Operation
5.1 General
The plugged-in PROFIBUS
®
module make the PROFIBUS
®
pump
a device with slave functionality in conformity with DP-V0. User
data is then transmitted cyclically.
5.2 GSDML File
Use the GSDML file to configure the master. It describes all fea‐
tures of the pump in PROFIBUS
®
mode (keywords, diagnosis,
modules, slots). The GSDML file can be downloaded from the
ProMinent website
www.prominent.com. The file name is clearly
indicated:
GSDML-V2.2-Hilscher-NL 51N-
DPL-20170316-113214.xml
5.3 Description of the data objects
The initial parameters must be transferred from the
master so that the pump can participate in cyclic
data transfer. Only standard parameterisation is
needed for this – there are no application-specific
parameters.
Please note: Data is stored according to the "Big-
Endian" principle! This means that the byte with
the highest value bits is stored first at the memory
location with the lowest address. For an example
based on “Status” refer to .
The pump status is stored as UINT32 type at the offset addresses
+0 to +3. Bytes are stored in this sequence:
Name
Type
Offset
Byte
Bits
Status
UINT32
+0
0
24 ... 31
+1

16 ... 23
