ARCH.057 Model non-payload data on external interfaces

GoalComplete the characterisation of external interfaces by modelling data for layers below application
Requirements met by this process step

EN 50126-1 7.3.2.1 b) and c)

ISO 15288 6.4.4.3 c 1)

Inputs

AMOD-114 System interface definition

AMOD-115 External interface behaviour

Outputs

AMOD-112 System data objects [S.CDB]

AMOD-113 System exchange items [S.CDB]

Methodology

Based on the interface layers identified in ARCH.158 Model external interface layers, capture the necessary exchange information in their own independent instances of AMOD-112 and AMOD-113 as appropriate.

This includes packet structure, header definitions etc. for each layer of an interface.

For more guidance see methodology on ARCH.054 Model data flowing between system functions.

Tools and non-human resourcesTeam for Capella
