Unplugging a bus connector
You can unplug a bus connector with a looped-through bus cable at any time from the
PROFIBUS DP interface without interrupting data exchange on the bus.
Data traffic error might occur on the bus!
A bus segment must always be terminated at both ends with the terminating resistor. This
is not the case if the last bus connector node is de-energized, for example. Because the
bus connector takes its voltage from the station, this terminating resistor is ineffective.
Please make sure that power is always supplied to stations on which the terminating
resistor is active.

Configuring an Ethernet subnet on the Ethernet interface
Overview
You can connect an Industrial Ethernet to the 8-pin RJ45 X7 socket, see Figure "Overview of
the cable connecting the SIMOTION C to the servo drive (digital connection) - example" in
chapter Overview of wiring diagram (Page 94).
Industrial Ethernet is a communication network with a transmission rate of 10/100 Mbits/s.
Communication between SIMOTION C, the PG/PC (e.g. STEP 7, SIMOTION SCOUT,
SIMATIC NET OPC), and the I/O devices provided for this purpose is supported by the
Ethernet.
A shielded twisted pair cable is used for the networking in this case. For additional
information, refer to the
Manual. This document is supplied in electronic format with SIMOTION SCOUT.
The following connecting cables are recommended:
● SIMATIC NET, Ind. Ethernet TP XP CORD RJ45/RJ45, TP cable assembled with 2 RJ45
● SIMATIC NET, Ind. Ethernet TP CORD RJ45/RJ45, TP cable assembled with 2 RJ45
You can obtain additional information about the different cable systems for Ethernet from
your SIEMENS contact.
Note
A crossover cable should be used for the direct connection of the controller to a PG/PC.
