1. A schematic generator for use with a process control network having a plurality of devices that communicate over a bus, wherein each of the devices is capable of performing a process control function and stores linkage data pertaining to the manner in which the devices are configured to operate within the process control network, the schematic generator comprising:

  • a device interrogator that interrogates each of the devices over the bus to retrieve the linkage data stored in each of the devices;

    a data analyzer that analyses the retrieved linkage data to determine current process control configuration information; and

    a generator that creates a graphical schematic illustrating a current process control configuration of the process control network using the current process control configuration information.
