P3-550E Ethernet Implicit IO to Controllogix Generic Ethernet Module correct settings

I am having issues resolving a Ethernet I/P IO Message to a Controllogix processor. No matter what I tried I am getting an “Invalid Segment in Path” error. I am at a loss as to what it is looking for

    Hello all,

    Thanks for all of the feedback. The issue is that the Allen Bradley controllers cannot be made to work as an ADAPTER. They can only be SCANNERS.. So. By using the P550-E as an ADAPTER I will need to install an Allen Bradley Compactlogix controller to act as a “Pass Though”. That way the Compactlogix “Pass Through” will send data to the P550E using the P550E as an Ethernet/IP adapter. The Compactlogix will gather all of the data from the 8 process skids, move the data into arrays and push them to the P550E.. Not ideal but it will work..

    1.) Confirming you are using the P3 as the Scanner and the ControlLogix as the adapter?

    2.) Can you provide screenshots of your P3 T->O, O->T & Config tab settings?

    3.) Do you have an EDS file you imported into P3?

    4.) Provide screenshots of your AB Enet/IP config screens.

    P3-550E is the Scanner AB Controllogix is the Adapter using GENERIC ETHERNET MODULE

    I there an EDS file for a 1756-ENBT that would import? Or I am looking for the GENERIC ETHERNET MODULE EDS?

    Also, 1756-ENBT/A. Is in Slot 11. 1756-L63 is in Slot 0.. Tried Routing to slot 0… nothing.

    Based on the images you have provided, you are currently setting up both the ControlLogix CPU and the P-Series CPU as Scanners (client devices). As you have encountered, this is not going to work.

    To get these two devices communicating quickly...

     

    SCANNER

    I would configure ControlLogix as the Scanner, using the ETHERNET-MODULE Generic Ethernet Module that you are currently using, and apply the following parameters:

     

    • Input Assembly Instance: 101
    • Input Assembly Size: 10 (16-bit elements)

     

    • Output Assembly Instance: 102
    • Output Assembly Size: 10 (16-bit elements)

     

    • Configuration Assembly Instance: 1
    • Configuration Assembly Size: 0

     

    ADAPTER

    I would configure the P-Series CPU as the Adapter, using the EtherNet/IP Adapter window in the Productivity Suite, using the information provided in the image.

     

    P-Series_AdapterSetup 

    I hope this gets you moving forward in you project.

    Thanks for the response. I would like to make the P3-550E as the Adapter but I will need another 8 Controllogix processors to connect to the P3-550E. The AD processor is being used as a bulk material distribution center that has to receive requests from a total of 9 process skids. What would be the best approach? Thanks in advance.

      If the P-Series CPU is configured as an EtherNet/IP Adapter...

      • Up to 4 separate data blocks can be configured for the T->O data, with up to 500 bytes per block.
      • Up to 4 separate data blocks can be configured for the O->T data, with up to 500 bytes per block.
      • Multiple connections can be made to any T->O data block using an Input Only or Listen Only connections. More information on that is available in the software help topic P257.
      • Only ONE Exclusive Owner connection per O->T data block can be established at one time. In other words, only one scanner can control a given Output Data block.
      • T->O data intended for multiple consumers can be packed into a single large data block, or distributed across the other T->O data blocks.

       

      This data itself can easily be shared with multiple devices. The 'work' is always in the how you parse and distribute the data.

       

      Hopefully, this information triggers several ideas and possible approaches for you.
