Application module: Assembly module with subassembly | ISO/TS 10303-1641:2019(E) © ISO |
This clause specifies the information requirements for the Assembly module with subassembly application module. The information requirements are specified as the Application Reference Model (ARM) of this application module.
NOTE 1 A graphical representation of the information requirements is given in Annex C.
NOTE 2 The mapping specification is specified in 5.1. It shows how the information requirements are met by using common resources and constructs defined or imported in the MIM schema of this application module.
This clause defines the information requirements to which implementations shall conform using the EXPRESS language as defined in ISO 10303-11. The following begins the Assembly_module_with_subassembly_arm schema and identifies the necessary external references.
EXPRESS specification:

SCHEMA Assembly_module_with_subassembly_arm;

NOTE 1 The schemas referenced above are specified in the following part of ISO 10303:
Assembly_module_design_arm ISO/TS 10303-1636
NOTE 2 See Annex C, Figures C.1and C.2 for a graphical representation of this schema.
This subclause specifies the ARM entities for this module. Each ARM application entity is an atomic element that embodies a unique application concept and contains attributes specifying the data elements of the entity. The ARM entities and definitions are specified below.
An Assembly_module_component is a type of Physical_component and a type of Single_instance. The Assembly_module_component represents the inclusion of a specific product version in the associated assembly.
NOTE 1 Assembly_module_component may be useful in a vertically integrated concurrent engineering environment, where full data sharing is allowed, as it permits visibility into the design definition of the component.
NOTE 2 An enterprise could use this capability in the case of co-design of assembly and integrated circuits.
NOTE 3 Hierarchical physical design does not require this capability, but this is the most explicit way to support hierarchical electrical traceability.
EXAMPLE Consider a daughter board instance as an Assembly_module_component. The design organization maintains explicit traceability between the design of the mother-board and the design of the daughter-board.

Attribute definitions:
derived_from: specifies the role of the Assembly_module_design_view for the Assembly_module_component.
usage_view: specifies the role of the Assembly_module_usage_view for the Assembly_module_component.
access_mechanisms: specifies an inverse relationship that specifies that the existence of the Assembly_module_component is dependent on the existence of the Assembly_module_component_terminal that specifies the Assembly_module_component as its associated_definition. There shall be two or more Assembly_module_component_terminal for an Assembly_module_component.
Formal propositions:
WR1: The name shall not be populated.
WR2: The Assembly_module_usage_view referenced by usage_view shall also be referenced by the definition of the Assembly_module_component_terminal that references the Assembly_module_component.
