3. Ethernet-based market share
Reported in 2009
Ethernet encompasses several protocols, with increasing adoption rates among manufacturers
Standard ensure consistent interface with products from various vendors
North America has a heavy focus on EtherNet/IP = Rockwell Automation
Profinet = Siemens
ModbusTCP/IP great de facto protocol
EtherCAT limited market share

4. Ethernet-based market share
Reported in 2013
77% of Ethernet protocols supported by Lexium MDrive
EtherNet/IP still strong
EtherCAT slow growth
Market / opportunity drive decisions for growth

6. EtherNet/IP EtherNet/IP is the most commonly used Ethernet protocol
MDrive Ethernet products operate as slave/adapter class devices over EtherNet/IP
Network standards allow interface among products from various vendors, including:
Rockwell Automation Omron Rexroth Schneider Electric

7. EtherNet/IP conformity
EtherNet/IP standardization is administered by ODVA to ensure Common Industrial Protocol / CIP™ conformance
All MDrive Ethernet products are ODVA certified
ODVA-certified products ensure conformance to the EtherNet/IP CIP standard

8. EtherNet/IP MDrive & Rockwell
MDrive/Rockwell PLC interface
Rockwell PLC lists MDrive as CIP Generic Device
MDrive “talking”
EtherNet/IP MDrive & Rockwell
Rockwell Automation
> North America focus > Growing worldwide Rockwell products / messaging type
> CompactLogix – implicit and explicit > ControlLogix – implicit and explicit > MicroLogix (select version) – explicit
MDrive products / messaging type
> Lexium MDrive – implicit(1) and explicit > MDrive Plus 23 – implicit(1) and explicit (1) I/O data

9. EtherNet/IP MDrive/Rockwell PLC interface
IP and EIP configuration of MDrive • Terminal communication to MDrive • Export of user defined data types to PLC
Import of user defined data types to PLC

10. EtherNet/IP MDrive/Rockwell PLC interface
Sample implicit message blocks
Sample explicit message block

11. EtherNet/IP application example
Commercial electronic device tester
27 sets of three-axis “Pick and Place” assemblies controlled by Lexium MDrive and MDrive Plus
All 81 axes networked over EtherNet/IP back to Rockwell ControlLogix PLC
PLC coordinates homing, all move profile information, and target positions

12. EtherNet/IP application example
Material handling
Conveyor assembly manipulates packages
Up to 16 axes of Lexium MDrive controlled by Rockwell ControlLogix PLC
PLC continually updates motor velocity command to change direction of package for scanning

13. Modbus TCP/IP
Availability of devices using Modbus TCP/IP has made it a de facto standard for industrial communication networks
PLC, Motion Control, and HMI manufacturer’s heavily supported
ABB, Automation Direct, Schneider Electric, Galil, Trio, Proface, Red Lion, Maple, Kinco, SAIA, etc.
Implemented in all Ethernet-based Lexium MDrive products, as well as MDrivePlus products

14. Modbus TCP/IP
Lexium MDrive parameters are considered “holding” registers, denoted by 4x address base
Local program can run while being networked

15. Modbus TCP/IP application example
Material handling
Auger control for dispensing
HMI data entry for motor velocity and distance
Variable then sent to start motion subroutine stored in NVM

16. Modbus TCP/IP application example
Pump dispensing system
Recipe created in HMI for specific volumetric parameters
Acceleration
Deceleration
Time to dispense
Fill volume
Variable then sent to start motion subroutine stored in NVM, once parameters loaded

17. Profinet Lexium MDrive is “I/O device” on Profinet I/O network
Implements Profibus DP over Ethernet hardware
I/O data Alarms Diagnostics Data records
