Abstract: A positioner for a process plant, such as a chemical plant, a power plant, or a food processing plant, may include a control valve for controlling a process fluid flow of the process plant, a pneumatic actuator for actuating the control valve, and positioner electronics for determining and providing a pneumatic control signal for the actuator based on a control variable. The positioner electronics may include a signal receiving interface for receiving the control variable. The positioner electronics may include a computing device configured to determine at least one simulation parameter that characterizes a signal response of the positioner to a received control variable. The positioner electronics may include a signal output interface for outputting the at least one simulation parameter.
