1 Job Sheet 4 PLC-Controlled Conveyor nd Sensors OBJECTIVE To fmilirize yourself with the vrious sensors provided with the Flexible Mnufcturing System nd mesure their respective sensing rnges. To use the Flt Belt Conveyor to drive box from the Pneumtic Box Feeder to the sensor instlled in the middle of the conveyor. PROCEDURE 1. Perform the bsic sfety procedures listed in Appendix F of this mnul. 2. Mke sure the system is configured for Ethernet communiction s described in the Ethernet configurtion procedure given in Job Sheet Mke sure the DeviceNet network is configured ccording to the procedure described in Job Sheet 3. Use the sved DeviceNet configurtion file (Networx_1st_Config) to speed up the DeviceNet configurtion. 4. Use Tble 4-1 nd Figure 4-17 to identify the components tht will be dded to the setup used in this Job Sheet. Tble 4-1.

Whether using compressed ir from compressed ir supply locted in the clssroom or from n ir compressor, mke sure to djust the pressure in the circuit downstrem from the vlve of the Conditioning Unit to 138 kp (or 20 psi). The pneumtic cylinder instlled on the Pneumtic Box Feeder is equipped with two needle vlves llowing control of the ir flow. Use these vlves to djust the speed t which the Pneumtic Box Feeder rects when ctivted. 9. Connect the equipment s shown in the wiring digrm presented in Figure Festo Didctic

8 Blnking Plugs Figure PLC-controlled conveyor nd sensors setup. Running the progrm Mke sure RSLinx nd RSNetWorx for DeviceNet re running on your computer before trying to downlod the progrm to the PLC. 12. Before downloding the progrm to the PLC, restore the RSNetWorx configurtion mde in Job Sheet 3. To do so, strt RSNetWorx for DeviceNet (if not lredy strted). 13. From the File menu, select Open nd open the file nmed Networx_1st_Config (Refer to Job Sheet 3 for detils). 14. Opening the Networx_1st_Config file restores the DeviceNet configurtion mde in Job Sheet Festo Didctic

15. Open the RSLogix 5000 project file nmed intro_mnu_stu4.cd nd downlod the progrm to the PLC. Refer to the Running the progrms procedure given in Job Sheet 2 for detils on downloding progrms. 16.

Mke sure the setup is working properly. You should be ble to: strt the Flt Belt Conveyor (clockwise rottion) using the green push button on the Indictor Light/Push-Button Sttion; stop the Flt Belt Conveyor using the red push button on the Indictor Light/Push-Button Sttion (pressing the green push button resumes the mnufcturing process simultion); cut off the power in cse of emergency with the Emergency Switch Sttion; drop nother box using the yellow push button on the Indictor Light/Push-Button Sttion; observe tht the red indictor light turns on when the AC Drive is redy nd turns off when the Flt Belt Conveyor is rotting; observe tht the green indictor light turns on when the Flt Belt Conveyor is rotting clockwise; observe tht once the Flt Belt Conveyor is rotting, box is dropped by the Pneumtic Box Feeder; Reset the system using the red push button on the Indictor Light/Push- Button Sttion; observe tht the Flt Belt Conveyor stops if box is detected by the Inductive Proximity Switch. A video of the setup presented in this Job Sheet is vilble on the Flexible Mnufcturing System Resource Kit (student) CD-ROM. 17. Once you re sure the setup is working properly, press on the green button to strt the Flt Belt Conveyor. 18. Use the AC Drive potentiometer to djust the AC Drive output frequency (i.e. the conveyor speed) to 10 Hz. 19. Drop box on the Flt Belt Conveyor using the yellow push button. The conveyor should stop before the box reches the sensor. Festo Didctic

10 20. Mesure the distnce between the ctive fce of the Inductive Proximity Switch nd the side of the box when the conveyor stops. This is the sensing distnce of the Inductive Proximity Switch for this setup. Write down the sensing distnce of the Inductive Proximity Switch below: Inductive Proximity Switch sensing distnce 21. Replce the Inductive Proximity Switch with the Bckground Suppression Photoelectric Switch. Use the sme wiring s for the Inductive Proximity Switch. 22. Proceed s for the Inductive Proximity Switch nd write down the sensing distnce of the Bckground Suppression Photoelectric Switch below: Bckground Suppression Photoelectric Switch sensing distnce 23. Ask the instructor to check nd pprove your work. Troubleshooting exercise Prior to this exercise, the instructor must insert fult into the circuit of the Flexible Mnufcturing System. 24. Try to use the setup nd determine whether everything is working properly. 25. If the system is not working properly, describe the symptom(s). 26. Use your troubleshooting skills to identify the mlfunctioning module(s) nd isolte the problem(s). 96 Festo Didctic

11 27. Explin in detil your pproch to isolting the problem. 28. Ask the instructor to check nd pprove the Troubleshooting Exercise. Progrmming exercise Mke sure there is no fult from the troubleshooting exercise left on the setup. In this Job Sheet, box is dropped on the conveyor by pressing the yellow button. The conveyor stops when the sensor detects the box. Modify the progrm so tht the yellow light turns on if the opertion described bove is performed five times in row. 29. Once this exercise is complete, sk the instructor to check nd pprove your work. Nme: Dte: Instructor's pprovl: Festo Didctic
