The steel industry is the environment where the most complex SCADA solutions can be applied, starting with the field area (where the data is collected), the acquisition area (programmable automata), the supervision and control area (Human Machine Interface), the work area of decisions (mathematical models) and ending with resource planning and management (ERP).
The previously specified areas are divided into three levels of automation such as:
-Level 0: field area;
-Level 1: PLC + HMI;
-Level 2: Decision-making area (implementation of mathematical models);
-Level 3: resource planning and management (ERP).
