Profibus

There’s a name for successful fieldbus communication: PROFIBUS

PROFIBUS portfolio from Siemens

With well over 60 million installed nodes, PROFIBUS is the leading fieldbus for industrial automation on the world market. The success of PROFIBUS is no coincidence. The benefits of this universally usable, open, and rugged fieldbus system for data communication according to IEC 61158/61784 are valued in all industries. Siemens offers you a comprehensive product and system portfolio.

There are two variations of PROFIBUS in use today:

  • PROFIBUS DP (Decentralised Peripherals) is used to operate sensors and actuators via a centralised controller in production (factory) automation applications. The many standard diagnostic options, in particular, are focused on here.
  • PROFIBUS PA (Process Automation) is used to monitor measuring equipment via a process control system in process automation applications. This variant is designed for use in explosion/hazardous areas (Ex-zone 0 and 1). The Physical Layer (i.e. the cable) conforms to IEC 61158-2, which allows power to be delivered over the bus to field instruments, while limiting current flows so that explosive conditions are not created, even if a malfunction occurs.
