4、现场总线控制系统（FCS）
FCS正是顺应以上潮流而诞生，它用现场总线这一开放的，具有可互操作的网络将现场各控制器及仪表设备互连，构成现场总线控制系统，同时控制功能彻底下放到现场，降低了安装成本和维护费用。因此，FCS实质是一种开放的、具可互操作性的、彻底分散的分布式控制系统，有望成为21世纪控制系统的主流产品。
三、现场总线及现场总线控制系统
1、现场总线的概念

The system uses the same set of configuration tool software to complete the configuration and debugging of process level, operation level and even fieldbus instruments, and uses the same
a global database.
The scale of the system is highly scalable, and a single-system supports 1 to a maximum of 100 control stations and 100 operating stations. each control
The station can support several thousand I/0 points at most, and the scale of the whole system can be expanded. The hardware of the system control station is encapsulated in an all-metal shell, which can withstand the most
Harsh industrial environment. The device can be installed either in a cabinet or on a wall. System complies with all current EMC standards and is CE marked
