Abstract

A device and method calculates and sends a manipulated variable via a network to control an actuator in a process. An indication identifying when the sent manipulated variable was applied by the actuator is received, and an applied actuator signal is estimated. Using a difference between the calculated manipulated variable and the estimated applied signal, a next calculated manipulated variable is corrected prior to sending the next calculated manipulated variable to the actuator.
