PD IEC TS 62098 aims at providing background information for developing evaluation methods for microprocessor-based instruments.
By using the checklists given in 4.2 and 4.3, the functions and properties that may be embedded in the function blocks of the instrument to be evaluated can be identified. Subclause 4.4 gives a checklist for the identification of the relevant influencing conditions for the instrument to be evaluated.
Depending on the application of an instrument, the user of this technical specification may have to define further functions and properties or influence conditions.
PD IEC TS 62098 on microprocessor-based instruments is useful for:
Microprocessor-based instruments are sampled-data systems. That means that the outputs and other relevant data are refreshed or updated with new data at certain time intervals or cycle times.
PD IEC TS 62098 specifies the definition and design of methods and means for measuring the functions and properties, methods and means to apply, measure, and control the test conditions to be imposed on the instrument, and consideration of results to be expected while evaluating for microprocessor-based instruments.
Overall, PD IEC TS 62098 assists you with the analysis of the instrument in terms of the external and internal information flows from and to the process, the human operator, and external systems. This will help you to identify the main function blocks in the instrument.
