Abstract
A distributed control system has a plurality of distributed field devices, each of which contains a transducer and a wireless transceiver. The distributed control system includes a base station transceiver, a database and a virtual transmitter application in communication with the database. Each field device transmits and receives data via wireless signals between the communications boards and the base station. The data is stored in the database for later retrieval and evaluation by the virtual transmitter application. The deployed field device senses information and transmits the sensed information wirelessly to a base station. The sensed information is stored in memory on a computer system, and programmatically groomed to provide a measurement value, upon request by a user.
