Overview

Design山东西门子低压电器总代理商

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 integrated 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 industrial demands, especially in areas subject to extreme influences, such as:

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

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 portfolio ensures fast and reliable communication between the individual systems/applications of the SIMATIC PCS 7 process control system such as:山东西门子低压电器总代理商

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) integrated in the SIMATIC PCS 7 Industrial Workstations permits operation of single stations and servers on the plant bus even without a CP 1623/CP 1628 communications module.

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 is based on the international standards IEC 61158 and IEC 61784 and combines the advantages of the open network standard, Ethernet, and the PROFIBUS fieldbus system. It stands for maximum transparency, open IT communication, network 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.

Example of PROFINET communication in the SIMATIC PCS 7 process control system

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

PROFIBUS has become established as sturdy and reliable communications medium for connecting intelligent distributed I/O devices, transmitters and actuators to the controller level of the SIMATIC PCS 7 process control system. The universal, open fieldbus corresponds to the international standards IEC 61158 and IEC 61784.

Integration of PROFIBUS PA and FOUNDATION Fieldbus H1

PROFIBUS DP山东西门子低压电器总代理商

PROFIBUS DP is both a system bus and an open communication system, and is designed for moderate transmission rates and short response times. It is therefore optimally suitable for the control of the following devices:

Since it also supports the transmission of the HART protocol, HART field devices can also be integrated in a PROFIBUS DP communication network.

PROFIBUS PA and FOUNDATION Fieldbus H1

In addition to the direct connection of transmitters and actuators including power supply via the communication medium, the high information content of the communication as well as the diagnostic options are also of importance for the automation of industrial processes that frequently take place in corrosive, harmful, and hazardous environments.

Both the PROFIBUS PA fieldbus and the FOUNDATION Fieldbus H1 meet these requirements. Both are optimally suitable for directly integrating actuators and sensors in operating environments up to Ex zone 1/21 or 0/20 into the process system.

Their physical bus characteristics are based on the MBP transmission technology (Manchester Coded; Bus Powered) and are largely identical according to IEC 61158. Both fieldbuses can be integrated seamlessly in the SIMATIC PCS 7 process control system using PROFIBUS DP as link.

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