Telecontrol equipment and systems - Part 6-702: Telecontrol protocols compatible with ISO standards and ITU-T recommendations - Functional profile for providing the TASE.2 application service in end systems
This part of IEC 60870 is a functional profile (FP) and defines the provision of the TASE.2 communications services between two control centre end systems. It is supported by the transport services implemented in accordance with transport-profiles defined for the type of network that interconnects the control centre end systems. This is demonstrated in figure 1.
This FP also defines the provision of the OSI connection-mode presentation and session services between the end systems.
ISO/ISP 14226 specifies the AMM11 profiles for MMS. The parts of ISO/ISP 14226 that cover the profile that are used as a basis for this FP are ISO/ISP 14226-1 and ISO/ISP 14226-2. This FP is in alignment with ISO/ISP 14226, as far as possible, and maintains this compatibility by reference. There are TASE.2 requirements in addition to ISO/ISP 14226. These requirements are specified in this FP.
