The project uses a total of 95 units of MIEN6208-2S-SC20 and 3 units of MIEN6024-8S-SC20. It has 9 ring networks, each switch corresponds to an outdoor room, a collector, a box transformer, two DC cabinets, two inverters and several convergence boxes. Some network lines are equipped with outdoor environmental monitoring devices. The transmission between outdoor collector and bottom devices is RS-485 signal, between switch and collector is Ethernet, between MIEN6208 and MIEN6024 is optical fiber, between MIEN6024 and protocol converter is network cable, and then respectively connect to the background switch in Control Room.
