    Priority

    Defines how the CPU prioritizes tasks when multiple tasks are configured. Priority 0 ... 15 = real-time tasks, priority 16 = non-real-time task.

    Type

    Defines how the CPU executes the task, depending on the process requirements.

    Interval

    Defines the execution interval for cyclic tasks. It is usually set in milliseconds using IEC time syntax.

    Watchdog

    Monitors whether the task exceeds the allowed execution time.

    Calls

    Defines the POUs that are called and executed within the task.
