Abstract: Process control system is a kind of management and control system used in manufacturing enterprise shop floor. It connects the upper planning management system and the lower industrial control system, and optimizes the management of the entire production process through information transfer. In order to implement process control system in iron and steel enterprises, it’s necessary to design reasonable hardware and software architecture, and carry out appropriate system integration according to the production characteristics of process industry. The system plays an important role as the information center of iron and steel enterprises. The network architecture and software architecture of process control system in silicon steel department were introduced in this paper, of which the system integration technology was also analyzed and studied. 

Key words: process control system, system architecture, system integration, enterprise informatization, intelligent manufacturing
