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.

A frequency hopping method and associated apparatus and system using the frequency hopping method are described. The frequency hopping method includes obtaining a key value based on or including a current time value obtained from a current time value source. The key value is used to determine a hop frequency value by querying a data structure stored on a storage medium for a value associated with the key value. The data structure includes a plurality of values, each of which having been generated from a truly random process such that there is no mathematical relationship between the values. A carrier frequency of a transceiver module is set to the hop frequency value for transmitting and receiving radio signals using the carrier frequency.

Multiple transmit and receive channels in a communication transceiver may be dynamically configured using corresponding channel registers. The present disclosure proposes a profile-based direct memory access (PDMA) that can be used to transfer data from a memory and program specific profile registers in a randomly accessed addressing manner. PDMAs can offload the system processor from reprogramming many system registers based on external or internal events in a multi channels communication system. Furthermore, a PDMA based DMA controller is proposed to configure the frequency hopping registers of the transceiver based on PDMA.
