Commissioning of PROFIBUS
Detailed commissioning steps
6.2 Detailed commissioning steps
The individual commissioning steps are described in the following sections.
Follow the instructions step by step to commission your system.
6.2.1 Planning the bus topology
Before you start to set up a PROFIBUS network, first create a plan of your network.

How to plan the bus topology for your configuration:
1. Create an overview screen of the planned PROFIBUS network with all field devices
to be implemented.
2. Start with the industrial PC (master).
3. Add the other field devices (slaves) below.
6.2.2 Installing field devices
For the installation of a field device, follow the mounting instructions for the respective
device.
Activation of the bus terminating resistor
The PROFIBUS network must be terminated at the first and last station. The bus
terminating resistor is integrated in the bus connector and is activated by a switch.

More detailed information about how to work with the Lenze engineering tools
can be found in the corresponding manuals and online helps.

Note!
Observe the connection between the bus cable length and baud rate.
Baud rate / bus cable length


Note!
If you want to disconnect individual bus stations, ensure that the bus
terminators at the cable ends remain active.
The bus termination is not active anymore if e.g. in the event of service the plug
has been removed or the module supply has been switched off.
