<div class="markdown_content"><p>Hello and sorry for gravedigging,</p> <p>but I was just wondering the same(ish) thing:<br/> Is there a way in Codesys 3.5 with the 3.5.14.20 Pi Runtime to create tasks<br/> that will only be called once during startup/shutdown of the PLC?</p> <p>In my program I am opening a file in the local filesystem and<br/> if I stop or logout the program with a file handle opened<br/> it will raise an exception and I will have a bad time.</p> <p>Therefore I was thinking that I could write a task which would<br/> close any opened filehandles in order to shutdown gracefully.</p> <p>Thanks in advance!</p></div>

<div class="markdown_content"><p>Is this possible w/ the r-Pi?</p> <p>On another plc in CodeSys v3.1, I could configure task type = External, event = on_Start. But I don't have these options for the r-pi, v3.5. </p> <p>Any way to do this? Is this a difference specific to ver 3.5 of CodeSys, or the r-Pi, or both?</p></div>
