SIMATIC NET Network Solutions

for PROFIBUS according to IEC 61158/EN 50170

Product Brief September 2001

PROFIBUS is the bus system for com-

munication in small cell networks and

with field devices. It is based on the

IEC 61158/EN 50170 European Standard,

Volume 2, PROFIBUS. In this way

PROFIBUS ensures an open system for

connecting the components of other

manufacturers that conform to the

standard.

PROFIBUS – the standard in field

installations – comprises:

· Defining the standards for the physi-

cal bus level and for access methods

(layers 1 and 2 of the ISO Reference

Model).

· Defining the user protocol and the

user interface

PROFIBUS-FMS (layer 7) for com-

munication between programmable

controllers and field devices.

· PROFIBUS-DP for fast, cyclic data

exchange with field devices.

PROFIBUS meets the requirements for

simple cabling in electrical and optical

transmission technology. This makes it

possible to cover great distances.

PROFIBUS provides connection

options for a wide range of Siemens

automation systems and third-party

systems for implementing small cell

networks.

With network components from the

SIMATIC NET

product range,

PROFIBUS networks can be set up

simply and quickly.
