Assignee:

Honeywell Inc. - Morristown NJ

International Classification:

G06F 1750

US Classification:

716 3

Abstract:

A system for, and method of, disseminating a functional block to a redundant controller for a real-time process control system and a real-time process control system incorporating the system or the method. In one embodiment, the system includes: (1) a dynamically linkable library object associable with the functional block and (2) a shared memory, associated with at least two nodes of the redundant controller, that receives the dynamically linkable library object and the functional block and provides concurrent access thereto by both the at least two nodes to ensure consistent memory images therefore without requiring one of the at least two nodes to be taken off-line.

International Classification:

H04L 29/06
H04L 9/00

US Classification:

713153, 380270

Abstract:

A method includes synchronizing a first gateway with information from a second gateway. The second gateway operates in a primary role with at least one primary network address. The second gateway communicates with at least one wireless device that uses at least one encryption key during at least one secure communication session. The information includes the at least one encryption key. The method also includes detecting a switchover event at the first gateway. The method further includes, in response to detecting the switchover event, switching the first gateway to the primary role, communicating using the at least one primary network address, and maintaining the at least one secure communication session at the first gateway after the first gateway switches to the primary role.

Appl. No.:

9/049880

Inventors:

Paul Francis McLaughlin - Hatfield PA
Joseph P. Felix - Glenside PA
Norman Raymond Swanson - Doylestown PA

Assignee:

Honeywell International INC - Morristown NJ

International Classification:

G05B 902

US Classification:

700 82

Abstract:

There is disclosed a redundant process controller for use in a process facility having a plurality of process systems that produce process data, wherein the process data are gathered by process controllers associated with the process systems and are exchanged by the process controllers via a network. The redundant process controller is associated with a first selected process system and is capable of receiving process data from at least one remote process controller and intermittently transferring the received process data to the first selected process system. The redundant process controller comprises 1) a primary process controller capable of storing the received process data, wherein the primary process controller transmits the received process data to the first selected process system; and 2) a secondary process controller capable of storing the received process data, wherein the secondary process controller detects failures in the primary process controller and, upon detection of a failure, transmits to the first selected process system the received process data in lieu of the primary process controller.

Appl. No.:

8/993336

Inventors:

Paul Francis McLaughlin - Hatfield PA
Norman Raymond Swanson - Doylestown PA

Assignee:

Honeywell Inc. - Morristown NJ

International Classification:

G06F 1200

US Classification:

711162

Abstract:

There is disclosed a system and method for maintaining data coherency between a primary process controller operable to execute process control tasks and a backup process controller operable to replace the primary process controller upon failure, wherein the primary process controller cyclically executes the process control tasks during base control cycles having a period, T. The system comprises 1) a tracking circuit operable to detect changed data in a main memory in the primary process controller; 2) a data buffer for temporarily storing the changed data; and 3) data transfer circuitry for transferring the changed data in the data buffer to a backup memory in the backup process controller at least once during each base control cycle of the primary process controller, such that the transfer of changed data does not interfere with execution of the process control tasks.

International Classification:

G05B 19/418

Abstract:

Methods and systems for synchronizing controllers in an automation control system, can involve arranging redundancy elements in an automation control system comprising a group of nodes, wherein the redundancy elements can include one or more primary controllers and a group of concurrent secondary controllers, and wherein a back-up to the primary controller can exist on any node. Such methods and systems can further involve backing-up of the primary controller by the one or more secondary controllers to allow the primary controller to maintain the one or more secondary controllers as a new, alternate secondary controller for a load balancing or an equipment update

International Classification:

H04W 80/00

US Classification:

370338

Abstract:

A method includes receiving data from multiple wireless field devices using multiple wireless communication protocols. The method also includes normalizing the data from the wireless field devices using one or more templates associated with the wireless field devices. The method further includes transmitting the normalized data in a unified format. The method could also include generating the one or more templates using device description (DD) files associated with the wireless field devices. Each template may provide, for one wireless field device or type of wireless field device, (i) an indication of a type of data provided by the wireless field device or type of wireless field device, (ii) a range of data provided by the wireless field device or type of wireless field device, and (iii) how to normalize data from the wireless field device or type of wireless field device into the unified format.
