SCADA stands for supervisory control and data acquisition.
It is an automated control system in various sectors, including oil and gas, water, energy, and electricity. The SCADA system has a centralized system that monitors and manages whole locations, from industrial facilities to a complex of facilities spread throughout the nation.
A SCADA system uses signals that communicate through channels to provide the user with remote controls of any equipment in a system.
Operation Mechanism of SCADA:
A SCADA system combines hardware and software elements that enable local and remote plant supervision and control. The SCADA also does real-time data analysis, gathering, and processing. Software for HMI makes it easier to communicate with field equipment like pumps, valves, motors, sensors, etc.
The SCADA program also offers the option of logging data for historical use. Programmable logic controllers, often known as PLCs and remote terminal units, are the building blocks of the typical SCADA system.
RTUs and PLCs, as you are aware, are microprocessors that interface and communicate with field devices like valves, pumps, and HMIs. The SCADA computers receive this communication data from the processors, where the software analyses and displays it so that operators may assess and respond to system events.
Evolution
Before SCADA, plant staff had to use selection switches, push buttons, and knobs for analog signals to monitor and manage industrial operations that required workers to stay on-site during manufacturing. Relays and timers were used to help with process monitoring as production expanded and insights became more away from the natural world.
Relays and timers provided some automation, but It was impossible to troubleshoot, and reconfiguring was challenging too. These problems aid in the development of automation and the requirement for progressively more significant industrial operations.
Modern SCADA
Modern SCADA systems have evolved to keep up with new technological developments. With contemporary ITI standards like SQL and web-based applications, they significantly outperform earlier SCADA systems.
The SQL database model and historical data gathering may also be logged and utilized in trending applications to optimize plant operations further and establish mandatory recordkeeping for some industries, as the present SCADA system software is generally accepted.
Essentials of SCADA
There are five essential composing parts of the SCADA system.
-
Human-machine interface or HMI
A human operator may monitor or manage the system using the HMI’s data.
-
Supervisor system
The supervisory system collects the data and communicates instructions or orders to the process.
-
Remote terminal units or RTUs
This is the technique of using networked sensors, translating their analog signals into digital data, and sending that data to a supervisory system so we can store it in a distributed database.
-
Programmable Logic Controllers PLCs
PLCs are employed in the field instead of processed ones since they are far more adaptable and affordable.
-
Communication Infrastructures
The communication infrastructure then provides connectivity to supervisory systems and PLCs and RT use so that the user may control them.
Importance of SCADA in industries
SCADA systems are essential for industrial enterprises to;
- Sustain efficiency
- Communicate system problems to save downtime
- Process data to make more informed decisions
