Profibus (Process Field Bus) is a standard for fieldbus communication in automation technology.
There are three variants of Profibus, whereas DP (decentralized periphery) is the most used:
Profibus DP for control through a central control in production engineering.
A lot of standard diagnostics options are in the foreground. Another application is the linking of "distributed intelligence", i.e. the networking of multiple controls among each.
Data rates up to 12 Mbit/sec. on twisted two-wire cables are possible.
The DP application layer was defined in three steps. The origin DP protocol (formalized in 1993) is colloquially named as "DP-V0".
The following functions are defined per level:
DP-V0 - the cyclic exchange of data and diagnostics.
Devices with this range of functions are especially used in general automation technology and machine control.
DP-V1 - the acyclic data exchange and alarm handling.
Devices that support these extensions can be found especially in process engineering.
