STP
Shielded twisted pair
Describes a cable with an outer screen, without defining the nature of the screen any more closely. 屏蔽双绞线
描述了一种电缆的外屏幕，没有任何更紧密地定义了屏幕的性质。
S/STP
Screened/shielded twisted pair (wires are individually screened)
This identification refers to a cable with a screen for each of the two wires as well as an outer shield. 屏蔽/屏蔽双绞线（导线单独屏蔽）
该识别指的是电缆与每个两条线的屏幕以及外部屏蔽。
ITP
Industrial Twisted-Pair
The structure is similar to that of S/STP, but, in contrast to S/STP, it has only one pair of conductors. 工业双绞线
该结构类似于S / STP的，但是，与此相反的S / STP，它只有一对导线。

Start-up behavior of the Bus Coupler总线耦合器的启动行为
Start-up Behavior of the Bus Coupler总线耦合器的启动行为
Immediately after being switched on, the Bus Coupler checks, in the course of a self test, all the functions of its components and the communication on the K-Bus/E-Bus. The red I/O LED blinks while this is happening After completion of the self-test, the Bus Coupler starts to test the attached Bus Terminals (the Bus Terminal Test), and reads in the configuration. The Bus Terminal configuration is used to generate an internal structure list, which is not accessible from outside. In case of an error, the Bus Coupler enters the STOP state. Once the start-up has completed without error, the Bus Coupler enters the fieldbus start state.
