Abstract
A controller is configured to perform in-situ testing on a control valve. These configurations can generate a signal that changes position of a closure member in the valve during operation of a process. These changes exercise components of the valve for a short period of time. This testing may result in data that can indicate whether the device is operating properly or may be in need of maintenance or repair.
