Advantages of SCADA:
- The data can be displayed in a variety of formats based on the needs of the user.
- Real data simulations can be obtained with the assistance of operators.
- It provides an interface to connect thousands of sensors across the wide region for various monitoring and controlling operations.
- The system is capable of storing large amounts of data.
- Real data simulations can be obtained with the assistance of operators.
- Many types of data can be gathered from RTUs connected with the master unit.
- Data can be monitored from anywhere, not just the local site, thanks to advanced protocols and application software.
- It is fast in obtaining a response.
- The SCADA system incorporates unit redundancy to provide a backup in the event of faults or failures. This strengthens the system.
Disadvantages of SCADA:
- Installation costs are higher.
- Because the system is complex, skilled operators, analysts, and programmers are required to maintain the SCADA system.
- In terms of hardware units and dependent modules, the PLC-based SCADA system is complex.
- The system increases unemployment rates.
- The system allows for the use of restricted software and hardware.
