Commissioning Proline Promass 83 PROFIBUS DP/PA
86 Endress+Hauser
6.6 PROFIBUS system integration
6.6.1 Device master file (GSD file)
For PROFIBUS network configuration, the device master file (GSD file) is needed for every bus user
(PROFIBUS slave). The GSD file contains a description of the properties of a PROFIBUS device, such
as supported data transmission rate and number of input and output data.
Before configuration takes place, a decision should be made as to which GSD file should be used to
operate Promass 83 in the PROFIBUS DP master system.
Promass 83 supports the following GSD files:
• Promass 83 GSD file (manufacturer-specific GSD file):
Use this GSD file to access the complete functionality of Promass 83. In this way, device-specific
measured variables and functionalities are thus completely available in the PROFIBUS master
system. An overview of the modules available (input and output data) can be found on this pages:
PROFIBUS DP → Page 90,
PROFIBUS PA → Page 103.
• Profile GSD file:
The function scope of the profile GSD is defined by the PROFIBUS Profile Specification 3.0. The
function scope is restricted compared to the manufacturer-specific GSD. However, similar devices
from different manufacturers can be interchanged with the profile GSD without the need to
reconfigure (interchangeability).
• Promass 63 GSD file:
Promass 63 with Profile Version 2.0 is the precursor to Promass 83. If Promass 63 is already being
operated in the system and if the device has to be replaced, Promass 83 can be used as a
replacement device without having to reconfigure the PROFIBUS DP network. Further
information → Page 89.
Selecting the GSD file in the measuring device
Depending on which GSD file is used in the PROFIBUS master system, the corresponding GSD file
has to be configured in the device by means of the SELECTION GSD function.

The following modules are supported with the Profile GSD:
“AI Flow” module → Analog Input function block 1 / output variable “mass flow”
“AI Density” module → Analog Input function block 2 / output variable “density”
“AI Temperature” module → Analog Input function block 3 / output variable “temperature”
“Totalizer” module → Totalizer function block / output variable “mass flow”
