￭ System overview
This figure shows an overview of a safety PLC that is connected to the ACS380 drive via
the PROFIsafe communication bus.
The FSPS-21 module is installed on the ACS580 drive. The safety PLC is connected to the
FSPS-21 module. The safety PLC activates safety functions via the PROFIsafe
communication bus.
The PROFIsafe protocol secures the whole path from the location where a safety signal
originates to the location where it is processed and vice versa.
The safety PLC sends PROFIsafe messages (frames) to the FSPS-21 module extracts the
frame from the PROFINET communication. The FSPS-21 module reads and interprets the
PROFIsafe messages and performs the required actions. The FSPS-21 module sends
PROFIsafe messages back to to the safety PLC.
The term PROFIsafe F-Output data refers to the application-specific user data in the frames
that are transmitted to the FSPS-21 module (F-Device) from the safety PLC (F-Host). The
term PROFIsafe F-Input data refers to the application-specific user data in the frames that
