18、ndardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, IEC publishes I
19、nternational Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may partici
20、pate in this preparatory work. International, governmental and non- governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement betw
21、een the two organizations. 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested IEC National Committees. 3) IEC Publicatio
22、ns have the form of recommendations for international use and are accepted by IEC National Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, IEC cannot be held responsible for the way in which they are used or for an
23、y misinterpretation by any end user. 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and the corresponding
24、 national or regional publication shall be clearly indicated in the latter. 5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any equipment declared to be in conformity with an IEC Publication. 6) All users should ensure that they have the latest ed
25、ition of this publication. 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members of its technical committees and IEC National Committees for any personal injury, property damage or other damage of any nature whatsoever, whether d
26、irect or indirect, or for costs (including legal fees) and expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications. 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is indispe
27、nsable for the correct application of this publication. 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. A PAS is a technical specification
28、not fulfilling the requirements for a standard but made available to the public. IEC-PAS 62453-4 has been processed by subcommittee 65C: Digital communications, of IEC technical committee 65: Industrial-process measurement and control. The text of this PAS is based on the following document: This PA
29、S was approved for publication by the P-members of the committee concerned as indicated in the following document Draft PAS Report on voting 65C/398A/NP 65C/411/RVN Following publication of this PAS, which is a pre-standard, the technical committee or subcommittee concerned will transform it into an

34、components for Function Control and Data Access within a Client Server architecture. The specification is a result of an analysis and design process to develop standard interfaces to facilitate the development of servers and clients by multiple vendors that shall inter-operate seamlessly. With the i
35、ntegration of fieldbusses into control systems, there are a few other tasks which must be performed. This applies to fieldbusses in general. Although there are fieldbus- and device-specific tools, there is no unified way to integrate those tools into higher level system- wide planning or engineering
36、 tools. In particular, for use in extensive and heterogeneous control systems, typically in the area of the process industry, the unambiguous definition of engineering interfaces that are easy to use for all those involved, is of great importance. A device-specific software component, called DTM (De
37、vice Type Manager), is supplied by the field device manufacturer with its device. The DTM is integrated into engineering tools via the FDT interfaces defined in this specification. The approach to integration is in general open for all kind of fieldbusses and thus meets the requirements for integrat
38、ing different kinds of devices into heterogeneous control systems.

This PAS neither contains the FDT specifica
40、tion nor modifies it. 2 Normative references The following referenced documents are indispensable for the application of this PAS. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies IEC 62453-

The refer
42、enced channel must include ranges and scaling. 3.2 SingleDataAccess interfaces At least all parameters of the Universal and Common Practice (as far as the device supports the function) commands must be exposed via the interfaces IDtmSingleDeviceDataAccess and IDtmSingleInstanceDataAccess. Furthermor
43、e the Response Byte 0 and the Response Byte 1 for each command must be exposed. 4 Protocol specific usage of XML attributes The following Table 1 shows how general attributes are used with HART devices. Table 1 Protocol specific usage of XML attributes Attribute Description for use in HART address T
44、he address attribute (defined in FDTDataTypesSchema.xml) is not mandatory for the exposed parameters in the DTMs. But if the address attribute is used the string must be constructed according to the rules of the semanticId. That means the attribute semanticId is always the same as the attribute addr
