Hi, i have 2 question regarding the attached simulation: first, operator need to finish the process in order (operation OP10,OP20 and OP30), i already change the preempt only (priority 1) for OP30, but still the operator go back from OP20 to OP10 and not finish OP30. Second i add a process time of 5 seconds in OP10, but the combiner finish up to 42.26 sec. Not sure how to finish exactly in 5 sec all 5 items from combiner. ThanksCombiner, operator process order.fsm
