26、or testing the immunity to degradation in time39 EN 60770-3:2006 5 INTRODUCTION New transmitters for use in industrial process control systems are now equipped with micro-processors which utilise digital data processing and communication methods, auxiliary sensors and artificial intelligence. This m
27、akes them more complex than conventional analogue transmitters and gives them considerable added value. An intelligent transmitter is an instrument that uses digital data processing and communication methods for performing its functions and for safeguarding and communicating data and information on
28、its operation. It may be equipped with additional sensors and functionality which support the main function of the intelligent transmitter. The variety of added functionality can for instance enhance accuracy and rangeability, self-test capabilities, and alarm and condition monitoring. Therefore acc
29、uracy-related performance testing, although still a major tool for evaluation, is no longer sufficient to show the flexibility, capability and other features with respect to engineering, installation, maintainability, reliability and operability. Because of the complexity of intelligent transmitters
30、, a close collaboration should be maintained between the evaluating body and the manufacturer during the evaluation. Note should be taken of the manufacturers specifications for the instrument, when the test programme is being decided, and the manufacturer should be invited to comment on both the te
31、st programme and the results. His comments on the results should be included in any report produced by the testing organisation. This part of IEC 60770 addresses, in its main body, structured and mandatory methods for a design review and performance testing of intelligent transmitters. Intelligent t
32、ransmitters will, in many cases, also have the capacity to be integrated into digital communication (bus) systems, where they have to co-operate with a variety of devices. In this case, dependability, (inter)operability and real-time behaviour are important issues. The testing of these aspects depen
33、ds largely on the internal structure and organisation of the intelligent transmitter and the architecture and size of the bus system. The Annexes A, B and C give a non-mandatory methodology and framework for designing specific evaluation procedures for dependability and throughput testing and functi
34、on block testing in a specific case. When a full evaluation, in accordance with this part of IEC 60770, is not required or possible, those tests which are required, should be performed and the results reported in accordance with the relevant parts of this standard. In such cases, the test report sho
35、uld state that it does not cover the full number of tests specified herein. Furthermore, the items omitted should be mentioned, in order to give the reader of the report a clear overview. The structure of this part of IEC 60770 largely follows the framework of IEC 62098. For performance testing, the
36、 IEC 61298 series should also be consulted. A number of tests described there are still valid for intelligent transmitters. Further reading of the IEC 61069 series is recommended, as some notions in this part of IEC 60770 are based on concepts brought forward therein. EN 60770-3:2006 6 TRANSMITTERS
37、FOR USE IN INDUSTRIAL-PROCESS CONTROL SYSTEMS Part 3: Methods for performance evaluation of intelligent transmitters 1 Scope and object This part of IEC 60770 specifies the following methods. Methods for reviewing the functionality and the degree of intelligence in intelligent transmitters; testing
38、the operational behaviour, as well as the static and dynamic performance of an intelligent transmitter. Methodologies for determining the reliability and diagnostic features used to detect malfunctions; determining the communication capabilities of the intelligent transmitters in a communication net
39、work. The methods and methodologies are applicable to intelligent transmitters, which convert one or more physical, chemical or electrical quantities into digital signals for use in a communication network or into analogue electrical signals (as specified in the IEC 60381 series). The methods and me
40、thodologies listed in this part of IEC 60770 are intended for use by: manufacturers to determine the performance of their products and users or independent testing laboratories to verify equipment performance specifications. Manufacturers of intelligent transmitters are urged to apply this part of I
41、EC 60770 at an early stage of development. This standard is intended to provide guidance for designing evaluations of intelligent transmitters by providing: a checklist for reviewing the hardware and software design in a structured way; test methods for measuring and qualifying the performance, depe
42、ndability and operability under various environmental and operational conditions; methods for reporting the data obtained. 2 Normative references The following referenced documents are indispensable for the application of this document.
