The DeltaV Explorer presents a view of the overall structure and layout of your system. The tree view shows your control strategies and the hierarchy of the nodes on your Control Network. These nodes can be physically connected to the system, or they can be placeholders configured prior to the installation of the actual hardware.
When you check out your system, remember that the DeltaV Explorer gives you a view of your database, but this may not necessarily match what is actually installed on the network. For example, before connecting controllers, you can define them as controller placeholders in the Control Network. The icons for the placeholders appear in the DeltaV Explorer but are not bound to any device. Then, when the controllers are available and connected, you drag and drop them from the Decommissioned Controllers section to the controller placeholder icons in the Control Network.
Resolving system problems is often a matter of making sure the database and the network match and making sure all the nodes on the network have information about all other nodes. The Download commands in the DeltaV Explorer provide the nodes with all the information they need to operate and interact with other nodes.
