The problem in this model comes from using the communication components. Solving the problem can be done using following steps:
1-Copy the control blocks from the control sub-block and paste them in the main page.
2- delete the control sub-block after taking the control block from it.
In other word, put all your model blocks in one page. Then, run your model. once your system works properly, use the sub-model feature in your system.
