Abstract

A supervisory process control and manufacturing information system application is disclosed. The components of the application are distributable to a plurality of networked computer devices in a multi-layered hierarchical manner wherein lower layers host higher installed layers of application components. Application objects reside at a relatively high level of the distributed application architecture and model entities within a process control system. Engine objects host execution of the application objects in a run-time environment. Thus, application objects are not deployed until a host engine object with which they are associated have been deployed. Engine objects are hosted by platform objects. The platform objects correspond to a physical computer system component for executing the engine objects and associated application objects. A configuration facility presents a variety of views including deployment and model views of the application. The views incorporate the relationships of the objects that make up the distributed application.
