Post by voffi on About Codesys Task Executions ^{CODESYS Forge talk (Post)}
A task in CODESYS normally is a task of the underlying operating system. If your os is preemptive and the sheduler is configured accordingly a CODESYS task will be preemptive too.

Post by scarter on Import/Export PLCOpen xml Task Configuration ^{CODESYS Forge talk (Post)}
I'm Having the same issue. If I highlight PLC Logic and import it erases everything else and replaces the Task config. If I highlight the Application I get the same result. Simple manual fix is click and drag the task config onto the origional Application, and delete the second one. Easy fix but not the expected result of importing task config.
