PROFINET is the open Industrial Ethernet standard of the PNO (PROFIBUS User Organization). Internationally established IT standards are used for communication.
PROFINET是由PNO（PROFIBUS用户组织）针对开放式工业以太网标准。在国际上建立的IT标准用于通信。
PROFINET IO describes the data exchange between controllers and field devices and can be used in standard Ethernet networks. Commercial switches are used for networking purposes. Linking to any PROFINET controller takes place via the GSDML basic device file.
PROFINET IO描述控制器和现场设备之间的数据交换，并且可以在标准的以太网网络中使用。商用交换机是用于联网的目的。链接到任何PROFINET控制器通过GSDML基本的设备文件发生。
The BK9053 Bus Coupler connects PROFINET with the modular, extendable electronic terminal blocks. One unit consists of one Bus Coupler, any number from 1 to 64 terminals (255 with K-Bus extension) and one end terminal.
该BK9053总线耦合器具有模块化，可扩展的电子接线端子连接PROFINET。一个节点由一个总线耦合器，任意数量从1到64的终端（255使用K总线扩展）和一个末端。
The Bus Couplers recognize the terminals to which they are connected, and perform the assignment of the inputs and outputs to the words of the process image automatically.
该总线耦合器识别终端它们所连接，并执行过程映像的自动词的输入和输出的分配。
