Abstract
A system for displaying statistical data in a process control environment. A client device connects, via a network, to a historian connection module, and subscribes, via the connection to the historian connection module, to statistical data stored in a historian server module. A historian device receives a connection, by the historian connection module via the network, from the client device, forms a connection between the historian connection module and the historian server module, receives a subscription, by the historian connection module via the network, to statistical data stored in the historian server module from the client device, and stores, by the historian connection module, the received subscription.
