Network redundancy can be implemented on two levels, depending on whether you install
single or dual media. During normal operation in a single ring, the redundant switch-hub will
continue to operate without interruptions during a single network fault so there is no impact
on network operation. In the event of two simultaneous faults, the network is divided into two
isolated parts and continues to operate in this capacity. When configured with redundant
rings, the network can handle up to three faults simultaneously.

System Hardware
Operator Management Stations
During loss of an operator station, operation often encounters insufficient operator stations.
OC 6000e stations support operation, engineering, and maintenance functions from a single
workstation. Therefore, these stations are mutually redundant in function so the loss of any
station will not impair proper operation and maintenance of the system.

Controller
Controllers in Distributed Processing Stations (DPS) provide the interface with process
I/O. Control algorithms are configured by engineers through the engineering stations
and executed in the controller. Controllers can be implemented in simplex or redundant
configurations per user requirement.
