摘要： An automation system has a master control unit, a first radio subscriber, a first radio device and a clock master. The first radio device has a first synchronization element, a first radio module and a first connection for the bus system. The first radio module can establish a radio connection to the first radio subscriber for data exchange with a bus system provided by the master control unit. The first radio connection has a first radio channel with a first frequency range. The first synchronization element is set up to output a synchronization signal to the first radio module, based on a signal received from the clock master via the first connection. The first radio module is set up to change a frequency of the first radio channel based on the synchronization signal, within the first frequency range, on the basis of a first hopping table.

摘要： In an automation system, a protocol converter is provided between a first network and a second network for converting safety-related messages between the first and second networks that use different network protocols for message exchange. In the protocol converter, a single-channel filter connected to a single-channel interface determines messages having a first safety communication protocol from messages received from the interface over the first network and messages having a second safety communication protocol received over the second network. An at least dual-channel safety module connected to the single-channel filter then converts the messages with the first safety communication protocol determined by the single-channel filter into messages with the second safety communication protocol, or converts the messages with the second safety communication protocol determined by the single-channel filter into messages with the first safety communication protocol.

摘要： In a data-transmission system, a first amount of data can be transmitted in each transmission cycle. A data generator provides a second amount of data for each transmission cycle. The first amount of data exceeds the second amount of data by a percentage. The data generator transmits the data provided by the data generator to a data processor at the data transmission rate of the data-transmission channel. The data processor processes the data received from the data generator on the data-transmission channel, delayed by the number of transmission cycles required for the data generator to respond to a command from the data processor. The data processor indicates a transmission cycle as faulty with the aid of a repeat command if an error has occurred in the data transmission, and the data generator repeats the transmission of the data of the cycle indicated as faulty upon receiving the repeat command.
