Error T1: There is no template_proxy in the capability representing_parts for the template representing_interface_connection

This section specifies the template representing_interface_connection.

NOTE The template has been defined in the context of the capability representing_parts which provides an overall description of the relevant parts of the ISO 10303-239 information model and a description of related templates.

NOTE An explanation of a template and the associated instantiation path is provided in the Template overview section.

Description

This template describes how to represent an interface connection.

EXAMPLE The connective relationship between two connectors that belong to two connected pipes.

Model diagrams

The EXPRESS-G diagram in Figure 1 shows the templates and EXPRESS entities that are required to represent the template "representing_interface_connection". The text highlighted in blue shows the template parameters.

The graphic for the template to be used in other EXPRESS-G diagrams is shown in Figure 2 below.

Input parameters

The following input parameters are defined for this template:

intrf_connxn_id (Type='STRING')

The identifier of the interface connector occurrence.

intrf_connxn_id_class_name (Default=Interface_connection_identification_code,Type='CLASS', Optional)

The name of the class used to classify the identifier assigned (using Identification_assignment ) to the interface connector occurrence.

The following classes and their sub-classes can be used:

classifications: "Interface_connection_identification_code" (urn:plcs:rdl:std:Interface_connection_identification_code)

intrf_connxn_id_ecl_id (Default=urn:plcs:rdl:std,Type='URN', Optional)

The identifier of the External_class_library that holds the definition of the External_class used to classify the identifier of the interface connector occurrence.

intrf_connxn_org_id (Type='STRING')

The name or identifier of the organization that is responsible for the identifier of the interface connector occurrence.

intrf_connxn_org_id_class_name (Default=Organization_name,Type='CLASS', Optional)

The name of the class used to classify the identifier of the organization that is responsible for the identifier of the interface connector occurrence.

The following classes and their sub-classes can be used:

classifications: "Organization_identification_code" (urn:plcs:rdl:std:Organization_identification_code), "Organization_name" (urn:plcs:rdl:std:Organization_name)

intrf_connxn_org_id_ecl_id (Default=urn:plcs:rdl:std,Type='URN', Optional)

The identifier of the External_class_library that holds the definition of the External_class used to classify the identifier of the organization that is responsible for the identifier of the interface connector occurrence.

connected_intrf_occ (Type= 'ENTITY (Interface_connector_occurrence)' )

connecting_intrf_occ (Type= 'ENTITY (Interface_connector_occurrence)' )

Reference parameters

The following reference parameters are defined for this template:

intrf_connxn_id(Type='ENTITY (Identification_assignment)')

Allow the Identification_assignment entity instantiated in this path to be referenced when this template is used.

Note: The Identification_assignment entity can be referenced in a template path by:

%^target = $representing_interface_connection.intrf_connxn_id%

where target is the parameter to which the Identification_assignment is bound.

intrf_connxn(Type='ENTITY (Interface_connection)')

Allow the Interface_connection entity instantiated in this path to be referenced when this template is used.

Note: The Interface_connection entity can be referenced in a template path by:

%^target = $representing_interface_connection.intrf_connxn%

where target is the parameter to which the Interface_connection is bound.

Uniqueness constraints

The following parameter combinations specify a uniqueness constraint:

Unique constraint: Unique interface_connection

Each instance of the entity (Interface_connection) within the data set shall be uniquely identified by a combination of the following parameters on this template (representing_interface_connection) namely: intrf_connxn_id, intrf_connxn_id_class_name, intrf_connxn_id_ecl_id, intrf_connxn_org_id, intrf_connxn_org_id_class_name, intrf_connxn_org_id_ecl_id.
The instance is referenced by the following template parameter: intrf_connxn.

Instantiation path

The instantiation path shown below specifies the entities that are to be instantiated by the template.

A description of templates and the syntax for the instantiation path is provided in the Templates Help/Information section.

-- Interface_connection
Interface_connection
%^intrf_connxn = Interface_connection%
Interface_connection.id = '/IGNORE'
Interface_connection.description = '/IGNORE'
Interface_connection.connection_type = '/IGNORE'
Interface_connection.connected -> @connected_intrf_occ
Interface_connection.connecting -> @connecting_intrf_occ

-- Identify the Interface_connection
/assigning_identification(
    items=^intrf_connxn,
    id=@intrf_connxn_id,
    id_class_name=@intrf_connxn_id_class_name,
    id_ecl_id=@intrf_connxn_id_ecl_id,
    org_id=@intrf_connxn_org_id,
    org_id_class_name=@intrf_connxn_org_id_class_name,
    org_id_ecl_id=@intrf_connxn_org_id_ecl_id )/

-- Ref parameter for the Interface_connection indentification
%^intrf_connxn_id = $assigning_identification.id_assgn%

The following entities are instantiated with attributes as specified:

Entity in path	Value	Inherited from
Interface_connection.id	'/IGNORE'	—
Interface_connection.description	'/IGNORE'	—
Interface_connection.connection_type	'/IGNORE'	—

Instance diagrams

The instance diagram in Figure 3 shows an example of the EXPRESS entities and templates that are instantiated by the template:

/representing_interface_connection(intrf_connxn_id='IC001', intrf_connxn_id_class_name='Interface_connection_identification_code', intrf_connxn_id_ecl_id='urn:plcs:rdl:std', intrf_connxn_org_id='Interfaces Ltd', intrf_connxn_org_id_class_name='Organization_name', intrf_connxn_org_id_ecl_id='urn:plcs:rdl:std', connected_intrf_occ='@46', connecting_intrf_occ='@1')/

(an illustration of the consolidated representing_interface_connection template is shown in Figure 4 below.)

Characterizations

No common characterizations of the template representing_interface_connection have been identified. However, the ISO 10303-239 EXPRESS model may enable other assignments to the entities instantiated by the template.
