Abstract

A system, method, and an apparatus relating to automatically setting up pre-upset warning conditions for entire systems based on drifting parameters. The drifting parameters may provide monitoring to operate the process so that the upset condition is never reached, by allowing the operator can take actions so that the process remains in a stable state. The aim is to monitor and limit variations in parameters to enable the operator to achieve a much tighter control on the process and not allow the alarm to occur in the first place. Additionally, the important values may be displayed in context, and the operator may directly manipulate the values through a variety of touch input.

Claims

1. A method for setting drift warnings for monitoring processes that are applicable to a plant operating according to a process control and having a plurality of field devices, the method comprising:

configuring a desired range for an acceptable drift range of a plant process;

setting a desired parameter value for the operating of the plant process;

detecting an actual parameter value of the plant process;

comparing the actual parameter value to the desired parameter value and the desired range; and

displaying an indication of a drift occurrence when the actual parameter value is within the desired range but different from the desired parameter value.

2. The method according to claim 1, further comprising:

automatically adjusting a field device parameter to maintain the actual parameter value at the desired parameter value.

3. The method according to claim 1, wherein at least one of an adjustment of the desired parameter value and drift range is by a touch input of an operator.

4. The method according to claim 3,

wherein the adjustment occurs through at least two touch inputs,

wherein a first touch input is configured to make the adjustment at a first rate corresponding to the movement of the touch input of the operator, and

wherein a second touch input is configured to make the adjustment at a second rate, proportionally different from the first rate, corresponding to the movement of the touch input of the operator.

5. The method according to claim 1, further comprising recording a current desired parameter value of the process.

6. The method according to claim 1, further comprising saving the desired parameter value and the desired range into a configuration file.

7. The method according to claim 1, further comprising:

recording a desired parameter value of the plant process,

wherein the plant process is selectable from a hierarchy of levels of plant processes such that the recording is configured to record the desired parameter value of the plant process and desired parameter values of associated lower level plant processes.

8. A system comprising at least one device for setting drift warnings for monitoring processes in a plant operating according to a process control and having a plurality of field devices, the system comprising:

at least one non-transitory computer readable medium operable to store program code;

at least one processor operable to read said program code and operate as instructed by the program code, the program code comprising;

configuring a desired range for an acceptable drift range of a plant process;

setting a desired parameter value for the operating of the plant process;

detecting an actual parameter value of the plant process;

comparing the actual parameter value to the desired parameter value and the desired range; and

displaying an indication of a drift occurrence when the actual parameter value is within the desired range but different from the desired parameter value.

9. The system according to claim 8, the program code further comprising:

automatically adjusting a field device parameter to maintain the actual parameter value at the desired parameter value.

10. The system according to claim 8, wherein at least one of an adjustment of the desired parameter value and drift range is by a touch input of an operator.

11. The system according to claim 10,

wherein the adjustment occurs through at least two touch inputs,

wherein a first touch input is configured to make the adjustment at a first rate corresponding to the movement of the touch input of the operator, and

wherein a second touch input is configured to make the adjustment at a second rate, proportionally different from the first rate, corresponding to the movement of the touch input of the operator.

12. The system according to claim 8, the program code further comprising recording a current desired parameter value of the process.

13. The system according to claim 8, the program code further comprising saving the desired parameter value and the desired range into a configuration file.

14. The system according to claim 8, the program code further comprising:

receiving a device identifier associated with a process management console;

retrieving configuration data for connection to the process management console; and

automatically configuring the system to connect to the process management console based on the configuration data,

wherein the process management console provides information regarding the process to the system.

15. An apparatus for setting drift warnings for monitoring processes in a plant operating according to a process control and having a plurality of field devices, the apparatus comprising:

at least one non-transitory computer readable medium operable to store program code;

at least one processor operable to read said program code and operate as instructed by the program code, the program code comprising;

configuring a desired range for an acceptable drift range of a plant process;

setting a desired parameter value for the operating of the plant process;

detecting an actual parameter value of the plant process;

comparing the actual parameter value to the desired parameter value and the desired range; and

displaying an indication of a drift occurrence when the actual parameter value is within the desired range but different from the desired parameter value.

16. The apparatus according to claim 15, the program code further comprising:

automatically adjusting a field device parameter to maintain the actual parameter value at the desired parameter value.

17. The apparatus according to claim 15, wherein at least one of an adjustment of the desired parameter value and drift range is by a touch input of an operator.

18. The apparatus according to claim 17,

wherein the adjustment occurs through at least two touch inputs,

wherein a first touch input is configured to make the adjustment at a first rate corresponding to the movement of the touch input of the operator, and

wherein a second touch input is configured to make the adjustment at a second rate, proportionally different from the first rate, corresponding to the movement of the touch input of the operator.

19. The apparatus according to claim 15, the program code further comprising recording a current desired parameter value of the process.

20. The apparatus according to claim 15, the program code further comprising saving the desired parameter value and the desired range into a configuration file.

21. The apparatus according to claim 15, the program code further comprising:

receiving a device identifier associated with a process management console;

retrieving configuration data for connection to the process management console; and

automatically configuring the system to connect to the process management console based on the configuration data,

wherein the process management console provides information regarding the process to the system.
