A modern control system application in metals processing and technological progress

In this article, networks and automation structures, which are used in continuous galvanizing line (CGL), is the last project of Cold Mill Lines in Eregli Iron and Steel Works Co., has researched. Network structure is necessary due to complex structure of continuous lines. Server-client system, producer-consumer system and leader/follower-synchronization system which are used in ODS configurations are explained. Open distributed systems´ features and subsystems, which are constructed on LAN are explained using a model configuration. Subjects such as network transmission speed, communication protocols, transmission capacity, addressing in network, max station number on the network and how it is increased, the total length of transmission, the trouble in the transmission channel, the possibility of building a high reliability network and how the network provides high resistance against noise, etc. are examined. Melsec 10 network, man machine interface systems, PLC, DCS and programming terminals and their effect on system cost, reliability, productivity and expendability are explained.
