Abstract
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.
Claims15
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.
