Install the Control Network Cables

  1. Make and test the required Control Network cables. See the section, "Control Network Specifications" for cable guidelines and specifications. Select the appropriate cable type on the cable test tool and follow the detailed instructions in the test tool’s manual.
    You must connect the test equipment to both ends of the cable to test it properly. The testing tool checks each cable based on its type and issues a Pass or Fail reading. Make sure the cable passes each test. The tests supported by the Microtest PentaScanner testing tool include the following:
    • Cable mapping
    • Length
    • Crosstalk
    • Attenuation
    • Attenuation-to-crosstalk ratio
    • Impedance
    • Loop resistance
    • Capacitance
    CAUTION!

    Substandard cables can create serious communication problems. Make sure all cables meet the specifications listed in the "Control Network Specifications" section.

  2. If you have a simplex Control Network, connect the unshielded end of a network cable to the twisted pair port on the primary Network Interface Card (NIC) and connect the shielded end of the cable to the primary switch as shown in the following figure.
    Figure: Simplex Control Network Cable Connections


    For redundant Control Networks, be sure to verify the NIC binding order to differentiate between the primary and secondary NICs.

  3. If you have a redundant Control Network, connect the unshielded end of a network cable to the twisted pair port on the workstation’s primary NIC and connect the shielded end of the cable to the primary switch as shown in Figure: Redundant Control Network Cable Connections. Connect another cable from the twisted pair port on the workstation’s secondary NIC to the secondary switch. It is helpful to identify the Control Network cables with color-coded boots. Emerson recommends the following conventions: a yellow color-coded boot for the primary Control Network cable and a black color-coded boot for the secondary Control Network cable.
    Note

    Make sure you are consistent in your primary and secondary network connections so they are not crosswired.

  4. Connect network cables from the switches to the RJ45 connectors on the front of the carrier. The left side ports are the primary ports and the right side are the secondary ports (for use with redundant networks). The ports must be enabled on the controller's Properties page in DeltaV Explorer.
