4.1 Integration of GSD
PROFIBUS PA system requires GSD le which describes the device parameters such as the transmission
rate supported, input, output data, data format and data length.
The GSD les described below are available to RAMC.
You can download the GSD le from http://www.probus.com/products/gsd-les/.
Table 4.1 GSD les
GSD le name Ident. Number Comment
PA139700.GSD (AIx1) 0x9700 Prole specic
RY014582.GSD 0x4582 Device specic
4.2 Important Device Settings
The tables below show items (parameters) which need special care to ensures a proper working of the
RAMC Probus type.
Table 4.1 General settings
Item Settings
Bus address Set to 0x7E (126) by default unless otherwise specied 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 ow Settings for Mass ow
Parameter: VOLUME_FLOW_UNITS Choose unit (initially set to unit specied
when ordered)
Not active 1("Volume ow passivated")
Parameter: MASS_FLOW_UNITS Not active 1 ("Mass ow passivated") Choose unit (initially set to unit specied
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.
