Abstract

A method for a building system and corresponding data processing system. A method includes receiving, by a data processing system, a building system diagnostics configuration. The method includes receiving diagnostic data corresponding to the building system diagnostics configuration and processing the diagnostic data. The method includes generating a report based on the processed diagnostic data and storing or displaying the report.

Claims

1. A method for a building system comprising the steps of:

receiving, by a data processing system, a building system diagnostics configuration;

transmit, by the data processing system to a field device, a request for diagnostic data based on the building system diagnostic configuration,

receiving, by the data processing system from the field device, the diagnostic data corresponding to the transmitted request, wherein the diagnostic data includes additional data for analysis of the field device in the building system;

processing the diagnostic data by the data processing system, wherein processing the diagnostic data includes determining a delay in propagation of an alarm event over a plurality of networks based on a timestamp of the alarm event appearing on an internal communication network of a first fire panel, a timestamp of an inter-panel communication network, and a timestamp on an internal communication network of a second field device;

verifying a health or condition of the field device using the additional data before a trouble condition is detected;

identifying a potential issue of the field device using the additional data before the building system is aware of an actual issue related to the potential issue and before the building system reports the actual issue;

generating a report based on the processed diagnostic data, the verified health or condition of the field device, and the identified potential issue of the field device by the data processing system, wherein the report indicates the delay in the propagation of the alarm event over the plurality of networks; and

storing or displaying the report by the data processing system.

2. The method of claim 1, wherein the field device is a fire panel.

3. The method of claim 1, wherein:

the building system is a fire alarm system;

the building system diagnostics configuration indicates that network traffic on the plurality of networks should be monitored for alarm events, and communications over the plurality of networks should be logged, time-stamped, and synchronized;

the diagnostics data comprises at least one alarm event that is communicated over the plurality of networks;

processing the diagnostics data includes verifying whether the alarm event is communicated over each of the plurality of networks; and

the report further indicates whether the alarm event is communicated over each of the plurality of networks.

4. The method of claim 1, wherein the building system diagnostics configuration includes an intended scope of a diagnostics.

5. The method of claim 4, wherein the intended scope of the diagnostics identifies the field device, a time to run data collection, and a physical connection that will be monitored.

6. The method of claim 1, wherein the diagnostic data includes data received over a plurality of connected busses, and wherein the data processing system synchronizes timestamps of the received diagnostic data.

7. The method of claim 1, wherein the diagnostic data includes:

a physical input from the field device; and

a physical output from the field device.

8. The method of claim 1, wherein the diagnostic data includes a virtual point associated with a control application or a logic object within a field device.

9. The method of claim 1, wherein processing the diagnostic data includes one or more of performing an analysis of diagnostic data, performing consistency checks of the diagnostic data, detecting unexpected behavior in the diagnostic data, or detecting unexpected data/messages or unusual messages in the diagnostic data.

10. The method of claim 1, wherein processing the diagnostic data includes one or more of identifying unexpected modules or devices from the diagnostic data, identifying missing modules or devices from the diagnostic data, or detecting scrambled messages in the diagnostic data.

11. A building system, comprising:

a data processing system including a processor, and an accessible memory, wherein the processor is configured to;

receive a building system diagnostics configuration,

transmit, to a field device, a request for diagnostic data based on the building system diagnostics configuration,

receive, from the field device, the diagnostic data corresponding to the transmitted request, wherein the diagnostic data includes additional data for analysis of the field device in the building system;

process the diagnostic data, wherein to process the diagnostic data includes determining a delay in propagation of an alarm event over a plurality of networks based on a timestamp of the alarm event appearing on an internal communication network of a first fire panel, a timestamp of an inter-panel communication network, and a timestamp on an internal communication network of a second field device;

verify a health or condition of the field device using the additional data before a trouble condition is detected;

identify a potential issue of the field device before the building system is aware of an actual issue related to the potential issue and before the building system reports the actual issue;

generate a report based on the processed diagnostic data, the verified health or condition of the field device, and the identified potential issue of the field device, wherein the report indicates the delay in the propagation of the alarm event over the plurality of networks; and

store or display the report; and

the field device including a programmable controller, a storage, and a sensor, the programmable controller configured to;

store the diagnostic data related to functions of the field device,

receive the request for diagnostic data from the data processing system, and

transmit the diagnostics data related to the request to the data processing system.

12. The building system of claim 11, wherein the field device is a fire panel.

13. The building system of claim 11, wherein:

the building system is a fire alarm system;

the building system diagnostics configuration indicates that network traffic on the plurality of networks should be monitored for alarm events, and communications over the plurality of networks should be logged, time-stamped, and synchronized;

the diagnostics data comprises at least one alarm event that is communicated over the plurality of networks;

processing the diagnostics data includes verifying whether the alarm event is communicated over each of the plurality of networks; and

the report further indicates whether the alarm event is communicated over each of the plurality of networks.

14. The building system of claim 11, wherein the building system diagnostics configuration includes an intended scope of a diagnostics.

15. The building system of claim 14, wherein the intended scope of the diagnostics identifies the field device, a time to run data collection, and a physical connection that will be monitored.

16. The building system of claim 11, wherein the diagnostic data includes data received over a plurality of connected busses, and wherein the data processing system synchronizes timestamps of the received diagnostic data.

17. The building system of claim 11, wherein the diagnostic data includes:

a physical input from the field device; and

a physical output from the field device.

18. The building system of claim 11, wherein the diagnostic data includes a virtual point associated with a control application or a logic object within a field device.

19. The building system of claim 11, wherein processing the diagnostic data includes one or more of performing an analysis of diagnostic data, performing consistency checks of the diagnostic data, detecting unexpected behavior in the diagnostic data, or detecting unexpected data/messages or unusual messages in the diagnostic data.
