Hi, Is it possible to access data associated with a signal which is output of a bus creator in its structure form? For example I have two signals (signal1 and signal2) , I send them to a bus creator whose output is signal3. So Signal3 is now a structure. I have to access the data associated with signal1 and signal2 in s-function in following way. Signal1_Data = signal3. signal1; Signal2_Data = signal3.signal2;

Is it possible?

Thanks, Jagmohan

You can access the bus signal data in the s-function in the same way you have mentioned (ie in structure format)

Bus Input/Output support for s-function, using S-function builder is included from Simulink 7.3 (R2009a).

See a similar thread here.

Bus support is not available in MATLAB S-functions. Bus signals are supported in (Embedded) MATLAB Function blocks and C-MEX S-functions however.

I really need bus signal support in a level 2-M S-function. This should be supported... (Feature request??)

Any work around to work with a "struct-like" data type in an M S-function?
