Solutions

HollySys provided a comprehensive solution integrating SCADA and PLC. The upper computer monitoring platform features redundant configuration with 2 engineering stations and 5 operator stations. A total of 67 PLCs were supplied: 11 redundant LK210 systems for pump stations, filter pools, ozone, and dewatering processes, and 56 single LK205 systems for filter sub-stations and standalone equipment.

Results

With a daily water supply capacity of 1.5 million tons, this is the largest water plant project using domestic PLCs. The solution effectively handles large-scale point counts and complex network systems. All module boards are coated with a conformal layer for protection against moisture, salt fog, and mold. Customer feedback has been positive, noting stable equipment operation.
