Scope and object
This section of IEC 870-6 specifies the protocol for the
services provided by an application-service-element - the
Telecontrol Application Service Element no. 1 (TASE.l) - to support
the exchange of process data between telecontrol systems.
The main goals for the design of these services are:
- independence of lower layer architecture;
The services of TASE.1 are:
- services for defining, changing, deleting and inspecting
groups of information;
- services for managing the transfer of information groups
and blocks of information from different groups;
- services for supervisory control.
This section of IEC 870-6 specifies the protocol (abstract
syntax) and the procedures for the Telecontrol Application Service
Element (TASE). The TASE.1 services are provided in conjunction
with the Remote Operations Service Element (ROSE) services (ISOAEC
9072-1) and the ROSE protocol (ISO/iEC 9072-2), and the Association
Control Element (ACSE) services (IS0 8649) and the ACSE protocol
The TASE.1 procedures are defined in terms of:
b) the interactions between peer TASE.1 protocol machines
through the use of ROSE the interactions between the TASE.1
protocol machine and its service-user.
The scope of the protocol is limited to the interconnection of
systems. It does not specify or restrict the possible
implementation of interfaces within a telecontrol system.
