Overview

With the SIMATIC NET network components based on globallyestablished standards, SIMATIC PCS 7 possesses a powerful andrugged range of products for implementing totally integratedcommunication networks for reliable data exchange between allsystem components and levels in a plant.

The SIMATIC NET products specially developed for industrialapplications provide optimum suitability for plants in all sectors.They are matched to one another, and meet the highest industrialdemands, especially in areas subject to extreme influences, suchas:

• Extended temperature range

• Vibration

• High mechanical stress

The SIMATIC NET products guarantee expandability and the protectionof investments as a result of compatible further developments, aswell as uniformity from inbound logistics to outbound logistics andfrom field devices up to the Manufacturing Execution System(MES).

Design

Incorporated in Totally Integrated Automation, the unique basisoffered by Siemens for uniform automation of all sectors in theproduction, process or hybrid industries, the SIMATIC NET portfolioensures fast and reliable communication between the individualsystems/applications of the SIMATIC PCS 7 process controlsystem such as:山东西门子低压电器总代理商

• Automation systems, distributed I/O 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 monitoringvia Internet/Intranet as well as IT applications

Industrial Ethernet is used as the plant bus as well as terminalbus for multi-user systems with client/server architecture. Forsmall systems, the "Basic Communication Ethernet" (BCE) integratedin the SIMATIC PCS 7 Industrial Workstations permits operationof single stations and servers on the plant bus even without aCP 1623/CP 1628 communications module.

In medium and large plants with high requirements, SIMATICPCS 7 applies modern FastEthernet and Gigabit technology thatcombines the high availability provided by redundant electrical andoptical rings with the scalable performance provided by switchingtechnology and high transmission rates of up to 10 Gbps.

PROFINET is based on the international standards IEC 61158 andIEC 61784 and combines the advantages of the open networkstandard, Ethernet, and the PROFIBUS fieldbus system. It stands formaximum transparency, open IT communication, network security andreal-time communication down to the field level. This makesPROFINET the basis for uniform automation network in the plant,into which existing fieldbuses implemented with PROFIBUS can beeasily integrated.

Example of PROFINET communication in the SIMATIC PCS 7 processcontrol system

In the context of the SIMATIC PCS 7 process control system,PROFINET mainly focuses on communication between the automationsystems (controllers) and the process I/O.

PROFIBUS has become established as sturdy and reliablecommunications medium for connecting intelligent distributed I/Odevices, transmitters and actuators to the controller level of theSIMATIC PCS 7 process control system. The universal, openfieldbus corresponds to the international standards IEC 61158and IEC 61784.

Integration of PROFIBUS PA and FOUNDATION Fieldbus H1

PROFIBUSDP山东西门子低压电器总代理商

PROFIBUS DP is both a system bus and an open communicationsystem, and is designed for moderate transmission rates and shortresponse times. It is therefore optimally suitable for the controlof the following devices:

• Directly connected field devices, e.g. drives, motor starters,analyzers, process controllers, or panels

• Distributed I/O devices such as the SIMATIC ET 200M,SIMATIC ET 200iSP and SIMATIC ET 200pro remote I/Ostations

• Transmitters and actuators on a seamlessly integratedPROFIBUS PA fieldbus or FOUNDATIONFieldbus H1山东西门子低压电器总代理商

Since it also supports the transmission of the HART protocol, HARTfield devices can also be integrated in a PROFIBUS DPcommunication network.

PROFIBUS PA and FOUNDATIONFieldbus H1

In addition to the direct connection of transmitters and actuatorsincluding power supply via the communication medium, the highinformation content of the communication as well as the diagnosticoptions are also of importance for the automation of industrialprocesses that frequently take place in corrosive, harmful, andhazardous environments.

Both the PROFIBUS PA fieldbus and the FOUNDATIONFieldbus H1 meet these requirements. Both are optimallysuitable for directly integrating actuators and sensors inoperating environments up to Ex zone 1/21 or 0/20 into the processsystem.

Their physical bus characteristics are based on the MBPtransmission technology (Manchester Coded; Bus Powered) and arelargely identical according to IEC 61158. Both fieldbuses canbe integrated seamlessly in the SIMATIC PCS 7 process controlsystem using PROFIBUS DP as link.

PROFIBUS PA and FOUNDATION Fieldbus H1 thus profitequally from the higher-level PROFIBUS architecture.
