The IEC developed their own standards in parallel with the IEEE, with IEC 60625-2-1993 (IEC 625). In 2004, the IEEE and IEC combined their respective standards into a "dual logo" IEEE/IEC standard IEC 60488-2-2004, Part 2: Codes, Formats, Protocols and Common Commands, [11] replaces IEEE 488.2-1992 and IEC 60625-2-1993.

The AS-Interface has been an international standard according to IEC 62026-2 since 1999. AS-Interface is a networking alternative to the hard wiring of field devices. It can be used as a partner network for higher level fieldbus networks such as Profibus , DeviceNet , Interbus and Industrial Ethernet , for whom it offers a low-cost remote I/O ...
IEC standards cover a vast range of technologies within electrotechnology. The numbers of older IEC standards were converted in 1997 by adding 60000; for example IEC 27 became IEC 60027. IEC standards often have multiple sub-part documents; only the main title for the standard is listed here. IEC 60027 Letter symbols to be used in electrical ...
For existing safety instrumented systems (SIS) designed and constructed in accordance with codes, standards, or practices prior to the issuance of this standard (e.g. ANSI/ISA 84.01-1996), the owner/operator shall determine and document that the equipment is designed, maintained, inspected, tested, and operated in a safe manner.
Piping and instrumentation diagram of pump with storage tank. Symbols according to EN ISO 10628 and EN 62424. A more complex example of a P&ID. A piping and instrumentation diagram (P&ID) is defined as follows: A diagram which shows the interconnection of process equipment and the instrumentation used to control the process.
Manual: Performed by the programmer, e.g. by adding instructions to explicitly calculate runtimes, simply count events or calls to measurement APIs such as the Application Response Measurement standard. Automatic source level: instrumentation added to the source code by an automatic tool according to an instrumentation policy.
The code set includes all units defined in ISO 1000, ISO 2955-1983, [3] [a] ANSI X3.50-1986, [4] [b] HL7 and ENV 12435, and explicitly and verifiably addresses the naming conflicts and ambiguities in those standards to resolve them.
The standard was revised in 1987, and redesignated as IEEE 488.1 (IEEE 488.1-1987). These standards formalized the mechanical, electrical, and basic protocol parameters of GPIB, but said nothing about the format of commands or data. In 1987, IEEE introduced Standard Codes, Formats, Protocols, and Common Commands, IEEE 488.2.
