PLC vs. SCADA: Understanding the Major Differences

 

PLC can be defined as a digital computer used in industrial automation and control systems specially designed to carry out control functions and automate machinery. SCADA on the other hand, is a system used for the supervisory control and real-time data acquisition in large-scale industrial processes and systems that works towards integrating hardware and software components to collect, monitor and control data from various devices.

 

Making the right choice for your industrial automation requirements can be aided by understanding the distinctions between SCADA and PLC systems. Therefore, to gain a better understanding of the two topics for the same benefit of your industrial automation, check out the Top PLC SCADA Training in Noida.

Differences Between PLC and SCADA

1.    Functions:

·         PLC - It is responsible for making judgments, operating outputs, and carrying out control logic based on input signals to control machines or processes.

·         SCADA - It is given the responsibility of collecting and analyzing real-time information via different devices and sensors, presenting it in a graphical interface, and allowing the operators to control and manage the process distantly.

2.    Monitoring and Controlling:

·         PLC - Primarily focused on Control, PLC is responsible for executing pre-programmed control algorithms, processing input signals, and generating output signals so as to control the behaviour of machines or processes.

·         SCADA - Primarily focusing on Monitoring, PLC is responsible for gathering data through different sources like PLCs, sensors, etc. and further providing a visual representation of the entire procedure.

3.    Flexibility and System Architecture:

·         PLC - PLCs have been developed to be flexible and dispersed. A network of linked PLCs can manage a complicated system. Each PLC may control a particular area of the machinery or process while interacting with other PLCs to plan out actions.

·         SCADA - SCADAs tend to be flexible and located centrally. They are developed by means of a client-server architecture, wherein a single server communicates with multiple external devices. Also, they are capable of management of complex systems and connecting the same with several PLCs.

4.    Data Analysis and Reporting

·         PLC - Primarily focused on real-time control, PLCs are known for providing limited data analysis features. They may generate the basic reports or logs that are in relation to the system performance and alarms. 

·         SCADA - SCADA is known for offering advanced data analysis and reporting capabilities. They have the ability to analyze historical trends, generate reports, and provide insights into system performance and efficiency.

Conclusion

While PLC and SCADA features may coexist, their core objectives are where they differ most. In contrast to SCADA systems, which are focused on monitoring, data collecting, and visualization, PLCs are primarily utilized for control and automation. They come together to provide a potent system for industrial automation and control.
