Stage with moving parts

Abstract

A device for constructing a stage includes fixed stage parts and movable stage parts. The device includes a set of actuators provided to be physically connected to the movable stage parts and each including a communication module for communicating with a server. The server includes a central communication module for communicating with communication modules of the actuators. A controller is connected to the server and has an operator interface including input means and visualizing means. The controller and server are configured to generate control signals for each actuator on the basis of an input via the input means. Control signals include a safety parameter which indicates a safety level, and an operator can activate different safety levels with different keys. The device is provided to execute control signals with a safety parameter which corresponds to the activated safety level.
