Telecontrol equipment and systems - Part 5: Transmission protocols; section 5: Basic application functions (IEC 60870-5-5:1995); German version EN 60870-5-5:1995
The document applies to telecontrol equipment and systems with coded bit serial data transmission for monitoring and controlling geographically widespread processes. It defines basic application functions that perform standard procedures for telecontrol systems, i.e. application procedures that reside beyond layer 7 (application layer) of the OSI basic reference model for open communication systems. The specification of this document serves as basic standards for different companion standards that will be elaborated in detail for specific telecontrol tasks.#,,#
