NETWORKED VARIABLES

摘要

An improved apparatus and method for communicating information in a networked system wherein variables are employed to accomplish such communication. Network variables allow for standarized communication of data between nodes (301-305) in a network. A first node (301) may be programmed, for example, to sense certain information and to report the information as a network variable X. A second node (302) may be programmed to receive the variable X and to control devices based on the current value of the variable. The present invention provides for defining connections (201) between the first and second node to facilitate such communication and for determining addressing information to allow for addressing of messages, including updates to the value of the variable X, between the nodes.
