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).
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.
The following table shows the differences between the three modes:
following Functions are available
Transmission of AS-i input and
outut data
AS-i circuit can be configured
locally on the gateway
Putting into Operation without addi-
tional parameterization of the Profi-
bus master
Working with a standard I/O-config-
uration on Profibus-DP
Detection of AS-i errors via DP-
diagnosis
Transmission of AS-i parameters to
the gateway while the system is
running (e.g. switching of the mea-
surement range of sensors)
Configuring and parameterizing the
AS-i circuit by the DP-master
Reading and Writing AS-i Control
programs via Profibus-DP
AS-i Transmission of user flags for
the AS-i Control program via Profi-
bus DP
Adjust the size of the I/O windows
to the actual extension of the AS-i
circuit
Transmission of additional AS-i
commands and advanced diagnosis
Subject to reasonable modifications due to technical advances.
