Dear Félix Díaz,
Thank you very much.
Suggest to compile these codes and RUN by using Basic Compiler. Control Panel will be displayed from where output relays can be controlled directly by using U and Q keys. You can see the control panel from

Would like to know about designing this control panel in Visual Basic.
