Safety over EtherCAT - TwinSAFE

The Beckhoff EtherCAT safety products use the TwinSAFE protocol, which is transported as part of the data within the EtherCAT datagrams. The TwinSAFE protocol is basically independent of the communication channel and has its own error detection mechanisms.

In the EtherCAT system an EL6900 logic terminal deals with the safety functions and transfers data to the input and output terminals (EL1904, EL2904) via the TwinSAFE protocol.

For the application and commissioning, the corresponding device documentation and a TwinSAFE application manual are accessible in the Download section on the Beckhoff website.
