PROFIBUS-DP Configuration data

SIPROTEC PROFIBUS-DP - Communication profile
C53000-L1840-B001-03
The following settings are only available if a mapping file is selected which supports
an event list (Sequence of events recorder) via PROFIBUS-DP for the SIPROTEC
device.
Further information regarding the properties and accessing the event list via PROFI-
BUS-DP can be found in chapter 2.5.
GlobalSection.DP_EvtLst_ListSize
This parameter determines the number of event list entries on the communication
module (range: 10 to 1000).
If the event list already contains the set number of entries (as e.g. no retrieval by the
PROFIBUS-DP master was carried out) when a new entry arises, then the "First in
First out" principle applies, i.e. the oldest entry is replaced by the new entry and an
overflow flag, which is transmitted to the PROFIBUS-DP master the next time entries
are retrieved, is set.
The default setting value is 500.
Configuration data are needed in the PROFIBUS-DP master for parameterization of
the SIPROTEC devices.
The DDB file/GSD file characterises the SIPROTEC communication module as a
"slave with modular design", i.e. depending on the selected mapping, the number of
input and output data is modified without changing the DDB file/GSD file.
The configuration data to the various devices are contained in the corresponding bus
mapping documents (ref. to page 3).
