IEC 60935 Ed. 2.0 b:1996

Defines a modular data-bus system for data acquisition, data processing and control. Gives mechanical, signal, electrical and protocol specifications that are sufficient to assure compatibility between units from different sources of design and production. Applies to systems consisting of modular electronic instrument units that process or transfer data or signals, normally in association with computers or other automatic data processors. Is used for nuclear instrumentation and control systems and other applications. See IEC 61052.
