The integrated TwinSAFE safety solution is the logical continuation of the open, PC-based Beckhoff control philosophy. Due to their modularity and versatility, the TwinSAFE components fit seamlessly into the EtherCAT plug-in module system accordingly. A large number of TwinSAFE-capable EtherCAT plug-in modules are available for securely recording, processing and outputting safety-relevant signals.
In terms of technology, the EJxxxx EtherCAT plug-in modules are usually based on the ELxxxx EtherCAT Terminals with matching name. This allows initial tests to be carried out with EL terminals, while the corresponding EJ module on the signal distribution board is used in subsequent series production.
