Co-Simulation Pspice - Matlab - Simulink

I simulated in Orcad an inverter, and I wanted that to Co-Simulate it in Matlab. The problem is that I get only '0' value on Simulink scope. The circuit in Orcad is (see first picture.) and the circuit in Simulink and the settings for it (see second picture.). Last picture is the result of simulation. The quiestion is: why my Output is always on 0 , I tought that the scope can't get the digital signals and I tried to get the values of variables on Matlab and plot them, but same result. Sorry for picture clarity.iables on Matlab and plot them, but same result
