Redundant, fault-tolerant plant bus

Functionality
The plant bus connects automation systems with servers (OS server, Route Control server).
The connection to a redundant, fault-tolerant plant bus is implemented with Ethernet
communications processors (CPs) that are installed in each subsystem of the automation
system and in the servers.
A redundant, fault-tolerant plant bus is set up using two identical, separate plant bus rings
(double ring). The network components ensure unrestricted operation of the plant bus. If a
plant bus fails, communication remains possible over the second plant bus.
