What are Network Variables and SNVTs?

  • The LonTalk protocol provides a common applications framework that ensures interoperability using powerful concepts called network variables and SNVTs (Standard Network Variable Types).
  • Communication between nodes on a network takes place using the network variables that are defined in each node.
  • The use of Standard Network Variable Types (SNVTs, pronounced “snivets”) contributes to the interoperability of LonWorks products from different manufacturers.
  • Echelon maintains a growing list of over 100 SNVTs for nearly all physical measurement types including the type of variable such as integer or floating point.
