how can i access signals on a bus in simulink ?

I'he tried to read some signals in simulink , but one of them is a bus and it display a error. And don't have permission to change the simulink block

the bus is virtual one, and it is inside of one subblock on low level, which outputs the data into a big one..(I have like 7 levels ) and I don't have permission to modify the block,..i have to test only the outputs of the entire block .

Use the "Bus Selector" block to get the signals you are interested in.

From the documentation:

Bus Selector: Select signals from incoming bus

Library: Signal Routing

Description: The Bus Selector block outputs a specified subset of the elements of the bus at its input. The block can output the specified elements as separate signals or as a new bus.
