The system uses a clear two-tier network, the upper computer between the use of Ethernet, the controller between the mining 10M high-speed MELSECNET / 10 dual-ring cable network.
MELSECNET / 10 control network with loop switching, loop loopback and floating master and other functions to ensure that the entire control system with a high degree of security and reliability.
By installing the MELSECNET / 10 network PCI communication board on the host computer, you can connect the supervisory computer directly to the 10 network, so as to ensure the real-time performance of the host computer.
Local PLC control station configuration serial communication module, connect the local computer monitoring system.
