2008 International Conference on Functional Safety Standards

And so on. For Safestate,[link widoczny dla zalogowanych], the expression is the expression of the state is safe, so it should be expressed as Safestate. Professor Feng after careful consideration that the process industry as a solution, related to the large amount of manpower and resources and associated with the lives and property, to be precise with words, so as to ensure that ambiguity does not exist in practical applications, this working group decision is very meaningful, very much agree with this proposal. Functional safety protocol for EPASafty,[link widoczny dla zalogowanych], IECWG12 Working Group also proposed other amendments, which is behind the EPASafety functional safety follow-up to the direction of communication protocols. First, as the function of other companies have adopted security protocols TuV certification function to get the corresponding safety certificate, so IECWG12 head of the Working Group requested that in June 2009 before the product's features to get EPASafety safety certificate . Second, the functional safety protocol EPASafety Fail-safe in the revised safety, IEC617984-3 Fail-safe no longer appears in the word, all amendments to safety; third section elaborates 9_3 response time of security features in detail describes each of these definitions and the mathematical formula to be specific; Fourth, consider carefully EPASafety agreement document should, could, may, can and other usage, and strive to express accuracy. 3 other meetings in other working groups also described the progress of work. Meeting of technical experts of Siemens of Germany requested the assessment of a mechanical safety guide for a GS-ET 26 to IEC61784-3-0, as its Annex D. This is a very worthy of our attention to the proposal. First,[link widoczny dla zalogowanych], the function of security technology experts Siemens HansWolfgangStrip this proposal were introduced in detail. These proposals mainly include: Conference Report (1) different types of system residual error probability calculation method. Introduced the white channel communication model for different types of communication failure probability of the residual method. (2) verification of safety measures. Consists mainly of specific implementation, power release (De-ellergizetoTrip) principles, security status, transmission error, security response and response time, a combination of various security measures to check the safety measures and other aspects of the implementation. (3) Environmental testing and validation. Mainly include the following elements: the operating environment and test methods; test conditions, user manuals, EMC test levels, logo and nameplate, mechanical testing, electrical creepage distance and clearance and so on. This feature of our safety standards into the IEC international standard EPASafety is undoubtedly a very serious signal. Professor Fung realized that this was to add the hardware in the standard Siemens assessed a mandatory requirement. Siemens experts has finished, IECWG12 the head of the ValerieDemassieux President to seek the views of everyone, all the company's experts have different opinions. Professor Fung said, IEC61784-3 is a communication protocol safety standards, assessment should not be adding the contents of the hardware, so the proposal was still in discussion. This makes us realize the function of EPASafety pressure transmitter must pay close attention to the safety certification of completion. 4 Harvest and the results of the meeting of the main results is that by the meeting of the exchange and learning, we learn a number of other companies at home and abroad functional safety standard protocols, the real insight into the IEC standard committee experience and technical experts ,[link widoczny dla zalogowanych], which we work as a technician in the promotion of literacy and has further improved. Particularly important to improve our understanding of international standards, and accumulated some experience. Advice of experts in the IEC,[link widoczny dla zalogowanych], EPASafety function more perfect security protocols. In addition, the deeply studied the work of IEC experts dedicated spirit. This meeting, as large as a function of the concept of security, as small as a problem of whether to add a comma, IEC of experts will discuss the research intentions. IEC experts dedicated to the spirit that should learn. Zhejiang University, this meeting is to provide an excellent opportunities for international academic exchanges, scholars from various countries report excellent functional safety technology currently provides the most cutting-edge information that can enable us to understand the latest technologies and development of the subject methods. Not only enhance the success of the meeting held in the control of our school and the influence of international academic groups, but also for the future development of the school to establish a more extensive international contacts.
