GSN Domains

Move an LSNB to a different GSN domain

Effects of moving

Moving an LSNB to a different Global Safety Network (GSN) domain does not change any of the LSNB's properties other than the domain name.
CAUTION!

If you move the last LSNB out of a domain, that domain will be removed from the hierarchy.

You cannot move an LSNB if it is commissioned and/or assigned.

Moving an LSNB to a different domain will affect the publishing of secure parameters. What happens may differ, depending on what is moved:

Scenario 1: Move an LSNB that has publishers, AND move all the nodes which reference the secure parameters it publishes, to the same new domain: no changes to publishers.

Scenario 2: Move an LSNB that has publishers, without moving the referencing nodes:
  • If the LSNB has system publishers, they remain unchanged.
  • If the LSNB has domain publishers, the system automatically converts them to system publishers IF it can.
  • The system will support a maximum of 8 system publishers. If the system already has 5 system publishers, and the LSNB that was moved has 5 domain publishers, only 3 of those will be converted to system publishers. Two domain publishers will remain unchanged.
  • If the unconverted domain publishers hold data that is needed by nodes in the original domain, that data will now be unavailable to those nodes. The preferred option to provide those nodes the data they need is to move the referencing nodes to the new domain, but new instances.
    Note

    It may or may not be possible to create new instances of the secure parameters within the original domain, because the parameters may be associated with specific hardware.

There are two ways to move an LSNB:

Drag and drop

  1. In the DeltaV Explorer hierarchy, expand the view of the Global Safety Network.
  2. Expand the domain holding the LSNB that you will move.
  3. If necessary, decommission and unassign the LSNB.
  4. Click and hold on the LSNB, and drag it onto the name of a different domain.
  5. Assign and commission the LSNB in the new domain.
  6. If necessary, move referencing nodes or recreate secure parameter references so all nodes can still access required secure parameter data.

Use the Properties dialog

  1. In the DeltaV Explorer hierarchy, expand the view of the GSN and find the LSNB that you will move.
  2. If necessary, decommission and unassign the LSNB.
  3. Right-click on the LSNB, and select Properties from the context menu.
  4. In the Domain field, select or enter the name of the GSN domain where you will move the LSNB.
    If the domain you enter does not yet exist, you are prompted to confirm you want to create a new domain.
  5. Click OK.
  6. Assign and commission the LSNB in the new domain.
  7. If necessary, move referencing nodes or recreate secure parameter references so all nodes can still access required secure parameter data.
