Hello, I am new here and PLC's.

I am trying to create a project. When press the push button once Q1 works for 12 seconds and Q2 works at the 5th second and Q2 stops at the 10th second. How can I create this project? 

I attached the project I was trying to do. I will be glad if you can help.

I1 = Stop Button
