(SCADA) Supervisory Control and Data Acquisition Could Be Closer Than You Think

SCADA is a system of hardware and software components that enables an organization to analysis and visualization through geospatial view, one-line diagram, smart graphical user interface, and digital dashboards. Some of the key elements of SCADA includes HMI (Human-Machine Interface), communication infrastructure and field devices. Some of the main trends witnessed in SCADA are availability of increased situational awareness with the help of enhanced presentation of data and GUIs; intelligent alarm processing; improvised integration with other business and engineering systems; and enhanced security features. SCADA is intensively used in multiple applications including oil and gas, process industries, distribution and utilities, electric power generation, water and waste control, manufacturing, agriculture/irrigation, transportation systems.
The SCADA system developed provides fault isolation operation, monitoring and controlling functions for the operators and data collection for future analysis. An embedded Ethernet controller is used as RTU to act as converter for human machine interface (HMI) and to interact with digital input and output modules. RTU is the master and digital input and output modules are the slaves. RTU will initiate the transaction with the digital input and output modules. Two proprietary software systems are used are to develop algorithm for the controller and to develop HMI for monitoring and controlling functions for the operator.
Tremendously rising demands for industrial mobility, particularly for remote management in the process industry is anticipated to significantly attract the market growth in coming years. However the market might get adversely impacted by high investment for initial SCADA system integration.
