Process Image

4 Process Image
The 750-662/000-004 F I/O module occupies 7 data bytes in the input process
image and 5 data bytes in the output process image on the fieldbus. The secure
PROFIsafe telegrams to send and receive are stored in input bytes 0 ... ... 6 and
in output bytes 0 ... 4.
Only use process values transmitted via PROFIsafe for safety-related
applications
Process values received via communication paths other than the secure protocol
must not be used for safety-related applications.
The process image is structured according to RIOforFA
Since the process image is structured according to RIOforFA, the channel status
byte contains the "RIOforFA Qualifier."
