What are the most common misconceptions about DCS applications in different industries?

1 DCS is only for large-scale plants

One of the most prevalent misconceptions about DCS is that it is only suitable for large-scale plants with hundreds or thousands of control loops. This is not true. DCS can also be used for smaller or medium-sized plants with fewer control loops, as long as they require high reliability, availability, and performance. DCS can offer many advantages over PLCs (programmable logic controllers) or SCADA (supervisory control and data acquisition) systems, such as integrated process control, advanced diagnostics, data management, and operator interface.

2 DCS is too expensive and complex

Another common misconception about DCS is that it is too expensive and complex to install and maintain. This is not true either. DCS can actually reduce the total cost of ownership and increase the return on investment by improving the efficiency, quality, and safety of the processes. DCS can also simplify the engineering and maintenance tasks by providing modular and scalable architecture, standardized and reusable components, and centralized and remote management. Moreover, DCS can leverage the latest technologies and standards, such as Ethernet, wireless, cloud, and IoT, to enhance the connectivity and interoperability of the system.

3 DCS is only for continuous processes

A third misconception about DCS is that it is only for continuous processes, such as oil and gas, chemical, or power generation. This is not true either. DCS can also handle discrete or batch processes, such as pharmaceutical, food and beverage, or automotive. DCS can support different types of control strategies, such as sequential, logic, or PID (proportional-integral-derivative), and different modes of operation, such as manual, automatic, or hybrid. DCS can also integrate with other systems, such as MES (manufacturing execution system), ERP (enterprise resource planning), or LIMS (laboratory information management system), to optimize the production and quality.

4 DCS is only for old-fashioned industries

A fourth misconception about DCS is that it is only for old-fashioned industries that have not adopted the latest trends and innovations. This is not true either. DCS can also be used for modern and emerging industries, such as biotechnology, renewable energy, or smart manufacturing. DCS can enable the digital transformation and the adoption of Industry 4.0 concepts, such as smart sensors, big data analytics, artificial intelligence, or cyber-physical systems. DCS can also facilitate the collaboration and communication between different stakeholders, such as operators, engineers, managers, or customers.

5 DCS is not secure or compliant

A fifth misconception about DCS is that it is not secure or compliant with the regulations and standards of the industries. This is not true either. DCS can provide high levels of security and compliance by implementing various measures, such as encryption, authentication, authorization, firewall, antivirus, backup, or audit. DCS can also comply with the specific requirements and protocols of the industries, such as GMP (good manufacturing practice), ISA-88 (batch control), or IEC 61511 (functional safety).

6 DCS is not flexible or adaptable

A sixth misconception about DCS is that it is not flexible or adaptable to the changing needs and demands of the industries. This is not true either. DCS can provide high levels of flexibility and adaptability by allowing the customization and configuration of the system according to the specific characteristics and objectives of the processes. DCS can also support the evolution and expansion of the system by adding or replacing modules, devices, or software without affecting the existing functionality or performance. DCS can also cope with the uncertainty and variability of the processes by applying adaptive or predictive control techniques.
