The DeltaV Wireless I/O Network > DeltaV Wireless Gateway

Commission Wireless Gateway nodes

When the system is powered up, any Wireless Gateway nodes that are physically connected are listed under Decommissioned Nodes in DeltaV Explorer. To commission a Wireless Gateway node, you can drag-and-drop a decommissioned Wireless Gateway to the Wireless I/O Network or to a placeholder under the network that you configured in advance. It is recommended that you commission one Gateway at a time as it is difficult to distinguish one Gateway from another when commissioning multiple Gateways simultaneously. When you commission a Wireless Gateway, you are prompted to autosense it. If you choose to autosense the Gateway, the wireless Reconcile I/O dialog opens. During the commissioning process, a red X can temporarily appear on the Wireless Gateway node until the commissioning process completes.

If you notice a loss of communication with a Wireless Gateway after commissioning it (a red X persists on the Wireless Gateway node in the DeltaV Explorer and DeltaV Diagnostics hierarchies), it is possible that some security protocols have not been enabled. Follow these steps to enable the protocols.

  1. Select the Wireless Gateway under the Wireless I/O Network in DeltaV Explorer and use the context menu commands to log onto the Wireless Gateway's web interface using the admin account (user=admin). Refer to the Quick Installation Guide that ships with the 1420 for the default password.
  2. Navigate to Setup/Security/Protocols and enable the DeltaV Commissioner and HART UDP Port protocols.

    If these items are already enabled, exit the web interface and use DeltaV Diagnostics along with the troubleshooting information provided in the Wireless Gateway documentation to troubleshoot the communication problems.

  3. After enabling the DeltaV Commissioner and HART UDP Port protocols, exit the web interface, and decommission the Wireless Gateway.
  4. Open DeltaV Diagnostics, navigate to the Wireless Gateway node under Decommissioned Nodes, and use the context menu commands to log onto the Wireless Gateway's web interface using the admin account.
  5. Navigate to Setup/Security/User Accounts, select the Enable factory support accounts option, and click the Submit button. Click OK on the dialog that appears.
  6. Click the Restart Apps button, click Yes in response to the prompts to restart the application software, wait for the restart to complete, and close the web interface.
  7. From DeltaV Diagnostics, log onto the Gateway's web interface using the factory account (user=factory) and click Cancel on the dialog that appears.
  8. Navigate to Setup/Security/Protocols in the Wireless Gateway's web interface and confirm that the DeltaV Commissioner and HART UDP Port protocols are enabled.
  9. Navigate to Setup/Factory Settings, select the Save the settings as factory defaults option, and click the Submit button.
  10. Click the Restart Apps button.
  11. Click Yes to the Restart the application software now prompt and wait for the restart to complete.
  12. Close the web interface when the restart is complete.
Note

It is expected that decommissioning a functional Wireless Gateway node would be a rare occurrence. However, if you should decommission a functional Wireless Gateway node with a redundant network in DeltaV Explorer, first open DeltaV Diagnostics and check the status of the node's Primary and Secondary communication links. Be sure that at least one of the communication links is Good. The Wireless Gateway node does not lose its IP address when both communication links are Bad and will not appear under the Decommissioned nodes list in DeltaV Explorer. For firmware version 3.xx, the only way to recommission the Wireless Gateway node when both communication links are Bad is to open the Gateway's housing, install a jumper to restore the factory settings, and then commission the Gateway. For firmware version 4.0 and higher, the only way to recommission the Wireless Gate node when both communication links are Bad is to open the Gateway's housing, move DIP switch 2 on the center circuit board to the ON position (left) to restore the factory settings and then commission the Gateway. For a simplex network, be sure that the Primary communication link is Good. Refer to the device documentation for information on how to restore the factory settings.

Tip

After you decommission a Wireless Gateway node, a routine delay is normal before it appears in the list of Decommissioned Nodes in DeltaV Explorer. Also, you may need to wait for up to five minutes before recommissioning a recently decommissioned Wireless Gateway node or decommissioning a recently commissioned Wireless Gateway node.
