Abstract
A multi-protocol interface for coupling a field device to a general purpose computer is disclosed. The interface includes measurement circuitry to perform a plurality of measurements on a connected process communication loop to determine a process communication loop type. Then, if the interface includes a protocol interface module that matches the detected loop type, the protocol interface module can be engaged. A method for coupling a field device to a general purpose computer is also provided. In one aspect, power from the general purpose computer is used to power the process communication loop, if the interface determines that the loop is not powered.
