Abstract: A control system regulating the transverse profile of properties of a web in a paper or board machine is disclosed. The control system comprises a plurality of actuators and a corresponding plurality of actuator controllers. The actuators are arranged to be effective across the width of the web whose profile is to be regulated. Further included is a process controller and a feedback network connected to the process controller and provided with an arrangement for measuring the web profile to be regulated. The actuators are provided with intelligent actuator controllers. A data bus common to the actuator controllers is provided, along which occur data communications in a control hierarchy between a higher control device and said actuator controllers.
