Hello,
can somebody help me with this sporadic error? How to find the source of this error?
it just comes from nowhere and haunts :)

An invalid pointer (either because it is 0 or points outside the memory reserved to the program) is being dereferenced. Track down pointers or interfaces that you have in code and check them - you should also be wary of mixing online change and pointers.

This was sort of what I was suspect of but couldn't find any firm documentation on what caused the error. I think I may have resolved my issue but for a long time I thought it was random. Thank you! 😄

Hello
i have found the reason why it was happening. i have used an array of ints of dimensions [1..x].
It never happened since i resize array to [0..x], though i never used first element.

hi,
you could have found this well with the POU's for implicit checks. (if it was not located somewhere in the init code)
