the Ethernet network
Contents of this chapter
This chapter contains on overview of the Ethernet network and the FSPS-21 module.
Module overview
The FSPS-21 is an option module for ABB Drives drive families ACS880, ACS580 and
ACS380 which enables the connection of the drive to an Ethernet network and a safety
PLC.
The intended use of the FSPS-21 safety option module is to safely stop the PDS(SR) (VSD,
drive). The module provides two safety functions, STO and SS1-t, which are activated via
PROFIsafe over PROFINET. It is also possible to use the module to control the PDS(SR)
over PROFINET.
Through the FSPS-21 module you can:
• start and stop the drive and reset drive faults
• give speed or torque reference to the drive
• read drive status word bits
• write to drive control word bits
• perform safety functions
The protocol used to access these functionalities over the Ethernet is:
• PROFINET IO – Communication protocol
• PROFIsafe over PROFINET IO
The module supports 10 Mbit/s and 100 Mbit/s data transfer rates and automatically detects
the data transfer rate used in the network.
The FSPS-21 module supports two safety functions which are activated from a safety PLC:
