●
The position actual values of both measuring systems are compared for safe transmission. If
the difference is less than the set monitoring window, the value is considered safe. The safe
position actual value and the calculated safe speed value are transmitted via the PROFIsafe
profile. The part of the control which performs the safety-oriented functions can then process
these values.
●
The position actual value and the calculated speed value of the first measuring system are
directly transmitted in the unsafe process data channel. This channel is generally processed
more frequently by the control. This allows normal automation processes to access the
updated position value more frequently.
