This part of IEC 60770 specifies the following methods.<\/p>\n
Methods for<\/p>\n<\/li>\n
assessment of the functionality of intelligent transmitters;<\/p>\n<\/li>\n
testing the operational behaviour, as well as the static and dynamic performance of an intelligent transmitter.<\/p>\n<\/li>\n
Methodologies for<\/p>\n<\/li>\n
determining the reliability and diagnostic features used to detect malfunctions;<\/p>\n<\/li>\n
determining the communication capabilities of the intelligent transmitters in a communication network.<\/p>\n<\/li>\n<\/ul>\n
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 (as specified in the IEC 61158 series or others) or into analogue electrical signals (as specified in the IEC 60381 series).<\/p>\n
The methods and methodologies listed in this part of IEC 60770 are intended for use by:<\/p>\n
manufacturers to determine the performance of their products, and<\/p>\n<\/li>\n
users or independent testing laboratories to verify equipment performance specifications.<\/p>\n<\/li>\n<\/ul>\n
Manufacturers of intelligent transmitters are urged to apply this part of IEC 60770 at an early stage of development.<\/p>\n
This standard is intended to provide guidance for designing evaluations of intelligent transmitters by providing:<\/p>\n
a checklist for reviewing the hardware and software design in a structured way;<\/p>\n<\/li>\n
test methods for measuring and qualifying the performance, dependability and operability under various environmental and operational conditions;<\/p>\n<\/li>\n
methods for reporting the data obtained.<\/p>\n<\/li>\n<\/ul>\n
