Abstract

A method for wireless communication within a building automation system is disclosed. The method includes establishing a communications link between a first automation component and a second automation component, detecting a change in the communications link at the second automation component, and initiating a reset function on the second automation component in response to the detected change in the communications link. A building automation system is further disclosed. The system includes a first automation component, a second automation component in communication with the first automation component via a communication link. The second automation component further includes a reset function stored on a memory and executable by a processor in communication with the memory, such that the reset function is activated in response to a change in the communications link.

Claims

1. A method for wireless communication within a building automation system, the method comprising:

establishing a communications link between a first automation component and a second automation component;

detecting a change in the communications link at the second automation component; and

initiating a reset function on the second automation component in response to the detected change in the communications link.

2. The method of claim 1, wherein the communication link is a communication selected from the group consisting of:

a continuous communication signal;

a periodic communication signal; and

a status query.

3. The method of claim 1, wherein establishing the communication link further comprises:

generating is a communication signal at the first automation component;

communicating the communication signal from the first automation component to the second component via the communication link; and

receiving the communication signal at the second automation component.

4. The method of claim 1, wherein at least one of the first and second automation components is a full function device.

5. The method of claim 1, wherein at least one of the first and second automation components is a reduced function device.

6. The method of claim 1, wherein detecting the change in the communications link includes detecting the absence of the communications link.

7. The method of claim 1, wherein detecting the change in the communications link includes periodically detecting the change according to a timed interval.

8. The method of claim 1, wherein the first automation controller is selected from the group consisting of:

a full function device;

a reduced function device, a terminal, and a portable computer.

9. A building automation system comprising:

a first automation component;

a second automation component in communication with the first automation component via a communication link, the second automation component comprising;

a reset function stored on a memory and executable by a processor in communication with the memory, the reset function activated in response to a change in the communications link.

10. The system of claim 9, wherein the communication link is a communication selected from the group consisting of:

a continuous communication signal;

a periodic communication signal; and

a status query.

11. The system of claim 9, wherein communication link between first automation component and the second automation component is a wired communication link.

12. The system of claim 9, wherein communication link between first automation component and the second automation component is a wireless communication link.

13. The system of claim 9, wherein at least one of the first and second automation components is a full function device.

14. The system of claim 9, wherein at least one of the first and second automation components is a reduced function device.

15. The system of claim 9, wherein activation of the reset function is in response to a null signal associated with communications link.

16. An automation component comprising:

a memory configured to store a reset function;

a processor in communication with the memory and configured to execute the reset function; and

a communication port configured to receive a communication signal, and provide the received communication signal to the processor;

wherein the processor executes the reset function in response to a change in the received communication signal.

17. The component of claim 16, wherein processor includes a timer function having a timed period and wherein the reset function is executed based on the timed period.

18. The component of claim 16, wherein the communication port is a wireless communication port.

19. The component of claim 16, wherein the communication port is a wired communication port.

20. The component of claim 16, wherein the communication signal is a null signal.
