Introduction
PROFIBUS (
Pro

Fi
eld
Bus
) is a vendor-independent, open fieldbus
standard for a wide range of applications in manufacturing, process and building
automation. Vendor independence and openness are guaranteed by the
PROFIBUS standard EN50170-2. With PROFIBUS, devices of different
manufacturers can communicate without special interface adjustments.
The PROFIBUS family consists of three compatible versions:
PROFIBUS-DP
DP
stands for
D
ecentralised
P
eriphery. It is optimised for high speed and
low-cost interfacing, especially designed for communication between
automation control systems and distributed I/O at the device level.
PROFIBUS-PA
PA
stands for
P
rocess
A
utomation. It permits sensors and actuators to be
connected on one common bus line even in intrinsically-safe areas. It permits
data communication and power supply over the bus using 2-wire technology
according to the international standard IEC 1158-2.
PROFIBUS-FMS
FMS
stands for
F
ieldbus
M
essage
S
pecification. This version is the
general-purpose solution for communication tasks at a higher level. Powerful
services open up a wide range of applications and provide great flexibility. It can
also be used for extensive and complex communications tasks.
PROFIBUS-DP and PROFIBUS-FMS use the same transmission technology
and a uniform bus access protocol. Thus, both versions can be operated
simultaneously on the same cable. However, FMS field devices cannot be
controlled by DP masters or vice versa.
Caution
It is not possible to exchange one of these family members by another family
member. This will cause faulty operation.
The remainder of this Operation Manual only describes PROFIBUS-DP.
