Abstract

Example methods and apparatus to manage process plant alarms are disclosed. A disclosed example method includes receiving a process plant control system configuration parameter, the process plant control system configuration parameter representing a selected state of a process plant, performing a first query in an alarm definition data structure based on the process plant control system configuration parameter to obtain an alarm configuration parameter for a process plant alarm module of a process plant controller, and configuring a state of the process plant alarm module based on the obtained alarm configuration parameter.

Claims

1. A method comprising:

receiving a process plant control system configuration parameter, the process plant control system configuration parameter representing a selected state of a process plant;

performing a first query in an alarm definition data structure based on the process plant control system configuration parameter to obtain an alarm configuration parameter for a process plant alarm module of a process plant controller; and

configuring a state of the process plant alarm module based on the obtained alarm configuration parameter.

2. A method as defined in claim 1, further comprising:

performing a second query in the alarm definition data structure to obtain a variable representative of an alarm state behavior for the process plant alarm module, the variable representing a configured action of the process plant alarm module in response to a measurable variable of the process plant; and

configuring an operation of the process plant alarm module based on the obtained variable.

3. A method as defined in claim 2, wherein the second query in the alarm definition data structure comprises performing a table lookup based on the obtained alarm configuration parameter.

4. A method as defined in claim 2, further comprising:

performing a third query in the alarm definition data structure to obtain an alarm threshold; and

configuring the operation of the process plant alarm module based on the obtained alarm threshold.

5. A method as defined in claim 1, wherein the alarm configuration parameter comprises at least one of a logging disabled state, an alarm disabled state, a no horn state, a no alarm banner state, an automatic acknowledge state, or an automatic acknowledge inactive state.

6. A method as defined in claim 1, wherein configuring the state of the process plant alarm module comprises configuring a parameter associated with the process plant alarm module.

7. A method as defined in claim 1, wherein the first query in the alarm definition data structure comprises performing a table lookup based on the process plant control system configuration parameter.

8. A tangible article of manufacture storing machine readable instructions that, when executed, cause a machine to:

receive a process plant control system configuration parameter, the process plant control system configuration parameter representing a selected state of a process plant;

perform a first query in an alarm definition data structure based on the process plant control system configuration parameter to obtain an alarm configuration parameter for a process plant alarm module of a process plant controller; and

configure a state of the process plant alarm module based on the obtained alarm configuration parameter.

9. A tangible article of manufacture as defined in claim 8, wherein the machine readable instructions, when executed, cause the machine to:

perform a second query in the alarm definition data structure to obtain a variable representative of an alarm state behavior for the process plant alarm module, the variable representing a configured action of the process plant alarm module in response to a measurable variable of the process plant; and

configure an operation of the process plant alarm module based on the obtained variable.

10. A tangible article of manufacture as defined in claim 9, wherein the machine readable instructions, when executed, cause the machine to:

perform a third query in the alarm definition data structure to obtain an alarm threshold; and

configure the operation of the process plant alarm module based on the obtained alarm threshold.

11. A tangible article of manufacture as defined in claim 8, wherein the alarm configuration parameter comprises at least one of a logging disabled state, an alarm disabled state, a no horn state, a no alarm banner state, an automatic acknowledge state, or an automatic acknowledge inactive state.

12. A tangible article of manufacture as defined in claim 8, wherein the machine readable instructions, when executed, cause the machine to configure the state of the process plant alarm module by configuring a parameter of the process plant alarm module.

13. A tangible article of manufacture as defined in claim 8, wherein the machine readable instructions, when executed, cause the machine to perform the first query in the alarm definition data structure by performing a table lookup based on the process plant control system configuration parameter.

14. An apparatus comprising:

a tangible machine accessible memory;

an alarm behavior rules data structure stored on the machine accessible memory, the alarm behavior rules data structure defining, for a process plant alarm module of a process plant controller, a plurality of alarm configuration parameters for respective ones of a plurality of process plant control system configuration parameters; and

an alarm manager to receive a variable representative of a selected state of a process plant, to obtain an alarm configuration parameter from the alarm behavior rules data structure based on the received variable, and to configure the process plant alarm module based on the obtained alarm configuration parameter.

15. An apparatus as defined in claim 14, wherein the alarm configuration parameter comprises at least one of an alarm behavior state, an action in response to a measurable variable of the process plant, or an alarm threshold.

16. An apparatus as defined in claim 14, wherein the alarm parameter data structure is stored on the tangible machine accessible memory.

17. An apparatus as defined in claim 14, wherein the alarm behavior rules data structure comprises a tabular data structure, wherein the alarm manager is to obtain the alarm configuration parameter by performing a lookup of the tabular data structure based on the variable representative of the selected state of the process plant.
