The work of preparing International Standards is normally carried

8、out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO

9、collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare Internationa

10、l Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the eleme

11、nts of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 20242-4 was prepared by Technical Committee ISO/TC 184, Automation systems and integration, Subcommittee SC 5, Interoperability, integration, and architectur

12、es for enterprise systems and automation applications. ISO 20242 consists of the following parts, under the general title Industrial automation systems and integration Service interface for testing applications: Part 1: Overview Part 2: Resource management service interface Part 3: Virtual device se

13、rvice interface Part 4: Device capability profile template The following parts are under preparation: Part 5: Application program service interface Part 6: Conformance test methods, criteria and reports ISO 20242-4:2011(E) ISO 2011 All rights reserved vIntroduction The motivation for ISO 20242 stems

14、 from the desire of international automotive industries and their suppliers to facilitate the integration of automation and measurement devices, and other peripheral components for this purpose, into computer-based applications. ISO 20242 defines rules for the construction of device drivers and thei

15、r behaviour in the context of an automation and/or measurement application. The main goal of ISO 20242 is to provide users with: independence from the computer operating system; independence from the device connection technology (device interface/network); independence from device suppliers; the abi

16、lity to ensure compatibility between device drivers and connected devices, and their behaviour in the context of a given computer platform; independence from the technological device development in the future. ISO 20242 does not necessitate the development of new device families or the use of specia

17、l interface technologies (networks). It encapsulates a device and its communication interface to make it compatible with other devices of that kind for a given application.

18、interface for testing applications Part 4: Device capability profile template 1 Scope This part of ISO 20242 defines the formatting, syntax and semantic rules for describing device and coordinator capabilities with XML schema, and the configuration of devices with XML. NOTE This part of ISO 20242 do

19、es not address the coordinator configuration, which will be addressed elsewhere in the ISO 20242 series. 2 Normative references The following referenced documents are indispensable for the application of this document.

29、e used. The generic DCPT shall use the generic information exchange profile template of ISO 15745-1 as a skeleton and shall be constructed in XML schema. The technology-specific DCPT describes technology- specific capabilities and shall extend the generic DCPT in XML schema. A DCD describes capabili

30、ties of virtual devices in a device driver and shall extend a technology-specific DCPT in XML schema. A CCD describes capabilities of a coordinator and shall extend a technology-specific DCPT in XML schema. A CCD imports DCDs for device drivers and describes capabilities of a system. A parameterizat

31、ion instance description (PID) describes configurations of a coordinator and device drivers. A PID shall be constructed by instantiations of one CCD and one to many DCDs. The PID is a realization of the information exchange profile in ISO 15745-1 and can be used together with other profiles of ISO 1

33、he class diagram of CCD and DCD in the framework. The generic DCPT specifies the aggregate of the generic CCD and generic DCD. The generic CCD describes generic capabilities of a coordinator. The generic DCD describes generic capabilities of virtual devices. The technology-specific CCD in a technolo

36、bes coordinator-specific capabilities. The name of a coordinator-specific CCD can be described by the coordinator-specific name. The device-specific DCD shall inherit the technology-specific DCD and shows device-specific capabilities. The name of a device-specific DCD can be described by the device-

37、driver-specific name. Between the generic CCD and the generic DCD, there shall be an aggregation relation as shown in Figure 2. A generic CCD may contain one to many generic DCDs. Different generic CCDs may use the same generic DCD. Generic DCDs may exist without a generic CCD. The coordinator-speci

38、fic CCD and the device-specific DCD have the aggregation relation from inheritance. A CCD can import the DCDs of device drivers. The CCD instance in a PID shall be an XML instance of the coordinator-specific CCD XML schema. A DCD instance in a PID shall be an XML instance of a device-specific DCD XM

39、L schema. The XML tag name of a CCD instance shall be the name of the coordinator-specific CCD. The XML tag name of a DCD instance shall be the name of the device- specific DCD. 5.2 Creation procedure of DCD, CCD and PID 5.2.1 General Figure 3 shows the creation procedure of DCD and CCD. Clause 6 de

40、fines the generic DCPT in XML schema. The technology of each service interface defines technology-specific capabilities as a technology-specific DCPT. NOTE Technology-specific DCPTs for ASAM GDI, MICX and ORiN are described in Annexes A, B and C. The vendor of a device, equipment or software module

41、shall extend the technology-specific DCD of the technology-specific DCPT with the capabilities of the device or equipment. The resulting DCD XML schema shall be provided together with a device driver. The vendor of a coordinator shall extend the technology-specific CCD of the technology-specific DCP

42、T with the capabilities of the coordinator. The resulting CCD XML schema shall be provided with the coordinator. A configuration tool can import the CCD and the required DCDs to create the PID XML instance with the configuration data for the required application. The PID shall contain all required i

43、nstances with names and values. The coordinator can read the PID XML instance and perform a coordinator setup and the configuration of devices, equipment or software modules. The configuration shall be performed via the virtual device service interface (VDSI) of the device drivers as defined in ISO
