Industrial Switch of Highest Level EMC Standards Creates

Distribution Automation Communication Network

• Distribution automation depends on reliable means of communication to distribute control command from the control center to each executive institution or remote terminals, while uploading several kinds of information collected by each remote supervision unit to the control center.
• The communication system is a key part in intelligent distribution automation, acting as the nervous system of the latter. The basic requirements of distribution automation to the communication system are stability, reliability, real-time transmission, security, and can support 2-way communication. Also, as the nodes participating in communication are in big numbers and widely distributed, it also requires the communication system to be easy to construct, flexible to expand and easy to maintain.
• Industrial Ethernet can well meet the above needs. The adoption of industrial Ethernet networking has become a major solution in the distribution automation communication.

Network Topology
