4. Configuration of the PROFIBUS module

4. Configuration of the PROFIBUS module
Several steps are required in order to produce a functioning PROFIBUS module. Some of
these settings should or must be carried out before the PROFIBUS communication is
activated. This chapter provides an overview of the relevant steps. The exact procedure is
described in the following chapters in more detail.
When planning the PROFIBUS module, the user must make firm decisions. Only then
should the parametrizing of the field bus connection on both sides be made. We recom-
mend that the parametrizing of the slave be undertaken first. Then the master should be
configured. With correct parametrizing the application is ready immediately without com-
munication faults.
As some parameters are not effective until save and reset, we recommend the following
procedure.
1. Setting the bus address in the FCT program in the window Operation Parameters.
2. Parametrizing and commissioning with the FCT. Especially also the setting physical
units.
3. Configuration of the PROFIBUS master.
For correct functioning it is necesary to define the physical units of the processing data
transmitted via the field bus. These can be set via the FCT.
