I have a scenario in which I have to connect to client once and then need to use same connection object for further processing. I am planning to connect client in START function in S-function and in same block I want to declare variable which can be access from OUTPUT block for further processing. So please suggest me some way to achieve this or give some reference example. Thanks....

You will need to set up a "DWork" variable that gets assigned a value in the mdlStart() function and can then be used in the mdlOutput() function. This link gives details on creating and using a DWork variable in an s-function.

Thanks for the answer. I have tried these methods already but it is working for just int,double or boolean data types. But I have custom class object and I want to pass this object via Dwork variable. While doing so it throws an error even if I use "inherited" data type. So please guide me how to handle such class object in s-function in matlab file. I am not using c/c++ file to do this. Please guide me on this. Thanks in advance.
