10.1 Device master data (GSD file)
All performance features of the NORD PROFIBUS modules are summarised in a device master data
file. For simple PROFIBUS communication, the structure, content and coding of the device master file
(GSD) are standardised in a readable ASCII text file. The GSD file is an electronic data sheet provided
by the manufacturer of the device. It enables convenient planning of the NORDAC inverter in
combination with devices from various manufacturers. In addition to general information, the GSD file
also contains specifications for communication, which are specific to the manufacturer. These
specifications are structured into three sections:
•
General Data
Details of the manufacturer and the device, software and hardware version
numbers, supported transfer rates etc.
•
Master data
Specific parameter details for the master, upload and download facilities.
•
Slave data
Specific parameter details of the slave, number and type of I/O channels,
diagnostic texts and module details for modular device structures.
The standardised GSD files are available for download free of charge on the homepage of
Getriebebau Nord under
In addition, the GSD file can be found on the documentation
CD (Electronic Product Documentation) which is enclosed with the frequency inverter.
For each of the device series vector CT, vector mc, SK 300E, SK 5xxE, SK 700E and SK 750E a
GSD file is available for the standard components up to 1.5 MBaud as well as a file for the special
versions up to 12 MBaud.
•
up to 1.5 MBaud
NORD_1_5.GSD (module without 24V supply)
•
up to 12 MBaud
NORD_12.GSD (module with 24V supply)
For the decentralised device series SK 2xxE with SK CU4-
… or SK TU4-… technology units and
separate 24V power supply, the following GSD file must be implemented.
•
up to 12 MBaud
NORD0BA8.GSD (SK 2xxE technology unit, incl. DP-V1)
This "new" GSD file differs from the previous "old GSD files by the use of newer modules and
extension of the DPV1 functionality.
The PROFIBUS users´ organisation archives this information for all manufacturers and provides this in
Internet. It can be downloaded under

10.2 Ident number
In order for the PROFIBUS master to uniquely identify the various DP devices, the slaves are labelled
with an ident number which is specific to the manufacturer. On start-up of the PROFIBUS master, the
ident numbers of the connected DP slaves are compared with the ident numbers in the specified
planning data in the planning tool. In order to rule out planning errors and malfunctions, the transfer of
