How to optimize data logging in my code?

I have my program working well enough to have it run some trials in the lab. It was run under some 'extreme' conditions to make sure data acquisiton and logging is working well.
With frequency being 1000Hz, he requirements are that the relay goes ON for 20ms and and stays off for 250ms. This 250ms should equate to 250samples gathered.
After a run, the saved files range from 240 to 280 samples for a 250ms setting, but some are as little as 150 samples. I need to ensure that the correct number is logged, a +/- 5% variation is 'OK' but when the samples gathered are close to half of the desired is unacceptable.
I need the graphs wired to 'data[0]' and 'data[1]' to update in real time, to be smooth.
Any suggestions? Every time my consumer loop executes, how many samples does my DAQmx Read, at current, receive? I do not think it's an issue w DAQmx setup, but I am not 100% sure..

Is there any reason you're not using compound arithmatic to get into the logging loop? What happens in those false cases? If you're just wiring everything through, you'd be better served to only use one case structure. Feed all three boolean values into a single compound arithmatic set to AND. If all three are true, after the NOT used to invert the false value, it will enter the true case. Otherwise, it'll enter the false case. It's the same logic, but it's handled better.
You might consider taking a look at Producer/Consumer or Queued Message Handler. You can use these to send a message to an external while loop. If you have multiple cores, this makes it easy to split the task to read data on one core and leave it mostly unaffected by the logging process done on another core.

How to reset data for the company code 1000

Hi Gurus,
I am practicing SAP SD on a sandbox server as am learning it.
But i see that the standard data for the company code 1000 has been altered by previous users and most of the standard setttings have been changed.
Due to this am having a lot of issues while configuring a new company code by copying it from 1000.
Please help me reseting the data for the company code 1000 so that it will be easier for customizing and learning.
Regards,
Harish

Hi Harish,
Follow the step given below
SPRO --> Enterprise Structure --> Definition --> Financial Accounting --> Edit, Copy, Delete, Check Company Code
A pop screen will appear which will give you two options
1) Copy, delete, check company code
2) Edit Company Code Data
Select option one
On next screen --> Click at " Check org. object" or press F8 --> It will ask your company code --> enter your company code 1000 --> Enter
It will check all the related table and if it find any discrepency
then it will show you one pop up screen

I have an optical sensor and two hall effect how can I data log?

I have built a test rig which consists of a gyroscope. The gyro is spun up by and electric motor.
I need to measure the speed of rotation. I’m using an optical sensor and two Hall
Effect sensors. I would like to record the
output of these and I would like to build in some redundancy because there will
be another bigger rig that will require more measurement. E.g. vibration.
I’m new to data logging so I’m not sure which hardware I
should be getting.
Thanks

analog inputs are the most universal. with software such as the functions included in the Sound and Vibration Measurement Suite, you can analyze the analog input channel which is connected to your hall effect and optical sensors for frequency and speed. Vibration specific input cards will power accelerometers. with the speed and angular position sensors (hall effect and optical) you can combine this information with your vibration sensors to determine the movement of the device with respect to position and speed. These order analysis functions are part of the Sound and Vibration Measurement Suite.
What is more is that the Suite includes an assistant. The assistant allows for the capture and datalogging of all analog and digital inputs as well as frequency and vibration analysis. This is all configurable and does not require any LabVIEW programming. If you decide you want LabVIEW programming, all the functions are there to support LabVIEW as well.

How to optimize the performance of this code ?

I've two Movie clips on a flash project. One of them is fixed and the other can be moved by arrow buttons on the keyboard. The two Movie clips have irregular shapes, so HitTestObject and HitTestPoint doesn't work very well. I've a function that detects collision of two movie clips using bitmap. I wanted to update the position of the movable Movie clip so I put the collision detection function under the code of ENTER_FRAME event listener. It works very well, but when I add many fixed movie clips ( about 10 fixed movie clips in one frame ), the game (.swf file) becomes slower and the performance of the PC becomes slower. I thought that my collision detection function has a negative effect on PC performance so I used the class on this page : https://forums.adobe.com/thread/873737
but the same thing happens.
Would you tell me how to speed up the execution of my codes ?
Here is part of my code :
stage.addEventListener(Event.ENTER_FRAME, myOnEnterFrame);
function myOnEnterFrame(event:Event):void
if (doThisFn) // doThisFn is a variable to allow or prevent the movable movie clip form being moved with keyboard arrows
if ( left && !right ) {
player.x -= speed;
player.rotation = player.rotation - speed ;
if( right && !left ) {
player.x += speed;
player.rotation = player.rotation + speed ;
if( up && !down ) {
player.y -= speed;
if( down && !up ) {
player.y += speed;
// The fixed movie clips are wall1 ,wall2 , wall3 , wall4 , ... and so on
// the following code checks how many walls exists on each frame and pushes them into the wallA array
for(var i:int=0;i<1000;i++) // We can put up to 1000 wall object into the wallA array
if(this['wall'+i]) // If the object wall exists, push it into the wallA array
wallA.push(this['wall'+i]);
for(i=0;i<wallA.length;i++)
if( h.hitF (player , wallA[i] ) || gameOverTest ) // This code checks if the player ( the movable movie clip ) hits the walls or not
trace ( "second try" ) ;
gameOver.visible = true ;
doThisFn = false ;
//I think the following codes are easy to excite and run. I think the performance issue is due to previous codes.
if (player.hitTestObject(door))
win.visible = true ;
doThisFn = false ;
if (key) // if there is a key on frame
if (player.hitTestObject(key))
key.visible = false ;
switch( currentFrame )
case 4:
wallA[0].visible = false ;
wallA[0].x = 50000;
break;
case 5:
wall14.play();
wall8.x = 430 ;
break;

it's a simple question that usually has no simple answer.
here's an excerpt from a book (Flash Game Development: In a Social, Mobile and 3D World) i wrote.
Optimization Techniques
Unfortunately, I know of no completely satisfactory way to organize this information. In what follows, I discuss memory management first with sub-topics listed in alphabetical order. Then I discuss CPU/GPU management with sub-topics listed in alphabetical order.
That may seem logical but there are, at least, two problems with that organization.
1. I do not believe it is the most helpful way to organize this information.
2. Memory management affects CPU/GPU usage, so everything in the Memory Management section could also be listed in the CPU/GPU section.
Anyway, I am going to also list the information two other ways, from easiest to hardest to implement and from greatest to least benefit.
Both of those later listings are subjective and are dependent on developer experience and capabilities, as well as, the test situation and test environment. I very much doubt there would be a consensus on ordering of these lists. Nevertheless, I think they still are worthwhile.
Easiest to Hardest to Implement
1. Do not use Filters.
2. Always use reverse for-loops and avoid do-loops and avoid while-loops.
3. Explicitly stop Timers to ready them for gc (garbage collection).
4. Use weak event listeners and remove listeners.
5. Strictly type variables whenever possible.
6. Explicitly disable mouse interactivity when mouse interactivity not needed.
7. Replace dispatchEvents with callback functions whenever possible.
8. Stop Sounds to enable Sounds and SoundChannels to be gc'd.
9. Use the most basic DisplayObject needed.
10. Always use cacheAsBitmap and cacheAsBitmapMatrix with air apps (i.e., mobile devices).
11. Reuse Objects whenever possible.
12. Event.ENTER_FRAME loops: Use different listeners and different listener functions applied to as few DisplayObjects as possible.
13. Pool Objects instead of creating and gc'ing Objects.
14. Use partial blitting.
15. Use stage blitting.
16. Use Stage3D
Greatest to Least Benefit
Use stage blitting (if there is enough system memory).
Use Stage3D.
Use partial blitting.
Use cacheAsBitmap and cacheAsBitmapMatrix with mobile devices.
Explicitly disable mouse interactivity when mouse interactivity not needed.
Do not use Filters.

How do I control a data log session with period and sample time?

I need a data logging system where the operator can select 2 logging parameters: Log Period and Sample Time. I also need a START and STOP button to control the logging session. For example, set the log period for 1 hour and the sampling time for 1 second. (I may be using the wrong jargon here.) In this case when the START button is clicked, the system starts logging for 1 second. An hour later, it logs data for another second, and so on until the operator clicks the STOP button. (I will also include a time limit so the logging session will automatically stop after a certain amount of time has elapsed.)
It’s important that when the STOP button is clicked, that the system promptly stops logging. I cannot have the operator wait for up to an hour.
Note that a logging session could last for several days. The application here involves a ship towing a barge at sea where they want to monitor and data log tow line tension. While the system is logging, I need the graph X-axis (autoscaled) to show the date and time. (I’m having trouble getting the graph to show the correct date and time.) For this application, I also need the system to promptly start data logging at a continuous high rate during alarm conditions.
Of course I need to archive the data and retrieve it later for analysis. I think this part I can handle.
Please make a recommendation for program control and provide sample code if you can. It’s the program control concepts that I think I mostly need help here. I also wish to use the Strip Chart Update Mode so the operator can easily view the entire logging session.
DAQ Hardware: Not Selected Yet
LabVIEW Version: 6.1 (Feel free to recommend a v7 solution because I need to soon get it anyway.)
Operating System: Win 2000
In summary:
How do I control a graphing (data log) session for both period and sample time?
How do I stop the session without having to wait for the period to end?
How do I automatically interrupt and control a session during alarm conditions?
Does it make a difference if there is more than one graph (or chart) involved where there are variable sample rates?
Thanks,
Dave

Hello Dave,
Sounds like you have quite the system to set up here. It doesn�t look like you are doing anything terribly complicated. You should be able to modify different examples for the different parts of your application. Examples are always the best place to start.
For analog input, the �Cont Acq&Chart (buffered).vi� example is a great place to start. You can set the scan rate (scans/second) and how many different input channels you want to acquire. This example has its own stop button; it should be a simple matter to add a manual start button. To manually set how long the application runs, you could add a 100 ms delay to each iteration of the while loop (recommended anyway to allow processor to multi-task) and add a control that sets the number
of iterations of the while loop.
For logging data, a great example is the �Cont Acq to File (binary).vi� example.
For different sample rate for different input lines, you could use two parallel loops both running the first example mentioned above. The data would not be able to be displayed on the same graph, however.
If you have more specific questions about any of the different parts of your application, let me know and I�ll b happy to look further into it.
Have a nice day!

How to intercept and log pushed data?

Hi, I'm a newbie , but I would like to intercept and log to file some real time data pushed on a page with stock values . Is it possible ? I need a hint , where to start . I've looked at the page, there is a javascript :

Is it possible ? Depends.
I need a hint , where to start . If this was your site, I'd say it'd be easy to do with filters or aspects.
I've looked at the page, Whose page is it? How much control do you have over code? My guess? None, because the person that owns that page has no idea what you're doing.

How to get the values from struct data type using java code..?

Hi ,
I am newer to java.
we are using oracle database.
How to get the data from struct data type using java code.
Thanks in Advance.

Hi Rajeev,
To retrieve a FilterContainer you will need to traverse the report structure:
ReportStructure boReportStructure = boDocumentInstance.getStructure();
ReportContainer boReportContainer = (ReportContainer) boReportStructure.getReportElement(0);
FilterContainer boFilterContainer = null;
if (boReportContainer.hasFilter()) {
boFilterContainer = boReportContainer.getFilter();
} else {
boFilterContainer = boReportContainer.createFilter(LogicalOperator.AND);
Calling boDocumentInstance.getStructure() will retrieve the entire structure for the document.
Calling boReportStructure.getReportElement(0) will retrieve the structure for the first report of the document.
Hope this helps.

Dan

With journaling, I have found that my computer is saving a large amount of data, logs of all the changes I make to files; how can I clean up these logs?

With journaling, I have found that my computer is saving a large amount of data, logs of all the changes I make to files; how can I clean up these logs?
For example, in Notes, I have written three notes; however if I click on 'All On My Mac' on the side bar, I see about 10 different versions of each note I make, it saves a version every time I add or delete a sentence.
I also noticed, that when I write an email, Mail saves about 10 or more draft versions before the final is sent.
I understand that all this journaling provides a level of security, and prevents data lost; but I was wondering, is there a function to clean up journal logs once in a while?
Thanks

Are you using Microsoft word? Microsoft thinks the users are idiots. They put up a lot of pointless messages that annoy & worry users. I have seen this message from Microsoft word. It's annoying.
As BDaqua points out...
When you copy information via edit > copy, command + c, edit > cut, or command +x, you place the information on the clipboard. When you paste information, edit > paste or command + v, you copy information from the clipboard to your data file.
If you edit > cut or command + x and you do not paste the information and you quite Word, you could be loosing information. Microsoft is very worried about this. When you quite Word, Microsoft checks if there is information on the clipboard & if so, Microsoft puts out this message.
You should be saving your work more than once a day. I'd save every 5 minutes. command + s does a save.

How to send data to labview code at run time while using with (or executing the sequence)the teststand

Hello
I am new to the Teststand.
I am using labview8.0 with teststand 3.1
I have developed some labview codemodules as vi's without using the teststand utility library pallete
Now i have to run them in teststand.
While executing them(as a sequence) in teststand,i need to enter the data to the labview code at run time.For this labview front panel should appear as GUI or popup (while executing).Is it possible to do this without using teststand pallete.
or i need to change the code with teststand pallete(i think it is difficult now to change the code)
Plz provide a solution to this problem
Also one more,how and where to use the 'pass by reference' option
Thanks and Regards

Hi,
see your other post http://forums.ni.com/ni/board/message?board.id=330&message.id=13914
Also, you can, specify to display the front panel of your VI when you specify your VI in your sequence file.
There are examples, for dialog panel using LabVIEW, in the examples folder of TestStand and on the NI Web Site.

Data logging optimization function in LabVIEW and SignalExpress

Hello, everyone! I and a colleague have assembled the attached VI,
which is used to control a plant growth chamber, and I could use some advice.
I would like to add data logging capabilities, ideally to note (1)
environmental conditions, such as temp and CO2 level and (2) when certain
situations occur, such as high CO2 or low pressure (which results in a change
to the “Case Structure for CO2 and Pressure”).
The chamber runs for weeks at a time, though, so I have a constraint.
Instead of continuously logging all the environmental data (which would yield
giant file sizes), I want to be able to take “snapshots”, say every 5 minutes,
so I can examine the chamber’s condition over a long period of time.
I attempted to use the Time Delay function to control the Write Measurements
function (as in LabVIEW’s Cycle Analysis example, which I’ve also attached),
but Time Delay halted my entire program.
I also tried the Wait (ms) function, but had no success.
I recently discovered the powerful data review and reporting tools that
SignalExpress has to offer. Ideally, I
would like to use a SignalExpress express VI to record the measurements instead of the more primative Write Measurements, but, I’m not sure how to implement this in my VI. For example, would I make a data acquisition VI in SignalExpress for all my sensors, export to LabVIEW, and use that to replace the current DAQ structure in my VI? (Because the chamber VI is interactive, I'm pretty sure that porting the LabVIEW VI to SignalExpress wouldn't work out well.) And I’m
still not sure how to control how often it records measurements.
Any advice would be much appreciated!

Hi, Sarah. Yes I definitely plan to use LabVIEW for the majority of my data acquisition and logging. I apologize, I think I probably should have broken my post into two separate posts for clarity, as my major concern is being able to set how often LabVIEW logs the environmental data (viewing the logged data in SignalExpress would be nice, but not a requirement).
As I explained before, I'd really like to be able to set up a system that records the environmental condtions at regular time intervals, say every 30 minutes, or if my "Case Structure for CO2 and Pressure" status changes (such as from "Normal Conditions" to "High CO2".
As an example, attached is a boolean structure (TimedWritedMeasurements.vi) that I came up with to record a simulated signal every 5 seconds (5000 ms). Once I can get it to work, I would connect the boolean to my environmental sensor outputs and CO2 and Pressure case structure in my Chamber VI.vi that I attached in my first post.
My problem is I can't seem to get the Trigger and Gate function to work the way I'd like. I'd like the Wait (ms) function to trigger the Trigger and Gate function every 5 seconds to change the case structure in the TimedWriteMeasurements.vi to "True", thereby causing the Write Measurement function to record the environmental conditions. Then I'd like the case structure reset to false, until it's triggered to true in another five seconds. Can anyone point me in the right direction?

How does committed date in STO- different company codes gets calculated

Dear All,
Please let us know How does committed date (ATP date) in the STO across different company codes gets calculated

Hello,
RA is always a Company Code specific process due to the possibility of financial postings. I think that your WBS structure better be reconsidered not to mix up different Company codes at different levels, but maybe having a parallel nodes for different Company codes.
I also believe there is a consulting OSS note to explain the standard system behavior, just search the OSS.
Since you already have a master data in place it must be quite easy for you to test how the system behaves.

How to upload company code data related to Company Code BP01 FOR CIN?

Hi,
First check whether all the pre-requisites are completed.
I'm assuming you have installed the Best Practices Baseline package (for country IN). If you have succeeded in actvating the buildig blocks (as per your scope) using Solution Builder, you would have populated all the company code data related to Co. code BP01. Looks like some steps are missing.
Please refer to the OSS note 1408706 in this regard. From there, you also can refer to the "Quick Guide to Implementing the SAP Best Practices Baseline Package V1.604 (DE), which is self-explanatory.
Let me know if this helps.
