A control system methodology that uses object-oriented software to integrate multiple control systems into a common object model. Object-oriented techniques are used to construct distributed applications in a multi-vendor open system environment for use in controlling and monitoring systems of varying size and configuration. Information is brought into a common object model and made available throughout the system. A custom programming language is included for object creation. Access to objects is controlled through a multi-level security protocol. Data flow is governed by a real-time information synchronization manager. Classes are used to implement the system in a platform independent way according to a 'core class hierarchy' in which objects are organized to inherit behavior and perform predictably. A control engine allows the user to control the order of execution of objects. A script is provided for generating custom objects.

A network management system includes an embedded node, having network database and communications elements, which is coupled locally on an ECHELON network. This local coupling provides a relatively high bandwidth connection to accommodate relatively high traffic volume between the network database and nodes for improved system performance relative to prior art configurations. Locally coupling the network database to the network eliminates the need to tunnel various messages needed to effect a network service when using a tiered architecture common in the HVAC industry. The communications elements include com ports adapted to couple the embedded node to a workstation via a conventional network, and to an ECHELON network.
