Porting PROFIsafe to the application
Safe position detection is based on three signals:
■ Coarse position
■ Redundant inverted coarse position
Fail-safe principles: Two channels and diversity
■ CRC via the redundant coarse position
Plausibility check
Before these safe signals can be transferred from the
SIMOTION controller to the F-CPU, you have to port the
PROFIsafe profile to the relevant application.
This is why the error detection measures are ported from
PROFIsafe to the communication between the SIMOTION controller
and the F-CPU.
