OS redundancy

■Overview

Client

•A SIMATIC PCS 7 Single Station Redundancy programming package is required to design redundant OS single stations. This contains:

-OS Software Single Station

-Software WinCC/Redundancy (in each case for two OS single stations)

-RS 232 cable connector for optimization of internal commu- nication between the two OS single stations.

							• A SIMATIC PCS 7 Server Redundancy programming package
							is required to design redundant OS servers. This contains:
5		OS-LAN (Ethernet), ring 1		OS-LAN (Ethernet), ring 2			- OS Software Server
							- Software WinCC/Redundancy (in each case for two
							OS servers)
							- RS 232 cable connector for optimization of internal server-
							server communication.
							A separate Ethernet connection can be used instead of the serial
						Redundant servers	RS 232 connection for optimization of internal communication
							between the two redundant stations (OS single
							stations/OS servers). This is an alternative e.g. with larger dis-
							tances between the stations or if the COM interface is required
							elsewhere.
							An optical or electrical connection can be used depending on
							the environmental conditions and the distance between the re-
			Redundant Industrial Ethernet				dundant stations, e.g. up to 100 m per crossover network cable
							with RJ45 connectors. For further information, refer to the Man-
			plant bus (double ring)
							ual "SIMATIC PCS 7 V7.0 fault-tolerant process control systems";
							for appropriate cable material and further accessories, refer to
							Catalog IK PI (Industrial Communication).
							What further components are required depends on the plant ar-
					AS 412H/		chitecture. The design of the plant bus and terminal bus
							(OS-LAN) is of particular importance, as well as the type and
					AS 414H/		number of subordinate automation systems. The maximum re-
					AS 417H
							quirements are determined by the redundant configuration
	OS redundancy shown in a client/server architecture with high availability						shown in the figure with a fault-tolerant automation system and
							two redundant rings each for the plant bus and terminal bus.
	OS single stations and OS servers can have a redundant design
	if necessary:
