According to the caster control requirements, the design principle of electric control is to be advanced and applied, highly automatic and reliable. Basic automation system consists of electricity, instrument, PLC and operation station control system. Site data collection, process circuit control and equipment sequence control are carried out via basic automation system.The composing of automation system is a design philosophy to make instrument, electricity and automation to be integrative, which is called Three Electricity. Measuring site instruments, limit switch, etc to collect diversified data of producing and equipments, process circuit and electric equipment sequence control, monitoring running state of producing process and equipment, operation coaching, etc are carried out via integrative automation system.Computer system consists of PLC control station and computer operation station. PLC control station adopts SIEMENS S7-300 series control system, which consists of common PLC and strand PLC control station. Common PLC and strand PLC have relatively independent data collection, processing circuit control and electric equipment sequence control. The stations are connected in between via MPI net.
