Fieldbus communication
8 .2 Configuration, planning
Before commissioning, the bus module must be config-
ured for data exchange with the fieldbus system using
an engineering tool or BCSoft.
o do so, fieldbus communication must be enabled on
the control unit with connected bus module BCM and
the code switches on the BCM set, see also page 106
(Fieldbus communication).
8 .2 .1 Device master data file (GSD), electronic data
sheet (EDS)
The technical properties of a device are described by
the manufacturer for PROFIBUS and PROFINET in a
device master data file (GSD file) or for EtherNet/IP
in an electronic data sheet (EDS). The GSD/EDS file
is required to integrate the device (BCU) in the con-
figuration of the PLC. The GSD/EDS file contains the
device image, the communications properties and all
fault messages from the device in text form which are
important for configuring the PROFINET network and
the data exchange. Modules defined in the GSD/EDS
file may be selected for configuration to integrate the
device. The GSD/EDS file for the bus module can be
obtained from www.docuthek.com. The steps required
to integrate the file are described in the instructions for
the engineering tool for your automation system.
