Method and system for retrieving building automation system controller information using near field communication

1. A method for retrieving configuration information for a controller, the method comprising:

verifying login information on a mobile computing device to ensure the mobile computing device has authority to access a wiring diagram;

receiving, by the mobile computing device, identity information associated with the controller via Near Field Communication (NFC) read operations from memory of an NFC tag associated with the controller, which is one of a plurality of controllers in a building automation system, wherein the controller is in installed in a final destination and is in a powered-off state;

retrieving, by the mobile computing device using the identity information, the wiring diagram from a storage medium; and

displaying, by the mobile computing device, the retrieved wiring diagram associated with the controller.

2. The method of claim 1 , wherein the mobile computing device is physically remote from the controller.

3. The method of claim 1 , wherein the step of retrieving the wiring diagram from the storage medium further comprises:

retrieving the wiring diagram from memory of the NFC tag such that the wiring diagram is stored on the NFC tag.

4. The method of claim 1 , wherein the login information includes a username and a password provided to a user interface of the mobile computing device.

5. The method of claim 1 , further comprising:

retrieving, by the mobile computing device from the storage medium, a manual instruction associated with the controller.

6. The method of claim 5 , further comprising:

displaying, by the mobile computing device, the retrieved manual instruction associated with the controller.

7. The method of claim 5 , wherein the manual instruction includes a voice-based instruction for guiding and troubleshooting a connection of cables to the controller.

8. The method of claim 1 , further comprising:

retrieving, by the mobile computing device using the identity information, cable tags associated with cables configured to be connected to the controller, wherein retrieving the identity information comprises retrieving the identity information from the storage medium.

9. The method of claim 8 , further comprising:

displaying, by the mobile computing device, the retrieved cable tags associated with the controller.

10. The method of claim 8 , further comprising:

transmitting, by the mobile computing device, the cable tags to a printer in response to retrieving the cable tags; and

printing, by the printer, the cable tags.

11. The method of claim 8 , further comprising:

revising the cable tags;

storing, by the mobile computing device, the revised cable tags with new identity information associated with the controller; and

storing the new identity information in the memory of the NFC tag for later retrieval operations by the controller.

12. The method of claim 8 , further comprising:

automatically formulating, from a controller program, the cable tags; and

storing the cable tags in the storage medium for later retrieval operations by the mobile computing device.

13. The method of claim 1 , further comprising:

revising the wiring diagram.

14. The method of claim 13 , further comprises:

storing, by the mobile computing device, the revised wiring diagram with new identity information associated with the controller; and

storing the new identity information in the memory of the NFC tag for later retrieval operations by the controller.

15. The method of claim 13 further comprises:

storing the revised wiring diagram in the memory of the NFC tag.

16. The method of claim 1 , further comprising:

retrieving, by the mobile computing device using the identity information, a floorplan associated with a building within which the controller is located, wherein retrieving the floorplan comprises retrieving the floorplan from the storage medium; and

displaying, by the mobile computing device, the retrieved floorplan.

17. A system for retrieving configuration information for a controller, the system comprising: a Near Field Communication (NFC) tag including NFC memory that stores identity information corresponding to the controller, which is one of a plurality of controllers in a building automation system; a storage medium configured to store digital data; and a mobile computing device that includes an NFC transceiver and is configured to receive the identity information from the NFC tag and retrieve a wiring diagram associated with the controller from the storage medium while the controller is in installed in a final destination and is in a powered-off state.

18. The system of claim 17 , wherein the mobile computing device is further configured to receive the identity information from the NFC tag while the mobile computing device is physically remote from the controller.

19. The system of claim 17 , wherein the mobile computing device is further configured to retrieve cable tags associated with cables to be connected to the controller from the storage medium and transmit the cable tags to a printer, and the system further comprises:

the printer being configured to automatically print the cable tags in response to the mobile computing device retrieving the cable tags and transmitting the cable tags to the printer.

20. A system for retrieving configuration information for a controller, the system comprising:

a Near Field Communication (NFC) tag including NFC memory that stores identity information corresponding to the controller, which is one of a plurality of controllers in a building automation system;

a storage medium configured to store digital data; and

a mobile computing device that includes an NFC transceiver and is configured to:

verify login information to ensure the mobile computing device has authority to access a wiring diagram;

receive the identity information from the NFC tag and retrieve a wiring diagram associated with the controller from the storage medium while the controller is installed in a final destination and is in a powered-off state; and

display the retrieved wiring diagram associated with the controller.

21. The system of claim 20 , wherein the mobile computing device is further configured to receive the identity information from the NFC tag while the mobile computing device is physically remote from the controller.
