2.4 GSD Files
Supported baud rates are listed in the GSD file (see below). After power-on or PROFIBUS time-
out a baud rate search is active to detect the current transfer speed on the bus. It is not neces-
sary to set the baud rate manually.
If the transfer speed is changed during operation the baud rate search will not be started by
the device. A new power-up or a manual interruption of the PROFIBUS communication is
required to activate the baud rate search in this case.
A “PROFIBUS GSD ZIP” file (e.g. GSD-31777815.zip) including both all KROHNE GSD files and
additional data files can be downloaded from the KROHNE homepage http://www.krohne.com
or contact “KROHNE Marketing”. The GSD file contains information that will be needed for
project planning of the PROFIBUS DP communication network. The relevant data files (e.g.
MFC300_n.bmp; MFC300_n.dib) must be loaded into the bus configuration system/master sys-
tem before start-up of the bus system.
The MFC300 PROFIBUS RS-485 Interface is according to the PROFIBUS PA Profile V 3.01. The
device supports two Ident-No:
• Ident-No. “4510hex” belongs to the GSD file KR014510.GSD and includes the complete func-
tionality concerning the cyclic data exchange of the coriolis mass flow meter MFC300.
• The application of the manufacturer independent Ident-No. “9742hex” (GSD file
“PA039742.GSD”) provides interchangeability of devices, i.e. an exchange of coriolis mass
flow meters of different vendors.
Please follow the instructions in the manual of the host supplier when installing the GSD File
you need and the additional files (MFC300_n.bmp and MFC300_n.dib) into the PLC. If separated
by the bus configuration system the device entry of the MFC300 PROFIBUS RS-485 Interface
with PA Profile 3.01 will be located within the slave family PROFIBUS PA.
