35、-12 EN 16603-50-52:2014 (E) 7 Foreword 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. This standard (EN 16603-50-52:2014) originates from ECSS-E-ST-50-52C. This European Standard shall be given the status of
36、 a national standard, either by publication of an identical text or by endorsement, at the latest by March 2015, and conflicting national standards shall be withdrawn at the latest by March 2015. Attention is drawn to the possibility that some of the elements of this document may be the subject of p
37、atent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association. This document has been developed to cover specifically space
38、systems and has therefore precedence over any EN covering the same scope but with a wider domain of applicability (e.g. : aerospace). According to the CEN-CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Aust
39、ria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Swede

DIN EN 16603-50-52:2014-12 EN 16603-50-52:2014 (E) 8 1 Scope There is a number of communication protocols that can be used in conjunction with the SpaceWire Standard (ECSS-E-ST-50-12), to provide a comprehensive set of services for onboard user applicat
41、ions. 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 these protocols that works over SpaceWire. The aim of RMAP is to support reading from and writing to me
42、mory 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 characteristic and constrains of a space project in confor
43、mance with ECSS-S-ST-00.

For dated references, subsequent amendments to, or revision of
44、 any of these publications do not apply. However, parties to agreements based on this ECSS Standard are encouraged to investigate the possibility of applying the more recent editions of the normative documents indicated below.
