Nodes are physical devices or pieces of equipment on the LAN, such as a controller or a workstation. You control your process by downloading modules and defining I/O blocks and other configuration elements in the nodes. The configuration tells the node how to act and what information you want to receive or save from the process.
You can define a node using the Configuration Assistant application or the DeltaV Explorer. To look at the status of a node, use the Diagnostics application.
