SysPhS-1.1: Annex A.5: Humidifier: Naming not very consistent across parts, input/output Port name, value properties, or constraint parameters

The use of an additional «port» keyword on a Port is usually redundant and causes clutter. The use of an additional «port» keyword on a basic Property is an obsolete trick. Please don't imitate it even if you see it in some specification sample diagrams!

MagicDraw/Cameo: You can drag out a Property (or Port) from a Class or Block symbol to create an Association with the Property (or Port) as one end

There is no «port» stereotype keyword for Port or Property in UML-2.5.1 or SysML-1.6. It is assumed to be introduced in some SysML and SysPhS specification diagrams as a custom or user-defined stereotype for special illustration purposes.

SysPhS-1.1: Apparent use of part Property with «port» keyword (instead of standard SysML Port) leads to property path symbols appearing inside the boundary of context blocks (instead of within a Port symbol on the boundary) in IBDs and Parametric Diagrams

Webel vs SysPhS-1.1: Recommend use standard SysML Ports instead of block part property with «port» keyword

09:02: Ports - The basics

Slide kind

If the general ports had both behaviors and internal binding connectors, then both specializations would be invalid.

Source

Unstereotyped ports have the basic functionality of stereotyped ones, including flow properties and nested ports, so they can be used as long as the modeler is not concerned with the distinction between proxy and full, and the constraints they impose.

Source

For example, if the port types on the general block in Figure 9-7 had behaviors defined, then the proxy specialization would be invalid. If the general ports had binding connectors to internal parts, then the full specialization would be invalid.

Source

Unstereotyped ports do not commit to whether they are proxy or full, and do not prevent or dictate future application of the stereotypes, except for ports that violate constraints of the stereotypes.

Source

Figure 9-7 happens to use unstereotyped ports on a general block distributed to users, and stereotyped ports on its specializations for implementation, but the modelers might have not used stereotypes at all, if they did not care whether the model met ...

Source

Modelers can apply stereotypes for proxy and full ports at any stage of model development, or not all if the stereotype constraints are not needed.

Source

The stereotypes of proxy and full ports might be elided in these cases to simplify diagrams.

Source

Using existing blocks with ports only requires knowing the port types, because they define the features available for linking or communication with those ports via connectors.

Source

Modelers have the option of applying stereotypes for proxy and full ports to indicate whether ports are specifying features of their owners and internal parts (proxy), or for themselves separately (full). This is a concern when defining ports, rather ...

Source

Modelers can choose between proxy or full ports at any time in the development lifecycle, or not at all, depending on their methodology.

Source

Proxy and full ports support the capabilities of ports in general, but these capabilities are also available on ports that are not declared as proxy or full.

Source

In either case, users of a block are only concerned with the features of its ports, regardless of whether the features are surfaced by proxy ports, or handled by full ports directly.

TRAIL: The SysML-1.6 Hybrid SUV sample and specification diagrams in MagicDraw/Cameo (with annotations) [UNDERGOING UPDATE to SysML1.7]

Typing a "standard" Port by an InterfaceBlock or ~InterfaceBlock IS allowed AND can be useful; typing a FullPort by an InterfaceBlock or ~InterfaceBlock is formally allowed but not so useful, because it would have no parts or behaviors to do anything.

UML/SysML: In Internal Block Diagrams: Consider hiding the name of a named Port or Property in a Diagram if its Type is sufficient to indicate its role.

SysML: Typing a Port by an InterfaceBlock or ~InterfaceBlock does NOT imply that the Port is a ProxyPort (but ProxyPort must be typed by an InterfaceBlock or ~InterfaceBlock)

Figure D.21 is an incomplete first step in the refinement of this bus architecture, as it begins to specify the flow properties for InternalCombustionEngine, the Transmission, and the ElectricalPowerController.

For purposes of example, the ports, flows, and related point-to-point connectors in Figure D.19 are being refined into a common bus architecture. For this example, ports with flow properties have been used to model the bus architecture.
