DIN EN 16603-50-52:2014-12

There are a number of communication protocols that can be used in conjunction with the SpaceWire Standard (ECSS-E-ST-50-12) in order to provide a comprehensive set of services for onboard user applications. To distinguish between the various protocols a protocol identifier is used, as specified in ECSS-E-ST-50-51. This Standard specifies the Remote Memory Access protocol (RMAP) which is one of the protocols that works via SpaceWire. The aim of RMAP is to support reading from and writing to memory in a remote SpaceWire node. RMAP can be used to configure a SpaceWire network, control SpaceWire nodes and to transfer data to and from SpaceWire nodes. RMAP is specified in this Standard. 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 16603-50-52:2014) 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).
