3.2 SIMATIC NET Communications Networks

SIMATIC NET is an open, heterogeneous communications system with

a variety of local area networks (LANs) providing various ranges of

performance for manufacturing and process automation in industry. It

is based on national and international standards according to the

ISO/OSI reference model.

SIMATIC NET provides the following communications networks for

different requirements (Figure 3.2):

•

Industrial Ethernet, a cell and management level network based on

IEEE 802.3 (ETHERNET).

•

PROFIBUS, a cell and field level communications network

complying with PROFIBUS (Process Field Bus, En 50 170. /1/

•

AS-Interface (based on AS-i) a communications network for the

actuator and sensor level.
