PROFINET enables the transfer of safe information via the PROFIsafe protocol in accordance with
the "PROFIsafe - Profile for Safety Technology" specification, version 2.0.
• The PROFIsafe message is sent in the second slot of a PROFINET frame.
• One bit of the PROFIsafe data is always used to control specific safety functions.
• The structure of the PROFIsafe data is described in the PROFIsafe profile.
• If the SM301 safety module is used, the length of the PROFIsafe data (also called PROFIsafe
message) always is 8 bytes.
• If the SM302 safety module is used, the length of the PROFIsafe data (also referred to as the
PROFIsafe message) is always 16 bytes (from SW version 3.00 onwards).
• The Servo Drive 9400 forwards the PROFIsafe message to the safety module for a safe
evaluation.
 Note!
A safety bus system (PROFIsafe) can only be operated via the upper module slot (MXI1)
of the Servo Drive 9400.
