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.

Claims

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;

retrieve process data for display on a first user interface device;

transmit to the first user interface device the retrieved process data;

store state information associated with the display of the process data on the first user interface device;

retrieve process data for display on a second user interface device according to the stored state information; and

transmit to the second user interface device the process data retrieved according to the stored state information.

2. A server according to claim 1, wherein transmitting retrieved process data to the first user interface device comprises transmitting to the first user interface device process data viewable in a web browser executing on the first user interface device.

3. A server according to claim 1, further comprising formatting process data for display on a first user interface device according to a device type of the first user interface device.

4. A server according to claim 1, further comprising formatting process data for display on a second user interface device according to the stored state information and according to a device type of the second user interface device.

5. A server according to claim 4, wherein formatting process data for display on a second user interface device according to the stored state information further comprises formatting process data for display on a second user interface device such that an operational state of the first user interface device is duplicated on the second user interface device.

6. A server according to claim 5, wherein transmitting formatted process data to the first user interface device comprises transmitting to the first user interface device process data viewable in a multi-purpose process control application executing on the first user interface device.

7. A server according to claim 1, wherein the first user interface device is of a different type than the second user interface device.

8. A server according to claim 1, wherein the first user interface device is a workstation and the second user interface device is a mobile device.

9. A server according to claim 1, wherein the first user interface device is a first mobile device and the second user interface device is a second mobile device.

10. A server according to claim 1, the machine-readable instructions further comprising instructions executable by the processor to receive a request from the first user interface device to provide to the second user interface device a user interface according to the stored state information.

11. A server according to claim 1, the machine readable instructions further comprising instructions executable by the processor to establish with the second user interface device, in response to the request to provide a user interface according to the stored state information, a secure communication channel between the server and the second user interface device.

12. A server according to claim 1, the machine-readable instructions further comprising instructions executable by the processor to receive a request from the second user interface device to provide to the second user interface device a user interface according to the stored state information.

13. A server according to claim 1, wherein the stored state information includes one or more of:

(a) a display configuration of the first user interface device;

(b) a portion of the process plant displayed by the first user interface device;

(c) data of a process control device displayed by the first user interface device;

(d) a function being performed on the first user interface device, the function including one or more of 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

(e) a user profile active on the first user interface device.

14. A method performed by a server facilitating mobile control of a process plant, the method comprising:

transmitting to the first user interface device the retrieved process data;

storing state information associated with the display of the process data on the first user interface device;

retrieving process data for display on a second user interface device according to the stored state information; and

transmitting to the second user interface device the process data retrieved according to the stored state information.

15. A method according to claim 14, wherein transmitting retrieved process data to the first user interface device comprises transmitting to the first user interface device process data viewable in a web browser executing on the first user interface device.

16. A method according to claim 14, further comprising formatting process data for display on a first user interface device according to a device type of the first user interface device.

17. A method according to claim 16, wherein formatting process data for display on a second user interface device according to the stored state information further comprises formatting process data for display on a second user interface device such that an operational state of the first user interface device is duplicated on the second user interface device.

18. A method according to claim 17, wherein transmitting formatted process data to the first user interface device comprises transmitting to the first user interface device process data viewable in a multi-purpose process control application executing on the first user interface device.

19. A method according to claim 14, further comprising formatting process data for display on a second user interface device according to the stored state information and according to a device type of the second user interface device.

20. A method according to claim 14, wherein the first user interface device is of a different type than the second user interface device.
