Abstract :
An electric utility communication concept for providing services at the application layer is described. Specific protocols were developed for the application and presentation layer. Standardized ISO protocols for both connection-oriented and connectionless communication were used on lower layers. A possible migration to full ISO compatibility is described. The first version of the concept was specified in 1983 (ELCOM-83). The first implementation was installed in 1985 for communication between a background computer and a SCADA system. Additional facilities (supervisory control, text messages, transport service, etc.) were added in the next version (ELCOM-90). The implementation of ELCOM in a SCADA environment is discussed
