Profibus-DP
In this chapter, you learn everything necessary to run the AS-i/PROFIBUS Gateway
in a Profibus-DP network.
For data exchange on Profibus-DP there are three operation modes: the easy mode,
the advanced mode and the professional mode (advanced mode with management
channel).
The following table shows the differences between the three modes:
Hint: If you try to put an AS-i/PROFIBUS Gateway in operation the first
time it is advisable to use the easy mode because it is much easier than
the advanced modes.
following Functions are available
in easy mode
