1. An electrical device (LNK) with a first communications interface (K′
- ) and with a first communications component (DP-S) for a communications connection to a first bus (DP), and with a second communications interface (K) and with further communications components (PA-M, FF-M) for a communications connection to a further bus (PAFF), characterized in that the first bus and the further bus are field buses, and that the electrical device (LNK) is provided to address not only a device (PA-G) which is connected to the further field bus (PAFF) and can be addressed by means of a first protocol (PA-P), but also a device (FF-G) which is likewise connected to the further field bus (PAFF) and can be addressed by means of a second protocol (FF-P), whereby the addressing of the first device (PA-G) which can be addressed by means of the first protocol (PA-P) and the addressing of the second device (FF-G) which can be addressed by means of the second protocol (FF-P) are carried out alternately in a time-slice method, and whereby the second communications interface (K) is provided for joint access by the further communications components (PA-M, FF-M) to the further field bus (PAFF) and the respective devices (PA-G, FF-G) connected to the further field bus (PAFF).

Abstract
The invention relates to an electrical device (LNK) which has means (DP-S, K′) for forming a communication connection to a field bus (DP) and additional means (PA-M, FF-M, K) for forming a communication connection to an additional field bus (PAFF). Said device is thus presented as a combination of three communication stations (DP-S, PA-M, FF-M) for the respective connection to a field bus (DP, PA, FF).
