14、essed in annex C of the technical report IEC 870-6-1 1*. This strategy defines the requirement to standardize only ISO/OSI compliant protocols, and to base the work on proven technology. The TASE.1 is aimed for use where utilities have a need for exchange of process data, e.g. real-time measurements
15、, breaker status, or energy counter values. The exchange can be on any level within the utility or between utilities using a data network. The network can be local or wide, public or private, but must be able to support standard ISO protocols. The TASE.1 is an application layer protocol and the corr
16、esponding service specifications are based on the ELCOM 90 de facto standard protocol. The services of the proved ELCOM 90 protocol have been moved into a full ISO stack of protocols where standard ISO protocols are used on all levels including layer 7. Some of the services of ELCOM 90 have been map
17、ped directly on the services of the ISO standards ACSE and ROSE while the remaining are included in the TASE.1 services. This solution will ensure a high degree of common software between different communication functions within a system and keep the cost of implementation at a minimum. Please refer
18、 to annex C of the technical report IEC 870-6-1 1* , for a description of how this TASE.1 fits into the overall architecture. The TASE.1 protocol will make it possible to exchange data values of different type between telecontrol systems at different levels, for example: real-time data values; histo
19、rical data set values; supervisory control data values; short text messages. Data transfer can be initiated and controlled in various ways, for example: periodic transfer; unsolicited transfer, event driven; requested transfer. The data transmission can be done on an individual data item value basis
20、, or data values can be grouped together for more efficient transmission. The protocol definition is prepared for introduction of new data types. If additional data types are required, these may be defined in an amendment by extension of the ASN.1 syntax of the protocol.The TASE.1 is designed to ope
21、rate together with other standard protocols and does therefore not provide functionality already available in other standards in use, for example FTAM for file transfer and X.400 for message transfer. _* Numbers in brackets refer to annex B, Bibliography.

22、AND SYSTEMS Part 6: Telecontrol protocols compatible with ISO standards and ITU-T recommendations Section 501: TASE.1 Service definitions 1 Scope and object This section of IEC 870-6 defines the services provided by a telecontrol specific application-service-element the Telecontrol Application Servi
23、ce Element No. 1 (TASE.1) for the exchange of process data in 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 fo
24、r defining, changing, deleting and inspecting information groups; services for managing the transfer of information groups and blocks of information from different groups; services for supervisory control. The TASE.1 services are provided by the use of the TASE.1 protocol (IEC 870-6-502) in conjunct
25、ion with the Remote Operations Service Element (ROSE) services (ISO/IEC 9072-1), the ROSE protocol (ISO/IEC 9072-2), and the Association Control Service Element (ACSE) services (ISO 8649) and the ACSE protocol (ISO 8650). The services defined in this standard allow communication between telecontrol
26、end systems. The primitives comprise a minimum set able to fulfil the following requirements: allowing the inclusion of OSI standard protocols for all layers; allowing extensions of the services to cope with future OSI requirements. The services can be applied for the exchange of realtime data, as w
27、ell as historical and planning data.EN 60870-6-501:1996 6 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this section of IEC 870-6.
