The Study of Real-Time Industrial Ethernet Power link Medium Redundancy

摘要

This paper analyses the medium redundancy technology in the Industrial Ethernet POWERLINK network. Ethernet data before heading to Media Access Controller, in order to achieve the medium redundancy, we design a Link Selector functional block, it can put three physical networks of the best quality network data to the Media Access Controller. This will ensure the robustness and stability of the physical network. The data delay is only a few microseconds time, does not affect the normal operation of network.
