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
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.
