Introduction
This application note describes how to set
up a PROFIBUS system between a Danfoss
Drives FC 300 frequency converter and S7
PLC 315-2 from Siemens.
It is assumed that you are already familiar
with the Simatic S7 system.
Only the steps which are required in order
to establish communication between the FC
300 Profibus and the Simatic S7-315-2 DP
PLC are shown.
NOTE!:
The examples do not describe all the
functions needed for a real application, for
example error handling.
System description
The drawing shows the system in this
application note.
On the PROFIBUS network the stations are
programmed in the following way:
S7 PLC 315-2 DP: Address number 1.
FC 300: Address number 5 PPO Type 2
Module consistent.

Configuring the Profibus network
www.infoPLC.net
Start the SIMATIC Manager and create a
new project.
Open Hardware configuration in S7 Manager
to configure the system.

In order to configure a PROFIBUS system,
the configuration tool needs a GSD file for
each type of slave on the network. The
GSD file is a PROFIBUS DP "standard" text
file containing the necessary communications setup data for a slave.
Download the necessary GSD files at
http://www.danfoss.com/BusinessAreas/
DrivesSolutions
The first step in configuration of the
PROFIBUS Master is to import the GSD file in
the configuration tool. The steps outlined
below show how to add a new GSD file to
the Simatic Manager software tool. For
each drive series, a GSD file is typically
imported once only, following the initial
installation of the software tool.
Using the browser for the GSD file, choose
to install the needed GSD files. Both the
GSD file and a bitmap for the device will be
imported into the Hardware catalogue.

The GSD file is now imported and will be
accessible via the following path in the
Hardware catalogue.
Note that the GSD revision should display a
revision higher than 2.00.
Insert a Profibus network and add a
PROFIBUS Master system. Setup the
Profibus network to a baud rate from 9.6
kbaud to 12 Mbaud.
Select FC 300 from the Hardware catalogue
and drag and drop it to the PROFIBUS
network.
A window for the address of the FC 300
now appears. Select the address from the
scroll-down list. Note that this address
setting must match the address setting in
par. 9-18 Node address.
