What do you mean it doesn't work? In the pictures, the coils work as they should....

Did you go into PLC Parameters and set the programs to run? By default, one program called MAIN will run without parameter settings. When you create more than one program, you must go into the PLC Parameters, on the Program tab, and set each program as a scan type program. If you had put this in a PLC and not the simulator, you would have a 2501 Can't Execute Program error because of the parameters not being set.
