Bus-Capable Blocks

块s that support buses or arrays of buses can accept them as input, produce them as output, store them in memory, or perform a combination of these options. Block support for buses and arrays of buses can depend on block parameter settings.

This table describes whether a block supports virtual buses, nonvirtual buses, and arrays of buses.

Note

Buses that contain signals of enumerated data types do not pass through a block that requires a nonzero scalar initial value (such as aUnit Delayblock). Use a structure value to initialize signals with enumerated types.
