1. Experion PKS system and hardware architecture 1.1 Experion PKS system The Experion PKS Process Knowledge System is Honeywell’s latest generation of process automation system. Experion PKS integrates personnel with process control, operations, and asset management. Experion PKS offers users capabilities that are far superior to those of distributed control systems, including embedded decision-support and diagnostic technologies that provide decision-makers with the information they need ； Security components ensure a secure environment for the system **within the main control system, thereby enhancing the system’s security and reliability. The architecture of Experion PKS is shown in the figure below. Features of the Experion PKS system: (1) Global database: The information required by the control processor and the monitoring system server can be entered once, eliminating the need to configure different databases at various levels separately. (2) Honeywell HMI Web technology: HMI Web technology is a human-machine interface based on a Web structure, capable of integrating process control data and business application data. HMI Web uses HTML (HyperText Markup Language) as the basic format for its display interface, and provides the capability to access process screens via the IE browser. (3) Global online documentation: It enables users to quickly access Knowledge Builder, which contains system-related information, providing them with online assistance and technical support, thereby avoiding the inconvenience of having to search for extensive materials in various places. (4) Real-time Database (RTDB): It adopts a client/server architecture; under normal conditions, the server provides the required real-time data to the clients, but in the event of a server failure, certain clients can directly retrieve the necessary real-time data from the controller. (5) Advanced system framework: includes a complete basic framework, an alarm/event management subsystem, a report subsystem that is easy to configure, extended historical data acquisition, and various types of system standard trends. (6) Good openness: Supports the most advanced open technologies and standards. (7) Strict security: Multiple channels ensure the security of the system.
