- Bus system
- for process and field communication with field devices from different manufacturers
- and for data communication acc. to IEC 61158/61784
- 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
- Offers openness for interfacing to standardized non-Siemens components
- 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
