The are several valid symbol orientations. These include:
Some symbols appear the same whether they are above or below a bus.
Figure 1: Symbol Orientations to a Bus
Some symbols can be shown in their original orientation (Vertical) and can also potentially be rotated 180° from their original orientation (VerticalFlipped). The symbol appears in the same orientation whether it is above or below the bus.
Figure 2: Vertical Symbol Orientations
Similarly, some symbols have a horizontal orientation that occurs when the symbol is rotated 90° or 270°.
Figure 3: Horizontal Symbol Orientations
The orientations are symbol-specific (see table below).
