800XA 系统概述（培训）

1 2Distributed Control Systems have been deployed extensively around the world in process and manufacturing industries to achieve productivity improvements by reducing process variability,increasing production availability,and automating tasks.These improvements were gained by focusing primarily on process control.In the 1990s ABB led the evolution of control system technology by introducing Open Control Systems.OCSs aimed to“open up”the control system environment,making information from the plant floor available to other applications,and allowing OCS systems to interface with other applications principally related to keeping the process running smoothly.It also marked the first major incorporations of“off-the-shelf”technology to replace proprietary versions of Operator Stations,Engineering Stations,and the like.However,the focus was still primarily on the controlling the process.Today,to deliver additional productivity gains it is necessary to extend the reach of the automation system beyond the world of process control.As mentioned above the traditional DCS/OCS functionality has been the Operations,Engineering,and logic to achieve consistent and predictable Process Control.The Operations functions were focused on the needs of the production operator.Interfaces to applications and devices external to the control system with their own data storage typically were collected and duplicated in the control system database to provide accessibility for reporting and operations needs.This approach was found to be difficult to engineer and maintain.The practice of having information stored in multiple locations brought uncertainty of data integrity as the individual software applications were advanced at asynchronous paces and the customized interfaces between them required frequent maintenance.The increasing deployment of peripheral applications related to productivity improvement such as quality systems,advanced control,production management,information management,and maintenance management resulted in different user interfaces for different types of information sources.More recently the availability of“smart field devices has vastly increased the amount of data available to improve productivity in a plant,utility,or mill.However,each device has its own data collection and communication environment,adding to the complexity of the integration task.With the introduction of System 800 xA,ABB,redefines the standard for control system functionality by extending the reach of the automation system.From an information access and integration perspective the IndustrialIT system incorporates functionality far beyond process control.Specifically,the system incorporates Process Control,Production Management,Safety,Discrete Logic and Sequence Control,Advanced Control,Information Management,Smart Instrumentation,Smart Drives and MCCs,Asset Management,and Document Management capabilities in a singular virtual database environment.The Aspect Object technology inherent to IndustrialIT provides the unifying platform base allowing each application to maintain data in its source application,while providing association to a production asset.This allows access to the data directly from it source in the context of the production asset without the need to know where the data is coming from,and without concern about data integrity and concordance.The ability to extend control engineering standards to incorporate and maintain connections to the wealth of IndustrialIT applications we have discussed,and to deploy these standards efficiently across all like instances is one of the unique characteristics of ABBs solution.This elegant solution addresses the engineering and maintenance issues of past solutions.This new IndustrialIT Extended Automation System 800 xA provides for a single operations,engineering,and information management environment for the complete scope depicted in this diagram.Meet the Aspect Integrator Platform,a revolutionary open architecture for managing,optimizing every link in the enterprise value chain.This powerful Microsoft Window-based architecture sets the standard for every IIT product from ABB and its partners.The Aspect Integrator Platform is a software package that integrates all Industrial IT enabled products via their Aspect Objects,irrespective of where they may reside.In the grand scheme of IndustrialIT,the information required to support each plant component and each business process is defined as an Aspect Object.An Aspect Object contains all the characteristics or Aspects of the item in question.For an electric motor,this could include design drawings,control diagrams,maintenance information,location,quality information and performance trends,even a live video of it in action.But an Aspect Object can also be finished products,raw materials,sales and orders.The key to Aspect Object technology is,however,that it is much more than real-time information.It also defines a set of software functionsb so that every
