I have seen in the device description file that you have texts like these:
realtime priority (SCHED FIFO 66)
I was wondering when i have a realtime kernel does Codesys automatically create processes for the tasks that runs with SCHED_FIFO according to the device description?
Because when looking with ps in the linux shell I can only see two codesys processes that are SCHED_OTHER.
And I read on another forum a tip that I should schedule the two codesys processes as SCHED_RR to make Codesys run with lower Jitter... But that doesnt seem to change anything if I try It and that setting is lost when rebooting.
Is there anything you can do to try and improve the jitter? I am not having any problems at the moment but I like to know these things so that when it becomes a problem I know what to do.
