Operations
After the motion to the pounce position is called, the step will increment to
Step 30 where the Conveyor Sync Start instruction is executed (Fig.6-19
"Move to Conveyor Pounce Position"). As mentioned earlier, this
instruction will wait for an object to pass the photo eye and move to the
Conveyor Start Position before turning on its Sts_DN bit. This instruction
also has a Sts_OL bit which will turn on only if the object has moved past
its Max Start Position. If the Sts_OL bit is high, the application will
increment straight to the Conveyor Sync Stop rung (Step 50) - otherwise, it
will move to the Tracked Motions (Step 40)
(Fig. 6-20).
