  • Spur isolation in a fieldbus network
    Patent number: 10396854
    Abstract: A method for providing galvanic isolation between an input or trunk interface (30) and multiple outputs or spur interfaces (38) for connecting field devices (14) to a trunk (20) of a two-wire (44a, 44b) process control network (10) includes connecting multiple sets of multiple spur interfaces to respective isolating elements (34). Each isolating element (34) connects a respective set of outputs or spur interfaces (38) to the trunk interface (30) and galvanically isolates (40, 42) the respective set of spur interfaces (38) from the trunk interface (30). Field devices (14) attached to different sets of spur interfaces are also galvanically isolated from one another.

  • Fieldbus network with two-wire loop
    Patent number: 10296483
    Abstract: A fieldbus coupler for coupling a local fieldbus network utilizing a first fieldbus protocol to a foreign field device or foreign fieldbus network through an interconnecting wired or wireless network transmission line that utilizes a second fieldbus protocol different from the first fieldbus protocol includes a first circuit configured to communicate over the local fieldbus network using the first fieldbus protocol, a second circuit configured to connect the fieldbus coupler with the interconnecting network transmission line and communicate over the interconnecting network transmission line using the second fieldbus protocol, and a third circuit configured to communicate with the first and second circuits and capable of transmitting data to and from the first and second circuits to enable communications between the local fieldbus network via the interconnecting network transmission line.
