DTM versus GSD File
The language used in the GSD file is indicated by the last letter of the file
extension, *.GS?:
Default = GSD
English = GSE
German = GSG
Italian = GSI
Portuguese = GSP
Spanish = GSS
The GSD files are prepared individually by the vendor for each type of device,
according to a fixed format. Some parameters are mandatory, some have a
default value and some are optional. The device data base file is divided into
three parts:
• General specifications
This section contains the vendor name, the device name, hardware- and soft-
ware release versions, device type and identification number, protocol specifi-
cation and supported baud rates.
• DP master-related specifications
This section contains all parameters which only apply to DP master devices
(e.g. maximum memory size for the master parameter set, maximum number
of entries in the list of active devices, or the maximum number of slaves the
master can handle).
• DP slave-related specifications
This section contains all specification related to slaves (e.g. minimum time
between two slave poll cycles, specification of the inputs and outputs, and
consistency of the I/O data).
For PROFIBUS DP-V1 devices this section also specifies what services for
PROFIBUS DP-V1 are supported.
When comparing the two configuration technologies, a GSD file only provides
information on the device characteristics and configuration options. It has no
GUI of its own, nor can it connect to the device itself. A GSD file always
requires a separate configurator program to interpret the data. In the FDT/
DTM concept all these device related functions are included in the DTM. The
DTM can be executed from any program, which provides FDT interfaces.
Sending PROFIBUS DP-V1 commands to a device from the configuration tool
is only possible using DTM technology. The GSD file does not provide this
means.
