Diagram 133: Multiple Routes without Nodes
Diagram 133 shows a much more clear structure. It has still some drawbacks, though.
In total 16 routes are to be created and at each point of the lines there are at least 4
routes, that overlay each other, which makes it difficult, to select the right route, if necessary.
Graphical problems like these are solved with the help of nodes. These are additional
elements in the block diagram, that can help to reduce the complexity of a block diagram
and that can be used to create a clear structure. Nodes can be used in all cases,
where multiple blocks are to be connected with each other.
Nodes are used like blocks with regard to drawing in the block diagram. They are represented
by small rectangles and look like “small blocks”. Like blocks they can be
linked to multiple elements on both sides. This is shown in the following diagram:
Diagram 134: Multiple Routes with Nodes
The node shown in Diagram 134 connects to 4 routes on both sides. The resulting structure
is very clear now and it can be clearly seen, which routes connect which two
blocks. The node additionally helped here to reduce the number of necessary routes
from 16 to 8. This was possible by splitting each route into two parts.
