    Dear All,

    i am using Runtime CODESYS Control Win V3 - X64 Version 3.5.20.40, by using CAA file library (3.5.19.0) seems not fasible to open a file n 'C:\ciao.txt' or others absolute path.

    The error on File Open is 5114 File Operation Danied..

    here below the implemented code and the windows file's properties.

    I use to implement codesys in RPI and this operation is immediate...

    Can someone help me in it??

    Thanks in advance

    Ciao, here same question

    in this post
    https://forge.codesys.com/forge/talk/Engineering/thread/4586a90290/?limit=25#d531
    i find :
    keep in mind that all files which are generated / or read should be exist in the iecfilepath
    this means:
    for Windows (Control Win as example)
    c:\ProgramData\CODESYS\CODESYSControlWinV3x64\268E8ADF\PlcLogic
    for Linux
    /var/opt/codesys/PlcLogic

    I never use codesys on windows but im sure on linux we can manipulate file only inside /var/opt/codesys/Plc Logic.
    Or you need to modify the file codesyscontrol.cfg for change path permission, but this is another history

    Buone feste !
