TwinSafe systems are created by using safety I/O terminals in conjunction with the vendor’s standard I/O terminals and DIN rail mounted controllers. When using the vendor’s TwinCat PC-based automation and control software, users can create typical safety functions such as emergency stop, safety doors and light curtains. The TwinSafe protocol enables transfer of safety-relevant data via multiple mediums. Since the compatible bus systems used do not contribute to or take away from safety aspects, already existing fieldbus systems such as Profibus or EtherCat can be used. No separate bus system is required for the safety circuits.
