The present invention includes a system (FIG.) for servicing messages between device controller nodes and control applications via a Lon Network, wherein the device controller nodes includes a plurality of network variables for defining parameters of the Lon Network. The system includes a server for servicing the messages from at least one control application, a proprietary communication value for indicating a network variable value from the control applications, and a Lon value for indicating a network variable value exposed on the Lon Network. There is also a method that includes the steps of reading a message from the control application, verifying whether the message is valid, determining the requested function for a specified network variable from the message when the message is valid, executing the requested function for the specified network variable, and sending subscribed reports in response to a change of value of the network variables independently of the foregoing steps ().
