You need to reiterate the exact sequence of events you are looking to achieve.
Start - stop, Limit SW - PB etc.

This works on the simulator, relatively easy fix!

1/ The Stop switch X1 has to be a P.B. of the N.C. variety to work, if it is a N.O. type then you have to change the X1 in rung 1 to a NC function.
2/ You do not show a M0 N.O. contact on the L.H. rail just ahead of rung #6.
Do you not have a Monitor function in the PLC S/W so that you can visibly monitor the actual ladder as it runs??
The program shown runs fine in a FX0n, I suspect it is because of what is explained in 1/ to be the cause.
