6. Overview: Desires 6

7. Solution: Ideal 7 HMI Visual Basic GUI with Modbus Communication Advantages Touchscreen Possibly all Lenze product No need for PLC More direct communication Use of Modbus reduces complexity Visual Basic is supported Disadvantages The use of the HMI adds complexity

8. Solution: Alternative 8 Computer GUI with DAQ and Analog/Digital Communication Advantages No need for Ethernet Switch Can use standard drive A/D ports Computer supports wide variety of GUI options External current sensing feasible DAQ Disadvantages More hardware is needed Less Lenze components and no HMI

9. Other Feasible Solutions 9 Computer GUI with PLC Control and Analog/Digital Communication Advantages No need for Ethernet Switch Can use standard drive A/D ports Computer supports wide variety of GUI options Disadvantages May need external signal conditioning components PLC needs more A/D inputs and outputs making it more costly

10. Other Feasible Solutions 10 Advantages Computer supports wide variety of GUI options Use of Modbus protocol throughout the design reduces design complexity Computer GUI with PLC Control and Modbus Communication Disadvantages Communication rate between the computer and drives is slower

11. Other Feasible Solutions 11 Advantages Computer supports wide variety of GUI options No need for PLC More direct communication Modbus reduces complexity Computer GUI with Modbus Communication Disadvantages More extensive communication programming on the computer

12. Other Feasible Solutions 12 Advantages Touchscreen Possibly all Lenze product Use of Modbus reduces complexity HMI GUI with PLC Control and Modbus Communication Disadvantages HMI does not support as may GUI options Communication rate between the HMI and drives is slower

13. GUI Programs 13 4/9/2014 Copyright © 2014 – Advanced Power Electronics & Electric Drives Lab (APEDL)

14. Visual Basic Pros Visual Basic 6.0 is free to download. Capable of object oriented programming. Free MODBUS toolkit. Links directly to MS Excel: beneficial for creating nice looking graphs. Can run on Windows CE. Lenze team can continue software support for free 14

15. Visual Basic Cons CANopen communication is not well supported. Our team does not have experience with this program. No longer supported by Microsoft 15

16. LabVIEW Pros Well supported by NI Free MODBUS library Our team has experience with this program. Possibility of HMI support NI DAQs are very easy to implement 16

17. LabVIEW Cons CANopen library cost $162 LabVIEW is no longer supported for Windows CE. Lenze team would need to purchase LabVIEW licenses to continue support of the program 17

18. LabVIEW GUI: Basic Tests 18

21. LabVIEW GUI: Periodic Tests 21

22. LabVIEW GUI: Periodic Tests 22

23. LabVIEW GUI: Periodic Tests 23

24. LabVIEW GUI: Real Time Tests 24

25. HMI Lenze HMIs are p500 and p300 Operating system is Windows CE Equipped for MODBUS communication Designed for PLC control. Potentially could control the drives directly from GUI program 25

26. PLC The PLC is a well supported control for the drives and can communicate with the Lenze HMI. Possibly redundant, and unneeded. Adds complexity, but may prove necessary if MODBUS or CAN does not work. 26

27. MODBUS Modbus only requires Ethernet ports Supported by free libraries. Well documented Lower communication rate. Dependent on Ethernet cable 27

28. CANopen Faster communication rate Requires a CANopen reader card or dongle Libraries cost money Less supported than MODBUS in most cases 28

29. Analog/Digital Requires the use of a data acquisition module (DAQ) Fast communication Will integrate well with additional external sensors such as per phase current sensors. Requires less software development 29
