Abstract:
A disclosed example apparatus includes a first interface to be 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 the first field device and communicates using a second fieldbus communication protocol when coupled to the 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 is to use the third communication protocol to communicate second information received from the other one of the first field device or the second field device.
