Abstract
A method and apparatus is disclosed that provides a standard interface to process control devices which are adapted to differing field-bus protocols. The techniques disclosed herein enable integration of process control devices adapted to differing field-bus protocols while avoiding the use of protocol gateways which would otherwise greatly complicate the task of developing process control application programs.
