I have an electronic pressure controller and I want to use my Analog output to control to 4 different pressures through 3 push buttons   High push button  - would send a 6 volt signal to EPR

                                                         Low Push button - would send a 3 volt signal to EPR

                                                         String-in  button would send a 4 volt signal to EPR  and after 3 seconds it would send a 4.2 volt signal.

Iam new at Logo 8 programing and  I would appreicate a ladder logic solution,

Thanks 
Dave D
