December 15, Version 1. Experion PKS optimizes work processes, improves routine maintenance efficiencies, and releases personnel from manual processes. Capturing and managing untapped process knowledge in a single Process Knowledge Solution?
These technologies fully integrate with existing Honeywell honeywel, including TPS,? FSC, and the PlantScape system. Experion PKS The Next Generation Process Knowledge System integrates powerful knowledge-driven decision support and diagnostic tools, providing information where and when it is needed.
This revolutionary system approach unifies business, process, asset, and safety management to: The honeywlel is improved operating profit, capital cost and cash flow.
Delivering a robust, scalable, plantwide system, Experion PKS connects your operations staff with the latest automation technology as well as with each other. Built on a rock-solid foundation of process control and safety system knowhow, this next-generation system provides unprecedented connectivity through all levels of process and business operations. This is a truly collaborative production and safety management solution. By unifying the plant-wide architecture, Experion PKS allows you to make the right product at the right time, optimize and automate, increase workforce effectiveness, and increase availability of resources while reducing incidents.
Rather than taking the narrow instrument-centric approach that informs you only when there is a need to replace a valve or perform maintenance, Experion PKS establishes a broad, processcentric view of your plant operations by focusing on the impact to operational objectives, not only the replacement of EP Version 1.
This is the key to optimizing performance. Architecture Overview Experion PKS comprises many different integrated hardware and software solutions depending upon the needs of the installation. Figure 1 is a representation of many of the possible nodes that can be utilized in an Experion PKS architecture. Note that the architecture is highly scalable and not all nodes are necessary or required.
The Functional Description section of this document provides technical details about the standard functionality of the Experion PKS Server.
These are identified in the Options section of this document and include technical details on functions such as: Server Redundancy — an on-line synchronized backup provides high availability to your process. On-process Migration — migrate the Server software from a current release to the next available release without taking the Experion PKS System off line. All the functionality described in this document, including the options, are core functionality.
That is, it is developed as a system and licensed as options to allow users to simply purchase what is necessary. Options are not unwieldy add-ons that only manage to complicate the system. Options can be purchased at any time and added to your system with a simple license key. Most options do not even require an additional software installation. The following information is stored in the Real Time Database: Acquired Data — data read from or related to controllers?
Process History — historical store of acquired data? User Defined Data — structures to store application specific information To maintain data integrity, memory resident portions of the Real Time Database are periodically written to the hard disk in a process known as checkpointing. User Interface Subsystem For server-connected Stations, this subsystem manages two tasks: Writing data to the Station and reading data entered at the Station Acquisition and Control Subsystem For Control Execution Environment CEE devices, such as the C controller and ACE Application Control Environment node, this subsystem manages a dynamic cache of data for display on graphics, for history, and for use by external applications.

This cache grows and contracts dynamically depending on the needs of its users — Station displays, applications, etc. This is an extremely powerful mechanism as it means that not all data is polled from honeydell C controller and other CEE devices.
Rather, data is only subscribed and updated by exception based on a need from a user. And, if e;ks than one user or application requires the same set of data, the cache provides this data without making duplicate requests to the controller.
When users stop requesting data, the cache no longer asks for the data. When points are downloaded to the server using Quick Builder see page 12scan epkd are built that define how data will be acquired. Depending on the interface, report by exception and other scanning mechanisms are supported. Executive Subsystem Time keeping and scheduling is the major function of the Executive subsystem. In essence, this subsystem manages all scheduled tasks throughout the server.

Standard History ‘ 1 minute snapshot ‘ 6 minute average ‘ 1 hour average ‘ 8 hour average ‘ 24 hour average? Fast History ‘ User selected — 1, 2, 3, 4, 5 default10, 15, or 30 second snapshot? Extended History ‘ 1 hour snapshot ‘ 8 hour snapshot ‘ epls hour snapshot Historical data can be archived.
The archiving capabilities include the ability to retain archives epms the server hard drive, move the archive to another drive after a defined period of time, or to delete the archive after a defined period of time.
Archiving will not occur if the hard drive falls below a configurable amount of free space.
Once collected, historical data is available for use by rend displays? ODBC compliant database The archiving capabilities provide effectively unlimited honeyeell of historical storage. If additional history features are necessary,?
All alarms are recorded as events. Additionally, login actions, operator actions, and configuration changes are logged in the event journal. Report Subsystem The report subsystem is designed to create reports from a list of standard and optional reports. This subsystem maintains the report configuration for scheduled or ondemand execution. Redundancy Subsystem The redundancy subsystem is designed to fail over to a backup server in the event of a single failure of the primary or controlling server.
Please see the section titled Server Redundancy on page 13 for more details on this optional function. Configuration Subsystem The real time database manages the configuration information downloaded by Control Builder and Quick Builder.
Point Structures For Process points those points resident in CEE devices such as the C controllera standard database point structure is built in the Real Time Database upon download to the device. This point structure includes a minimum of necessary parameters. Additional parameters are dynamically added to the point database as needed when requested for display, history collection, etc. This supports the dynamic cache see the Acquisition and Control Subsystem section of this document by providing an explicit link to the data.
In this way, the cache does not have to learn where to get the data each time it is subsequently requested. Alarm and Event Subsystem Alarming for points from CEE devices, known as Process points, are alarmed and time stamped at the controller.
SCADA point alarms are initiated, time stamped, and acknowledged by the server. Each of the configured alarms can be assigned a priority ranging from Journal, Low, High to Urgent. OPC Advanced Points For further detail on the parameters associated with Analog, Status, and Accumulator point structures, please see page 27 in the Specifications and Sizing section of this document.

A container point combines a group of logically associated points into a single point structure. The container point parameters are flexible. For example, a container point could be built for a tank that includes the: Agitator status User-defined Parameters With each of the above point types, it is possible to add user-defined parameters to the existing pre-built parameters.
This enables tags to be extended to contain free format values, constant values, or values used by applications and scripts to store calculated or derived plant information. User defined honeywel, can be assigned to history collection.
These scripts can be enabled: The powerful scripting environment also enables Library scripts to be created, enabling repetitive logic to be simply applied on many points. For further details, please refer to the section titled Server Scripting on page User-defined Structure In order to support other types of data such as user entered or calculated data from application programs, the server provides a user-definable database area that is fully integrated into the system.
Data contained in this database is accessible by: Server based Application Programs? Network based Applications Programs? Composite points User-defined Data Formats Data formats convert field values into values that are more useful for operators and other applications.
When a SCADA point is configured to use an unscaled user-defined data format, the value is formatted, but not scaled, prior to loading it into the parameter. Therefore, the scaling for each parameter that uses the Algorithms In addition to standard point processing functions and VB scripting, the system allows additional processing through the use of standard algorithms honeywelk may be attached to an analog, status honyewell accumulator point.
Scaled userdefined data formats will format and scale a field value before loading it into the parameter. Refer to page 13 for more information about FTE. Ethernet Experion PKS Servers also support a network infrastructure of single or redundant Ethernet to communicate to nodes throughout the system. Server Scripting Server Scripting encompasses two features.
The first provides scripting support to allow the behavior of the Server-resident subsystems and its run time objects to be extended. Examples of server objects are: Points and Parameters described in the section titled Point Scripting? Tasks Application Programs The user configures these scripts to be hoenywell by the server either periodically or when a specified event occurs.
Honehwell addition, standard displays are supplied to allow the user to monitor the status of running scripts. Example scenarios of when to use server scripts include: These two features together form the Server Scripting support. The honeywwell employed by Server Scripting gives it great flexibility and functionality. There are some Figure 3. Consult Table 1 to help classify tasks into those that are well suited to Server scripting and those that are better addressed by a custom application.
Some tasks qualify for EP Version 1. Where possible, existing server functionality should be used in preference to writing Server scripts. Standard server functionality optimizes the task implementation. Code is compiled and optimized at build time.
