现在工程师可以选择各种各样的过程工业网络用于将现场仪表和控制器连接起
来。使用开放式网络显著降低了布线成本并可获得更多诊断信息。现在您可以在工厂中安装I/O总线，GE智能平台8000过程I/O系统便可以解决所有实际问题。
GE智能平台 8000过程I/O是一种可以在现场安装的、可代替现场接线箱的I/O系统。它允许将不同类型的现场设备连接到一个网络节点上。各个I／0节点可以连接在一起，构成一个快速、高效和开放的I/O系统。
哪一种总线是标准总线？
目前，这个问题尚未得到肯定答复，所以GE智能平台8000过程I／O允许不同的总线连接到一起。例如，可以通过现场总线(Profibus)或控制网(ControINet)传输HART@数据。这意味着您不必担心在选择总线后购买不到可以与其连接的设备。此外，现有的标准4-20mA设备也可与最新网络连接
。International standard fieldbus, Profibus is the most widely used open fieldbus international standard in the world, divided into FMS, DP and PA
Level 3, DP communication rate can be as high as 12Mb. Profibus is used to connect intelligent devices such as distributed I/0 stations and field bus instruments.
Communication between the process station, operator station and engineering station takes place via the system bus DigiNetS (Industrial Ethernet). user
Different transmission media (RJ45 twisted pair, thin, thick or fiber optic cables and mixed media) and network topology can be selected for the system bus.
Simple layout, due to the use of TCP/IP protocol, the system can also use the public telephone network (dial-up mode) or satellite to achieve ultra-long-distance communication.
Subsystems such as PLC communicate with the Industrial” system through the ModBus protocol interface. The
