摘要： A data bus subscriber connected to a local bus, particularly a ring bus. The data bus subscriber has a status signal input for receiving a first status signal value from a downstream data bus subscriber or a terminator, a status signal output for providing a second status signal value to an upstream data bus subscriber or to a local bus master, wherein the data bus subscriber is adapted to provide the second status signal value based on a logical link of a communication readiness of the data bus subscriber and the first status signal value. The invention further relates to a corresponding method and a local bus.

摘要： A module unit for connecting a data bus participant to a local bus. The module unit has a first input interface and a first output interface which can be connected to the local bus, a first data connection interface which can be connected to the data bus participant, and a first switch which is adapted so as to assume a first or a second switch state depending on a control input from the data bus participant, connect the first input interface to the first output interface in the first switch state, and connect the first data connection interface to the first output interface in the second switch state.

摘要： A device for coupling a fieldbus to a local bus for connection to at least one data bus subscriber, the device comprising a first unit that is connectable to the fieldbus and is adapted for sending and receiving data via the fieldbus; a second unit that is connectable to the local bus and is adapted for sending and receiving data via the local bus in at least one data packet; a data management unit that is connected to the first unit and the second unit, wherein the data management unit is adapted for transferring first symbols from data received via said first unit to said second unit in a sequence-dependent manner; and wherein the second unit is adapted to send at least one data packet including the first symbols on the local bus. In addition, a corresponding method for transferring data is described.

摘要： A coupler for an automation system for controlling a process having a network interface for connection to an Ethernet-based network for receiving an Ethernet telegram having process data of the process and having control data. A local bus interface connects to a local bus for transmitting a local bus telegram. A circuit is formed between the network interface and the local bus interface. The circuit includes an arithmetic circuit for retrieving the process data from a payload data area of the Ethernet telegram. The circuit includes a first data filter circuit, which differs from the arithmetic circuit, for filtering out a predetermined subset of the control data from a header of the Ethernet telegram preceding the payload data area. The circuit is configured to generate the local bus telegram and to insert the process data and the predetermined subset of the control data into the local bus telegram.

摘要： A coupler for an automation system for controlling a process, having a first interface for connection to a field bus for receiving a field bus message with process data of the process, a second interface for connection to a local bus for transmitting a local bus message, and a circuit implemented between the first interface and the second interface. The circuit has a non-clocked logic circuit comprising a number of hardware logic elements. The non-clocked logic circuit is equipped to change process data received through the first interface. The circuit is equipped to output the changed process data in the local bus message.
