SCADA is the system used for observing, controlling and retrieving real-time data of industrial processes. Several industrial organisations use it to automate and reduce manual tasks in their workplace. SCADA is a robust software enabling monitoring of remote equipment using human-machine interfaces.
SCADA was first used in the 1960s to respond to the increasing demand for various industries to discover a cost-effective and fully automated means to control their equipment, particularly over great distances. SCADA is a new method for enterprises worldwide to collect and analyse data in real time.
What is Meant by SCADA?
SCADA (Supervisory Control and Data Acquisition) is software that combines hardware elements and software elements to control and regulate industrial processes. It allows the operators to check the industrial processes locally or at remote sites. Apart from this, the software helps industrial organisations in several ways, including:
- Observing, collecting and managing real-time data
- Maintaining a log file about every event
- Direct interaction with devices and machinery like pumps, sensors, valves, etc., through the human-machine interface.
Supervisory Control and Data Acquisition systems are essential in several industries. It is because they aid in efficiency maintenance and relay system errors to help resolve the issues. The SCADA also helps industrial organisations make smarter decisions based on the available data.
How Does SCADA Work?
The fundamental architecture of SCADA consists of remote terminal units and programmable logic controllers.
PLCs and RTUs are electronic devices that communicate with various objects, including industrial machinery, HMIs, sensors and end devices. They then transport data from those objects to computers utilising SCADA software. The SCADA software analyses, transmits and displays data, enabling operators and other personnel to reach important decisions.
For instance, the SCADA software system can immediately alert an operator if a batch of products has a high rate of faults. To determine the root of the problem, the operator pauses the process and employs an HMI to view the SCADA system information. When the operator checks the data, he discovers that a particular machine is not functioning correctly. Thus, the SCADA helps prevent further product loss by informing the operator of the issues in the devices.
What Are The Features of SCADA?
A few critical features of SCADA are as follows.
- Trending in real-time and in the past
Trend or pattern is an essential SCADA function. Any industrial operation that needs monitoring and documentation frequently requires trends. Mainly trends are critical in the automation industry. The SCADA system can store real-time data from fields, extract past data, and present it graphically.
- Handling of alarms
Alarms are needed to bring the operator’s attention to important features of the plant’s current status. SCADA can perform this work with great precision. For example, it can catch discrepancies in the rate of change for digital readings, variations in digital input/output data, and display previous alarms.
- Production of reports
The report generation is a fantastic feature that SCADA provides. However, first, the user must create a report template they want. Additionally, the user can choose incidents in which the reports will be generated. Furthermore, users can also utilise specific options to create reports manually.
Where is SCADA Used?
Several industries now employ SCADA software to manage industrial processes actively, minimise outages, increase efficiency, and assess past data. It has become the mainstay for various modern-day businesses, including
- Manufacturing industry
- Food and beverage industry
- Oil and gas industry
- Transportation
- Wastewater treatment plants
- Energy and power generation industry.
What Are The Advantages of SCADA?
The Supervisory Control and Data Acquisition has several benefits, including
- Decrease in the workforce necessary to run and monitor equipment in multiple areas.
- Generation of both automatic and manual data. These data can be presented in different formats according to the users’ requirements.
- Remote access of real-time data, patterns, notifications, etc.
- Decrease in the number of device errors by constantly monitoring their statuses.
Apart from the above advantages, SCADA is also beneficial in storing large amounts of data. It is a robust and versatile software that has a quick response time.
Conclusion
SCADA (Supervisory Control and Data Acquisition) combines software and hardware elements that observe, control and regulate industrial processes. It is widely used in the manufacturing, transportation, food and beverage, and automation industries, to mention a few.
The significant advantages of using SCADA software are increasing work efficiency, reducing product losses, and quickly fixing any device errors in the line. The notable features of this system are alarm handling, generating reports and trends, and extracting past data to aid operators in making important decisions.
