Abstract
A networked control system includes graphical representations of actual devices coupled to a network. The graphical representations include symbols that provide an actual picture of the devices and means for displaying values and status of the devices. A controller uses a system database to create an application database that is used for controlling and monitoring the devices. The system database includes templates for the physical devices with a control structure that has prelinked parameters that relate to the representation. A graphic editor allows a user to create the database from templates in the system database. Data and other device parameters are automatically linked to a device symbol when creating the graphical representations. A process controller couples the devices to the network and provides the data and status of the networked device to the system database.
