The strengths of PROFIsafe have made it the market leading communication protocol for safety-related applications. Evidence of this can be seen in the more than 5 million installed PROFIsafe nodes (at end of 2015). To demonstrate the strengths of PROFIsafe, the PROFIsafe Marketing Working Group of the PNO (PROFIBUS Nutzerorganisation e. V.) has set up a live demo. Markus Kempf (Siemens) and Wolfgang Wiedemann (Murrelektronik), members of the PROFIsafe Marketing Working Group explain the advantages and performance capability of PROFIsafe using the setup with devices of various manufacturers. The PROFIsafe live demo consists of the combination of a live application and a device wall. It thus illustrates the variety of PROFIsafe products for PROFINET and PROFIBUS and their interaction. The live demo demonstrates the real-world use of safety-related communication between three fail-safe hosts of different manufacturers. It shows how three machines with different controllers can operate independently or together in a plant. An Emergency Stop or other safety functions act on just one or on multiple plant units. The functional demo shows optical and electromechanical sensors, I/O modules, fail-safe PLC, gateway, and drives. As well as the simple cabling, the entire safety functionality runs over the single cable (PROFINET/PROFIBUS/PROFIsafe).
