The Ethernet-based real-time data communication metwork of SCADA(Supervisory Control And Data Acquisition) system possesses high band width and low error,but results in network congestion,communication delay and data loss when communication traffic is heavy.The IP multicast communication mode is applied to avoid it.IP multicast technology is introduced and its communication mode in SCADA system is discussed.With a communication middleware designed,the message receiving and retransmitting mechanism is established to ensure the real-time and reliable communication.Practice shows its good perfotmance in SCADA system.
