communication rate can be up to 12MB. PROFIBUS is used to connect distributed i/0 stations, field bus instruments and other intelligent devices. The communication among process station, operator station and engineer station is realized through the system bus diginets (Industrial Ethernet). user Different transmission media (RJ45 twisted pair, thin cable, thick cable or optical fiber…
