<p>A method and apparatus provides a standard interface (14) to process control devices (20-22) which are adapted to differing field-bus protocols (18). The method and apparatus enable integration of process control devices (20-22) adapted to differing field-bus protocols (18) while avoiding the use of protocol gateways which would otherwise greatly complicate the task of developing process control application programs. <IMAGE></p> |
