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
An apparatus, comprising:
- 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.
A system, comprising:
- a valve assembly comprising an actuator, a valve coupled to the actuator, the valve comprising a closure member movable relative to a seat, and a valve positioner coupled to the actuator;
- and
- a computing device connectable to the valve positioner, the computing device comprising a processor with access to executable instructions for,
- identifying a change in the valve assembly to a locked position that prevents movement of the closure member relative to the 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.
