DISTRIBUTED PROCESS CONTROL SYSTEM AND METHOD UTILIZING WIRELESS COMMUNICATION OF PACKET MESSAGES

摘要

A distributed control and/or monitoring system (10) and method includes a local application (11 ) and a remote application (13) separated from the local application (11). The local application (11) includes a host computer (12). The remote application (13) includes a plurality of field devices (20) and a communication bus (18) connected to the plurality of field devices (20). Packet messages are wirelessly communicated between the local application (11 ) and the remote application (13) such that the host computer (12) and field devices (20) can communicate with each other as if they were directly connected to the same communication bus.
