ABSTRACT

This chapter explains that decentralizing the desired functionality onto multiple Neuron chip-based nodes is, besides using a more powerful platform, sometimes the only solution to achieve reasonable response times. The LonTalk® Communication Protocol defines rules for the communication in LonWorks networks. The Neuron chip task scheduler that controls the flow of the application program allows event-oriented programming in C. The main functions of the LonTalk protocol are processed by the transport layer and the session layer. Layer 4 can be split up into transaction control sublayer, authentication server, and transport layer. A CEA-709 node can send a unicast addressed message to exactly one node using either the physical Neuron ID, or the logical subnet/node (S/N) address, or a multicast addressed message to either a group of nodes or to all nodes in the subnet or all nodes in the entire domain.
