What is BS EN 60870-5-5 - Basic application functions about?
BS EN 60870 is a series on telecontrol equipment and systems. Telecontrol equipment and systems is an electronic device used to operate another device from a distance, usually wirelessly. BS EN 60870-5-5 applies to telecontrol equipment and systems with coded bit serial data transmission for monitoring and controlling geographically widespread processes. BS EN 60870-5-5 defines basic application functions that perform standard procedures for telecontrol systems. Basic application functions are application procedures that reside beyond layer 7 (application layer) of the ISO reference model for open communication systems. The defined application procedures utilize standard services of the application layer. BS EN 60870-5-5 serve as basic standards for different companion standards that will be elaborated in detail for specific telecontrol tasks. Each companion standard may use a specific selection of the defined functions. Basic application functions, which are not in
