Ports

In this section all port related information needed to satisfy the Exchange Electrical Model - Systems will be described.

A port is a logical mechanism that is used to enable an element to connect to another element. A distribution port is a type of port that is used for connecting together distribution flow elements such as electrical elements.
A distribution element may have one or more points at which it connects to other elements. A distribution port is located at a point where a connection can occur. The location of the port is determined in the context of the local coordinate system of the element to which it belongs.
A port is defined as belonging to a particular element through a port to element connection relationship.

Generally for Ports

The information that is captured concerning a distribution port includes the following.

Information Needed	Man	Opt	Rec	Actor Supplying	Functional Part
Port name and description				Electrical Design	[Model Distribution Port (cable) (FP)] OR [Model Distribution Port (cable carrier) (FP)]
Placement of the port in the context of the local coordinate system of the element to which it belongs				Electrical Design	[Model Distribution Port (cable) (FP)] OR [Model Distribution Port (cable carrier) (FP)]
Shape representation of the port; for a distribution system this would typically be a point.				Electrical Design	[Model Distribution Port (cable) (FP)] OR [Model Distribution Port (cable carrier) (FP)]
Relationship between the port and the element for which it provides a connection opportunity				Electrical Design	[Model Distribution Port (cable) (FP)] OR [Model Distribution Port (cable carrier) (FP)]
Direction of flow through the port				Electrical Design	[Model Distribution Port (cable) (FP)] OR [Model Distribution Port (cable carrier) (FP)]

Properties

Additional properties that should be defined for ports are as follows.

Information Needed	Man	Opt	Rec	Actor Supplying	Functional Part
The number of the port in the context of the element				Electrical Design	[Model Distribution Port (cable) (FP)] OR [Model Distribution Port (cable carrier) (FP)]
The type of connection made at the port				Electrical Design	[Model Distribution Port (cable) (FP)] OR [Model Distribution Port (cable carrier) (FP)]

Connection

A connection describes the connected relationship made between two ports.

Information Needed	Man	Opt	Rec	Actor Supplying	Functional Part
For connections made between ports, the values of flow direction for each port must match. If the flow direction of the relating port is a SOURCE (outgoing), the flow direction of the related port must be SINK (incoming). If the flow direction of the relating port is SOURCEANDSINK, the flow direction of the related port must also be SOURCEANDSINK				Electrical Design	Connect Ports (FP)
