This standard applies to nuclear instrumentation but may be utiiized also for other applications. Further IEC standards may indicate such extensions of this scope. For reactor instrumentation and control systems, other packaging of electronic nuclear instruments may also be used.
2.1 This standard applies to systems consisting of modul?r electronic instrument units that require input/output transfers for the purpose of digital data processing, normally in association with a form of common controller, computer or other automatic data processor.
2.2 This standard applies to word-serial transfers that involve the parallel transmission of up to, and including, 24-bits as a word between one of many sources and one of many acceptors of data.
2.3 This standard does not concern itself with the features, characteristics or requirements of the system inter-connection with the common controller, computer or other automatic data-processor, except in so far as these affect the operating conditions of the interface characteristics of the units.
