4.1 Integration of GSD
PROFIBUS PA system requires GSD file which describes the device parameters such as the transmission
rate supported, input, output data, data format and data length.
The GSD files described below are available to RAMC.
You can download the GSD file from
http://www.profibus.com/products/gsd-files/

4.2 Important Device Settings
The tables below show items (parameters) which need special care to ensures a proper working of the
RAMC Profibus type.
Table 4.1 General settings
Item
Settings
Bus address
Set to 0x7E (126) by default unless otherwise specified when ordered
In case of unit change (compared to initial ordering) it is recommended to change the OUT_SCALE parameter
as described in table 4.3 only. Change of the Process Variable needs in addition the changes described in
the tables 4.2 and 4.3.
Table 4.2 Initial settings of Transducer Block
Item
Settings for Volume flow
Settings for Mass flow
Parameter: VOLUME_FLOW_UNITS
Choose unit (initially set to unit specified
when ordered)
Not active 1("Volume flow passivated")
Parameter: MASS_FLOW_UNITS
Not active 1 ("Mass flow passivated")
Choose unit (initially set to unit specified
when ordered)
NOTE
Change of the parameters VOLUME_FLOW_UNITS to MASS_FLOW_UNITS or vice versa needs in
addition the adaptation of the parameter CHANNEL inside the AI block, to make the change effective on
the OUT parameter.
