Functional InterfaceFunctional InterfaceSome 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

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

DAP is defined in terms of using subnetwork-specific Subnetwork Services, e.g. Memory Access Service using ECSS 1553 Get/Set Services

The Common DoT XML file is managed by SANA

The Generic Functional Interfaces’ XML files are expected to eventually be managed by SANA

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
