Space engineering - SpaceWire protocol identification
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 applications. These protocols are covered by the ECSS-E-ST-50-5x series.
To distinguish between the various protocols a protocol identifier is used. This Standard specifies this protocol identifier.
This standard may be tailored for the specific characteristic and constrains of a space project in conformance with ECSS-S-ST-00.

Obstaja več komunikacijskih protokolov, ki se lahko uporabljajo v povezavi s standardom SpaceWire (ECSS-E-ST-50-12), za zagotovitev celovitega nabora storitev za uporabniške aplikacije v vesoljskih plovilih. Ti protokoli so zajeti v seriji standardov ECSS-E-ST-50-5x. Za razlikovanje različnih protokolov se uporablja identifikator protokolov. Ta standard določa ta identifikator protokolov. Ta standard se lahko prilagodi posameznim lastnostim in omejitvam vesoljskega projekta v skladu s standardom ECSS-S-ST-00.

Overview
EN 16603-50-51:2014 - "Space engineering - SpaceWire protocol identification" (CEN) defines the protocol identification scheme used to distinguish multiple communication protocols operating over a SpaceWire network. The standard specifies how a Protocol Identifier and an optional Extended Protocol Identifier are carried in SpaceWire packets, allocation and reserved values, addressing behavior at targets, and handling of unknown protocols. It is intended for tailoring per ECSS-S-ST-00 for project-specific constraints.
Key topics and technical requirements
Packet addressing
- A packet arriving at a target shall start with a single-byte logical address (the SpaceWire network may strip path addresses en route).
- Default logical address is 254 (0xFE); targets may choose to ignore this value or accept multiple logical addresses.
Protocol Identifier (PID)
- A single byte immediately following the logical address identifies the protocol.
- Value 0x00 is reserved to indicate an Extended Protocol Identifier.
- Value 0xFF (255) is reserved and shall not be used.
Extended Protocol Identifier (EPID)
- When used, the PID byte is 0x00 and the next two bytes form a 16-bit EPID, enabling up to 65,535 protocol identifiers.
- EPID values 0x0000–0x00FF are reserved and must not be used.
- If a target does not support EPID, packets with PID 0x00 must be discarded.
Unknown protocol handling
- Packets with unsupported PID or EPID shall be discarded; targets may keep counts of discarded packets for diagnostics.
Allocation ranges
- PID 1–239 (0x01–0xEF) are allocated by the SpaceWire working group (examples: RMAP = 1, CCSDS Packet Transfer Protocol = 2, GOES‑R = 238, legacy serial = 239).
- PID 240–254 (0xF0–0xFE) are project‑assignable (risk of conflicts if not coordinated).
- No EPIDs are currently allocated in the standard; consult the SpaceWire website for updates.
Applications and who uses it
- Applicable for spacecraft avionics, on‑board data handling, payload interfaces and satellite network design.
- Primary users:
- SpaceWire system architects and network engineers
- Onboard communications protocol designers (RMAP, CCSDS implementations)
- Satellite integrators, mission systems engineers and standards/compliance teams
- Firmware developers for routers, nodes and instruments that implement SpaceWire
