An Advanced Physical Layer (APL) adapter for enabling functional interconnection of a 2-wire APL spur to at least one industrial process legacy field device includes a first pair of terminals, APL physical layer (PHY) circuitry, a second pair of terminals and connectivity circuitry. The first pair of terminals is configured for connection to the 2-wire APL spur. The APL PHY circuitry is capacitively coupled to the first pair of terminals. The connectivity circuitry is configured to communicate with a legacy field device connected to the second pair of terminals in accordance with a legacy communication protocol and control the APL PHY circuitry to communicate through the first pair of terminals in accordance with an Ethernet protocol.

Advanced physical layer (APL) adapter for legacy field devices

A system to configure a field device of the type used to calculate a flow of a process fluid. The system includes a flow repository comprising a list of process fluids with which the field device can be used, fluid equation data which provides information related to fluid equations for calculating fluid parameters of the process fluid, a list of primary elements, and primary element equation data which provides information related to primary element equations and fluid equations for calculating flow of the process fluid. The flow application is adapted to retrieve data from the flow repository and to generate information which is used by field device to calculate the flow of the process fluid.
