TwinSAFE | Open and scalable safety solution

The TwinSAFE integrated safety solution represents the consistent continuation of the open and PC-based control philosophy from Beckhoff. Due to their modularity and versatility, the TwinSAFE terminals fit seamlessly into the Beckhoff control system. The I/O components are available as Bus Terminals, EtherCAT Terminals, EtherCAT plug-in modules and EtherCAT Box modules.

With the fieldbus-neutral safety protocol (TwinSAFE/Safety over EtherCAT), TwinSAFE devices can be integrated into any desired fieldbus system. To this end, the IP 20 TwinSAFE Bus Terminals are integrated into existing stations with K-bus or EtherCAT or used directly in the machine as IP 67 modules. These safety I/Os provide the interfaces to safety-relevant sensors and actuators.

The possibility to transmit safety-relevant signals over a standard bus system creates significant advantages in terms of planning, installation, operation, maintenance, diagnostics and costs.

The safety-relevant application is configured or programmed in TwinCAT software. This application is then transmitted over the bus system to a TwinSAFE Logic terminal. These logic terminals are at the heart of the TwinSAFE system. All safety devices in an installation communicate with this logic terminal. Due to the enormous flexibility of the system, however, several TwinSAFE Logic terminals can be operated simultaneously in one network.
