1. A system for monitoring a condition of a valve, the system comprising:
- a valve having a variable position;
a valve positioner that receives a control instruction, that varies the position of the valve, that determines a condition of the valve, and that transmits the condition;
a sensor server that receives the condition, that transmits a data stream including the condition, that receives a control instruction from a control system, and that transmits the control instruction to the valve positioner; and
an assessment application that receives the data stream and that assesses the condition of the valve by comparing the data stream to a predictive model.

Abstract
System and method for monitoring and controlling one or more valves. The method can include sensing a condition of a valve, transmitting the condition to a sensor server, and transmitting a data stream including the condition to an assessment application. The method can also include generating a predictive model and comparing the condition to the predictive model. The method can further include transmitting a control instruction to at least one of a valve positioner and the sensor server and varying the position of the valve based on the control instruction.

23. A system for monitoring a condition of each one of a plurality of valves, each one of the plurality of valves having a variable position, the system comprising:
-
a plurality of valve positioners, each one of the plurality valve positioners determining a condition for each one of the plurality of valves, transmitting the condition, receiving a control instruction, and changing the position of one of the plurality of valves; a sensor server receiving the condition from each one of the plurality of valve positioners, transmitting a data stream including the condition, receiving the control instruction from a control system, and transmitting the control instruction to one of the plurality of valve positioners; and an assessment application receiving the data stream and assessing the condition of one of the plurality of valves by comparing the data stream to a predictive model. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44)

66. A system for monitoring a condition of a valve, the system comprising:
-
a valve having a variable position; a valve positioner that receives a control instruction, that varies the position of the valve, that determines a condition of the valve, and that transmits the condition in a Highway Addressable Remote Transducer protocol signal; a sensor server that receives the condition, that transmits a substantially continuous data stream including the condition, that receives a control instruction from a control system, and that transmits the control instruction to the valve positioner, the control instruction and the condition being transmitted between the sensor server and the valve positioner on a single transmission line; and an assessment application that receives the substantially continuous data stream over an Object Linking and Embedding for Process Control link and that assesses the condition of the valve by comparing the data stream to a predictive model.
