Setting up DeviceNet on the Drive

EDS Files Assemblies
  • What assemblies are you working with?
  • Drive should be setup for proper assemblies to match PLC
    • Assemblies must be configured using SoMove or in the remote HMI.  
    • Compatible assemblies with the Process Drive are listed below:
      • Communication Scanner Assemblies (Default)
        • 21 and 71 is the default assemblies if you want to change them through the keypad go thru the Main menu: Choose communications enter, then Devicenet enter, Choose conf. Assmebly Now choose and change the assemblies to 100/101
          • (Input and Output Com Scanner Assemblies) (Set up your input and output Scanner tables on the HMI)
          • From the HMI or keypad display Go to main menu: choose communications enter,  Then Communication parameters enter, Modbus SL enter, Modbus Fieldbus enter, scroll down to the bottom of the screen and you will find the Com Scanner Input and Output table.
          • Works with IO Profile.
      • ​Other Drive Assemblies
        • 20: Basic speed control output
        • 21: Extended speed control output
        • 70: Basic speed control input
        • 71: Extended speed control input
          • When using these assemblies you must follow Case 1 or 2  see below the instructions to follow.

        • 103 and 104 - Allen Bradley Assemblies are not available on the Process Drive.
