Methods and systems for operating a process plant include multiple user interface (UI) devices, each accessing a plurality of applications on a server, and operable to store device state on the server and receive device state from the server. The server is coupled to a unitary, logical data storage area and provides functions related to the process data stored in the data storage areas via one or more user interfaces. A first UI device coupled to the server accesses the process data and maintains on the server state information indicative of a state of the user interface executing on the first UI device. A second UI device coupled to the server accesses the process data and the state information to execute a user interface on the second UI device in accordance with the state information indicative of the state of the user interface executing on the first UI device.
