EDS and Common DoT Relationships and Structure
Generic Functional Interface Generic Functional Interface All Functional Interfaces, DACPs and DAPs make use of terms from the Common DoT They may also make use of manufacturer-specific terms, but these are composed of more simple terms from the Common DoT Device EDS Functional Interface Functional Interface Functional Interface Some Functional Interfaces are Generic Functional Interfaces, i.e. completely standard Some Functional Interfaces extend Generic Functional Interfaces with manufacturer-specific extensions Other Functional Interfaces are completely manufacturer-specific DACP DAP DAP is defined in terms of using subnetwork-specific Subnetwork Services, e.g. Memory Access Service using ECSS 1553 Get/Set Services Subnetwork Service Subnetwork Service Subnetwork Service 12/10/12 SOIS APP WG Fall 2012

XML Representation Common DoT Generic Functional Interface
The Common DoT XML file is managed by SANA The Generic Functional Interfaces’ XML files are expected to eventually be managed by SANA imports Generic Functional Interface Generic Functional Interface Generic Functional Interface imports Each device has it’s own EDS An EDS may be incomplete, e.g. a device EDS supplied by a manufacturer need not have any Functional Interfaces. Conversely an EDS used for device simulation in software testing may only have a Functional Interface uses imports Device EDS EDS XML Schema The EDS XML Schema file is managed by SANA uses 12/10/12 SOIS APP WG Fall 2012

Actions – Information Material
Complete Common Overview Section based on agreed structure (Ray Krosley/Stuart Fowell) for mid Nov 2012 Add “EDS usage in Layered Architecture” picture to Common Overview Section Explain different usage of EDS, related to “EDS usage in Layered Architecture” picture for end of Nov 2012 Physical Device to OBSW (Stuart Fowell) RIU/ Aggregated Device (Glenn Rakow supported by Felice Torelli & Chris Taylor) What is the SOIS architecture from OBC -> RTU -> devices?, What EDSs are here? How do they combine? Build upon section added to Green Book, Use 1451 as example, Include e.g. thermistors, current sensors, magnetic torque bar, etc Intelligent Device e.g. SPA ASIM (Ray Krosley) Software Bus Adaptor (Jonathan Wilmot) Spacecraft TM/TC – only mention this, don’t explore it as this is MOIMS territory 12/10/12 SOIS APP WG Fall 2012
