1.5.2 FSoE connection
Fail Safe over EtherCAT / FSoE
1.5.2.1 Conditions
The SM302 supports the transmission of safe information via FSoE protocol in compliance
with the "ETG.5100 S" specification, version 1.2.0, of the EtherCAT user organisation (ETG).
The standard device forwards the FSoE information to the safety module for safe
evaluation.
Note!
A safety bus system can only be operated via the upper module slot (MXI1) of
the Servo Drive 9400.
1.5.2.2 Description
Safe transmission via EtherCAT ("Fail−Safe−over−EtherCAT").
Addressing
In order that a data frame reaches the correct node, a unique FSoE target address is
required. If "FSoE" has been selected as safety bus, the safety address is at the same time
accepted as the FSoE target address. This address must match the corresponding
configuration of the safety PLC.
FSoE frame
The FSoE data are sent in the first slot of an EtherCAT data frame.
This must be observed for the hardware configuration of the safety PLC!

ESI file
The ESI file contains all information on the configuration of the EtherCAT system. This
makes the integration easy and user−friendly.
