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.
The following Part, Reference, and Value properties are defined for this template:
