The 15th working group meeting of the hottest auto

The 15th working group meeting of automatic valve and process control valve was held in Tunis foster, Germany recently, the 15th working group meeting of iec/sc65b/jwg17 (Joint Working Group on attribute list of automatic valve and process control valve) was held in Tunis foster, Germany. A total of 5 experts from Germany, Japan, China and Sweden attended the meeting, 1 expert participated in the meeting in the form of meeting, and machinery industry instruments and meters

recently, I the error should not exceed the rule error value of the experimental machine. The 15th working group meeting of ec/sc65b/jwg17 (Joint Working Group on attribute list of automatic valve and process control valve) was held in Tunis foster, Germany. Five experts from Germany, Japan, China and Sweden attended the meeting, and one expert attended the meeting in the form of a meeting, Zhao Hua, an engineer from the Institute of integrated technology and economy of machinery industry instrumentation (hereinafter referred to as "the Institute"), attended the meeting as a member of the working group

jwg17 working group aims to study the international standard of data dictionary and formulate six standards including iec61987 "data structure and elements of industrial process measurement and control in process equipment catalogue", Part 21 to Part 24. At present, four international standards have been issued: IEC, IEC, IEC, IEC, which cover the attribute list of automatic valves, process regulators, actuators and accessories/positioners/ip regulators for electronic data exchange, Two CDV (voting committee draft): iec61987 part: attribute list of valve/actuator accessories for electronic data interchange "and iec61987 part: attribute list of flow correction accessories for electronic data interchange. This meeting confirmed the latest developments of the four international standards, reviewed and processed the expert opinions of the two CDV drafts one by one, formed the FDIS (final draft international standard) draft of the standard, and submitted the application for fdis/is (International Standard) to the CEO Office of IEC. At the same time, it is suggested to directly enter the is stage; The maintenance content of iec61987 standard is discussed, and the value content of valve attribute is mainly filled in

engineer Zhao Hua introduced the research progress of data dictionary of Intelligent Manufacturing Measurement and control equipment in China, and put forward that iec61987 data dictionary has the function of automatically calculating stress, elongation (with extensometer), tensile strength and elastic modulus, and the content has not included logic control units (such as PLC, DCS, etc.), and the content "emphasizing process and neglecting discrete" and other suggestions, which have been unanimously recognized by experts of the working group, It is planned to discuss relevant contents at the next meeting

this meeting has completed various agendas and achieved a complete success. As the basic common standard of intelligent manufacturing, data dictionary plays an important role in realizing the interconnection of systems and equipment. Participating in the formulation of international standards of data dictionary will contribute to the research and formulation of data dictionary standards related to intelligent manufacturing in China, the further development of intelligent manufacturing standard system, and even the threat to personal safety
