Industrial automation and control system-SCADA.


    

Industrial control system (ICS) is general term that encompasses several types of control systems used in industrial production, including ‘Supervisory Control And Data Acquisition (SCADA) systems.

ICS’s are typically used in industries such as electrical, water, oil, gas, and data. Based on data received from remote stations, automated or operate driven supervisory commands can be pushed to remote station control devices, which are often referred to as field devices. Field devices control local operations such as opening and closing valves and breakers, collecting data from sensors systems, and monitoring the local environment for alarm conditions. SCADA system is one of those.

SCADA is an industrial automation control system at the core of many modern industries, including:
  • Energy
  • Food and beverage     
  • Manufacturing
  • Oil and gas
  • Power
  • Recycling
  • Transportation
  • Water and waste water, And many more,

SCADA is a system used for remote monitoring and control, it operates with coded signals over communication channels. The control system may be combined with a data acquisition system by adding the use of coded signals over communication channels to acquire information about the status of the remote equipment for display or for recording functions. It is a type of industrial control system (ICS). Industrial control systems are computer-based 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.

In simple, SCADA software works like this, information from sensors or manual inputs are sent to PLCs (programmable logic controllers) or RTUs (remote terminal units), which then send that information to computers with SCADA software. SCADA software analyses and displays the data in order to help operators and other workers to reduce waste and improve efficiency in the manufacturing process.

In all, having and using a SCADA system can in turn save a lot of money and time for the industries.
