Advantages of SCADA:

  1. The data can be displayed in a variety of formats based on the needs of the user.
  2. Real data simulations can be obtained with the assistance of operators.
  3. It is fast in obtaining a response.
  4. It provides an interface to connect thousands of sensors across the wide region for various monitoring and controlling operations.
  5. The system is capable of storing large amounts of data.
  6. The SCADA system incorporates unit redundancy to provide a backup in the event of faults or failures. This strengthens the system.
  7. Data can be monitored from anywhere, not just the local site, thanks to advanced protocols and application software.
  8. Many types of data can be gathered from RTUs connected with the master unit.
  9. Real data simulations can be obtained with the assistance of operators.

Disadvantages of SCADA:

  1. The system allows for the use of restricted software and hardware.
  2. In terms of hardware units and dependent modules, the PLC-based SCADA system is complex.
  3. The system increases unemployment rates.
  4. Installation costs are higher.
  5. Because the system is complex, skilled operators, analysts, and programmers are required to maintain the SCADA system.
