System Architecture
Control system failure will likely result in the loss of production and equipment damage.
This makes control system reliability an extremely important consideration when choosing
a control system. The OC 6000e DCS has been engineered with special attention to diagnostic
and redundancy features. The results are reduced downtime, improved system availability,
enhanced control reliability, and uninterrupted system access.

Control, I/O, operator stations, engineer stations, data management, and gateway functions
are distributed on a three-tiered Ethernet network to ensure system integrity and timely data
transmission. Each node in the system is autonomous and yet closely integrated with its peers.
The architecture distributes risk so the loss of any one component does not affect the rest of
the system. For example, if a single controller fails, operation in other areas of the plant will be
uninterrupted.

The distributed architecture also gives users greater flexibility in system installation and
space utilization. Having the flexibility to distribute control, I/O, and HMI functions to different
areas of the plant allows users to optimize available space. There is no need to allocate a
large central area for the DCS installation.

System Network
To minimize the probability of total communication failure, the OC 6000e DCS has a three level
network; namely Plant Data Highway (PDH), Unit Data Highway (UDH), and I/O Network (I/ONet).
Such network structure reduces extraneous network traffic, enhances network performance,
and improves network reliability.

and improves network reliability.
Plant Data Highway connects Operator Management stations for fast and effective data
transfer of non-real-time files and print sharing. This improves overall network performance
by offloading non-critical communication from Unit Data Highway.

by offloading non-critical communication from Unit Data Highway.
Unit Data Highway connects the Operating and Control levels of the system. UDH provides
superior reliability and availability between the operator and control layers through its
double-ring high-speed Ethernet backbone, allowing uninterrupted access to real-time
process information, alarms, and events.

The redundant Process I/O Network establishes a high-speed data transmission between
DCS and Remote I/O stations over a distance of up to two kilometers. It uses a 100 MB
Ethernet, is compatible with standard Ethernet devices per IEEE802.3, and supports
IEEE1588 Precision Time Protocol. The media can be fiber or twisted pair.
