Freewheeling Tasks; Figure 51: Freewheeling Tasks - WAGO -I/O-IPC-C6 Manual

114 CoDeSys 2.3 Runtime Environment
Priority 11 – 15:
Applications such as long-lasting arithmetic operations and non-real-time relevant
accesses to the internal data bus, the ETHERNET, file system, fieldbus (only for
I/O-IPC with fieldbus connections) and RS-232 interface should be carried out as
tasks with the lowest priorities 11-15. The programs within a priority have no
difference in priority since each task is assigned the same computing time.

Freewheeling Tasks

If you do not undertake any task configuration, the program PLC_PRG is carried
out with the lowest priority at an interval of 10 ms. The runtime of "freewheeling
tasks" is not monitored by a CoDeSys watchdog.
11.6.2 Freewheeling Tasks
For the use of freewheeling tasks, the input field "Priority (0 ... 15)" in the figure
below has no function since it has the lowest priority in the operating system.
For the use of several freewheeling tasks, the operating system takes over their
management and assigns each one the same computing time since freewheeling
tasks are not distinguished by their priority.
