2.3 Shielding philosophy
To achieve the highest possible noise immunity and resistance against other EMI
related disturbances the bus and power supply cables shall always be shielded.
The screen should be connected to ground on both ends of the cable. In certain cases
compensation current might flow over the screen. Therefore a potential
compensation wire is recommended.
2.4 GSD-files
PROFIBUS Gateways can be configured and parameterized corresponding to the
requirements of the user. When the system is started, the PROFIBUS devices are set
and configured in DDLM_Set_Prm mode, i.e. the application class set by means of the
GSD file in the configuration tool and the operating parameters are transferred to the
respective slave.
Available GSD files can be downloaded from
www.leinelinde.com.

Note:
GSD file ll__0680 is supported only for compatibility with old Leine & Linde
Profibus gateway, and is not recommended for new customers.
When configuring the gateways two device classes (Class 1 or Class 2) can be selected
as described in chapter 4. Selectable parameters and functionality of the device
depend on the selected encoder class. This data, saved in the PROFIBUS master is
transferred once to the gateway when the system is powered on. If the gateway has
been started with one GSD file and a new GSD file with a different ID-number shall be
used, the gateway needs to be restarted before it can use the new GSD file.
After the configuration and parameter data have been received, the gateway enters
normal operation with cyclic data transfer i.e. "DDLM_Data_Exchange mode".
Installation of GSD-files:
1.
Select and save the GSD file for the respective device from our homepage
www.leinelinde.com
and then copy the *.gsd file into the respective directory
of the PROFIBUS configuration tool.
2.
Select the bitmap file of the respective device and copy the *.bmp file into the
respective directory of the PROFIBUS configuration tool.
3.
Update the GSD files (SCAN).
