NAiS AIGT3100B Programmable PLC System

NONFERROUS INDUSTRY:
The integrated process control system is a distributed control system.
The system consists of eight process control subsystems (workshop) for raw material grinding, lime

digestion, dissolution, sedimentation, seed filtration, evaporation, product filtration, and roasting.
Each workshop has an engineering station EWS and 2-3 operator stations OPS.
The data collection, real-time monitoring, data processing and other information transmission of the internal

process parameters of the workshop are realized by the EtherNet/IP control network.
The main production operations of the entire alumina plant are completed by these eight subsystems, each

controlled by a ControlLogix controller.
