  1. MLC Connectivity to SLC 500 via DeviceNet

  2. Equipment Needed for Connecting • MLC 9000 BCM • Allen-Bradley SLC 500 CPU 5/02 or higher • 5/02 smallest CPU to support M0/M1 File Transfer • Allen-Bradley 1747-SDN DeviceNet Scanner • Allen-Bradley RSNetworx or DeviceNet Manager Software • RSLogix PLC Programming Software • PC Interface(i.e 1770-KFD for programming) • DeviceNet Cabling • Thick Trunk Cable with Mini-Connectors • Thin Drop Cable with Micro or Mini-Connectors • T-Connectors • Terminating connectors(110 Ohms)

  3. How SLC500 Communicates with 1747-SDN • Two methods used • I/O Transfer • 1747 occupies 32 Input Words and 32 Output Words • 1 word of input, 1 word of output used for module status and command • 62 words available for devices • Intended for devices transmitting small blocks of information • Proximity and Photoelectric Switches • “Slice” I/O • Valves

  4. How SLC 500 Communicates with 1747-SDN • Block Transfer via M0/M1 Files • M1 File • 150 Words Available for Input from Network Devices (M1:1.0-M1:1.149) • 74 Diagnostic Words (M1:1.150-M1:1.223) • 32 Words for Inbound Explicit Message Control (M1:1.224-M1:1.255)

  5. How SLC 500 Communicates to 1747-SDN • Block Transfer via M0/M1 Files • M0 File • 150 Words of data used for output to network devices (M0:1.0-M0:1.149) • 74 Words Reserved/Unused (M0:1.150-M0:1.223) • 32 Words used for outgoing explicit message control (M0:1.224-M0:1.255)

  6. How MLC 9000 Communicates with 1747-SDN • MLC 9000 Gateway • Converts DeviceNet Messages from Scanner into Modbus Messages to Bus Control Module • Uses Polled Messaging for Implicit I/O Connection • One Loop Control Module takes up 16 Bytes of Input and 6 Bytes of Output • Uses Explicit Messaging to gain access to parameters not supported through implicit connection

  7. Implicit I/O Connection Data

  8. Setting Up PC to Communicate via DeviceNet In RSLinx, Select Communications and Configure driver

  9. Setting Up PC to Communicate via DeviceNet Under Available Driver Types, select DeviceNet Drivers and select Add new

  10. Setting Up PC to Communicate via DeviceNet Select 1747-SDNPT

  11. Setting Up PC to Communicate via DeviceNet Select Processor to Connect to and slot where 1747-SDN resides

  12. Setting Up PC to Communicate via DeviceNet 1747-SDNPT-1 should be seen running

  13. Setting Up SLC500 to Pull Information from 1747-SDN Start RSLogix and Select File-New

  14. Setting Up SLC500 to Pull Information from 1747-SDN Select processor from list

  15. Setting Up SLC500 to Pull Information from 1747-SDN From Menu Tree, Select IO Configuration then add 1747-SDN into Slot 1 of Rack

  16. Setting Up SLC500 to Pull Information from 1747-SDN Highlight on Rung in Ladder Window

  17. Setting Up SLC500 to Pull Information from 1747-SDN • Insert one Normally Closed Contact and Two Copy Instructions into Rung 1 • Copy Instructions move data from M0/M1 Files to usable data areas

  18. Setting Up SLC500 to Pull Information from 1747-SDN • Last Rung Energizes Output Run coil and disables in event of error in module • Download to PLC and place in Run Mode

  19. Configuring the DeviceNet Network • To Configure Network, Gateway EDS file must be installed • EDS (Electronic Data Sheet) carries configuration properties for DeviceNet products • Start RSNetworx then select Tools-EDS Wizard

  20. Configuring the DeviceNet Network Select Register EDS File then select Choose File

  21. Configuring the DeviceNet Network • Select A: Drive then select West0456 • Click Open

  22. Configuring the DeviceNet Network Wizard will run test on EDS

  23. Configuring the DeviceNet Network Wizard will prompt you to associate a graphic icon with EDS

  24. Configuring the DeviceNet Network This will finish the EDS Installation

  25. Configuring the DeviceNet Network Select 1747-SDN from Device List

  26. Configuring the DeviceNet Network Insert MLC 9000 Gateway form Device List

  27. Configuring the DeviceNet Network Double Click on 1747-SDN and select Scanlist

  28. Configuring the DeviceNet Network • Click on arrow to add Gateway to 1747-SDN’s scanlist • Select edit I/O parameters

  29. Configuring the DeviceNet Network • Adjust the Polled Rx and Tx parameters to match the number of I/O taken up by LCM’s • 16 bytes of Rx and 6 bytes Tx for every LCM (up to 8 LCM’s)

  30. Configuring the DeviceNet Network • Select Input • Select Memory Type M file • Select AutoMap

  31. Configuring the DeviceNet Network • Select Output • Select Memory Type M file • Select AutoMap

  32. Configuring the DeviceNet Network • From Main Screen, select Tools then Node Commissioning • Nodes must be commissioned with proper baud rate and node address before the configuration can be downloaded to network • Select Browse

  33. Configuring the DeviceNet Network • Select 1747-SDNPT from list of drivers • RSNetworx will detect connected devices • Select Node to adjust

  34. Configuring the DeviceNet Network Change Node Address and click Apply if changes are needed

  35. Configuring the DeviceNet Network • To prepare for download, network connection must be established online first • Click Network, then Online

  36. Configuring the DeviceNet Network After Online connection established, select network-download to network to send configuration
