Rules for laying
PROFIBUS cables must not be twisted, stretched, or compressed.
When installing the indoor bus cable, you should also remember the following boundary

Bus connector
The bus connector is used to connect the PROFIBUS cable to the PROFIBUS DP interfaces
(X8, X9), thus establishing a connection to additional nodes.
The following bus connectors are available:
● Up to 12 Mbits/s, cable outlet 90°
● Up to 12 Mbits/s, canted cable turn
Inserting a bus connector in a module
Proceed as follows to connect the bus connector:
1. Plug the bus connector into the module.
2. Screw the bus connector tightly onto the module.
3. If the bus connector is located at the start or the end of a segment, you must connect the
Make sure that the nodes at which the terminating resistor is located are always supplied
with voltage during startup and operation.
