Distributed Focussed Availability

Distributed and Redundant Systems Architectures

Any automation system component may fail, usually at an inconvenient time. Whenever a failure happens, some part of the operation will be affected.  What and for how long depends on the way in which the automation system is arranged.  This post covers two methods of arrangement.  Distributed on the one hand, where the automation functionality required for different parts of the plant is distributed with the plant. Redundant on the other hand, which centralizes functionality and provides high availability through the provision of a duplicate backup system. Invensys provides both redundant and distributed RTU types to cover many different forms of remote automation architecture.
