Profibus-DP presentation
The Profibus-DP (Process Fieldbus Decentralized Peripheral) is an open type
fieldbus system for industrial applications. The Profibus standard is described in
standard EN 50170.
The physical link is a simple, type A, shielded twisted pair.
Data exchange between the Master (processing unit) and the Slaves (decentralized
devices) is performed in a cyclic manner.
A maximum of 32 Slaves can be connected to a bus segment. To increase the
maximum number of Slaves possible, repeaters must be installed in order to create
new bus segments.
The repeaters also provide galvanic isolation of the bus segments.
The total number of slaves must not exceed 126.
The bus must be fitted with a line terminator at each end of each segment created.
