现场总线技术概念 1)现场总线是工厂底层连接现场设备的数字化工业控制网络。现场设备是指车间生产现场安装的自动化仪器仪表,如传感器、变送器及执行机构、驱动装置等;“工厂底层”一词来自工厂自动化网络分层的概念。在工厂自动化系统及信息集成系统中,由于来自不同场合的信息其数量、用途、使用频度不尽相同,工厂自动化信息及通信网络分管理层、车间监控层和现场设备层。
Fieldbus Technology Concepts 1) Fieldbus is a digital industrial control network that connects field devices to the bottom of the plant. On-site equipment refers to the automated instrumentation installed in the workshop production site, such as sensors, transmitters and actuators, drives, etc .; “factory floor” comes from the concept of factory automation network layering. In the factory automation system and information integration system, the quantity, use, and frequency of use of information from different occasions are different. The factory automation information and communication network is divided into management layer, workshop monitoring layer and field device layer.
