4.1 Interface selection and mapping files
Precondition The parameterization of PROFIBUS-DP for a SIPROTEC device requires:
• selection of PROFIBUS-DP as system interface,
• selection of a mapping file which fixes the allocation of the data objects of the
SIPROTEC device to the positions in the PROFIBUS-DP messages.
Bus specific parameters have to be defined simultaneously when selecting a mapping
file (ref. to chap. 2.1).
4.1.1 Standard mappings 3-1 to 3-n
A number of standard mappings (standard mapping 3-1 to standard mapping 3-n, n =
device type dependent number of standard mappings) are available for every SIPRO-
TEC device type.
These mappings are different in the data size available via PROFIBUS-DP and offer
a standard pre-allocation of SIPROTEC data objects to positions in the PROFIBUS-
DP message.
Adaption of the
allocation
In adaptation to the concrete installation environment the standard allocation can be
changed (ref. to chap. 4.2):
• removing of data objects from the PROFIBUS-DP message,
• routing of data objects to free message positions,
• scaling of measured values according to the operating values of the primary
equipment.
Note:
The size of the PROFIBUS-DP messages (number of commands, annunciations,
measured values, metered measurands) in output or input direction is exclusively
fixed by the selection of a standard mapping.
The data in the PROFIBUS-DP messages are defined in the bus mapping documen-
tations of the individual SIPROTEC devices (ref. to page 3).
