The iec/sc65e/wg2 data dictionary standard working group meeting was held in Germany

on December, 2017, the iec/sc65e/wg2 measuring equipment attribute list working group meeting for electronic data exchange was held at BASF headquarters in Ludwigshafen, Germany, with 10 experts from Germany, the United States, China, Japan and Switzerland participating. On December, 2017, the working group meeting of iec/sc65e/wg2 "attribute list of measuring equipment for electronic data exchange" was held at BASF headquarters in Ludwigshafen, Germany, with 10 experts from Germany, the United States, China, Japan and Switzerland participating

engineer Zhao Hua of the Institute of integrated technology and economy of instruments and meters in the machinery industry (hereinafter referred to as "the Institute") attended the meeting as a member of the working group. WG2 is the main working group of the International Electrotechnical Commission to develop standards related to data dictionaries, which aims to study a standardized method of describing industrial process measurement and control equipment, and how to use these description information to realize data exchange between two computer systems, and formulate some standards of iec61987 "data structures and elements in the catalogue of industrial process measurement and control process equipment"

this meeting was presided over by Mr. Peter zgorzelski, the convener of the working group. First of all, the status of seven parts of iec61987 series standards in the charge of the working group was confirmed, including the release of five international standards, one final draft international standard (FDIS), and a new project proposal for the development of some corresponding product technologies in the Shanghai R & D center to shorten the cycle (NP). Then, the experts of the working group processed all the opinions put forward by the draft of IEC (data structures and elements in the catalogue of industrial process measurement and control process equipment - Part 92 additional aspects of the attribute list of measurement equipment for electronic data exchange), formed the final text of this part of the standard and submitted it to the CEO Office of IEC, and this part of the standard will enter the approval stage; The update and release of the above five published international standards in IEC CDD (public data dictionary) were discussed, and it is planned to be completed and browsed free of charge in February 2018. At the meeting, Zhao Hua, an engineer of the Institute of instrumentation and electronics, made a thematic report entitled "the latest research progress in CDD in China", shared the research status of domestic data dictionary, including the development of relevant standards, the application and implementation of CDD and the problems encountered, and put forward suggestions on developing case studies of data dictionary applications. The content of the report attracted the high attention and heated discussion of the participating experts, and it was suggested that the Chinese data dictionary standard should be transmitted to IEC CDD

with the in-depth development of industry 4.0 and intelligent manufacturing, data dictionary is considered to be the key and basic standard to realize the "interoperability" of infrastructure equipment in different systems, factories and enterprises around the world. It has been widely concerned in the International Electrotechnical Commission. Experts of WG2 working group have been invited to many IEC working groups related to intelligent manufacturing, For example, ahg1 (intelligent manufacturing information, which uses a series of reference voltages (like the code dispelling used when weighing the balance) and the input voltage to be converted (weighing object) information model), ahg3 (intelligent manufacturing framework and system architecture), wg16 (Digital Factory), etc., communicate and share the research progress of CDD. Our country sends experts to participate in the formulation of IEC data dictionary standard, which can not only keep up with the latest research progress of the international standard of data dictionary, but also transmit the latest achievements of our independent research to the world because of its multi-function and often called friction tester and wear tester, which is of great significance for the formulation of domestic and international data dictionary standards
