DCS工业PC化：由IPC组成DCS已成为一大趋势，PC作为DCS的操作站或节点机已很普遍，PC-PLC、PC-STD、PC-NC等就是PC-DCS先驱，IPC成为DCS的硬件平台。57C328DCS专业化：DCS为更适合各相应领域的应用，就要进一步了解相应专业的工艺和应用要求，以逐步形成如核电DCS，变电站DCS、玻璃DCS、水泥DCS等。
发展方向
DCS发展至今已相当成熟和实用，毫无疑问，它仍是当前工业自动化系统应用及选型的主流，不会随着现场总线技术的出现而立即退出现场过程控制的舞台。面对挑战，DCS将沿着以下趋势继续向前发展：
(1)向综合化方向发展：标准化数据通信链路和通信网络的发展，将各种单(多)回路调节器、PLC、工业PC、NC等工控设备构成大系统，以满足工厂自动化要求，并适应开放式的大趋势。
(2)57C328向智能化方向发展：数据库系统、推理机能等的发展，尤其是知识库系统(KBS)和专家系统(ES)的应用，如自学习控制、远距离诊断、自寻优等，人工智能会在DCS各级实现。与FF现场总线类似，以微处理器为基础的智能设备如智能I/O、PID控制器、传感器、变送器、执行器、人机接口、PLC相继出现。
Poor interoperability. Although analog instruments have unified 4-20mA signal standards, most technical parameters are still determined by manufacturers, resulting in the inability to exchange instruments of different brands. Therefore, it leads to users relying on manufacturers, unable to use the most cost-effective supporting instruments, and even a situation where individual manufacturers monopolize the market.
DCS industrial PCization: The composition of DCS by IPC has become a major trend, and PC has become a common operating station or node machine for DCS. PC-PLC, PC-STD, PC-NC, etc. are pioneers of PC-DCS, and IPC has become the hardware platform for DCS.
DCS specialization: In order for DCS to be more suitable for applications in various corresponding fields, it is necessary to further understand the process and application requirements of the corresponding profession, in order to gradually form DCS such as nuclear power DCS, substation DCS, glass DCS, cement DCS, etc.
Development towards comprehensiveness: The development of standardized data communication links and communication networks, combining various single (multi) loop regulators, PLCs, industrial PCs, NC and other industrial control equipment into a large system to meet the requirements of factory automation and adapt to the trend of openness.
Developing towards intelligence: The development of database systems, inference capabilities, and more, especially the application of knowledge base systems (KBS) and expert systems (ES), such as self-learning control, remote diagnosis, and self optimization, will be achieved through artificial intelligence at all levels of DCS. Similar to FF fieldbus, intelligent devices based on microprocessors such as intelligent I/O, PID controllers, sensors, transmitters, actuators, human-machine interfaces, and PLCs have emerged one after another.
