METHOD AND APPARATUS FOR SEAMLESS STATE TRANSFER BETWEEN USER INTERFACE DEVICES IN A MOBILE CONTROL ROOM
First Claim
1. A system for operating a process control plant, the system comprising:
- 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;
a first user interface device communicatively coupled via a network to the unitary, logical data storage area and operable to execute one or more first routines, each first routine for performing a control function, an operation function, a configuration function, a maintenance function, a data analysis function, a management function, a quality control function, or a security function; and
a second user interface device communicatively coupled via the network to the unitary, logical data storage area and operable to execute one or more second routines, each second routine corresponding to one of the first routines;
wherein the first user interface device is operable to pass to the second user interface device state information indicative of one or more first routines operating on the first user device such that the second user interface device, upon receiving the state information, executes one or more of the second routines corresponding to one or more of the first routines operating on the first user interface device.

Abstract
Methods and systems for operating a process plant include multiple user interface devices, each operating a plurality of applications, and operable to pass device state from device to device. A first user interface device is communicatively coupled to a unitary, logical data storage area, and executes one or more first routines for performing a function. A second user interface device is communicatively coupled via a network to the unitary, logical data storage area and executes one or more stored routines each corresponding to one of the first routines. The first user interface device passes to the second user interface device state information indicative of one or more first routines operating on the first user interface device such that the second user interface device, upon receiving the state information, executes one or more of the second routines corresponding to one or more of the first routines.

20. A method of operating a process plant, the method comprising:
-
executing, on a first user interface device, one or more first routines for performing a function in the process plant, the one or more first routines operable to access process data; tracking the state of the one or more first routines executing on the first user interface device; storing the state of the one or more first routines executing on the first user interface device; transferring to a second user interface device the stored state of the one or more first routines executing on the first user interface device; executing, on the second user interface device, according to the stored state, one or more second routines corresponding to the one or more first routines; and performing, using the second user interface device, a function in the process plant. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35)
