The document discusses developing a SCADA system based on the open-source scientific computing software Scilab. It introduces SCADA systems and their typical architecture. To address the limited computing abilities of traditional SCADA, the document proposes using Scilab which provides toolboxes for control and optimization. It describes designing a SCADA system based on Scilab and realizing data acquisition with Scilab through interfaces like OPC, Modbus, and industrial Ethernet. Applications of the Scilab-based SCADA system in a water enterprise are presented as a case study.
