Efficient Real-Time Industrial Ethernet Links

Real-time Industrial Ethernet (RE), especially IEC 61158, plays increasing role in industrial communications these days, so our motto is to concentrate on Energy efficiency of interest for industrial communications. The alteration introduces a new operational mode, well-defined as Low Power Idle (LPI) that permits to noticeably reduce the power consumption of inactive Ethernet links. We flinch with an explanation of the EEE basics and, afterward, emphasis on the overview of EEE in the industrial communication scenario. Then, we explicitly address the carrying out of effective EEE strategies for some widespread RTE networks.
