there are no
further trigger events so that it is done?
It's te same method as in the example...You must hold the task open...and you use this function to chack if an error occure, if you don't use function in the loop, you don't check the errors and don't have informations...
Try first to use my example and if the a problem come, post your question with a screen shot of the error that you receive.
Please take care that the counter are right configured and that you did not open tasks on the same ressources...
Regards.

Using one counter with FiniteSamps and another with ContSamps

I am trying to use 2 counters on the USB-6229 (or USB-6259), where one counter is set up for FiniteSamps and another for ContSamps. I have the following MeasurementStudio code:
ErrChk DAQmxCreateCOPulseChanTicks(hCnt0, "Dev1/ctr0", "", "20MHzTimebase", DAQmx_Val_Low, 0, 400, 400);
ErrChk DAQmxCfgImplicitTiming(hCnt0, DAQmx_Val_FiniteSamps, 100);
ErrChk DAQmxStartTask(hCnt0);
ErrChk DAQmxCreateCOPulseChanTicks(hCnt1, "Dev1/ctr1", "", "20MHzTimebase", DAQmx_Val_Low, 0, 400, 400);
ErrChk DAQmxCfgImplicitTiming(hCnt1, DAQmx_Val_ContSamps, 2);
ErrChk DAQmxStartTask(hCnt1);
When I run it, I get a run-error 50103 "The specified resource is reserved". If I change the FiniteSamps to ContSamps on the first counter, everything works fine.
If I use only one counter with FiniteSamps, everything also works fine.
Is this a bug in DAQmx or the dual counter use on M-series devices is limited to ContSamps?
Vic
Solved!
Go to Solution.

Hi Vic,
This is actually expected on an M Series device. Here's a timing diagram from the M Series User Manual that might make this a bit more clear:
The device actually uses one counter to gate the other so the result is a finite pulse generation. If you can provide the gate from another source, you may configure a continuous pulse generation on both counters and gate them (DAQmx calls this a "Pause Trigger") from this external signal.
You might also want to look into using Correlated Digital I/O to generate multiple finite pulses (up to 32 lines on your 6229 and 6259). You could use one of the counters to generate a timebase for the digital lines, and build the waveform accordingly.
One thing to note is that our new X Series boards can generate a finite pulse generation on a "single" counter (there is actually a paired internal counter that allows for this). There are four user-accessible counters on X Series devices, meaning you could generate four finite pulse trains.

How to use one query results in another query

hi,
in help.sap I have founded that using variable type replacement path I can use one query results in another query. It is wrote there that I have to choose query name results I want to get in variable definition but I do not know where.
How I can do this?
Result I want to get is:
In one query I have material prices in another material quantities. I want to calculate inventory value (price * quantity). Moreover prices are on plant level, quantities on storage type level. Plant is atribute of storage type.
Can I do this?

Can source and gate used to measure 2 signals using one counter?

I have one PCI 6602 card to measure measure the frequency. PCI 6602 has 10 channels, in which channel 5 and 10 doesn't have 'source' terminal.
We have to measure frequency from 16 signals using one PCI 6602.
From channel 1 to 4 and 6 to 9, we have 8 'Gate' and 8 'Source' terminals.
We have connected 16 signals to these 16 terminals.
At any given point of the time we want to measure either 'Gate' signals(8) or 'Source' signals(8).
Can any provide any guidance to make a program in labview to measure frequency (period) as per above given points?
Regards
Vijay

Hello Vijay,
It takes one counter for each digital frequency you want to measure and the PCI-6602 has 8 counters total. This means that the maximum number of digital frequencies you can measure is 8. If you want to measure 16 frequencies you'll need 16 counters.
Single counter frequency measurements are made by comparing the board's time base (80 MHz) to an external frequency. The board counts the number of time base periods that occur during one period of your incoming frequency. When you configure the board to take a single counter frequency measurement the card routes the time base to the source of the counter and then you connect the frequency you want to measure to the gate of the counter.
Here are a couple of articles that explain how these measurements are taken and calculated. (The second article is on period measurements so for frequency measurements you measure period and take the inverse):
Making Accurate Frequency Measurements
Period Measurements with a Counter
There are example programs available in the LabVIEW example finder. You can locate these by going to Help>> Find Examples... The examples you want is: Hardware Input and Output>> DAQmx>> Counter Measurements>> Digital Frequency>> Measure Digital Frequency- Low Freq 1 Ctr.vi.
I hope this explains how counters work and why you need one counter per measurement.
Cheers,
Brooks

How to use one hash table inside another hash table

Hi everyone,
Any example of hash table inside another hash table.
Can one here help me how to write one hash table inside another with repeating keys for the first hash table.
Thanks,
kanty.

Do you mean you want the 'value' entries in a hash table to themselves be hash tables? Easy but this often indicates a design flaw.
Hashtable<String,<Hashtable<String,Value>> fred = new Hashtable<String,<Hashtable<String,Value>> ();But what do you mean by "with repeating keys for the first hash table"?
Edited by: sabre150 on Jul 2, 2010 10:11 PM
Looks like you have already handled the declaration side in your other thread. I suspect you should be writing your own beans that hold the information and these beans would then be stored in a Map. The problem I have is that your description is too vague so I can't be certain.

Can I use one document to open another?

I am assuming this is a scripting problem though I am not a scripter myself.
Basically the situation is this: I have a number of Appleworks documents each of which contains many thumbnails of images, and each thumbnail is also a hotlink to a url for the web page which hosts the full size image. I would be perfectly satisfied with this setup except that the Appleworks icon in Finder is total rubbish, worse even than a Classic icon. I cannot use the Finder (column view) to see from the icon which document it is.
To get around this, I have also saved the same documents in Photoshop as small jpegs, which give a beautiful, sharp, clear, LARGE icon image in Finder.
The problem is that I now have PAIRS of documents, one Appleworks and one Photoshop, a total of more than 50 pairs in a folder. What I want to do is to use the jpeg solely to identify the document in Finder, then when I double-click on it, the Appleworks document opens. Can I link document files together so that if I double-click one, the other opens?
I believe the clue may lie in aliases? I have created an alias of one of the jpegs, and its icon is every bit as good as the original document. Can I now get the alias to point to another document, in this case its paired Appleworks document?

Hello christopher,
Well, you may give this another try, though it's a little out of the scope of your original question. (Technically, custom icon and preview are two things ; ))
The following script will try to get preview image , i.e. pair of 'PICT' and 'pnot' resources, from Photoshop JPEG file and put it in the corresponding AppleWorks 6 file's resource.
If recent Photoshop JPEG file still stores the preview image in that fashion, this script should help. Otherwise, it would do nothing, hopefully. (Try the script on a test folder first.)
To run this script, you need to install Satimage.osax that is free scripting additions made and distributed by Satimage-software, France. See script's comment for more details.

Using one Cursor data in anothe rcursor

Hi all,
I have a requirement of processing the following.
I have to select the rows for which few selected attributes are null. Then I need to take one more attribute for these rows and check that if the value of that row exists for any other row except this one. If that id exists for another row ,then I have to update two fields concatenate with the value.
Ex:- suppose I have 3 rows for which all the three attributes are null. I have a value say CCN_ID which I have to check if that exists for any other row other than this. That means the CCN_IFD of these 3 rows should be checked for existence in any other rows in the same table. If any of the CCN_ID of these 3 rows exists, then I need to update that row with attribute (Sayx)CCN_ID concatenated by the CCN_ID.
I wrote the following query to accomplish this.
select CCN_ID from TEMP_ARTICLE_TABLE where ARTICLE_NO is null and COLOR_BOTTOM is NULL and COLOR_TOP is NULL and CCN_ID IN
(SELECT DISTINCT CCN_ID from TEMP_ARTICLE_TABLE where CCN_ID in(select CCN_ID from TEMP_ARTICLE_TABLE where ARTICLE_NO is null and COLOR_BOTTOM is NULL and COLOR_TOP is NULL)
and rowId not in(select rowId from TEMP_ARTICLE_TABLE where ARTICLE_NO is null and COLOR_BOTTOM is NULL and COLOR_TOP is NULL));
But I was requested to write a Stored Procedure to do this. So, I am thinking of creating two cursors in which the first cursor's data is used in second one as follows.I am receiving compiling errors as follows while compiling t he code.Am I doing in the best possible approach? Is there any other better approach to accomplish my requirement?
SP Code:-
CREATE OR REPLACE PROCEDURE SP_ARTICLEDATA_CLEANING IS
CURSOR Cur_CCNID is
SELECT rowId,CCN_ID FROM TEMP_ARTICLE_TABLE WHERE ARTICLE_NO is null AND COLOR_TOP IS NULL AND COLOR_BOTTOM IS NULL;
CURSOR Cur_ModCCNID IS
SELECT DISTINCT CCN_ID FROM TEMP_ARTICLE_TABLE WHERE CCNID IN(Cur_CCNID.CCN_ID) AND rowId NOT IN(Cur_CCNID.rowId);
BEGIN
FOR rec in Cur_CCNID
LOOP
BEGIN
UPDATE TEMP_ARTICLE_TABLE SET COLOR_TOP='FIX_'||rec.CCN_ID WHERE CCN_ID=rec.CCN_ID and rowId in(cur_CCNID.rowId);
END;
END LOOP;
END;
Errors:-
[Error] PLS-00225 (5: 102): PLS-00225: subprogram or cursor 'CUR_CCNID' reference is out of scope
[Error] ORA-00904 (5: 102): PL/SQL: ORA-00904: "CUR_CCNID"."ROWID": invalid identifier,

Please guide me if there is abetter way or how to correct these errors.
Thanks,
Pavan.

The basic answer to your problem is use SQL. A single SQL statement can very likely do the entire operation. There is no need for using row by row (called slow by slow) processing in PL/SQL.
PL/SQL is inferior when it comes to crunching database data. That is the territory of the very powerful and very flexible SQL language. Or simply put: Maximise SQL. Minimise PL/SQL.*
As for cursors - a cursor is the compiled and executable for a source code program (e.g. SQL statement). It is not a result set. This cursor/program outputs data. It even takes parameters in the form of bind variables. Which means the same cursor (executable) can be used repeatedly, even by different sessions, and executed with different parameters (called bind variables).
Want to insert 10 million rows? Single SQL cursor (executable program). Called 10 million times. Each time with different parameters (bind variables). Via 10,000 different application sessions. At the same time.
So a cursor calling a cursor - not really a sensible approach. Cannot be done the way you want in your code. Is used for unique processing requirements like running PL/SQL in parallel using pipe line table functions.
Bottom line - whoever told you to write a stored proc to do this, is wrong. The correct solution is writing SQL to perform the processing and update you need. That SQL can then be placed inside PL/SQL in order to manage the execution of that SQL cursor and deal with validation of input parameters, handling errors, code instrumentation and so on.

How to use one button to drive another button click

I'm trying to figure out a way to fix a bug in my application. The simple fix would be to have a single button that drives a MouseCLICK event on another button everytime the PlayBar in my application reaches the end of the screen and returns to its origin.
How would I achieve this? I have made a lot of headway since I last posted a question in the ActionScript 3 forum, which was only yesterday evening.
Thanks in advance,
markerline

The application is an audio application. It is like a drum machine sort of.
Currently there is a grid and whenever active cells get hitTest'ed by the PlayBar they become deactivated, the PlayBar returns to the origin, and when you relaunch the Play functionality the deactivated cells no longer play a sound.
I have a button which reactivates the sounds.
I also have a button which has a bug in it that loops the sounds.
To go around the looper button that has a bug in it I would like to use a Button "Z" which automatically clicks the "reactivate the sounds" button every time the PlayBar returns to the origin and the PlayBar will then continue to play and return to the origin in a looping fashion. If the Button Z is in an active state this looping will continue. To stop looping, click the Button Z until it is no longer in an active state and the PlayBar will then remain at the origin.

Using one computer to control another - wirelessly

I think this is a simple question but I have no idea how to start.
I want to use my iBook to tell my iMac - both on the same wireless network - to open iTunes and which songs to play. Sounds like the sort of thing I should be able to do but, like I already said, no idea where to start.
Can anyone put me on the right track?

This can be done by remote desktop connection / VNC. However, it can also be done via AppleScript if you like as well.
Apple Remote Desktop is a separate product, however, you can enable in the Sharing preferences to allow remote desktop connections and connect via freeware apps like Chicken of the VNC. This sill allow you to view and interact with the desktop of one machine from the other.
In the case of AppleScript, you can enable receiving Apple Remote Events on the iMac and then control iTunes (or whatever) as you would were it locally. For example:
tell application iTunes of machine "eppc://username:[email protected]"
play playlist "80's Hair Bands"
end tell

Use one hard drive in another MacBook

Got a new MacBook Pro and want to take my SSD drive out of my old one and use it as the boot drive in the new one. Can I just switch them and no problem or are there going to be issues?
If there are issues can I clone my SSD hard drive to me new one, erase the SSD, then clone it back as the boot drive?
Thanks.

Get the enclosure as Ralph suggests.
Insert the SSD in the enclosure and attach it to the new MBP via USB.
Open Disk Utility>Erase and select Mac OS Extended (Journaled) and click on the Erase button.
Then use Disk Utility>Restore. Select the HDD in the MBP as the 'Source' and the SSD as the 'Destination' and click on the Restore button.
Swap the two drives and the new MBP with the SSD should boot.
Ciao.

New to LABVIEW. How can I use one analog channel to trigger acquisiton of a signal on another analog channel?

I am new to using Labview and have been tasked to write data acqusition program for my company. We are attempting to log 6 machines, each with their own asynchronous trigger (I can't use one trigger for all 6 machines). I have the idea to use (for example) ai0 for the measurement and ai1 for the trigger (for one machine), yet I see nothing in the documentation on how this is done. I have tried playing around with the DAQ express VI (I am using Labview7) but still don't see a way to have the setup I am looking for. I'm sure this is a relatively easy question, but I'm unsure where to go to look for an answer. Any helpful pointers or guidance in the right direction
would be very helpful!

If what you want to do is start the acquisition of channel 0 when channel 1 reaches the trigger condition and not start channel 2 until channel 3 reaches it's trigger condition, then no, you cna't do that unless you have multiple daq devices. What can be easily done is continuously acquire all channels and monitor your trigger channels. When the trigger condition is met, then perform the analysis/logging. On the Analyze>Waveform Monitoring palette is the Basic Level Trigger Detection function. Use one for each trigger channel and have it return either the index or relative time of the trigger occurance. This value can then be used to idex that portion of the measurement channel that you're interested in.

How to generate a delayed retriggerable pulse using only one counter with PXI 6070E card

Hi
I have a problem in generating a retriggerable delayed pulse with a single counter(triggered through a signal at gate) using PXI 6070E card. VI was developed in NI LabVIEW traditional DAQ Ver.7.1. I have used the "delayed pulse generator config" VI and a "Start counter" & "Stop counter" VIs for the purpose. But there is no output seen at the out terminal of counter. So I introduced a "wait" VI and set it to 1 sec. Now the pulse output appears but some pulses are missing mometarily after every 1 sec interval. (any solution for this)
I have gone through a few similar requests in the forum but they suggest either to use two counters or to generate a finite pulse train which does'nt fit my application. Moreover PXI 6070E has only 2 counter timers. I am already using one counter to measure the frequency of a pulse train(signal 1). The application requires to generate a delayed retriggerable pulse for every pulse in signal 1. So I have only one counter left.
Can I measure the frequency of signal 1 by analog means.? so that I can use two counters for pulse generation. (Signal 1 is a TTL signal).
Request some help.
Thanks in Advance
Regards

A finite pulse train (N_Pulses >= 2) does require the use of 2 counters on most of our older hardware including your 6070E. If you're just talking about generating a single retriggerable pulse, you would only need one counter.
Here's an example in Traditional DAQ that shows you how to set a retriggerable pulse generation (it also allows you to adjust the characteristics of the pulse on-the-fly).
If you're writing a new program, you might consider switching to DAQmx as it supports NI's latest hardware and recent OSes should you ever need to upgrade. Traditional NI DAQ is no longer in active development. Here's an example of how to implement a retriggerable pulse generation in DAQmx. You should take note that you can't use the two drivers to simultaneously talk to the same piece of hardware, although you should be able to go back and forth by resetting the Traditional DAQ driver before switching to DAQmx.
