Datalogging and Supervisory Control : how to share data among LabVIEW applications on the same network?

I'm new to DSC. Is there an example program or article about how to share data (live data and data saved after running a program) among LabVIEW (using DSC) that is very basic? I would like to share live data and test reult data (eg. excel) among computers on the same network (may be LAN). Does sharing data over a network by using DSC makes whole system (all computers) down when one computer is locked up?

Hi,
The easiest way to network DSC data is using "network tags". The way you do it is by simply configuring the server PC as you normally would do for a local application.
Then from a remote compute, which we can call a client computer you can go to Tag Configuration Editor and option "File >> Import Network Tags.."
In the window that opens up you can hit the browse buttom and navigate to your server computer, select the .scf file you want to have and hit the buttom import.
Save the "client .scf" file locally and now you have in the client the same configuration you have in the server and your data is networked, from there on is just a matter of manipulating the data.
I hope it helps

How can I connect my mobile device on the same network with my printer

I have pictures on my mobile device but I am unable to print them on my HP Photosmart plus printer. I was wondering how am I able to make sure that my printer and my mobile device is on the same network so I can print my pictures or either be able to save them to my memory card?

Hi,
Are you talking about iPad, iPhone ?? If YES then please check your printer on this list,(updated on 15Dec2011) it must be an AirPrint enabled printer to be able to print from iPad, iPhone. If YES (again), you can use AirPrint on your iPad to print.
Regards.

How to acquire data from multiple dataports at the same time

Hi,
I studied the multithreading section of Labview, but still have no idea
how to make it work. Let me briefly explain my situation. I need to
develop a program that can control and acquire data from 4 serial
ports. I have 4 buttons to control starting or stopping acquisation
from the corresponding port. Every acquisation process is a while loop.
How can I start a new acquisation loop (eg. from COM2) while the loop
for COM1 is still running? In other words, I wish the 4 loops running
independently, and are controlled by their corresponding buttons only.
Thanks for any suggestion.

Hi Anonymous,
If I were you, I'd create one VI (call it Port.vi) to listen to one port - then make it reentrant. Drop 4 copies of Port.vi on your Main diagram. Port.vi inputs could include a VISA reference, a "Start/Stop" notifier and maybe a "Quit" occurance. Wire to each copy of Port.vi a unique VISA reference and a unique "Start/Stop" [boolean] notifier - let all the copies share the same Quit Occurance.
In Main, have one event case for each of your stop buttons. When a button is pressed, send the appropriate Start/Stop notifier!
... of course you could accomplish the same thing with four identical loops right in your main diagram, but the more complex the port-handling gets, the easier it will be to manage in one place instead of four.
Cheers!

How to share iTunes with two users on the same mac.

My wife & I use the same iMac with different user accounts. How do we share one iTunes account on that computer. I tried moving the iTunes folder in music on my user account to shared user, but it seems like new iTunes folders are created in the original location when I do this. What am I doing wrong.

How to copy data of a table to the same but on a DIFFERENT MACHINE?

Hello experts,
I want to copy all entries of table TE422 to the same, but on a different machine. I created a transport request (workbench request using TABU) intending to copy the entire table data from QA into DEV environment.
However, this is not working, because, in our installation, QA is on one server, and DEV on another! So, in a way, each machine seem to be transparent to the other and I cannot, or, do not know, how to specify the DEV environment as target.
I was told that I have to do something at the OS level. That is to say, have some kind of SQL query which collects data from one and uploads it onto the other.
Now my question is: Is there a SAP way to do this, that is to say, forget the SQL thingy and do it with some SAP transaction? If yes, how? If not, do you have a sample code which does this please?
Your help is greatly appreciated.
Goharjou

Method 1:
You can transport using ALE/IDOC, Write a simple outbound function moule in Source System and Develop a Inbound function module in target system.
Method 2:
Download the entire table contents into a flat file from source system by developing a simple report using WS_DOWNLOAD function module. Then Develop a report using WS_UPLOAD in target system and upload thd flat file.
Thanks & Regards,

How to transfer data between different nodes of the same context.

Hi Vaibhav,
you are in the wrong forum.
BTW: Copying value of nodes is done automaticcally if you connect the nodes.

How to store data while Labview can overwrite the unwanted data

Hi,
My name is
Panakalu. Currently I am doing a project using Labview. I need a help
from anyone of you. I am in desperate need of help. Here is my problem.
I want to acquire data from a arbitrary generator. Actually I have to
store transients from a device. This process is going to run for
atleast 8 hours. So I cannot store all the data acquired. This made me
to I keep a threshold level for the acquired transients. So please any
body tell me how I can overwrite the data which is below the threshold
level and continue writing the data to hard disk when the data is above
the threshold level. Also I have to store this data in different files.
That is for every 5 seconds I have to store the data into another file.
If the first 5 seconds data is stored in a file named data1.xls, then
the next 5 seconds data should be stored into a file named data2.xls.
Like this I have get 100 different files. I am using third party
drivers for labview. My data acquisition card is from EXACQ
TECHNOLOGIES.
Please help me in this matter. Your help in this matter is really
appreciated.
Thanking You All
Panakalu

Take one step at a time.
To write data to a file every 5 minutes, it might be best to accumulate the data into an array. Use a while loop. Collect the data inside the loop and check if it is above threshold. If so, append it to the array. Inside the loop you can check the time. If 5 minutes have elapsed, exit the loop. After exiting loop, write to a file. A big loop must surround all this code to repeat it over and over. The big loop can create the file name. Use the i terminal, convert the number to a character, and conatenate the character to the basic file name, like "data" + "2" + ".xls". Try this on you own, post your code, and we can continue to help you with problems.

How to share apps on 2 Macs with the same Apple ID ?

Hi,
I got a new iMac (2013 - Mavericks), and I gave my old one (2010 - Lion) to my husband. I've downloaded some new games on the Apple Store with my Apple ID for my new Mac, and it works fine. But when my husband wants to install them on his Mac, when he types the password for my Apple ID, it doesn't work, it says "wrong user/password"...
It seems that once I've activated my Apple ID on my new Mac, it prevented the old one to use it ?? The Home Sharing is turned on, but apparently it only concerns iTunes (music, etc), but not the NEW apps from the App Store. Everything new on my Mac can't be shared with the old Mac.
What can I do ? We don't want to create a new Apple ID for my husband, because we don't want to lose what there is already on his old Mac (we use the same music, games, apps, etc).
Thanks for your help.

Welcome to the Apple community.
If we means 2, then you are best keeping seperate accounts. What you need to do is share photo stream albums with the other.

How to share iphoto with two users in the same imac maverick

I can´t find the way to share iphoto/itunes with two users in the same imac with maverick software

In conclusion, the new software is worse than the old one, really? Because in my old mac I could share easily without copy with an external USB
It's not iPhoto that dropped the ball but the system. I believe it was Mavericks that broke the Shared folder compatibility for iPhoto, not iPhoto itself.
Also having the library on an external HD is a good way of freeing up space on the boot drive to assure optional system and application performance.

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 load data using two maps for the same source file in Import Manager

Hi,
I am trying to load the source data to MDM using two map files, since one map is too big (creating memory error).
However the first map data able to see after loading (SAP data) but when loading second map(nonSAP data) using the remote key to match the previously loaded SAP key ,even if MDM is processing the data it is not reflecting in data manager.
Is there any reason for this.
Appreciate your suggestion and tips on this.
regrds,
Reo

Hi Reo,
As ur requirement seems,In the second pass perform recording matching by select default import action as "update null fields only" for those data records which are matching and "create " for those data records which are not matching with previous data records from SAP system.
If you define "update null fields only", then only the key of the new record from NON SAP will get appended to the existing record. And if you select "create" then it will create new records and will apply NON SAP key on it.
Please check the remote key values using data manager.Key is applied in the records or not.
Remember that import maps are client specific. Remote key comprises of both key and client system.So be sure that you are connecting to two different client systems.
I have tried this and this is working fine on my system.
Thanks,
Shiv Prashant Dixit

Please help me out -How to share a single indd. file at the same time?

Is there any any option for two users to work on a single indd. file at the same time. (Just like working on a shared file in Microsoft Excel).
Note both make changes at the time on different pages.
To save time...

Another option, if the file is a large mupltiple page design, is to divide the document into chapters or sections. Save each section as a separate InDesign file and then combine them using a book (.indb). File > New > Book...
Different users could edit the individual sections or chapters, and then when all is ready to go, the book can be used to package the documents, export to PDF, etc.
Not very efficient for small documents, but it can make life easier for long documents.
