TECHNICAL PAPER

Full electrical revamp of a Cooling Bed Area in a record time

Challenge
Project consisted in the upgrade of the cooling bed zone that was managed by a MODICON plc, an RELIANCE AUTOMAX plc was managing the axis controls and other AUTOMAX were managing power modules of the dc drives. Critical point for the customer were the minimum spares present in plant and the impossibility to find new pieces.

Project has began months in advance than the shutdown phase due to the minimum time available for the Christmas shutdown of the plant. Criticity of the project included the activity of placing the new automation system in several networks already present in plant, such as Profibus to the mill control system actually managed by an ABB plc, and MB+ network with the rest of the packing area and level 2 interface that is managed by MODICON plc's.
