Brief description of PROFIBUS
Today, PROFIBUS is the most commonly used fieldbus system. Because it comes with the
widest range of various field devices, PROFIBUS is occasionally prioritised over more
modern bus systems. Due to the low bandwidth and synchronisation mechanisms,
PROFIBUS is only provided as logic bus within "PC-based Automation".
We recommend to use PROFIBUS for the following applications:
Control of system parts that have already been automated with PROFIBUS and another
control system.
Use of field devices that are not available for other bus systems (e.g. CANopen or
EtherCAT).
Combination of PROFIBUS as logic bus with CANopen as motion bus
Tip!
Detailed information on PROFIBUS can be found on the internet page of the
PROFIBUS user organisation:
Note!
In the Lenze control system, only the PROFIBUS master functionality (logic bus)
is supported.
