Help! Need for communication in real-time between a portable laptops 12-20 teacher students (wireless network)

Hello

I'm trying to delvelop software (Labview) that is installed on the student laptops (12-20 max) who reads data continusly (max 1 to 10 hz) of the computer laptop instructors. It tells me that the use of a text file and have the students to read continuously is not a viable option. Any help would be greatly appreiciated. I write mostly programs data type simple aquistion strain of measurers LVDT etc. as an engineer. I'm not a full time programmer, so I'm learning as necessary. The data is constantly simple double prescision updated of a simulation.

This will be a freebie for schools software later. Help, please...  Thank you

Well, you can also use TCP instead of UDP.  The TCP network protocol provides a bit more load to ensure that packets arrive in order and will be sent if missed.  That does not necessarily all the data arrive.  Disconnect a cable network for a short period of time, and a sent packet eventually timeout and exit.  But the internet tracks on this Protocol good enough, (at least that's what I said ) so I'm sure that it will work reliably enough for your small network application.

If you need other insurance, all your data arrives, so you can serialize each data package yourself, put a sequential number in communication with other data.  If the receiving program detects a missing number or one out of order, then at least you know your application level and can do something.  But I seriously doubt that your application is so critical that you need to worry about the implementation of this.  Just rely on TCP and you'll be fine.

    Help! I have a laptop Vostro 1500 that I bring to work and he need to log on to the network wireless to work.  I also have a wireless home network and have it automatically log this one as well.  I can get it to work properly on a network, until I have to log on to the other network.  Then he opens a session on the homepage of 2? or 2 working.  It's a real pain, because then I have to cross and re configure it once again.  Is it possible to just connect the existing network?  My laptop runs Vista Bussiness and other workstations on two XP pro media.

    1 - prevention of real time duplication

    2 - match of real-time reference


    Now guests feel difficulty to go with approach 1, which is demanding a better interaction between the application UI and OEDQ (developed in JAVA). They are not agree with solution 1.


    Now approach 2 is ok, but the reference file change dynamically through this UI application, now I need update OEDQ reference data respectfully change data, but this will require downtime of the web service and re-read that take about 10 min (700 K records).

    so, what could be the solution for this scenario?





    Hi Mike,.

    Thanks a lot for your fast turn around.

    Yes, I agree but not ready to implement the first solution, then I'm left with the second client option.

  • Deployment of local variables shared on a real-time target

    Hello everyone, once again

    I read more posts and knowledge base articles about this topic than I can count at this point, and I'm scared, I'm still not clear on exactly how it works, and I hope that someone can delete it for me, if it is to earn themselves some laurels more.

    I have a project with a real-time quote and the other Windows.  They shared communication via network-published variables.  The real-time part also uses shared single process variables to communicate between the loops.  I have the intention of all 3 libraries of shared variables (Windows-> RT, RT-> Windows and RT Local) to be hosted on RT target for reliability.  Real-time executable must start at startup and run even if side Windows is not started (on the side of Windows is optional).

    I realized that real-time executable will not start the variable engine shared and/or deploy itself shared variables.  I also read that I can't deploy the shared variables programmatically from the side of RT.  This leaves only two options that I know of:

    (1) their deployment programmatically in Windows-side program.

    (2) deploying the shared variables on the target RT manually via the project in the LabVIEW development environment, and

    About option 1, as I said running Windows is supposed to be optional, so you have to run a program on the Windows side before the side RT will work is highly undesirable.  Moreover, even if I do a little "Deploy shared variable" application that runs at Windows startup, I can't guarantee that it will work before start of the side RT executable will run.  In this case, the executable file RT will fail due to not having the variable engine shared running?  If so, and side Windows, and then starts the engine / deploys the shared variables, the side RT begins to work automatically?  If not, is it possible to trigger this restart of the Windows startup application side?

    Also, I just read everything and tried the option to build to deploy variables shared in the application of the side Windows.  Not only that my RT shared Local Library variables not listed as an option (given that the application of the side Windows does refer to it in all for obvious reasons), but when it deployed two other libraries at startup, the program side of RT (which was running in the development environment) stopped.  I'm not positive that would happen even if he was running like a real executable file, but it is certainly enough to make me nervous.  I assumed that the library is not listed may be resolved by including a variable network-a published in the local library of RT and including the app side Windows.

    About option 2, I don't understand how I'm supposed to deploy my libraries shared variables without stopping the execution of the startup on the target real-time application.  Once I did, the only way to restart the application of the RT is to restart the computer RT, correct?  In this case, I just undid all the interest to deploy the shared variable libraries?  Unless libraries remain deployed and variable motor shared running even after restarting the computer of RT, which would solve the problem I guess.  Certainly, I would like to know if this is the case.

    However, option 2 is complicated by the fact that when I manually right-click on any of my shared variables libraries and select "Deploy" or 'Deploy all', libraries still do not appear in the Manager of the distributed systems, even after clicking Refresh several times, on the local system or the target system.  The only thing that shows up, on both sides, is the Group of 'System', with FieldPoint, etc. in it.  The same is true when I run my application in real-time in the development environment, even if the shared variables are clearly working, as I mentioned earlier.

    So, if you have done so far through this mammoth post, thanks!  I have three main questions:

    (1) are that all my descriptions above correct in what concerns the variables how work sharing?

    (2) what is the best way to meet the requirements I have described above for my project?

    (3) why shared variables libraries not appearing in my manager of distributed systems?

    Thanks for any help you can give on any of these three questions!

    -Joe

    1. Yes, as soon as you deploy the project the NSV is tranactional.  EVS is loaded by MAX when you configure the RT target and begin to operate as part of the boot sequence.

    2. you can see anything on your target rt in the DSM?

    3. Yes, NSV and EVS are persistent resets.
