Freewheeling Tasks; Figure 55: Freewheeling Tasks - WAGO -I/O-SYSTEM 750 User Manual

98 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 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.
If you do not undertake any task configuration, the program PLC_PRG is carried
out with the lowest priority at an interval of 10ms.

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.
