Connectors
The cables must be connected via PROFIBUS connectors as they contain the necessary
terminating resistors.
A suitable PROFIBUS connector with a straight cable output is shown below.
Figure 4-13 PROFIBUS connector without PG/PC connection, Article number 6GK1500-0FC10
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.
The terminating resistors for the first and last nodes in a line must be switched on; the
resistors must be switched off at all other connectors.
The cable shield must be connected at both ends over large-surface area contacts.
Note
Connector type
Depending on the connector type, the correct assignment of the connector must be ensured
(IN/OUT) in conjunction with the terminating resistor.
