    Hi all

    I am totally new to Codesys.

    I have PC with runtime 3.5.14 running

    I have a structure declared as GLOBAL PERSISTENT RETAIN in the code (see attach).

    My problem is that sometimes, if I change the value of the elements of this structure during runtime, after a normal power cycle of the machine I sometimes find that the variables have still the old value.

    Is there a limit of size of persistent/retain data dimension?

    The structure is about 4000 word.

    Should I find any file with the persistent data stored?

    Someone can help?

    thank you

    IDK why you lost values but about the limit, when you compile, you should have the information about the memory remaining.
