produce a plc logic ladder diagram
2) Automate the Process - Modify the existing logic in R01_MainControl so, a) Instead of PBA, use an ON delay timer to automatically extend the Divert cylinder after LTA has been on for 5 seconds. b) Instead of PBB, use an ON delay timer to automatically raise the Lift after LTB has been on for 1 second. c) Instead of the Part Release Part Present sensor, use an ON delay timer to automatically lower the Lift 0.5 seconds after it has fully raised. 3) Increase Efficiency and Run Multiple Parts - Modify your existing logic in R01_MainControl to, a) Ensure the part is settled at the Part Release, use an ON delay timer to ensure the Part Release Part Present sensor detects a part for 0.5 seconds before turning on the Part Release solenoid. b) Increase how quickly the next part can enter by rewriting the Part Release solenoid logic so that it turns on when a part is settled, LTA is off and the Divert is retracted and then it turns off as soon as the part is clear of the station. Use an OFF delay timer to extend the part sensor signal to ensure the part does not get trapped when the solenoid turns off. xMove the lift being lowered condition to the Divert cylinder extend logic, also consider adding the condition that LTB has to be off as well. 4) Fault Detection a) Add a new Subroutine called R04_Faults. b) Create the following Boolean tags: LiftFault, DivertFault, EstopFault c) Add a 3SR instruction in the Main Routine to jump to the new subroutine. d) In R04, add logic to turn on LiftFault if the lift doesn't raise within 10s. e) In R04, add logic to turn on DivertFault if the divert doesn't retract in 55 . LAB TIP: To test this on your station tighten the flow controls so that the cylinder doesn't work properly. To test this on the Lab Simulator, adjust the extending and retracting times of the cylinder from the start up screen. Don't forget to change it back! f) In R.04, add logic to turn on EstopFault when the Emergency Stop is pressed and keep it on for an additional 5 seconds after the emergency stop is released. 9) In RO4, turn on the red light when any one of the fault tags is active. Optional Challenge: Using one or two timers, modify the logic so the red TP Light flashes on for 1 second, then off for 1 second continuously when a fault is active
