​Distributed System Architecture (DSA) is the ideal solution for integrating processes when there are multiple units, control rooms or geographically distributed locations. With Distributed System Architecture, users experience a single, totally integrated system instead of several independent systems, while retaining the ability to autonomously manage each system. The result: optimum functionality and flexibility.

​Distributed System Architecture allows multiple Experion® Process Knowledge Systems (PKS) to operate as one across multiple units, sites and facilities across the enterprise. This single integrated system enables seamless global access to data, alarms, alerts, interactive operator control messages and history across groups of systems.

Configuration takes just minutes through automatic discovery of points, thus reducing engineering costs and improving system integrity. This also eliminates costly, error-prone database duplication.

DSA delivers this integration amongst multiple systems while retaining a coherent, global security scheme. Individual Experion Systems can also be operationally integrated while retaining their own engineering autonomy.

Distributed System Architecture dynamically adjusts to changing user and application demands for information. Point data, alarms, history, and operator messages are delivered only to current subscribers, and only when there is a change in status. Additional efficiencies are achieved through the transfer of information between clusters of interested users, rather than between individual users. Therefore, if multiple users are interested in the same data on another site, the request is sent only once.

These and other techniques allow Distributed System Architecture to be extremely efficient with its network usage, allowing satellite and other low bandwidth/high latency networking possibilities. DSA being a single integrated system also doesn’t require any dedicated networking and can leverage existing WAN infrastructure. Firewall friendly features allow Distributed System Architecture to adapt to existing firewall configurations to allow existing infrastructure to be used.​

​Honeywell’s patented Distributed System Architecture (DSA) technology offers users unmatched scalability by seamlessly integrating the operational data of multiple Experion systems together at the same site or across different geographical locations without additional engineering or configuration.
