There’s a name for successful fieldbus communication: PROFIBUS

With well over 64 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.

PROFIBUS portfolio from Siemens

Network components

Transmission components for electrical and optical networking

The PROFIBUS portfolio from Siemens offers you an extensive range of network components for electrical and optical transmission technology. Using suitable cabling technology in the form of the PROFIBUS FastConnect system, the PROFIBUS cables for electrical and optical networks can be quickly, easily, and correctly assembled on site. The transition between electrical and optical networks can easily be implemented using PROFIBUS OLMs (Optical Link Modules), as well as the configuration of optical networks in linear, star, or redundant ring topologies.

Connecting systems

Fast fieldbus communication with PROFIBUS ...

… for SIMATIC S7

The PROFIBUS communications processors (CPs) for the SIMATIC S7 controllers open up further use cases, thanks to additional functions such as fiber optic as far as the terminal device. They also enable the flexible expansion of SIMATIC S7 controllers with further communication interfaces for PROFIBUS as required and in this way lighten the load on the CPU.

… for PG/PC

The system connections for PG/PC include, for example, SIMATIC NET PC communications processors (CPs) for PCI, PCI Express, and USB interface, as well as CPs with or without an internal microprocessor. The PC adapter for commissioning and diagnostics makes it possible to connect PCs and notebooks to PROFIBUS via a USB interface and to the MPI interface of SIMATIC S7. Plus the SIMATIC NET PC software offers a wide range of products for industrial communication and features the latest PC technology trends.

Distributed I/O

Customized distributed automation systems with PROFIBUS

SIMATIC ET 200 is a multifunctional, modular, and precisely scalable system for distributed automation. All system components can be integrated in the automation system via PROFIBUS.

Communication modules

Intelligent data management with industrial identification

Whether in production or logistics, communication modules allow you to connect our SIMATIC Ident systems (RFID and optical identification systems) to SIMATIC controllers, PC-based systems, or controllers from third-party suppliers. Various powerful communication modules (ASMs) are available for integrating the SIMATIC RFID and SIMATIC MV identification systems in SIMATIC, SINUMERIK, and SIMOTION, or in the PROFIBUS, PROFINET, and EtherNet/IP bus systems.

Network transitions

Always the right network transition – for unlimited communication

Whether you‘re connecting the Industrial Ethernet, PROFIBUS, AS-Interface, or Industrial Wireless LAN, Siemens has your industry-proven network transition solution. We offer tailor-made products for every network type and can provide you with the optimal basis for company-wide, integrated, and unlimited communications, thanks to reliable network transitions.

PROFIBUS routers

Protected remote access to plants and machines with PROFIBUS

The compact PROFIBUS/MPI router SCALANCE M804PB permits the cost-effective and secure connection of machines and plants, e.g. SIMATIC S7-300/S7-400, to Ethernet networks. This also makes them accessible via remote access, for example for remote maintenance. The integrated firewall and VPN security functions increase protection against unauthorized access and improve the security of data transmission. The routers also enable you to access PROFIBUS/MPI programmable controllers via your local Ethernet interface.
