6.5.2.3 Parameterization for PROFIsafe
When using the PROFIsafe, the protocol requires specific safety parameters (F-parameters) to be sent from F-host to F-device. These
parameter values must be set to the drive via the MCT-10 safety tool and to F-host via its configuration tool. During start-up, the values
on the F-host are transmitted to the drive, and the drive checks the values against the values on the drive. The values configured to F-
host and F-device must be the same for the safety communication to start.
The safety layer starts whenever the communication channel (PROFINET) is communicating cyclically. An unsuccessful initialization of
the PROFIsafe protocol does not have an effect on the PROFINET cyclic communication. The PROFINET cyclic communication can be
used to read diagnostic information if the PROFIsafe parameterization fails.
