BS EN 60870-6-502:1996

What is BS EN 60870-6-502 - Telecontrol Application Service Element no. 1 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 60870-6-502 specifies the protocol for the services provided by an application-service-element – the Telecontrol Application Service Element no. 1 (TASE.1) – to support the exchange of process data between telecontrol systems. The main goals for the design of these services are:

• Simplicity
• Adaptability
• Independence of lower layer architecture
• Extensibility
• Efficiency
• Performance
• Maintainability

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

Note 1: BS EN 60870-6-502 is limited to the interconnection of systems.

Note 2:BS EN 60870-6-502 does not specify or restrict the possible implementation of interfaces within a telecontrol system.

Who is BS EN 60870-6-502 - Telecontrol Application Service Element no. 1 for?

BS EN 60870-6-502 on Telecontrol Application Service Element no. 1 is useful for:

• Telecommunication component manufacturers
• Telecommunication equipment manufacturers
• Design engineers
• Quality control personnel

Why should you use BS EN 60870-6-502 - Telecontrol Application Service Element no. 1?

Telecontrol equipment and systems function best when used from a short distance. BS EN 60870-6-502 specifies the protocol (abstract syntax) and the procedures for the Telecontrol Application Service Element. The Telecontrol Application Service Element no. 1 services are provided in conjunction with the Remote Operations Service Element (ROSE) services (ISO/IEC 9072-1) and the ROSE protocol (ISO/IEC 9072-2), and the Association Control Element (ACSE) services (ISO 8649) and the ACSE protocol (ISO 8650). The TASE.1 procedures are defined in terms of the interactions between peer Telecontrol Application Service Element no. 1 protocol machines through the use of Remote Operations Service Element services and the interactions between the Telecontrol Application Service Element no. 1 protocol machine and its service-user.

BS EN 60870-6-502 define a Telecontrol Application Service Element No. 1 Protocol Machine (TPM) using a state table descriptive mechanism. All tables are shown from the viewpoint of the Telecontrol Application Service Element no. 1 service provider. The state tables do not constitute a formal definition of the TPM. They are included to provide a more precise specification of the elements of procedure for the Telecontrol Application Service Element no. 1 services defined in the Telecontrol Application Service Element No. 1 Service Definition. The notation used in the state tables is the same as used in ROSE Protocol Specification, annexe A, and thus follows the same conventions. Using BS EN 60870-6-502 you can specify the protocol for the services provided by an application-service-element – the Telecontrol Application Service Element no. 1– to support the exchange of process data between telecontrol systems.
