A manufacturing/process control system information access provider
architecture is disclosed. Manufacturing/process control system data
provider flexibility is achieved through a user-configurable
manufacturing/process control information portal server that comprises
multiple selectable data provides (sources) and/or data types that a
particular data provider accommodates. A user configures the portal
server to deliver manufacturing/process control information associated
with a controlled process environment, such as a food processing plant
floor or an oil refinery reactor, to the user via a browser client over
the Internet or a corporate intranet. Furthermore, an extensible
architecture is provided that enables adding new components to the portal
server. Such extensions include new data sources and new data
types/handlers. The new architecture enables a user to select particular
ones of the available data handlers and then their associated data
sources thereby facilitating customizing the configuration of the portal
server to the particular needs/interests of the user.
