Abstract: Reviewing briefly the status of automation and process flow in China's cement businesses and combining them with the 3-level ERP/MES/PCS integrated automation architecture that is adaptable to normal industries, a 2-level integrated automation architecture is proposed to integrate management with control function for simplification, of which the two levels are named basic process control and operation optimization. Supported by the advantages of Industrial^IT, ERP and MES, the technologies owned by these businesses are integrated systematically with some existing commercial hardwares/softwares and, eventually, a concrete scheme of integrated automation system is proposed to adapt to the characteristics of those small/medium-scale cement businesses. Practical applications have verified its applicability and validity.
