Using the Fuchs GSD Converter
In order to convert GSD files, proceed as follows:
1. Start the program PFGSDCX.EXE
The following dialog window appears:
2. Select the directory that contains the GSD files intend to convert.
3. Select the GSD files you intend to convert.
Files preceded by a "+" symbol are the result of a previous conversion. These files cannot
be converted again and an error message appears if an attempt is made to do so.
Files beginning with a "-" symbol have not been converted yet and can be converted if
required. Doubleclick to open and view or edit a file.
You can select one or more files for conversion by pressing the [CTRL] or [SHIFT] keys.
4. Select the directory where you intend to store the converted GSD files.
5. Convert the GSD files by clicking the
Process GSD ->
button.
A window opens with information on the finished conversion process.

Information on Watchdog Time (T
WD
)
PROFIBUS devices can activate a mechanism that monitors each time interval in the cyclic
data exchange process (or "user data exchange") to ensure that the PROFIBUS master is still
active. This socalled watchdog time (T
WD
) is measured in the PROFIBUS slave.
If the response monitor is active and the T
WD
since the last cyclic polling process has expired,
the device stops the cyclic data exchange, reverts to its original status (Wait_prm) and secures
the status of the outputs.
The T
WD
time value and the signal for activating the response monitor are transmitted from the
PROFIBUS master to the PROFIBUS slave in the parameter telegram at start-up during the
cyclic data exchange. The T
WD
is generally defined as user-specific and not device-specific,
i.e., it is not included in the GSD file. Lower values are limited by the cycle times.
Note!
The advisory board of the PROFIBUS user organization has agreed not to rescind the
certification of GSD files that are modified using Fuchs GSD converter software.
