Rung 2:11 sets a variable N30:8 to 1 when an Auto mode restart occurs.
This sets up a station status reset in the next rung.

Rung 2:13 includes the Simulation Sequencer driven by the timer in rung
2:14. Rung 2:13 also sets the currently selected station status to “On”, and
the previous station status to “Complete” as the sequencer increments
through the 57 steps.
