Abstract
A distributed computer-implemented building automation system for supporting applications that interact with building automation devices. The building automation system has a first device and a second device interconnected across a network channel. A common object superclass stored in a computer readable memory defines a plurality of common objects through instantiation such that the common objects have attributes for storing data and have methods for processing stored data. A source object residing on the first device performs a first control method such that a first attribute of the source object is changed. A destination object residing on the second device performs a second control method using the first attribute of the source object. A surrogate object connected between the source object and the destination object has a value for the first attribute and represents the source object on the second device. The second object has access to the value of the first attribute for performing the second method.
