For example, Smar’s 302 series fieldbus products can integrate their fieldbus functions in the DCS system network layer The fieldbus is integrated in parallel with the DCS system through a gateway – the fieldbus and DCS can also be bridged through a gateway to achieve parallel integration. For example, SUPCON’s fieldbus system utilizes a HART protocol bridge to connect the system operation station and field instruments, thereby achieving

communication between the fieldbus device management system operation station and the HART protocol field instruments.

The focus of DCS has always been on control, with the keyword ‘decentralized’. However, modern development focuses more on comprehensive management of the entire system information, and in the future, “integration” will become its key word, moving towards the direction of comprehensive automation of control system

operation systems, planning systems, and management systems. The implementation of real-time control and optimization control from the lowest level will rise to production scheduling, business management, and even strategic decision-making at the highest level, forming a flexible and highly automated integrated control system.

The system architecture is evolving towards FCS. From a purely technical perspective, there are three ways to integrate fieldbus into DCS at present: ① Integration of fieldbus on DCS system I/O bus – hanging on DCS I/O bus through a fieldbus interface card, making the information from the fieldbus seen by the DCS controller feel like it comes from a traditional DCS device card. For example, the DeltaV system launched by Fisher Rosemount adopts this integration solution

The integration of fieldbus in the network layer of DCS system refers to the integration of fieldbus system on a higher level network of DCS. This integration method does not require changes to the DCS control station and has little impact on the original system. For example, Smar’s 302 series fieldbus products can integrate their fieldbus functions in the DCS system network layer The fieldbus is integrated in parallel with the DCS system through a gateway – the fieldbus and DCS can also be bridged through a gateway to achieve parallel integration
