Introduction to PROFIBUS

The Purpose of PROFIBUS
PROFIBUS (PROcess FIeldBUS) is an open fieldbus standard for a wide
range of applications in manufacturing, processing and building automation.
The Standard, IEC 61158 (Industrial communication networks), to which
PROFIBUS adheres, guarantees vendor independence and transparency of
operation. It enables devices of various manufacturers to intercommunicate
without having to make any special interface adaptations.
1-3-2
What is PROFIBUS DP
PROFIBUS DP (for Decentralized Periphery) is a variant optimized for high
speed and low-cost interfacing. It is specially designed for communication
between automation control systems and distributed I/O at the device level.
PROFIBUS DP uses the same transmission technology and uniform bus
access protocol as PROFIBUS FMS (for Fieldbus Message Specification).
Consequently, both versions can be operated simultaneously on the same
bus. DP field devices, however, cannot be controlled by FMS masters and
vice versa.
!Caution
It is not possible to exchange a PROFIBUS DP device or master for a PROFI-
BUS FMS device or master. This will cause faulty operation.
