摘要： An apparatus includes at least one transceiver configured to transmit or receive at least one data signal over a shared physical medium. The physical medium includes a bus configured to be coupled to multiple devices including the apparatus and provides a multi-drop capability. The at least one transceiver is configured to transmit or receive the at least one data signal at a rate of more than 10 Mbps. In some embodiments, the apparatus includes a MAC driver configured to route network layer data over the physical medium. In other embodiments, the apparatus includes a MAC driver configured to control transmissions and receptions of network layer data over the physical medium by the at least one transceiver and a logic device configured to control physical layer signaling, interface with the MAC driver, enable the transmissions and receptions of the network layer data on the physical medium, and implement collision detection and avoidance.

摘要： Communications interface systems and methods for industrial process and manufacturing control. A first infrastructure supports a group of downloadable server protocol applications and a group of downloadable client protocol applications. A second infrastructure supports a group of pluggable hardware interfaces that connect with an underlying communications network. Additionally, a common infrastructure can be configured, which includes a manager and data aggregation layer that connects to and communicates with the group of downloadable server protocol applications and the group of downloadable client protocol applications. The common infrastructure manages and aggregates data between the first infrastructure and the second infrastructure and creates new interface features by plugging in new and/or available components in multiple form factors.
