Application of Scada In IoT Based Industrial Automation

Abstract

SCADA stands for Supervisory Control and Data acquisition which is a process control system that enables a site operator to monitor and control process that is distributed among various remote sites. As such, it is a purely software package that is Positioned on top of hardware to which it is interfaced, in general via Programmable Logic Controllers (PLCs), or other commercial hardware modules. SCADA systems are combination of computers, controllers, instruments; actuators, networks and interfaces that manage the control of automated and allow analysis of those system by data collection and processing. They are used in most industrial processes: e.g. steel making, power generation (conventional and nuclear) and distribution, chemistry, but also in some experimental facilities such as nuclear fusion. The size of such plants ranges from a few 1000 to several 10 thousands input/output (I/O) channels. However, SCADA systems evolve rapidly and are now penetrating the market of plants with a number of I/O channels of several 100 K.
