Abstract

An article of manufacture, method, and system for automatically collecting, formatting, parsing, and transferring data from a distributed control system (DCS) to a diagnosis/analysis program are provided. The article of manufacture embodies an application interface program (API) which, when executed, performs the steps of: automatically collecting, formatting, and parsing process alarms from each DCS node; automatically collecting, formatting, and parsing operator actions from each DCS node using an SQL call; and automatically collecting, formatting, and parsing system monitor messages from each DCS node using an SQL call. The data may be parsed according to the time collection limits between when the API was last run and the current time. In one embodiment, the DCS is Foxboro'"'"'s I/A DCS®, and the collected data is transferred by FTP for transmission over a network, such as the Internet, to a remote diagnosis/analysis program such as Honeywell'"'"'s Control Performance Solution™ including Loop Scout™.

Claims

1. An article of manufacture embodying an application program interface (API) that is executed by a computer, wherein the API allows a distributed control system (DCS) to collect and transfer data therefrom to a diagnosis/analysis program by performing the steps of:

automatically collecting, formatting, and parsing process alarms from each DCS node;

automatically collecting, formatting, and parsing operator actions from each DCS node using an SQL call; and

automatically collecting, formatting, and parsing system monitor messages from each DCS node using an SQL call.

2. The article of claim 1, wherein the API further performs the step of transferring the collected and parsed process alarms, operator actions, and system monitor messages by FTP for transmission over a network.

3. The article of claim 1, wherein the process alarms, operator actions, and system monitor messages are parsed according to time collection limits that are set between the time that the API was last run and the current time.

4. The article of claim 1, wherein the process alarms, operator actions, and system monitor messages are parsed according to time collection limits that are set by a user.

5. The article of claim 1, wherein the DCS comprises Foxboro'"'"'s I/A DCS.

6. The article of claim 1, wherein the diagnosis/analysis program comprises Honeywell'"'"'s Control Performance Solution.

7. The article of claim 1, wherein the API is configured to run periodically according to a predefined schedule.

8. A method for automatically collecting and transferring data from a distributed control system (DCS) to a diagnosis/analysis program, comprising the steps of:

automatically collecting, formatting, and parsing process alarms from each DCS node;

automatically collecting, formatting, and parsing operator actions from each DCS node using an SQL call; and

automatically collecting, formatting, and parsing system monitor messages from each DCS node using an SQL call.

9. The method of claim 8, further performing the step of transferring the collected and parsed process alarms, operator actions, and system monitor messages by FTP for transmission over a network.

10. The method of claim 8, wherein the process alarms, operator actions, and system monitor messages are parsed according to time collection limits that are set between the time that the last data collection occurred and the current time.

11. The method of claim 8, wherein the process alarms, operator actions, and system monitor messages are parsed according to time collection limits that are set by a user.

12. The method of claim 8, wherein the DCS comprises Foxboro'"'"'s I/A DCS.

13. The method of claim 8, wherein the diagnosis/analysis program comprises Honeywell'"'"'s Control Performance Solution.

14. A system for automatically collecting and transferring data from a distributed control system (DCS) to a remote diagnosis/analysis program, comprising:

(a) a DCS including a plurality of DCS nodes, each DCS node being linked to an application program interface (API) that is executed by the DCS node, wherein the API performs the steps of;

(i) automatically collecting, formatting, and parsing process alarms from each DCS node;

(ii) automatically collecting, formatting, and parsing operator actions from each DCS node using an SQL call; and

(iii) automatically collecting, formatting, and parsing system monitor messages from each node using an SQL call;

(b) a network over which the collected and parsed process alarms, operator actions, and system monitor messages are transferred from the DCS; and

(c) a diagnosis/analysis program for receiving the process alarms, operator actions, and system monitor messages from the DCS.

15. The system of claim 14, wherein the process alarms, operator actions, and system monitor messages are parsed according to time collection limits that are set between the time that the API was last run and the current time.

16. The system of claim 14, wherein the process alarms, operator actions, and system monitor messages are parsed according to time collection limits that are set by a user.

17. The system of claim 14, wherein the DCS comprises Foxboro'"'"'s I/A DCS.

18. The system of claim 14, wherein the network comprises the Internet.

19. The system of claim 14, wherein the diagnosis/analysis program comprises Honeywell'"'"'s Control Performance Solution.

20. The system of claim 14, wherein the API is configured to run periodically according to a predefined schedule.
