Set up a redundant DeltaV Control Network

A redundant DeltaV Control Network uses primary and secondary communication cables between controllers and workstations.

  1. Make and test the control network cables.
  2. Connect the unshielded end of a network cable to the twisted pair port on the workstation's primary Network Interface Card (NIC).
  3. Connect the shielded end of the network cable to the primary switch
  4. Connect the unshielded end of a network cable to the twisted pair port on the workstation's secondary Network Interface Card (NIC).
  5. Connect the shielded end of the network cable to the secondary switch.
    It is helpful to identify the control network cables with color-coded boots. Emerson recommends a yellow boot for the primary control network and a black boot for the secondary control network.


  6. Connect the network cables from the switches to the control network connectors on the bottom of the controller. Use shielded connectors at the controller. The front connector is for the primary control network and the rear connector is for the secondary control network.
