Gateway device having a format adaptation function

A data communication gateway for a construction machine communication system, the gateway comprising a first, a second, and a third data interface arranged to be mutually interconnected, where the mutual interconnect is controlled by a gateway electronic control unit (ECU),

• wherein the first interface is arranged to be connected to a private network of a construction machine, the second interface is arranged to be connected to an attachment network, wherein an attachment comprises a sensor device arranged to generate a sensor signal, and the third interface is arranged to be connected to an auxiliary network,
• wherein a message format table comprising one or more message formats is configured in the gateway ECU, wherein a message format is indicative of a message formatting relative to a standard message format of the construction machine communication system,
• wherein the gateway ECU is arranged to receive a message on a source interface out of the first, second, and third interfaces, translate a data content of the message based on the message format table, and forward a message comprising the translated data content onto a destination interface out of the first, second, and third interfaces, wherein the translation includes the conversion of different sensor signals into a common format, and
• wherein the gateway ECU is arranged to receive an identification signal from the attachment connected to the second interface, wherein the identification signal identifies the attachment, and to configure the message format table in dependence of the received identification signal.
