The DCS system is a large system, and its controller has strong functions and plays a very important role in the system. The data highway is the key to the system, so the overall investment must be made in one step, and subsequent expansion is difficult. However, the decentralization of FCS functions is relatively thorough, information processing is on-site, and the widespread adoption of digital intelligent on-site devices weakens the function and importance of the controller.
The DCS system is a closed system, and the products of various companies are basically incompatible. The FCS system is an open system, where various products from different manufacturers and brands can be connected to the same fieldbus simultaneously, achieving optimal system integration.

The information of the CS system is all formed by binary or analog signals and must be converted through D/A and A/D. The FCS system completes the conversion of D/A and A/D in a single meter on site, achieving full digital communication, greatly improving accuracy to 0.1%. And the FCS system can incorporate the PID closed-loop control function into on-site equipment, shortening the control cycle, increasing computational speed, and thus improving regulation performance.
DCS can control and monitor the entire process of the process, diagnose, maintain, and configure itself. However, due to its own fatal weakness, its I/O signals use traditional analog signals, making it impossible to remotely diagnose, maintain, and configure on-site instruments (including transmitters, actuators, etc.) on the DCS engineer station. FCS adopts fully digital technology, and digital intelligent field devices send multivariate information, not only single variable information, but also have the function of detecting information errors.
