6.3 PROFIBUS network setup
To be able to setup the PROFIBUS fieldbus network, the AnyBus NetTool for PROFIBUS is
recommended to use.
6.3.1 AnyBus NetTool for PROFIBUS
Anybus NetTool for Profibus is a configuration tool to create complete Profibus-DP network
configurations. The graphical workbench of NetTool allows the compilation of Profibus network
configurations based on slave GS*-files. By online functionality the Profibus configuration can be
downloaded to the master module and the I/O-data of the connected slaves be monitored and
modified.
The configuration tool includes all necessary software and a hardware interface to configure, manage
and troubleshoot your PROFIBUS network.
• When installed, go to the Help-menu where all necessary information/guidelines for the setup can
be found.
6.3.2 Termination
The end nodes(first and last nodes) in a PROFIBUS network must be terminated to avoid reflections
on the bus line.
• Attach a terminating resistor, equal to 220 ohms, to each end of the data transfer cable. The
resistors are connected across the A- and B-lines(Pin 8 and 3 of the SUB-D connector).
Caution
If you do not use terminating resistors as described, the PROFIBUS cable system will NOT
operate properly
6.3.3 Node settings
All nodes have to be, by hardware, setup according to the configuration defined in the software. The
kind of setting device is varying, depending on which manufacturer used.
