Modern communication systems not only realise the deterministic transfer of control data, but also enable the transfer of safety-critical control data through the same medium. EtherCAT utilises the Safety over EtherCAT (FSoE = FailSafe over EtherCAT) protocol for this purpose.
The safe operation of machines often requires safety functions to limit speeds, directions of rotation, or axis positions. With traditional safety solutions, dangerous operating states are detected and avoided using external safety modules. However, this only serves to increase the complexity of the machine’s safety concept. In contrast, drive controllers with integrated safety functions and safety PLCs, including certified function blocks, can be used today.
The benefits of using FSoE in machine design projects are numerous, but here are five key benefits to consider...
