Abstract: A Safety Instrumented System (200) for use with a process control system receives pressure of process fluid in the process piping (206). A valve positioner (204) positions a valve (212) which controls flow of process fluid through the process piping (206). The valve positioner (204) is caused to perform a partial stroke of the valve (212) or otherwise introduce a perturbation into the process. A resulting change (214) in sensed pressure due to the perturbation is used to diagnose operation of the process.
