<div class="markdown_content"><p>I think this is possible by handling the "after_reset" system event with a callback POU.

It was Ok</p></div>

<div class="markdown_content"><p>Hello Hasse,</p> <p>A Restart is only possible in the code of the runtime systeme. Such things are typically done in I/O driver. And must be done by the hadrware- manufacturer.</p></div>
