PROFIBUS provides the transfer of safe information via the PROFIsafe protocol according to
the "PROFIsafe - Profile for Safety Technology" specification, Version 2.0.
 The PROFISafe messages are sent in the first slot of a PROFIBUS telegram.
 In the PROFIsafe messages, one bit each is used for the control of a certain safety
function.
 The structure of the PROFIsafe messages is described in the PROFIsafe profile.
 The length of the PROFIsafe message is 8 bytes.
Starting PROFIBUS/PROFIsafe in the Inverter Drive 8400 protec
Inverter Drives 8400 protec PROFIBUS are available in two designs – with or without safety
option SO20/SO30.
Sequence: If safety option SO20/SO30 PROFIsafe is activated, the use of the safety option
is supported by the master.
 The PRM and CFG data are sent by a PROFIBUS master to establish data exchange. The
data may contain safety data and general PROFIBUS data.
 Exclusive exchange of PROFIBUS data (parameter and process data) is always possible.
 If PRM data and PROFISafe messages are sent by the master, safety option SO20/SO30
must be active.
 The PRM data are checked by the safety option.
 In the master, safety data must always be assigned to the first slot (slot 0).

Note!
Transmission of safe information via the PROFIsafe protocol is only possible
when a version with an integrated safety system is used.
