Section 4.1.8 System Program
3BSE 002 415R701 Rev A
4-17
4.1.8.1 Operating System
shows in more detail the internal interrelation between the processor module parts
and the operating system.
The part of the program in the operating system which is responsible for all allocation of
priority, start and supervision of the different program functions is called the kernel. It is also
responsible for that part of the data exchange between the different program modules which is
not performed in the data base.
The kernel also organizes interrupts at regular intervals for the cyclic execution, for example
from DI and communication boards and from the interval clock to activate, for example, the
interpreter.
