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.
