PROFIBUS DP Network configuration
Section 1-2
Two types of configuration technology exist:
• Configuration technology based on FDT/DTM technology
• Configuration technology based on GSD-files
FDT/DTM Concept
The FDT/DTM concept specifies the interfaces between the engineering sys-
tems called Field Device Tools (FDT), and the device-specific software com-
ponents called Device Type Managers (DTM).
The FDT/DTM concept separates the device dependent functionality (which is
in the DTM) from the application. It provides separate interfaces for device
configuration, monitoring and maintenance solutions, which before largely
depended on the manufacturer of the application. Because of this concept,
FDT/DTM technology is not limited to PROFIBUS applications. In concept,
any type of network can be configured and accessed, provided the appropri-
ate DTM’s are available.
CX-Profibus is an example of a FDT container application. It is described in
detail in the following sections.
GSD file Technology
The older and most commonly used configuration technology is the based on
GSD files (General Slave Data file). A GSD file is a text file, containing the
characteristic features and configuration options of a device. The device data
base file of each device is loaded in the configurator and downloaded to the
master device.
GSD files are usually supplied with a unit, or can be downloaded from the
Internet, either from the manufacturer's site, or from the GSD library of the
PROFIBUS Nutzer Organisation at http://www.profibus.com.
GSD File Language
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 Section
•
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 Section
•
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 Section
•
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).
