Method and apparatus for seamless state transfer between user interface devices in a mobile control room
First Claim
1. A server for facilitating mobile control of a process plant, the server comprising:
- a processor communicatively coupled via a network to a unitary, logical data storage area including one or more data storage devices configured to store, using a common format, process data corresponding to the process plant, the process data including multiple types of process data selected from configuration data, measurement data, batch data, continuous data, and event data; and
a memory device communicatively coupled to the processor and storing machine-readable instructions, executable by the processor to cause the processor to;
receive a first set of process data corresponding to process parameters in the process plant for display on a first user interface device having a processor and a memory device, the first set of process data including configuration data, measurement data, batch data, continuous data, and/or event data, wherein the first user interface device is configured to perform a function in the process plant;
transmit to the first user interface device the received first set of process data;
obtain a session identifier for a session created on the display of the first user interface device;
store the session identifier with state information generated during the session, wherein the state information is associated with the display on the first user interface device and includes a state of a graphic representation related to at least one of the process parameters corresponding to the first set of process data;
receive, from a second user interface device, a request for state information for the session created on the display of the first user interface device;
receive a second set of process data corresponding to the process parameters for display on the second user interface device according to the stored session identifier and state information, wherein the second user interface device includes another processor and another memory device; and
transmit to the second user interface device the second set of process data received according to the stored session identifier and state information, wherein the second user interface device is configured to perform a function in the process plant.

Abstract
Methods and apparatus for operating a process plant include a server providing display information to a first user interface (UI) device, storing state information, and providing display information to a second user interface device according to the stored state data. A processor is coupled to a unitary, logical data storage area and to a memory device that stores machine-readable instructions executable by the processor. The instructions cause the processor to retrieve process data for display on a first UI device, transmit to the first UI device the retrieved process data, store state information associated with the display of the process data on the first UI device, retrieve process data for display on a second UI device according to the stored state information, and transmit to the second UI device the process data retrieved according to the stored state information.
