Introduction
■
Overview
With the SIMATIC NET network components based on globally
established standards, SIMATIC PCS 7 possesses a powerful
and rugged range of products for implementing totally inte-
grated communication networks for reliable data exchange
between all system components and levels in a plant.
The SIMATIC NET products specially developed for industrial
applications provide optimum suitability for plants in all sectors.
They are matched to one another, and meet the highest indus-
trial demands, especially in areas subject to extreme influences,
such as
•
Extended temperature range
• Vibration
•
High mechanical stress
The SIMATIC NET products guarantee expandability and the
protection of investments as a result of compatible further devel-
opments, as well as uniformity from inbound logistics to out-
bound logistics and from field devices up to the Manufacturing
Execution System (MES).

Design
Incorporated in Totally Integrated Automation, the unique basis
offered by Siemens for uniform automation of all sectors in the
production, process or hybrid industries, the SIMATIC NET port-
folio ensures fast and reliable communication between the indi-
vidual systems/applications of the SIMATIC PCS 7 process con-
trol system such as:
•
Automation systems, distributed I/Os and field components
•
Engineering system, operator system and Maintenance
Station
•
SIMATIC BATCH and SIMATIC Route Control
•
Web clients and Web servers for operator control and
monitoring via Internet/Intranet as well as IT applications
Industrial Ethernet plant bus
Industrial Ethernet is used as the plant bus as well as terminal
bus for multi-user systems with client/server architecture. For
small systems, the "Basic Communication Ethernet" (BCE) inte-
grated in the SIMATIC PCS 7 Industrial Workstations permits
operation of single stations and servers on the plant bus even
without a CP 1613/CP 1623/CP 1628 communications proces-
sor.
In medium and large plants with high requirements, SIMATIC
PCS 7 applies modern FastEthernet and Gigabit technology that
combines the high availability provided by redundant electrical
and optical rings with the scalable performance provided by
switching technology and high transmission rates of up to
10 Gbps.
PROFINET
PROFINET is based on the international standards IEC 61158
and IEC 61784 and combines the advantages of the open net-
work standard, Ethernet, and the PROFIBUS fieldbus system. It
stands for maximum transparency, open IT communication, net-
work security and real-time communication down to the field
level. This makes PROFINET the basis for uniform automation
network in the plant, into which existing fieldbuses implemented
with PROFIBUS can be easily integrated.
