IEC 104 Overview

IEC 104 is a client/server communications protocol originally developed for use in the electric
utility sector for power transmission and distribution systems. It has migrated to other vertical
markets, and is now a general market protocol based on a 3-layer protocol scheme. IEC 104 is a
generational protocol coming from a foundation of the IEC 60870-5-101 protocol.
