Five Parted Edge

Meaning

The Five Parted Edge is used to connect transitions and places. With this edge it is very easy to connect two nodes when you cannot draw a straight edge between them.

A petri net edge is directed. The direction depicts the flow of tokens.

Utilization

The Five Parted Edge is very versatile and can have many different shapes:

Input Boxes

When you select the shape, it will show you its available input boxes. The gray description texts show the meaning of those boxes.

To enter text, click a second time (after selecting the shape), now on the desired input box, and finally start typing to overwrite or press F2 to edit an existing text. After you have entered text, the gray descriptions will no longer be visible.

Condition:	The condition which must be fulfilled in order to pass this edge (a condition is only suitable if the source of the edge is a place and the sink is a transition).
Arc weight:	The number of tokens which pass this edge (i.e. a replacement for "arc weight" number of edges with the same source and sink).

(Note: These texts only appear when the FMC Support Tools >= 2.0 add-in is installed. With an older version or no installed add-in there will be colored boxes.)

Control Points

A1, A2 )	manipulate the shape of the edge Note: Both can be attached to other connection points like normal line ends. See section Hints below.
B )	moves the position of the condition text box
C )	moves the position of the arc weight text box

Hints

Fixed Control Points

The two manipulators A1 and A2 can be attached to connection points like normal line ends. This helps if you want them to stay fixed. In the example below, the top manipulator with a fixed position connected to the place will make a straight horizontal line from now on.
