Add carriers to an operational system

Additional carriers and components can be added to an operational DeltaV SIS system to extend the system. However, care must be taken to add the carriers without disrupting communication on the local peer bus. Follow these steps to add one or more 8-wide carriers to an operational system.

WARNING!

Be sure to follow the manufacturer's installation procedure and all applicable plant procedures when performing installation maintenance on an operational system. Failure to follow the appropriate procedures could result in unexpected and undesired system operation.

  1. Install a left and right one-wide carrier to the 8-wide carrier that you intend to add to the existing system.
  2. Connect the 44 pin D-Shell carrier extender cables between the existing carrier and the new carrier.
  3. Remove the 120 ohms BNC terminator from the secondary black connector on the existing right one-wide carrier and install it on the black connector on the new right one-wide carrier.
  4. Connect the local peer bus cable from the open, secondary black BNC connector on the existing carrier to the secondary black BNC connector on the new left one-wide carrier.
  5. Open DeltaV Diagnostics and verify that there are no MaintAlerts or AdviseAlerts involving SISNet Error or SISNet High Error Rate for any Logic Solver. Also if using SISNet Repeaters, verify that Repeater02 OInteg is Good.
    WARNING!

    Do not proceed until all alerts and statuses are Good in DeltaV Diagnostics.

  6. Remove the 120 ohms BNC terminator from the primary white connector on the existing one-wide carrier and install it on the white connector on the new right one-wide carrier.
  7. Connect the local peer bus cable from the primary white BNC connector on the existing right one-wide to the primary white BNC connector on the new left one- wide carrier.
  8. In DeltaV Diagnostics verify that there are no MaintAlerts or AdviseAlerts involving SISNet Error or SISNet High Error Rate for any Logic Solver. If using SISNet Repeaters, verify that Repeater01 OInteg is Good.
