Honeywell Distributed System Architecture (DSA) allows multiple Experion® Process Knowledge Systems (PKS) to operate as one within a single facility, unit, and site or across the enterprise.
Previously, this level of integration could only be implemented within a single, central system. DSA enables seamless global access to points, alarms, interactive operator control messages, and history across constellations of systems, eliminating costly, error-prone performance and functionality, and database duplication or gateways.
DSA dynamically adjusts to changing user and application demands for information.
DSA employs a communications regime that results in an order of magnitude improvement in performance of network and system loading.
DSA enables full seamless management of remote systems at unmanned sites, such as stand-by regional control centers. DSA delivers integration among systems within a coherent global security scheme with absolutely no duplicate databases or redundant engineering of any kind.
DSA is experienced as a single, totally integrated system, rather than several independent systems. At the same time, each system is autonomously managed in each location. The result is an optimum combination of functionality and flexibility.
An example of a geographically super-distributed system with a wide area network connecting the individual Experion systems. The master control center accesses data from the systems at each remote site. It may or may not have its own locally connected controllers. The systems at the remote sites may also exchange information with each other.
