This part of IEC 60870, which is a technical specification, describes the transport profiles for the IEC 60870-6 series over WAN with reference to international standardized profiles (ISPs) used by distributed SCADA/EMS applications in control centres, power plants and substations. The transport profiles use virtually any standard or de facto standard (including TCP/IP) connection-mode and connectionless-mode network services over any type of transmission media.
These profiles are part of the telecontrol communication architecture (TCA).
