ABB PPC907BE 3BHE024577R0101 adapted to the needs of large-scale control, function-oriented and object-oriented implementation of the “station” as the basic unit, and its specially designed distributed real-time database is used to manage all the data required by the system distributed in the various stations. The system is divided into stations based on the principle of relative autonomy of functions, and different functions are realised by different stations.

ABB PPC907BE 3BHE024577R0101 system consists of seven kinds of stations: ENG station, OPR station, DPU station, HSR station, LOG station, CAC station, GATEWAY station. Some stations can be set up individually or combined on a single station.LICON DCS products adopt a two-layer network structure, using redundant high-speed data industrial field buses between the I/O and control station (DPU) to complete the data exchange between the I/O and control station. The advantages are high communication rate, high fault tolerance and good reliability;

ABB PPC907BE 3BHE024577R0101 adopts redundant 100M/1000M switched Ethernet structure between DPU and each ENG station, OPR station and HSR station, and the network can automatically diagnose node faults and automatically switch communication network in real time to ensure real-time and reliable data transmission. The product adopts full isolation and full redundancy technology to ensure the isolation of I/O bus, isolation of I/O channel, isolation of I/O channel and field, isolation of digital and analogue circuits inside I/O, isolation of communication power supply, CPU power supply inside I/O, and excitation power supply of field signal;
