Question: same input output signal name in simulink

I want to make code below by model (or stateflow) using Code Generation   if( var > 10){ var = 10; }   In this case, upper 'var' is input of chart(or subsystem) and lower 'var' is output of chart.   So, it occurs signal complication if I use same variables name or I can't make same name of chart's input and output. I can make this if sentance by using two variables, but I hope to make this by using one.   Thanks for your help.

    Yeh It can be possible with Data store memory block.
     
    Make a Variable 'Var' in stateflow and change its scope to Data store memory .
     
    You can also control the variable storage class by resolving data store memory with simulink signal.
     
    The generated code looks like:
     
    /* Real-time model */
    RT_MODEL_Chart_T Chart_M_;
    RT_MODEL_Chart_T *const Chart_M = &Chart_M_;
    /* Model step function */
    void Chart_step(void)
    {
    /* Chart: '<Root>/Chart' */
    /* Re-use inputs */
    if (Var > 10) {
    /* NEW_PATTERN */
    Var = 10;
    }
    /* End of Chart: '<Root>/Chart' */
    }
