Research on an Automation Network for CSP Product Line

There are two developing technologies for automation networks designed by SMS Demag and applied to CSP in iron and steel plants, and currently a remote I/O topology for automation network via Internet can solve many of the problems of CSP’s installation, debugging and maintenance on site. This informs us that hierarchical control theory of large scale systems is no longer adapted to the development of network technology. Therefore, the CSP automation network of caster and mill, system management, time synchronization, reflective memory, field bus, remote access, VPN gateway, single port, and security features are analyzed in this paper. Either by adding HMI and remote access to the traditional hierarchical control theory of large scale systems or treating it as an independent part without the traditional hierarchical control theory, this problem is solved in our work. We conclude that HMI and remote access in automation networks have independent and integrated functions and cannot be divided into L0-to-L4 for the metallurgical automation system.
