Replacing a controller on a process device
View Patent ↗A method for replacing a controller on a process device that avoids downtime on a process line. The method may include retrieving data from a first controller on a valve assembly, the data comprising information that defines values for operating parameters on the first controller, removing the first controller from the valve assembly, coupling a second controller to the valve assembly, and storing data on the second controller, the data comprising information that defines the values for operating parameters corresponding with the first controller.
1. A method, comprising:
at a computing device having a processor with access to executable instructions for,
identifying a change in a valve assembly to a locked position that prevents movement of a closure member relative to a seat;
receiving a first set of data from a first controller on the valve assembly, the data comprising information that defines values for operating parameters on the first controller;
instructing an end user to remove the first controller from the valve assembly;
identifying a change from the first controller with a second controller on the valve assembly;
generating a second set of data for use with the second controller on the valve assembly, the data comprising information that defines the values for operating parameters corresponding with the first controller; and
adjusting an upper stop limit and a lower stop limit on the second controller by,
actuating components on the valve assembly using the second controller;
obtaining position information for the closure member from the second controller; and
recalculating the upper stop limit and the lower stop limit using the position information.
2. The method of claim 1 , further comprising:
writing the first set of data to a repository that is remote from the first controller.
3. The method of claim 1 , further comprising:
transmitting the second set of data to the second controller.
4. The method of claim 1 , further comprising:
instructing the end user to change the valve assembly from the lock position to an unlocked position.
5. The method of claim 1 , further comprising:
changing the valve assembly from the locked position to an unlocked position.
6. The method of claim 1 , further comprising:
instructing the end user to move the closure member relative to the seat.
7. The method of claim 1 , further comprising:
moving the closure member relative to the seat.
8. The method of claim 1 , further comprising:
instructing the end user to indicate that the second controller is in position on the valve assembly.
9. The method of claim 1 , further comprising:
receiving confirmation that the second controller is in position on the valve assembly.
10. The method of claim 1 , further comprising:
confirming that the second controller is in position on the valve assembly.
11. The method of claim 1 , further comprising:
receiving confirmation from the end user that the values in the first set of data are correct.
12. The method of claim 1 , further comprising:
confirming identifying information on the second controller corresponds with identifying information from the first controller.
13. The method of claim 1 , further comprising:
receiving identifying information from the second controller; and
instructing an end user to confirm that the identifying information corresponds with identifying information from the first controller.
14. The method of claim 1 , further comprising:
confirming firmware on the second controller corresponds with firmware on the first controller.
15. The method of claim 1 , further comprising:
causing the first controller to transmit the first set of data.
