With use of modern control systems for industrial processes their performance, transparency and efficiency is improved. Sequential control is one of approaches to control of industrial control system. In paper manufacturing the accuracy and proper fiber intake functioning of individual lines are very important. With waste paper line improvement better quality of fiber intake process was achieved. The control system has to be not only functionally flawless, but also transparent. With improved input table the operation is more transparent and accurate. The sequential control approach was used when redesigning the lines. SCADA system is used for supervision of the process. The results of improvement are better and more accurate operation of the lines, higher energy efficiency by eliminating deflakers from the process, more accurate entry of raw materials and the transparency of the entire process.
