Abstract

An automation component configured for wireless communication within a building automation system includes a wireless communications component, a processor in communication with the wireless communications component, and a memory in communication with the processor. The memory configured to store computer readable instructions which are executable by the processor to process a change-of-value message received via the wireless communications component, generate a change-of-value update in response to the change-of-value message, and communicate the change-of-value update via the wireless communication component. This change-of-value can occur in a polled (pull) fashion, or in a pushed (when it occurs) fashions.

Claims

1. An automation component configured for wireless communication within a building automation system, the automation component comprising:

a wireless communications component;

a processor in communication with the wireless communications component;

a memory in communication with the processor, the memory configured to store computer readable instructions which are executable by the processor;

wherein the computer readable instructions are programmed to;

process a change-of-value request message received via the wireless communications component;

generate a change-of-value update in response to the change-of-value request message; and

communicate the change-of-value update via the wireless communication component.

2. The automation component of claim 1, wherein the change-of-value message is received from a wireless device.

3. The automation component of claim 2, wherein the wireless device is selected from the group consisting of:

a ZigBee-compliant device, a terminal equipment controller, a wireless room temperature sensor, a reduced function device and a full function device.

4. The automation component of claim 1, wherein the change-of-value update includes a plurality of change-of-value messages received from a plurality of wireless devices.

5. The automation component of claim 1, wherein the change-of-value update is a change-of-value response message.

6. The automation component of claim 1, wherein the change-of-value update is automatically communicated.

7. The automation component of claim 1, wherein the change-of-value update is pulled to a field panel transceiver in response to the reception of the change-of-value message by the wireless communication component.

8. The automation component of claim 1, wherein the computer readable instructions are further programmed to:

process an acknowledgment message communicated by the field panel transceiver in response to the change-of-value update.

9. A method of communicating information between automation components operating within a building automation system, the method comprising:

detecting an indication representing a change-of-value;

generating a change-of-value message;

communicating the change-of-value message in response to the detected indication; and

receiving an acknowledgment of the communicated change-of-value message.

10. The method of claim 9, wherein the indication is selected from the group consisting of:

a sensor reading, a temperature indication, and an actuator position.

11. The method of claim 9, wherein generating the change-of-value message includes generating a change of value update comprising a plurality of change-of-value messages.

12. The method of claim 9, wherein the change-of-value message includes the change-of-value and a device indicator.

13. The method of claim 9, wherein communicating the change-of-value message includes automatically communicating the change-of-value-message.

14. The method of claim 9, wherein communicating the change-of-value message includes pushing the change-of-value-message to a communicatively coupled wireless device.

15. An automation component configured for wireless communication within a building automation system, the automation component comprising:

a wireless communications component;

a processor in communication with the wireless communications component;

a memory in communication with the processor, the memory configured to store computer readable instructions which are executable by the processor;

wherein the computer readable instructions are programmed to;

receive at least one change-of-value update via the wireless communications component;

storing the at least one change-of-value update corresponding to at least one wireless device; and

communicate the at least one change-of-value update in response to a polling request.

16. The automation component of claim 15, wherein the change-of-value update is received from a wireless device selected from the group consisting of:

a ZigBee-compliant device, a terminal equipment controller, a wireless room temperature sensor, a reduced function device and a full function device.

17. The automation component of claim 15, wherein the change-of-value update includes a plurality of change-of-value messages.

18. The automation component of claim 15, wherein the change-of-value update is a pushed communication.

19. The automation component of claim 15, wherein the computer readable instructions are further programmed to:

communicate an acknowledgment in response to the received at least one change-of-value update.

20. A method of communicating information between automation components operating within a building automation system, the method comprising:

receiving a change-of-value message representing a wireless device indication;

storing the received change-of-value message according to the corresponding wireless device; and

communicating a change of value update that includes the change-of-value message.

21. The method of claim 20, wherein the wireless device indication is selected from the group consisting of:

a sensor reading, a temperature indication, and an actuator position.

22. The method of claim 20, wherein communicating the change-of-value message includes communicating the change of value update comprising a plurality of change-of-value messages.

23. The method of claim 20, wherein the change-of-value message includes the change-of-value and a device indicator.

24. The method of claim 20, wherein communicating the change-of-value message includes automatically communicating the change-of-value-update.

25. The method of claim 20, wherein communicating the change-of-value update includes pushing the change-of-value-update to a communicatively coupled wireless device.
