Introduction to SCADA systems


Introduction

SCADA (Supervisory Control and Data Acquisition) is a type of industrial control system (ICS). Industrial control systems are computer controlled systems that monitor and control industrial processes that exist in the physical world. SCADA systems historically distinguish themselves from other ICS systems by being large scale processes that can include multiple sites, and large distances. These processes include industrial, infrastructure, and facility-based processes


Field of application

Industrial processes include those of manufacturing, production, power generation, fabrication, and refining, and may run in continuous, batch, repetitive, or discrete modes.
Infrastructure processes may be public or private, and include water treatment and distribution, wastewater collection and treatment, oil and gas pipelines, electrical power transmission and distribution, wind farms, civil defense siren systems, and large communication systems.
Facility processes occur both in public facilities and private ones, including buildings, airports, ships, and space stations. They monitor and control heating, ventilation, and air conditioning systems (HVAC), access, and energy consumption.


Common SCADA system components

A SCADA system usually consists of the following subsystems:

A human–machine interface or HMI: is the apparatus or device which presents processed data to a human operator, and through this, the human operator monitors and controls the process.
A supervisory (computer) system: gather (acquire) data on the process and sending commands (control) to the process.
Remote terminal units (RTUs): connect to sensors in the process, convert sensor signals to digital data and send digital data to the supervisory system.
Programmable logic controller (PLCs): used as field devices because they are more economical, versatile, flexible, and configurable than special-purpose RTUs.
Communication infrastructure: connect the supervisory system to the remote terminal units.
Various process and analytical instrumentation.

IC systems and SCADA system


Introduction

IC systems is a leading companies in the design and implementation of Automation and control systems, It has been contributing and applying control systems in the local market and industry since 2002.
