Patent ID: 8055743

Claim:
A computerized method of configuring a distributed network after replacing a node comprising: storing a plurality of network variables for a first device associated with a first node, wherein each of the network variables defines a respective input or output of the first device and a type of data passed via the corresponding input or output, each type of data being representative of an operating parameter of a building control system, wherein the step of storing further comprises storing a configuration table associated with the first node, an address table associated with the first node and a domain table associated with the first node; obtaining a plurality of network variables for a second device for the first node, each of the network variables for the second device defining a respective input or output of the second device and a type of data passed via the corresponding input or output; comparing the stored plurality of network variables to the obtained plurality of network variables; identifying a network variable from the stored plurality of network variables that is not defined in the obtained plurality of network variables; identifying an entry in a configuration table of a second node that corresponds to the identified network variable, the configuration table listing network variables passed to or from the second node; deleting the entry in the configuration table of the second node for the identified network variable; modifying the stored configuration table of the first node by deleting an entry in the stored configuration table for the identified network variable; modifying the stored address table of the first node by deleting an entry in the stored address table associated with the identified network variable; and writing the modified configuration table, the modified address table and the stored domain table to a replacement device.
