What is SCADA?
wireless scada Supervisory Control and Data Acquisition
SCADA is the acronym for Supervisory Control and Data Acquisition.
SCADA is a computer-based system for gathering and analyzing real-time data to monitor and control equipment that deals with critical and time-sensitive materials or events.
SCADA systems were first used in the 1960s and are now an integral component in virtually all industrial plant and production facilities.
SCADA Systems are widely used in the following:
Oil and Gas
Pipeline monitoring and control
Remote monitoring and control of production, pumping, and storage locations
Offshore platforms and onshore wells
Refineries, petro-chemical stations
Water and Wastewater
Water treatment centers and distribution
Wastewater collection and treatment facilities
Utilities
Electrical power distribution from gas-fired, coal, nuclear
Electrical power transmission and distribution
Agriculture / Irrigation
Manufacturing
Food and Beverage
Pharmaceutical
Telecommunications
Transportation
Wireless SCADA Importance ?
One of the biggest advantages with the system in place is the fact that the top management always has timely and accurate data available to them at any time.
The real time data can be used by them to optimize the operation of a plant or a business process.
The system enables considerable improvement in the efficient running of a plant.
Moreover, it also ensures data safety, another crucial aspect that needs to be considered by businesses today.
When viewed from a company’s perspective, the system is invaluable, with it lessening the operating cost quite significantly.
The efficiency of the system directly translates into higher profits for businesses operating in various different sectors.
Components of SCADA
SCADA systems utilize Distribution Control Systems (DCS), Process Control Systems (PCS), Programmable Logic Controller (PLC) and Remote Terminal Units (RTU)
that perform the majority of local and remote process alarming, monitoring and control. The PLC or RTU are the Main work horses in the industries listed above.
The main Process of these devices includes observing liquid level and gas meter readings, equipment voltage and current, operating pressure and temperature, or other equipment status.
