This clause specifies the information requirements for the
Interface component
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
Interface_component_arm
schema and identifies the necessary external references.
EXPRESS specification:
*)
SCHEMA Interface_component_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
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 Interface_component is a type of
Physical_component
and a type of
Single_instance
used to provide an identified interface in the assembly.
EXAMPLE 1
Figure 1 illustrates an Interface_component and its role in the assembly, and that there may be multiple Interface_component in sequence.
EXAMPLE 2
Figure 2 of ISO/TS 10303-1636
illustrates a detail of an assembly drawing that shows a microcircuit plugged into a socket which is an Interface_component.

EXPRESS specification:

ENTITY Interface_component
SUBTYPE OF (Physical_component, Single_instance);
INVERSE
access_mechanism : SET[1:?] OF Physical_component_interface_terminal FOR associated_definition;
END_ENTITY;
(*
Attribute definitions:
access_mechanism:
an attribute is an inverse relationship that specifies that the existence of the Interface_component is dependent on the
existence of the Physical_component_interface_terminal that
specifies the Interface_component as its associated_definition. There shall be one or more Physical_component_interface_terminal for an Interface_component.
A Physical_component_interface_terminal is a type of
Physical_component_feature.
A Physical_component_interface_terminal is
one termination of an interface component.
EXAMPLE
An example of this is one terminal on a socket or connector, available for mating to a terminal of an external connector
or to a terminal of a component installed in the socket.

(*
Attribute definitions:
associated_definition:
an attribute that is inherited from Component_feature shall be redeclared as Interface_component for the Physical_component_interface_terminal.
This subclause specifies the ARM subtype constraint for
this module. The subtype constraint places a constraint on the
possible super-type / subtype instantiations.
The ARM subtype constraint and definition is
specified below.
The
physical_component_feature_subtypes
constraint specifies a constraint that applies to instances of
Physical_component_feature
and enforces the rule that its subtypes
Physical_component_terminal and Physical_component_interface_terminal
are exclusive.
