Unlike virtual buses, which can combine signals that have different sample times, all of the signals in a nonvirtual bus must have the same sample time.
To group signals with different sample times in a nonvirtual bus, make the sample times of the input signals the same by inserting Rate Transition blocks.
Suppose a model creates a nonvirtual bus using a Bus Creator block. To standardize the sample time of the input signals, the model uses three Rate Transition blocks before the Bus Creator block.
Suppose another model converts a virtual bus to a nonvirtual bus using a root-level Outport block. To standardize the sample time of the elements of the virtual bus, the model uses a single Rate Transition block before the Outport block.
Alternatively, specify the same sample time at each block that generates an element of the bus.
