DIN EN 16603-70-32:2014-12

The procedure is the principal mechanism employed by the end-user to control the space system during pre-launch functional testing and post-launch in-orbit operations. This standard identifies the requirements to be satisfied by any language used for the development of automated test and operation procedures. It also defines a reference language that fulfils these requirements. This language is called the "procedure language for users in test and operations (PLUTO)". This standard specifies: the capabilities of the language used for the definition of procedures for space system testing and operations; the PLUTO language. Clause 4 defines the context in which procedures operate. Clause 5 contains the requirements for the procedure language. Annex A specifies the PLUTO language. This includes: the "building blocks" that constitute procedures and the role that each of these building blocks plays in achieving the overall objectives of the procedure; the dynamic aspects of procedures, namely the execution logic of each building block and execution relationships between these blocks; the syntax and semantics of the language itself. Annex B specifies the engineering units to be supported by the procedure language. Annex C specifies the mathematical, time and string functions to be supported by the procedure language. This standard may be tailored for the specific characteristics and constraints of a space project in conformance with ECSS-S-ST-00. This document (EN 16603-70-32:2014) has been prepared by Technical Committee CEN/CLC/TC 5 "Space", the secretariat of which is held by DIN (Germany). This document has been developed to specifically cover space systems and therefore has precedence over any European Standard since it covers the same scope but with a wider domain of applicability (for example aerospace).
