Template: OASIS:EnvironmentObserved

This section specifies the template EnvironmentObserved.

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 EnvironmentObserved template.

The specification comprises the following sections:

NOTE    An explanation of a template and its specification is provided in the Template overview

The EnvironmentObserved template describes how to represent the fact an environment has been observed ((ObservedEnvironment)).

For instance, the temperature (measuredEnvironmentProperty) T=2C has been observed, and therefore the EnvironmentObserved can be linked to an EnvironmentDefinition, defining a "cold" environment when the temperature is in between 0C and 5C.

It can also be linked to the activity (measuringActivity) that performs the measurement in which we could find the meter (for instance) as a resource of this activity.

The SysML Block Definition diagram in Figure 1 shows how a activity is represented in the PLCS PSM.

Figure 1 -  Environment model

No templates have been explicitly defined as being related to the EnvironmentObserved template.

NOTE    The EnvironmentObserved template may make reference to other templates as part of the Parametric Diagram. These are not listed here.

Figure 2 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 output ports are defined for this template:

obsEnv (Block: Ap239Ap233Psm:ObservedEnvironment)
Enables the Block: Ap239Ap233Psm:ObservedEnvironment instantiated by this template to be referenced when the template is used.
obsEnv_vn (Block: Ap239Ap233Psm:ObservedEnvironmentVersion)
Enables the Block: Ap239Ap233Psm:ObservedEnvironmentVersion instantiated by this template to be referenced when the template is used.
obsEnv_view (Block: Ap239Ap233Psm:ObservedEnvironmentView)
Enables the Block: Ap239Ap233Psm:ObservedEnvironmentView instantiated by this template to be referenced when the template is used.

There are no constraints defined for this template.

This section describes the template's Parametric Diagrams. Each diagram details the pattern of templates and PLCS PSMTemplate objects that are required to represent the template EnvironmentObserved.

The public properties, i.e. those visible in the template's SysML block (See Figure 2) 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.
