Beschreibung
Zusammenfassung:	The invention relates to an apparatus and method for communicatively coupling a field device to a controller in a process control system. A disclosed example apparatus includes a first interface communicatively coupled to one of a first field device or a second field device. The first interface communicates using a first fieldbus communication protocol when coupled to a first field device and a second fieldbus communication protocol when coupled to a second field device. The example apparatus includes a communication processor to encode first information received from the one of the first field device or the second field device for communication via a bus using a third communication protocol. The example apparatus includes a second interface communicatively coupled to the communication processor and the bus to communicate the first information to a controller in the process control system. The bus transmits second information received from the other of the first field device or the second field device using a
