Bus connector
The cables must be connected using PROFIBUS bus connectors as these contain the
necessary bus terminating resistors.
Suitable PROFIBUS bus connector: Article No. 6GK1500-0FC10
Figure 10-11 PROFIBUS bus connector
Bus terminating resistor
The bus terminating resistor must be switched on or off depending on its position in the bus,
otherwise the data will not be transmitted properly.
Principle: The terminating resistors must only be switched on at both ends of the bus line;
the resistors must be switched off at all other connectors.
The cable shield must be connected at both ends and over a large surface area.
