Abstract
Systems and methods may be provided to execute online tests of a valve in a digital valve positioner. The digital valve positioner may receive a request to execute a test of the valve, which specifies a test start point, and queue the request for execution. The digital valve positioner may subsequently receive a new setpoint for the valve. The digital valve positioner may further reposition the valve according to the new setpoint. The digital valve positioner may further, while the valve is being repositioned, compare the test start point to a current position of the valve, and in response to determining that the current position of the valve has reached the test start point, collect sensor data indicative of the operation of the valve, to generate results of the test.
