    Hi

    I see there is a log for the device (RPI). Is there any way to write to the same log location or is this dedicated for the device only information.

    Thanks

    Thanks Edwin

    I just have a couple of questions:

    Does this log information get stored in a file?

    If the RPI reboots, will this information be rewritten?

    What is "Offline-Logging"

    Much appreciated!

    Hi,

    by Default it is a 'ring-buffer' (alive as Long the runtime runs)
    you could activating to write the log file to the runtime Directory
    by uncommend the following section in /etc/CODESYSControl.cfg:
    (restart plc is needed after doning this)

    ->remove the ';' to activate:

    [CmpLog]
    ;Logger.0.Name=StdLogger
    ;Logger.0.Enable=1
    ;Logger.0.MaxEntries=100000
    ;Logger.0.MaxFileSize=500000
    ;Logger.0.MaxFiles=3
    ;Logger.0.Backend.0.ClassId=0x0000010B
    ;Logger.0.Backend.1.ClassId=0x00000104
    ;Logger.0.Filter=0xFFFFFFFF

    the you
    BR

    Hello!

    I have a little problem with your example project.
    I tried to make a status message with:

    stdLogger.AddLogEntry(CmpLog.LogClass.LOG_USER_NOTIFY, Errors.ERR_FAILED, 0, 'server started');

    but I only got the message "LOGGING BUFFER OVERFLOW;LOG MESSAGE DISMISSED" in the log file.
    Maybe anyone can help me?

    Best regards,
    Samuel
