Abstract

See full text

A daisy chained ethernet network data acquisition system for use in industrial processes is shown. The system employs standard category five twisted-pair connectors, each having four twisted-pairs associated therewith. Two of the twisted-pairs are employed for transmitting and receiving command signals and data, while the remaining two are employed for transmitting a common clock and synchronizing signal to each of the various stages of the processing line at which data is to be acquired. The system thus allows for the time correlated acquisition of data from a plurality of stages or stations of a lengthy processing line by employing ethernet interconnection.
