Since the configuration and management data is mapped into the IFS, the IFS well
supports access from configuration and management tools from outside the network.
Figure . depicts an architecture with configuration and management tools that access
the IFS of a fieldbus network from the Internet.
The IFS maps different data domains like RS data, configuration data, and management data using
a consistent addressing scheme. In fact, the management interface can be used to define the RS data
set dynamically (e.g., to select between a smoothed measurement and a measurement with better
dynamics as the output from a sensor). While it is required to provide real-time guarantees for com-
munication of real-time data, the access to configuration and management data is not time critical.
This enables the employment of Web-based tools for remote maintenance.
