Embedded Microprocessory SCADA System for Supervisory, Control and Data Acquisition in the Process of Purification of Gasses in Ferro-Nickel Factor

In this paper is presented development and implementation of embedded microprocessory SCADA system in factory for production of Ferro-Nickel. In the process of refining the molten metal are released huge amount of hot gasses that should be purified before letting them to the atmosphere. The project is to change old system of rellay logic and separately located indicators and controllers with centralised SCADA system with PLC and HMI interface, to monitor and control the work of gas Scrubbers and venting system. The paper presents SCADA system functionality and the advantages from the new digital over the old analog equipment
