measuring instruments — interface system ( byte serial, bit parallel ) — Part 2 : Codes, formats,
‘\;
protocolsand common commands’ issued by the International Electrotechnical Commission ( IEC )
was adopted by the Bureau of Indian Standards on the recommendation of Electronic Measuring
Instruments, Systems and Accessories Sectional Committee and approval of the Electronics and
Telecommunication Division Council.
Thisstandard(Part2)specifiesasetofcodes,formatsandcommunicationprotocolsforprogrammable
measuring instruments.
This standard was first published in 1983 and was identical to IEC 60625-2 ( 1980 ) ‘An interface
system for programmable measuring instruments ( byte serial, bit parallel ) — Part 2: Code and
formatconventions’. IEC60625-2 ( 1980) hassincebeen revisedin1993. Inviewofthetechnological
advances atthe internationallevel,thisstandardisbeingrevisedtoalignitwiththe latest internatior@
practices.
*
The textofthe IEC hasbeen.approvedassuitableforpublicationasIndianStandardwithoutdeviations.
Certainconventionsare, however,notidenticaltothoseusedinIndianStSndards.Attentionisparticularly
drawn to the following:
a) Wherever the words ‘InternationalStandard’ appear referringtothisstandard, they shouldbe
read as ‘Indian Standard’.
.—
b) Comma (,) has been usedas adecimal markerwhile inIndianStandards, the current practice
1 is to use a point (.) as the decimal marker.
