    Of course its an option, but I don't need it to be that fancy

    just want to save ten variables to a file, and on "first scan" read the variables from the file.

    /U

    This is very easy with OsCat Network Library. Network Library has file system Function blocks.

    There are include demo programs with the library. Here a link to latest version.

    Hi,

    thanks jzhvymetal, I would recommend to use the versions from CODESYS Store,
    namespaces are registered etc... and aditional advantage you get a notification in package manager if an update is availabe.

    OSCAT BASICOSCAT NETWORKOSCAT BUILDING

    are available.

    urbanlarsson,

    I only have the structure text demo program that was included inside the library. I can attach them if you want. If you install the package you should be able to see them in the demo directory of the library.

    I have updated the libraries can someone update the packages? Plus my network library uses the new CoDeSys 3 libraries. The latest are as follows:

    Updated Network Library 1.30
    Updated Basic Library 3.33

    jzhvymetal, please post the demo for me.

     
  • urbanlarsson - 2015-02-02

    jzhvymetal, if you could, I'll gladly want you to post the demos.

    Also, i downloaded the oscat files from codesys-store, and i got network v1.2.1 not 1.3 as you was speaking of?
