1. A control device for controlling at least one collimator, wherein the collimator has a plurality of parts being designed for collimating and shaping rays, wherein the rays are generated for treating a predefined body part of a patient, wherein the control device comprises
a programmable logic controller,
a plurality of controller nodes,
a plurality of device controllers, and
a plurality of real-time bus interfaces,
wherein the programmable logic controller is designated as a first master device with respect to each of the controller nodes, wherein the programmable logic controller is designed for superordinate control of the plurality of parts of the collimator, wherein each of the controller nodes is designated as a first slave device with respect to the programmable logic controller, wherein the controller node is designated as a second master device with respect to at least one corresponding device controller, wherein the controller node is designed for controlling at least one corresponding part of the collimator, wherein the controller node is connected to the programmable logic controller by one of the real-time bus interfaces, wherein each of the device controllers is designated as a second slave device with respect to a corresponding controller node, wherein each of the device controllers is designed for controlling at least one of an actuator and a sensor, wherein the actuator is designed for adjusting a corresponding part of the collimator, and wherein the sensor is designed for providing data related to at least one of position information or velocity information with respect to the corresponding part of the collimator, wherein the device controller is connected to the corresponding controller node by one of the real-time bus interfaces.
