Validation of safety-related wireless machine control systems (NT TR 605)

NT TR 605

  • Wireless technologies are spreading also to safety-related applications. Wireless communication is realised by sending messages bit by bit from transmitter to receiver (serial mode communication). This resembles quite much the method used in field buses. There are already several field buses, which are validated to be used in safetyrelated applications.
