What do you need for communication via PROFIBUS?

Check the communication settings using the following table. If you answer "Yes" to the
questions, you have correctly set the communication settings and can control the inverter via
the fieldbus.
Questions
Is the inverter correctly
connected to the PROFIBUS?
Have you configured the
communication between the
inverter and the higher-level
controller?
Do the addresses in the inverter
and the higher-level controller
match?
Is the same telegram set in the
higher-level controller and in the
inverter?
Are the signals that the inverter
and the controller exchange via
PROFIBUS correctly
interconnected?
