Industrial Ethernet is far more versatile than the serial interfaces, like RS232, RS422 and RS485, which were employed in industrial automation systems in the past. Through its deployment major improvements can be made to the efficiency of communication infrastructure and markedreductions in day-to-day running costs witnessed.In simple terms it relies on Cat 5 and Cat 6 cables that are identical to the ones used by Ethernet technology in offices, data centers and such like for several decades.
