• Bus system
  • for process and field communication in cell networks with a small number of stations and with field devices
  • and for data communication acc. to IEC 61 158/EN 50 170
• Offers openness for interfacing to standardized non-Siemens components
  • PROFIBUS – the fieldbus standard in production and process engineering comprises:
  • specification of the standards for the physical characteristics of the bus and the access procedure
  • specification of the user protocol and the user interface
• Process or field communication
  • PROFIBUS DP for fast, cyclic data exchange with field devices
  • PROFIBUS PA for applications in process automation and in the intrinsically safe area
• Data communication
  • PROFIBUS FMS for data communication between programmable controllers of different manufacturers
