but I was just wondering the same(ish) thing:
Is there a way in Codesys 3.5 with the 3.5.14.20 Pi Runtime to create tasks
that will only be called once during startup/shutdown of the PLC?
In my program I am opening a file in the local filesystem and
if I stop or logout the program with a file handle opened
it will raise an exception and I will have a bad time.
Therefore I was thinking that I could write a task which would
close any opened filehandles in order to shutdown gracefully.
Thanks in advance!
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
Task Configuration - System Events - Add Event Handler - Select event (PrepareStart, PrepareShutdown, etc.) - enter name for new (not existing!) function - add implementation.

Is this possible w/ the r-Pi?
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.
Any way to do this? Is this a difference specific to ver 3.5 of CodeSys, or the r-Pi, or both?
