Create the Auto Mode Rung
When Rung 2:3 is energized, the Auto mode bit latches and the sequencer
resets to its safe state (position 0). When the sequencer increments its
position above Step 0, the Scrolling List cursor will be controlled by the
PLC via the Sequencer Position Word Move to the Cursor Control
Address, and the Manual Cursor List buttons are disabled automatically.
