This section specifies the template FunctionalElement.
The specification comprises a SysML Block that represents the template and an
associated Parametric Diagram that defines the templates and
PLCS PSMTemplate objects
instantiated by the FunctionalElement template.
The specification comprises the following sections:
- Section Description provides a
description of the template;
- Section Template Block specifies the SysML
Block that represents the template;
- Section Template Properties specifies
the properties, i.e. the SysML Part, Reference and Value properties of the
templates SysML Block;
- Section Template Output Ports
specifies the SysML Output Ports of the templates SysML Block. These bind to the
templates and PLCS PSM objects
instantiated by the FunctionalElement template as
described in section Template
Parametric Diagram;
- Section Template Constraints specifies
the constraints on PLCS PSMTemplate objects instantiated by the
FunctionalElement template;
- Section Template Parametric
Diagram specifies the templates and PLCS PSMTemplate objects instantiated by the
FunctionalElement template;
- Section Instantiated blocks specifies
the templates and PLCS PSMTemplate objects instantiated by the
FunctionalElement template and bound to private
parts of the template;
- Section Default instances species the
instances that have been instantiated in the template. These are used to set
the default value of blocks.
- Section Constraint blocks identifies the
constraint blocks that have been specified in this template;
- Section Example data
provides example XML data sets that have been instantiated in accordance
with this template.
NOTE
An explanation of a template and its specification is provided in
the
Template
overviewThe FunctionalElement template describes how to represent a position or element in
the functional structure, e.g. breaking, propulsion, or communication function. These
functional structure elements are often used in fault finding. May also be called
"fault location code" or "feature".
No templates have been explicitly defined as being related to the FunctionalElement template.
NOTE
The FunctionalElement template may make reference
to other templates as part of the Parametric Diagram. These are not listed
here.
Figure 1 shows the SysML Block that represents the template. The Block is an abstraction
representing a pattern of templates and PLCS PSMTemplate objects.
The properties, i.e. the SysML Block Part, Reference and Value properties, of the
template's SysML Block are described in the Template
Properties section.
The output ports shown on the template's SysML Block are described in the template output ports section.
The SysML Parametric diagrams for the template Block are shown in template parametric diagram section.

The following SysML Part, Reference, and Value properties are defined for this template:
References:
breakdown [1] (Template: SwedishDefence:
FunctionalBreakdown)
Relationship to the functional structure that contains the functional structure element.
parent [0..1] ()
Relationship to the parent in the functional breakdown structure.
Parts:
functionalElementName [1] (Template: OASIS:
Name)
Name of the functional element
The reference data used in Template: OASIS:
Name is restricted as follows:
RDL constraint 1:functionalElementName constraint
The reference data for:
OASIS:Descriptor.classifiedAs -> ExternalOwlClass.class
is restricted to the following class or a subclass:
The following output ports are defined for this template:
There are no constraints defined for this template.
This section describes the template's Parametric Diagram. The diagram details
the pattern of templates and PLCS PSMTemplate objects that are required to
represent the template FunctionalElement.
The public properties, i.e. those visible in the template's SysML block (See Figure 1) are shown on the left of a
Parametric Diagram.
NOTE
Restrictions on the reference data to be set on the public properties is
defined in the
Template Properties section.
The output ports are shown on the right of a Parametric Diagram.
PLCS PSM
objects are shaded khaki and
Templates
are shaded light green in a Parametric Diagram.
