Abstract

Sensors of a control system transmit detected cyclical actual states of a technical industrial process to a common central unit via a first protected connection of a first open communication network once within a specified time window. The central unit transmits cyclical control signals commensurate with the actual states to multiple actuators via a second protected connection of a second open communication network once within the specified time window. Each sensor supplies the actual state detected by the sensor to the first open communication network within a respective transmitter-side sub-region within the time window. The central unit receives the transmitted actual states within a respective corresponding receiver-side sub-region within the time window. The transmitter-side sub-regions of the sensors are specified such that the receiver-side sub-regions are disjointed from one another.
