ABB PM866 central processing unit
Composer is the comprehensive set of engineering and maintenance tools for
Harmony systems. It provides configuration support for all controller and INFI-NET
(Cnet) communication options. The working environment provided by Composer
simplifies the configuration and maintenance of Harmony systems. The base product
contains all the functionality necessary to create and maintain control system
configurations. In addition, it includes applications that support graphic configuration
and database management of all current operator console offerings.
Composer's multiuser client / server architecture allows configuration information to be
accessed, created, and modified simultaneously by different users. Composer's project
explorer provides the user with the ability to organize, navigate, and manage Harmony
system configuration documents. Once documents are located, Composer's explorer
can be used to launch the editors which are used to develop Harmony configurations.
Composer tools include:
View and Monitor: Provides the ability to view control configurations with live data
from any Windows based web browser application on the network (Figure 5)
Online Maintenance Tools: Provides users with the ability to trouble shoot,perform
diagnostics, and maintain the operating Harmony system
Standalone Configuration Viewer: Offers users an option to view CFG files or view
and tune configurations in a controller without requiring Composer software orprojects
Power Tools: Suite of add-on applications that extends the capabilities of Composer
and reduces the amount of time required to engineer and configure a Harmony
system. Applications include Control Logic Editor, Revision Manager,Automatic
Drawing Generator, and Advanced Trend (runtime monitoring and tuning)
Batch Data Manager (BDM): A family of engineering tools used for creating, editing,
managing, downloading, and debugging batch, sequential, and user defined
function code configurations.BDM is discussed further in the section "System 800xA
Production Management for Harmony”

The enabling technology for this data access, storage, and management is ABB's
patented Aspect Object ""framework. Aspect Objects relate all plant data; the aspects,
to specific plant assets; the objects. For example, aspects are informational items
associated with objects, such as I/O definitions, engineering drawings, process
graphics, reports, trends, etc., that are assigned to each object in the system. Aspect
Object navigation presents the entire production facility in a consistent, easy-to-view
fashion. This allows a single window environment to include smart field devices, asset
optimization functions, information management, batch management, safety systems,
and manufacturing execution system(MES) applications.
System 800xA Process Portal features include:
Personalized Workplaces for Focused Information Access: Workplace layouts
are adjusted and optimized to user preferences and needs with individualized
menus, toolbar contents, and display locations. Operator, maintenance, engineering,
and management personnel are at ease and perform their responsibilities efficiently
using Windows management functions, such as safe areas and pinning and stacking
priorities, thus minimizing operation errors.
Intuitive and Flexible Navigation for Fast Information Access: Familiar web
browser tools provide quick access to displays and information.Favorites, history
lists, shortcuts, and hot buttons provide navigation through a process production
facility quickly and accurately. Use of the right mouse button provides access to
additional details (Figure 8).
Integrated Data for Informed Decision-Making: ABB extends the automation
reach by integrating information from a wide range of ABB applications, other
automation systems, and business systems into System 800xA on common displays.
This single window provides users a much broader viewof the facility from which to
make more informed decisions(Figure 9).
Comprehensive Operator Functionality for Reliable Control: System 800xA
Process Portal provides a complete set of operator functions that includes realistic
process graphics with standard faceplates, superior trending capabilities, intelligent
alarm and event handling, production reporting, and remote messaging (Figure 10).
