Welcome to PROFIBUS

PROFIBUS is the powerful, open and rugged bus system for process and field communication in cell networks with few stations and for data communication in accordance with IEC 61158/EN 50170. Automation devices such as PLCs, PCs, HMI devices, sensors or actuators can communicate via this bus system. The IEC 61158/EN 50170 standard makes allowance at the same time for the future of your investments since existing plants can be expanded using components that conform to the standard. PROFIBUS is part of Totally Integrated Automation (TIA), the uniform, integrated product and system range from Siemens for efficient automation of the entire production process – for all sectors of industry.

Possible uses

PROFIBUS can be used, for example, for the following applications:

• Factory automation
• Process automation
• Building automation

Different PROFIBUS versions are available for the various fields of application:

• Process or field communication
  - PROFIBUS DP (for fast, cyclic data exchange with field devices)
  - PROFIBUS PA (for intrinsic safety applications in process automation)
• Data communication
  - PROFIBUS FMS (for data communication between programmable controllers and field devices )

SIMATIC NET products are particularly suitable for use in industry. For implementing Profibus networks, SIMATIC NET offers the required network components and system interfaces for connecting S7 and PC/IPC.

• Network components
  PROFIBUS networks can be implemented quickly and easily using the network components from the SIMATIC NET ® product range. Various cables and connections are available depending on application. In the case of copper cables, in particular, FastConnect stripping technology ensures fast and reliable cabling.
  
  
• System connections
  SIMATIC S7 and PG/PC are connected via communications processors - this relieves the CPU of communications tasks.
