How to measure and plot RMS value of real time data?

hi
i need to measure and plot real time RMS value of EMG voltage. I made a VI. But I dont know why it didn't work. Can anyone please help me out? My VI is attached in 2013 and 2011 both version. One sample data is also attached. Thanks at advance.

You seem to select EMG voltage vs Angle(Z-axis). Is that really what you want? More resasonable would seem e.g. EMG voltage vs. time.
If you want to process the 3D (xyz data), you probably need to add some more math). Why are you taking the absolute value? RMS does not care about the sign anyway, right?
They you are trying an XY graph with a single point, because your Y value is only a single number. You need an equal number of points for Y.
Here's a quick modification that graph EMG(mV) vs. time(ms) and takes the RMS of the EMG data. See if this gives you some ideas.
Please provide more information what you want to do with the angles.

TDMS database and treat its values as real time data.

Hi,
I'm newbie in using labview. Actually I wanna import data from TDMS database and treat it as real time data. Although I have done the first part which is importing the data inside the program by reading TDMS and selecting channels and groups, I couldn't find way for second part which is treating data as real time one. I tried Build Waveform, but it didnt work. Would you please help me to solve this problem ? I appreciate your helps.

reza_amin,
I don't understand your word "build waveform". If you write waveform data to a tdms file, you will read waveform data directly from the tdms file.
If you are using LabVIEW 2012 (download from http://www.ni.com/trylabview), you could find a tdms example VI in "C:\Program Files\National Instruments\LabVIEW 2012\examples\file\plat-tdms.llb\TDMS - Concurrent File Access.vi". This example VI demonstrates how to write Sine Waveform into a tdms file and read the Sine Waveform from the tdms file.
Hope this helps and enjoy your LabVIEW journey. :-)

New calculated member based on existing measure and a dimension value

Hi
I’m trying to create a new calculated member in my cube based on an existing measure and a dimension value.
I can do it easily in DSW but I want to do it as a Calculated Member in Calculations tab from my cube.
I have a dimension called Product in which one attribute is UOM (unit of measure) and a measure called Quantity. The relationship with the fact table is “Regular”.
For each product we have a unit of measure and an associated quantity measure:
Product Name
UOM     Quantity
Product 1
          Km
         50
Product 2
          Kg
         60
Product 3
          Kw
          25
Product 4              L
15
Product 5              T
         1.5
Total                                     151.5
The calculated member I want to create is “Kw” and has to contain the value from Quantity measure when Product.UOM is “kW” and should look like this:
Product Name
UOM     Quantity
Kw
Product 1
          Km
         50
Product 2
          Kg
         60
Product 3
          Kw
          25
25
Product 4              L
             15
Product 5              T
         1.5
Total                                     151.5
25
So far I tried using the MDX with “IIF” or “Case” but with no results.
What statement I should use in this case?
Thank you.

Hi Cees,
Thank you for your answer.
I never used yet the “Scope” statement and yet it’s an elegant solution.
I use it as in your example:
CREATE
MEMBER CURRENTCUBE.[Measures].[Kw]
AS NULL,
FORMAT_STRING =
VISIBLE = 1 ,
ASSOCIATED_MEASURE_GROUP =
'TR Other';
Scope [Measures].[Kw];
Scope [Product].[UOM].[kW];
This = [Measures].[Quantity];
End
Scope;
End
Scope;
…and the calculations are solid…with one exception: when I took out UOM from the query there are no more any resuts:
Product Name    Quantity    Kw
Total
It’s only working
if using UOM in the query.
I also thought that a
tulpe might be another solution as:
([Measures].[Quantity],[Product].[UOM].&[kW])
On this last one I’ve got the expected results with one exception: when I use UOM in the query all the other UOM values are listed each one of them
having the [Kw] measure calculation value.
Product Name    UOM     Quantity    Kw
Product 1              Km
         50
Product 2              Kg
         60
Product 3              Km
          25            25
Product 3              Kg
           25            25
Product 3              Kw
          25            25
Product 3              L
25            25
Product 3              T
25
  25
Product 4              L
            15
Product 5              T
         1.5
Total                                     151.5
25
…and without UOM in the query I have what I’m expected:
Product Name    Quantity
Kw
Product 1              50
Product 2              60
Product 3               25
25
Product 4
15
Product 5
1.5
Total                       151.5
25
Maybe we can work together to find a solution.
Thank you,

Display real time data on a plot in a sub VI and main VI

I am building a program to measure and plot real time data. Program has several steps so I build few Sub VIs to make it simple. My problem is I am plotting real time data in my SUB VI(it works fine), but in my main program when I try to get the same plot its not real time data plot. Plots appear at the end of the program. All tips and help would be greatly appreciated. Thanks

LabVIEW program is based on DATA FLOW, now, until the subVI will finish execution (while loop will be stopped), the execution in Main VI will not proceed any further.
If you can pass the reference of 'XY Graph' inside the subVI, you'll be able to update the plot (placed on MAIN VI) from within subVI.
Find attached example for your reference.

How to query in SCCM 2012 to know how many active and inactive clients in a specific time and date

Dear Everyone,
Good morning. I need to perform a query to know how many clients PCs are active or inactive during the a specific time and date (let say, today 9pm). In my query, I want to know:
1. How many client PCs is active at that time and date?
2. How many client PCs is not inactive at that time and date?
Any assistance is greatly appreciated. Thanks.

Thank you Gerry for pointing out that it doesn't show real time date. I do agree with that. However, I am look at the (at least in this) report which supposed to [description] shows a list of computers not reporting any power activity for a specified date
and time. Since I can only key in date in my selection (time option not given), I am expecting the report to show me whether there any client PCs that doesn't any power activity for the specified date. A list was generated, and a number of them shows HardwareInventoryScan,
LastHeartBeatScan and LastPolicyRequest on the same date itself. I would like to know why these appears, so that I can learn from it.
Due to the selection option given, I can't expect my original goal, but at least (hopefully) I can get to know (past event) how many and which client PCs is not powered on a particular date based on the date and collection selected.
At least by getting explainations, I hope to learn something from this (how to read this report). Thanks in advance.

How to drag and drop a picture at run time in a window displaying pictures?

How to drag and drop a picture at run time in a window displaying pictures on the front panel. The main thing is that the window is displaying frames continuously?

vivman,
So from your description you have a picture control where you've already created an image and you'd like to drag an image around inside of the picture control. This can be done although it is going to take a significant amount of research and programming on your behalf. You can use the drag event in the event handler to find out when the drag occurs and where the cursor is. Then edit the picture as you move your mouse so that when you drop the picture gets updated.
The even structure is a somewhat advanced topic and the drag and drop feature is one of the more advanced uses of this structure. I would search the example finder (help>>find examples) for "event" and "drag" to see how to use these events. Also you'll want to look at the examples for the picture control.
Sounds like a cool project! Check out Darren's Weekly Nugget 10/30/2006 this topic (http://forums.ni.com/ni/board/message?board.id=170&message.id=212920). It might prove useful.

How can I boot my PXI controller into real-time without a floppy disk?

My PXI controller is in a lab which has intense magnetic fields that could corrupt the floppy disk used to boot the PXI controller into the LabVIEW Real-Time (RT) Operating System. How can I boot the PXI controller into real-time directly from the hard drive?

If you are using LabVIEW 5.1.2 Real-Time (RT), launch Remote System Explorer and select Disks >> Create Format Hard Drive Disk. If you have LabVIEW 6 RT, launch the Measurement and Automation Explorer (MAX) and select Tools >> RT PXI Disk Utilities >> Create Format Hard Drive Disk (LabVIEW RT 6 has not be released yet). Once you have created the disk, boot the PXI controller with the Format Hard Drive Disk, and this will format the PXI's hard drive and install the real-time OS boot loader. Now you can reboot the PXI without a floppy disk and configure the PXI using Remote System Explorer or MAX. Be aware that this will remove all information from the hard drive, including other operating systems.

How to count occurences of a certain string in incoming real-time data? Also displaying RTC data. Current VI included

I use LabView student Express 7 on a Windows XP system.
Time-frame: we are doing final integrations for our balloon experiment today. We just got told that the press wants to view real-time data, which we haven't programmed for. I need help to get a working VI at the latest by 25.02.2004 before 0800(morning) (GMT+1).
Note on license
It is a student balloon flight, and the data will not be used in scientific work, so the I am not breaking any license agreements (I hope).
Problem synopsis:
The balloon continually transmits data at 9600baud. The data is a semi-repeating header followed by a constant lenght data-package arranged like this:
BEXUS[h][m][s]BEXUS[h][m][s]
[Raw binary data, 7channels*8sub-channels*8bits]
What the groundstation is doing right now:
Take all incomming data and save (append) the data to a file without any data-handling. (We figured we would go post-processing).
What I need to change in less than 24 hours:
- Add a "package" counter
- Add a display of the clock data (RTC)
How I planned to implement the changes:
-RTC display:
The RTC data is in BCD format, since that means that if you look at the data as hex numbers, you get the hours and minutes and seconds out in "clear text". That is 12 hours is 0x12hex. I figured that I can do a match pattern BEXUS and pass the "after substring" to another match pattern BEXUS from which I feed the "before substring" to a type-cast VI (casting string to u8) and displaying that, which should give me a display of "123000" for the time 12:30:00... I couldn't get it to work at all when I tried out the supplied "beta" vi.
- Package counter:
Counting how many BEXUS that gets detected and dividing by 2. I don't know how to do this. I've looked on the forum (a good thread on the problem: "how do I count the number of *'s in a string") but these use either loops or arrays... and I'm not sure how this works when I'm getting the data in at realtime. I cant make an array and then count it, since then the array would grow fast and possibly interfere with saving of the data??? Saving the data is critical.. without that file we cant do post-processing.
Since my time is so limited (I'm not even supposed to do the groundstation software but they called on me in the last minute because no-one else had time/wanted too/could do it) I hope that you could make an exception and provide me with working VI's (based on the one I have attached) so that I can show something to the press! (Free comercial for NI!! Since the student version shows the National Instruments water-mark on all VI's!!! Possible TV time!!)
Thanks!
PS: even if you are to late (after 25) post anyway!
Why:
-I can learn from it
-the launch might be delayed due to weather conditions
-others might find it amusing!
Thanks again!

I have a valid example data file attached to this thread.
If you open BEXTEST.bin in a hex-editor of your choice, you'll see the BEXUS as 42 45 58 55 53 and then the time as 00 28 09 etc.
I couldn't get Joe Guo's VI to work. It doesn't count packages correctly, and the time is not displayed correctly either.
The file was saved using a straight save to file VI.
The data is from actual launching area tests performed a few mintues ago. The time displayed is "On time" e.g. how long the gondola has been powered up.
I have a spare T-junction, so I can hook into the balloon real-time data as we fly, in case anyone care to see if they can figure out why the latest version of Joe Guo's program is not displaying correctly.
I will monitor this
thread during and after flight to see if anyone can make it in time!
Thanks for the great effort!!

Plotting a graph in real-time without reading from a file

Hello there.
I am trying to plot a graph. I have succeeded in plotting the graph by first writing the data to a text file (.TXT), then reading from that text file.
However, I feel this method will take up a lot of memory. Thus, I was wondering whether it is possible to plot the graph directly without first writing it to a text file.
Thanks a million.

You can use a while loop with a shift register, inside the while loop, put a case structure, and in it, your data aquisition vi. When you get data, use the shift register to append data to the array, using build array (the shift register will go in as an array, and data as an element) just execute the appending state when data is present, and you'll have a real time graph.
Hope this helps

How to Integrate real time data between 2 database servers

How to Integrate real time data between 2 database servers
May 31, 2006 2:45 AM
I have a scenario where the data base (DB2 400) is maintained by AS 400 application and my new website application based on j2ee platform access the same database also but the performance is very low. So we have thought of introducing new oracle data base which will be accessed by j2ee application and all the data from db 400 database will be replicate to oracle data base. In that scenario the only problem is of real time data exchange between 2 databases. How do we achieve that considering both the application As400 and j2ee website application are running in parallel and accessing the same information lying on DB2 400 database. We have to look at transaction management also.

You certainly wouldn't use XML for this.
The process you're looking for is called "replication". Ask your database experts about it.
I predict that after you spend all the money to install Oracle and hire consultants to make it replicate the DB2/400 database, your performance problem will be worse.

Yeajh I now that its not a XML solution.
Replication is one of the option but AS400 application which uses DB2/400 DB is highly loaded and proposed website also uses the same database for retrieval and updation purpose.All the inventory is maintained in the DB2/400 database so I have thought of introducing new oracle database which will be accessed by new website and it will have all the relevant tables structure along with data from DB2/400 application. Now whenever there is a order placement from new website then first it should update the oracle database and then this data shuold also migrate to db2/400 application at real time so that the main inventory which is lying on db2/400 should be updated on real time basis because order placement is aslo possible from As400 application. So the user from As400 application should not get the wrong data.
Is it possible to use MQ products??
-Panky

Hi,
the answer to your question is not easy. Synchronization or integration or replication data between 2 (or more) database servers is very complicated task, even though it doesn't look like.
Firstly I would recommend to create good analysis regarding data flow.
Important things are:
1) what is primary side for data creation. In other words on which side - DB2 or Oracle - are primary data (they are created here) and on which side are secondary data (just copies)
2) on which side are data changed - only in DB2 side or only on Oracle side or on both sides
3) Are there data which are changed on both side concurrently? If so how should be conflicts solved?
4) What does it mean "real time"? Is it up to 1 ms or 1s or 1 min or 1 hour?
5) What should be done when replication will not work? I mean replication crash etc.
BTW. The word "change" above means INSERT, UPDATE, DELETE commands.
Analysis should be done for every column in every table. When analysis is ready you can select the best system for your solution (Oracle replication, Sybase replication server, MQ, EJB or your proprietary solution). Without analysis it will be IMHO gunshot into the dark.

AE CS6: How to Ram preview or playback in smooth real-time everytime?

Hi guys,
I would like to know how to Ram preview or playback in smooth real-time everytime? I'm using a videohive template and adding in my footages to the media holder comps. The AE template is complex I guess.
Hee's the problem, everytime I make a change to text, add a footage replacement or make any change at all, I have to completely render and wait a long time to see my final product in "Real-time"/smooth. Is there someway that I can render out the whole thing once and even though I make a change the entire video will play smoothly without rendering time?
PC Specs:
HP 510t
Windows 8 Pro x64 bit
16GB Ram
i7 2600 CPU @3.4 GHz
GTX 660Ti

Proxies don't affect rendering beyond the point of reducing the resolution and thus the nuimer of pixels that need to be processed, but since the retain the effect properties at full resolution, e.g. a large blur still renders just as slow. They are more a means of reducing file I/O bandwidth while working really.... As I said, the best way to optimize this would probably be to restructure the project so parts that don't change reside in separate pre-compositions and can use the disk cache.

How to get the real-time data from a CCD camera in labview?

I am going to setup a monitor system and need to acquire the intensity of each pixel at each second from a CCD camera. Also, I need to to some simple calculations with these real-time data at every moment to get my finanl output in this monitor system.
How may I do this using Labview?
Thank you very much.

We don't have special powers, so we can't guess if you have Imaq Vision or not, if your camera comes with a LabVIEW driver, if it has an USB interface, or firewire, or a dedicated NI card, if you just want to detect a move, or a change in intensity, etc...
So, try to be more specific with your question, that will helps a lot

How to get real time date from Sunny Boy Inverters through SMA Webbox?

Hello,
I was looking on how to communicate with three Sunny Boy Inverters that are linked to a SMA webbox. Currently we get a daily summary of the solar production, but we would like to have real time data uploaded into LabVIEW. The people of SMA said that I needed to use "RS485 protocols" with a software they have called YASDI (http://www.sma.de/en/products/software/yasdi.html); however, I keep finding other information that says that I can communicate with my inverters using the SMA OPC server (http://www.sma-america.com/en_US/products/software/sma-opc-server.html). I also found this forum, http://forums.ni.com/t5/LabVIEW/Sunny-Island/m-p/809129/highlight/true#M368718, where I understood that I don't need to use the OPC server, but instead I can use UDP communication to get the data. I found another forum that talks about using the YASDI :http://forums.ni.com/t5/LabVIEW/help-with-Sunny-Boy-inverter/m-p/293273/highlight/true#M153892.
I've tried to communicate with the people of the forums and I haven't gotten any responses; therefore, I wanted to see if I can get cleared up on this issue. Do I need to use OPC server to communicate with my inverters through the webbox or can I just use UDP in LabVIEW?
Any help would be greatly appreciated,
Thanks

Hello,

Since the PRC protocols to communicate with the webbox are in JavaScript Object Notation (JSON), I'm not sure if the data-in string has to be in JSON format. However, the only error I'm getting is 56 in the UDP read function. I've tried increasing the size of the bytes and timeout, but I keep getting this error. If anyone can help me with this part I would very grateful.
