    Abstract: The present invention is directed to facilitating communication within an automation system having a plurality of networks and network protocols. Specifically, a Modbus network is operably connected to a network. A fieldbus coupler operably connected to both networks having a program facilitates communication within the automation system wherein devices connected to the network can be accessed for monitoring and/or controlling via Modbus commands. The fieldbus coupler (FBC) program accepts a Modbus function code containing one or more embedded message of varying types. The FBC program using additional information contained in the Modbus function code and the message type reads or writes only the required information to and from the field devices. This specific read or write request of the information and the embedding of more than one message type reduces overhead and bandwidth usage, thus improving bus response time and efficiency.

    Abstract: A mounting for a package containing a semiconductor chip is disclosed, along with methods of making such a mounting. The mounting includes a substrate having a mounting surface with conductive traces thereon, and an aperture extending through the substrate. The package includes a base, such as a leadframe or a laminate sheet, and input/output terminals. A chip is on a first side of the base and is electrically connected (directly or indirectly) to the input/output terminals. A cap, which may be a molded encapsulant, is provided on the first side of the base over the chip. The package is mounted on the substrate so that the cap is in the aperture, and a peripheral portion of the first side of the base is over the mounting surface so as to support the package in the aperture and allow the input/output terminals of the package to be juxtaposed with to the circuit patterns of the mounting surface. Because the cap is within the aperture, a height of the package above the mounting surface is minimized.
