We generate C code through AUTOSAR and Simulink Coder for Simulink Model. We send signals in Simulink through AUTOSAR interface outport with DataAccessMode: ExplicitSend. We generate code through MATLAB script:

%Check model is loaded
load_system('ModelName');
% Generate code
rtwbuild('ModelName');

We want to implement safety through return value of Rte_Write, RTE_E_OK.

Currently, the generated C code is:

Rte_Write_PortName(&rtb_bus_creator_kk);

We want the generated C code to be similar to:

Consider a provided port, ra, containing a data element val of type SInt16 with the isQueued attribute set to “false”.

Std_ReturnType e = Rte_Write_ra_val(self, 23);
if (e == RTE_E_OK)
{
/* Transmission okay */
}
else{
    /* Transmission failed. Execute safety*/   
    }
