Abstract: 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.
