This section specifies the template system_element.
NOTE
The template has been defined in the context of
UK_Defence.
Refer to the business context for details of related templates.
NOTE
An explanation of a template and the associated instantiation path is
provided in the
Template overview
section.
This template describes how to represent the UK_Defence concept of a system breakdown element
in terms of PLCS model elements (templates, entities, and reference data).
This information object represents a system of the product.
This information object represents a system of the product.

The EXPRESS-G diagram in
Figure
2
shows the templates and EXPRESS entities that are required
to represent the template
"system_element".
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

The following input parameters are defined for this template:
The identifier of the system element.
The description of the system element.
The name of the system element.
type (Default=System_element_type,Type='CLASS')
The type of the physical breakdown item.
The identifier of the organization that owns the id. It is assumed that this will be of type Organization_identification_code
and not an Organization name.
The breakdown version that contains this element.
The identifier of the functional breakdown version.
The following reference parameters are defined for this template:
Allow the
System_element
entity instantiated in this path to be referenced when this template is used.
Note: The
System_element
entity can be referenced in a template path by:
%^target = $system_element.sys_elem%
Allow the
System_element_version
entity instantiated in this path to be referenced when this template is used.
%^target = $system_element.sys_elem_vn%
%^target = $system_element.sys_elem_def%
%^target = $system_element.def_cntxt%
%^target = $system_element.sys_cntxt%
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.

The instance diagram in Figure
4
shows an example of the EXPRESS entities and templates that are instantiated by the template:
/system_element(id='8397', description='flow monitoring', name='HVAC 357', type='Electromechanical', version='version A08', source_organization='6421')/
(an illustration of the consolidated system_element template is shown in
Figure
5 below.)

The instance diagram in
Figure
5
shows the graphic symbol for the template that is to be
used in other instance diagrams. The example template is:
/system_element(id='8397', description='flow monitoring', name='HVAC 357', type='Electromechanical', version='version A08', source_organization='6421')/

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