Abstract

Disclosed herein are methods, apparatus and articles of manufacture for configuring a communication network associated with a plurality of wireless enabled field devices. The disclosed methods, apparatus and articles of manufacture may compare identification information associated with a wireless enabled field device to configuration database information. Configuration information associated with the wireless enabled field device may be retrieved based on the comparison of the identification information to the configuration database information. The retrieved configuration information is sent to the wireless enabled field device via at least one wireless communication link to configure the wireless enabled field device.

Claims

1. A method of configuring a wireless enabled field device, comprising:

receiving identification information associated with the wireless enabled field device in a controller within a process control system, wherein the wireless enabled field device is at least one of a sensor or an actuator;

comparing the identification information to configuration database information;

retrieving via the controller configuration information associated with the wireless enabled field device based on the comparison of the identification information to the configuration database information;

updating a consolidated list of currently active wireless enabled field devices with the identification information associated with the wireless enabled field device; and

sending the configuration information to the wireless enabled field device via at least one wireless communication link to communicatively couple the wireless enabled field device to the controller based on the configuration information.

2. A method as defined in claim 1, wherein the identification information includes a device tag.

3. A method as defined in claim 1, wherein comparing the identification information to the configuration database information includes determining if at least a portion of the identification information matches at least a portion of the configuration database information.

4. A method as defined in claim 1, wherein receiving the identification information associated with the wireless enabled field device includes receiving a list containing identification information associated with a plurality of wireless enabled field devices.

5. A method as defined in claim 4, further including updating a consolidated list of currently active wireless enabled field devices based on the list containing identification information associated with the plurality of wireless enabled field devices.

6. A method as defined in claim 1, wherein receiving the identification information associated with the wireless enabled field device includes receiving at least one message from a controller communicatively coupled to the wireless enabled field device.

7. A method as defined in claim 1, wherein sending the configuration information to the wireless enabled field device includes sending the configuration information via the at least one wireless communication link and a second wireless communication link.

19. A method as defined in claim 1, wherein the wireless enabled field device is configured by causing the storage or activation of a control strategy or at least one parameter on the wireless enabled field device.

20. A method as defined in claim 1, wherein the controller receives the identification information via a wireless broadcast from the wireless enabled field device.

8. An apparatus for configuring a wireless enabled field device, comprising:

a memory; and

a processor coupled to the memory, wherein the processor is programmed to;

receive identification information associated with the wireless enabled field device, wherein the wireless enabled field device is at least one of a sensor or an actuator;

compare the identification information to configuration database information;

retrieve configuration information associated with the wireless enabled field device based on the comparison of the identification information to the configuration database information;

update a consolidated list of currently active wireless enabled field devices with the identification information associated with the wireless enabled field device; and

send the configuration information to the wireless enabled field device via at least one wireless communication link to communicatively couple the wireless enabled field device to the processor based on the configuration information.

9. An apparatus as defined in claim 8, wherein the identification information includes a device tag.

10. An apparatus as defined in claim 8, wherein the processor is programmed to compare the identification information to the configuration database information by determining if at least a portion of the identification information matches at least a portion of the configuration database information.

11. An apparatus as defined in claim 8, wherein the processor is programmed to receive the identification information associated with the wireless enabled field device by receiving a list containing identification information associated with a plurality of wireless enabled field devices.

12. An apparatus as defined in claim 11, wherein the processor is programmed to update a consolidated list of currently active wireless enabled field devices based on the list containing identification information associated with the plurality of wireless enabled field devices.

13. An apparatus as defined in claim 8, wherein the processor is programmed to receive the identification information associated with the wireless enabled field device by receiving at least one message from a controller communicatively coupled to the wireless enabled field device.

14. An apparatus as defined in claim 8, wherein the processor is programmed to send the configuration information to the wireless enabled field device by sending the configuration information via the at least one wireless communication link and a second wireless communication link.

15. A machine readable medium having instructions stored thereon that, when executed, cause a machine to at least:

receive identification information associated with the wireless enabled field device, wherein the wireless enabled field device is at least one of a sensor or an actuator;

compare the identification information to configuration database information;

retrieve configuration information associated with the wireless enabled field device based on the comparison of the identification information to the configuration database information;

update a consolidated list of currently active wireless enabled field devices with the identification information associated with the wireless enabled field device; and

send the configuration information to the wireless enabled field device via at least one wireless communication link to configure and initiate communication of the wireless enabled field device in a process control system.

16. A machine readable medium as defined in claim 15 having instructions stored thereon that, when executed, cause the machine to compare the identification information to the configuration database information by determining if at least a portion of the identification information matches at least a portion of the configuration database information.

17. A machine readable medium as defined in claim 15 having instructions stored thereon that, when executed, cause the machine to receive the identification information associated with the wireless enabled field device by receiving a list containing identification information associated with a plurality of wireless enabled field devices.

18. A machine readable medium as defined in claim 17 having instructions stored thereon that, when executed, cause the machine to update a consolidated list of currently active wireless enabled field devices based on the list containing identification information associated with the plurality of wireless enabled field devices.

21. A machine readable medium as defined in claim 15 having instructions stored thereon that, when executed, cause the machine to initiate communication of the wireless enabled field device by communicatively coupling the wireless enabled field device to a process control controller based on the configuration information.
