Symbol Orientation

  • BelowBus
  • Vertical
  • VerticalFlipped
  • Horizontal 
  • HorizontalFlipped

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).
