Abstract
More efficient data transmission of safety-relevant data is achieved by a method for transmitting data between the central control apparatus and a plurality of decentralized devices, which includes generating, in the central control apparatus, a data telegram for the broadcast or multicast transmission of data to a plurality of devices, unidirectionally transmitting the data telegram from the central control apparatus to at least one decentralized device, monitoring the transmission duration of the transmission of the data telegram from the central control apparatus to the at least one decentralized device, and triggering a predetermined safety reaction if the transmission duration exceeds a predefined value. Further, a control and data transmission system designed to carry out the method, and means belonging to such a system.
