PROFIBUS

PROFIBUS

...is the world's most successful fieldbus with 56.1 million devices installed by the end of 2016 with 10.6 million of these in the process industries.

Utilizing a single, standardized, application-independent communication protocol, PROFIBUS supports fieldbus solutions both in factory and process automation as well as in motion control and safety-related tasks.

PROFIBUS is standardized in IEC 61158 – the foundation has therefore been laid for interoperability and compatibility. Furthermore the PROFIBUS PA profile allows the smooth cooperative working of process devices on the bus. The current PROFIBUS PA version V3.02 includes many functions, which make the handling of field devices even easier, e.g. in case of a device exchange.

When a field device is exchanged the new device automatically takes over the role of the predecessor device – therefore a device exchange can be carried out easily and without interruption of the system operation.
This automatic adaption is also possible with devices of different generations.

This means that standardization offers more flexibility and no limitation in your choice of supplier. Indeed, in the meanwhile there is a vast range of devices available that can be combined in almost any way. A focus on only one manufacturer is no longer given.
Even replacing devices later on is absolutely easy and with PROFIBUS new devices are always backward-compatible.
