Process → Link Process and Buffer (New Arrow) |
By using the toolbar buttton
Create New Arrow or the menu item Process/Buffer → New → Arrow
you can connect a process and a FIFO buffer (see Figure 17).
For this you have to select the button or
the menu item first. Afterwards you can choose the start object (process or buffer) by selecting it with
the left mouse button. While keeping the mouse button pressed you can move the cursor to the
target object. After you have released the mouse button a new arrow will be drawn (see Figure 18).
Figure 17
In this training module each process has four connection ports. One
at the top, one at the bottom, one on the left side and one on the right side of the process symbol.
The ports can be input or output ports. A FIFO buffer on the other hand has one input port and one output
port. The location of the input and output port depends on the transfer direction of the buffer.
If you have selected two objects where a connection is not possible, no arrow will be drawn.
Connections are not allowed between two processes or two buffers, respectively.
Furthermore, no connection will be created if one of the selected objects has no
free ports.
Figure 18
You can select an arrow by selecting it with the left mouse button.
The currently selected buffer has highlighted ports
(as shown in Figure 19).
Figure 19
By selecting the toolbar button Delete Process, Buffer or Arrow in the network editor
or the menu item Process/Buffer → Delete you can remove the currently selected arrow
from the network editor.
By selecting the toolbar button Show/Hide Parameters in the network editor or the
menu item Process/Buffer → Show Parameters
you can open the arrow parameter frame (see Figure 20).
Figure 20
You can use the arrow parameter frame for changing the port at the start object or at the
target object.
With the toggle button group
select Port: you can choose a new port for the connection at the start object
or at the target object, respectively.
By selecting the button
Ok of the parameter frame you can confirm the current settings and the connection
will be updated in the network editor. The parameter frame will be closed.
For closing the parameter frame without an update of the connection you can use the
the button Cancel of the parameter frame.
In the next subsection you will find details about the execution of the process networks
and the control of the visualisation.
