This clause specifies the information requirements for the
Cable
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
Cable_arm
schema and identifies the necessary external references.
EXPRESS specification:
*)
SCHEMA Cable_arm;

The following EXPRESS interface statement specifies the elements
imported from the ARM of another application module.

NOTE 1
The schemas referenced above are specified in the following
part of ISO 10303:

NOTE 2
See Annex C,
Figures

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.
A Cable_terminal is a type of
Part_terminal.
A Cable_terminal is a mapping of an instance of
Packaged_connector_component_interface_terminal
to specify an interface terminal for a cable. This mapping is maintained entirely in the Cable_usage_view.
If available, the connection_area shall be supplied.
The mapping provides support for establishing end-to-end continuity specification for a Cable.
EXPRESS specification:
*)
ENTITY Cable_terminal
SUBTYPE OF (Part_terminal);
SELF\Part_feature.associated_definition : Cable_usage_view;
mapped_terminal :
OPTIONAL
Packaged_connector_component_interface_terminal;
WHERE
WR1: SELF\Part_feature.associated_definition :=:
mapped_terminal\Component_feature.associated_definition\Assembly_component.occurrence_contexts[1].relating_view;
END_ENTITY;
(*
Attribute definitions:
associated_definition:
specifies the role of the Cable_usage_view for the Cable_terminal.
mapped_terminal:
specifies the role of the
Packaged_connector_component_interface_terminal
for the Cable_terminal. The mapped_terminal is the interface terminal on a connector component in the usage view that is being
assigned the role of the cable terminal.
The value of this attribute need not be specified.
Formal propositions:
WR1:
The associated_definition shall be the assembly of the mapped_terminal.
A Cable_usage_view is a type of
Part_usage_view.
A Cable_usage_view may provide detailed assembly data including location and orientation of connectors and location of cable centreline and
junctions using geometric models that are annotation models.
NOTE 1
The Cable_usage_view supports intellectual property protection. A design organization can control the amount of data they provide to a licensee
or purchaser by including only a specifically tailored set of data in a usage view.
NOTE 2
Shape information is provided by Physical_unit_3d_shape_model or by Physical_unit_planar_shape_model. Shape of connector is provided by Assembly_component_2d_shape_model or by Assembly_component_3d_shape_model. Shape of centreline curve is provided by annotated curve or by solid curve.
EXAMPLE 1
This data can include the information currently included in an interface control drawing (ICD).
EXAMPLE 2
The data in a Cable_usage_view does not include details of the cross-section wiring arrangement.
EXPRESS specification:
*)
ENTITY Cable_usage_view
SUBTYPE OF (Part_usage_view);
INVERSE
access_mechanisms : SET[1:?] OF Cable_terminal FOR associated_definition;
END_ENTITY;
(*
Attribute definitions:
access_mechanisms:
specifies an inverse relationship that specifies that the existence of the Cable_usage_view is
dependent on the existence of the Cable_terminal that specifies the Cable_usage_view as its
associated_definition. There shall be one or more Cable_terminal for a Cable_usage_view.
NOTE 3
A Cable_terminal is an application of the interface terminal of the Packaged_connector_component_interface_terminal. The Cable_terminal is provided for specification of the continuity specification of the Cable.
