Abstract
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.
