PLC and DCS Comparison in Application in improving plant quality, operations, profitability and reducing costs




To be more efficiently in control system design , you have to know deeply about PLC and DCS comparison in application. We cannot hide behind the truth that DCS we large, expensive and designed with very complex systems considered as a control solution for the batch or continuous process industries. This is why engineers usually squeeze opting for PLCs and HMIs or SCADA to keep the costs down.

Many people don’t realized that integrating independent PLCs, engineers actually focus on making the different type of technology work together rather than improving plant quality, improving operations, improving profitability and reducing costs. Those the changes already made with the PLC and DCS comparison in application today.

When the changes required for the PLC and DCS comparison in application Databases?

PLC and DCS comparison in application system may have all or part of independent and manually coordinated databases such as alarm management, batch/recipe and PLI, historian, fieldbus device management, controller I/O, and asset optimization. Each of mentioned databases must be synchronized for the whole of system to function properly.

PLC and DCS comparison in application is fine by synchronizing the entire database and the result might subtle immediately after initial system development. However, the system becomes unnecessary when the changes made in on-going process because of continuous improvement program. Every time changes conducted in one database, the others usually need to be updated. In instance, when I/O point and control logic added to the system, they always require several changes to the PLC system like adding SCADA element, historian or alarm database. This action leads the engineer to make these changes in each of these databases. This is why PLC and DCS comparison in application can be impractical ways to the entire of the process.


PLC and DCS comparison in application Provides Cost-Friendly through One Database

PLC and DCS comparison in application today developed to allow the plant or industry to immediately implement the entire system with one-based database. The single database operated, designed and configured from the same application. The mechanism provides dramatic cost reductions when using DCS technology collated to the PLC or SCADA especially when it comes to the cost of engineering.

The case today, PLC and DCS comparison in application hardware is not anymore as the subject of the large and expensive equipment. The newer DCS hardware is looks like similar to the PLCs today. The DCS’s software also runs on the same specification PC as PLC. It also uses the same model of networking. That is true opting for the complete features of DCS may ends into the pricey cost. However, engineers already understand to what they need for the plant improvement. So, they can eliminate several features that are unnecessary.

PLC and DCS comparison in application has all-around ability in broad range of application starting from system design, programming, troubleshooting to the system documentation.


Conclusion

PLC and DCS comparison in application has implemented in improving plant quality, improving operations, improving profitability and reducing costs. According the major opinion, DCS is a subject to the expensive system in the industry application. This is not the case today. DCS provides integration to the system through one database that capable to control the continuous or batch applications in the simpler way. DCS can be great solution to help reduce costs and gain better control that finally reducing the return on investment (ROI) payback period.
