Corners are used to force the routing of connection lines, as the FBD editor imposes a default routing only between two pins or user defined corners. All variable symbols and constant expressions are entered in FBD diagrams using small boxes. Press the following button in the FBD toolbar for inserting a corner on a line:
|Insert corner: In this mode, the mouse is used for inserting a user defined corner on a line.|
You can drag a new line from an output pin to an empty space. In that case the editor automatically finished the line with a user defined corner so that you can continue drawing the connection to the wished pin and force the routing while you are drawing the line.
Corners can then be selected and moved to change the routing of existing lines.
