ABB 污水处理器以及发电厂分布式控制系统Symphony Plus

Composer applications 

The base Composer product contains all the functionality necessary to develop and maintain Symphony Plus control system configurations. There are two primary applications: explorer and automation architect.

Explorer 

The primary application of Composer is the explorer. Explorer presents the Symphony Plus, Symphony or INFI 90 OPEN system architecture and provides an intuitive means for organizing, navigating and locating system configuration information. Explorer presents a user with two main windows: system architecture and object exchange.

System windows 

The system architecture window functions similarly to Microsoft’s file explorer. The left pane of the window displays a hierarchical representation of the Symphony Plus system. When a system object is selected, the right pane displays a detailed view for the selected object.

The system window supports two views: the document view (figure 1) and the data browser view (figure 2). When the system window is in the document view, it will show the configuration documents that are associated with the system object that the user has selected. Configuration documents support long file names and can include control logic documents, human system interface displays, or documents created by other applications such as CAD packages or spreadsheets.

The ability to associate any documents with the system architecture is an important feature. This allows any information, such as piping and instrumentation diagrams (P&IDs), cabinet arrangement drawings or field wiring drawings, to be managed by the configuration server and accessed by Composer client applications. All that is required to edit any of these documents is to double-click the document. 

Composer’s explorer will automatically launch the appropriate application for the document selected. When the system window is in the data browser view, the right pane of the system architecture window will display tag information associated with the system object the user has selected. All tag information presented is retrieved from the configuration server database that is managed by the Composer server. 

When working in the data browser view, users can view, define and modify tag data for the whole system. 

This central repository of data is managed by Composer’s configuration server for all tag data in the entire system. The data for each tag is added to the configuration server database as each tag is defined. This eliminates the need for users to enter the same information more than once. Some notable features of the data browser view are the ability to: − Edit tag objects in a datasheet or property page view − Filter the database: filtering makes configuration easier and faster by eliminating unnecessary information from view 

− Import and export tag data 

− Navigate directly from a tag to its related configuration document 

− Perform automatic search and replace operations based on complex queries

Composer supports INFI 90 OPEN, Symphony and Symphony Plus systems of all sizes. For small systems, as shown in figure 14 and 15, Composer’s configuration server, communications server and client applications are all loaded onto a single engineering workstation PC. The software components communicate with each other using inter-process communications within the engineering workstation PC.

For larger systems, Composer’s software supports client/ server architecture over an Ethernet TCP/IP network. Figure 15 and 17 shows how the Composer software components may be distributed over a client/server network to provide a multiuser engineering environment. The configuration server (project database) can be loaded on any file server within the Ethernet network that client workstations can access
