Stop Sequence

I strongly recommend that you do NOT use conditional subroutines. This is not only poor programming practice with ladder logic, but it will leave coils in limbo with unpredictable results.

Also, use transition contacts when calling HMI screens.

I want the STOP Button to reset the operation of the PLC to start afresh from where it started during START Command which it is NOT achieving except, I use ''SB-24'' in NET 7.  It happens when I use the SB-24 (Initialize and Reset PLC (Set to cause PLC Reset and to Initialize all operands to 0) which is not a good practice.  See the updated file attached.

Other than this, the sequence goes very well.
