4.28 DNP3 Slave – Configuration
The DNP3 Slave Configuration page allows slave setup parameters to be edited ‘outside’ of the RTU logic application. By default the
‘Overwrite Link Settings’ and ‘Overwrite Link Settings’ are disabled. If these fields are enabled, the RTU will read the DNP3 settings
defined here, rather than the settings defined in the logic application. Note: these values are only read after a RTU restart/boot.
Since DNP3 slave version 3.1.55.910, the
RTU32 Series supports both standard and
extended versions of the dnp3s.ini file.
The standard version allows access to slave
and master address, endpoint type and
communications settings. The extended
version includes additional application layer
settings such as event buffer sizes,
unsolicited reporting rules and device
attributes, as shown below.
The extended dnp3s.ini file can be
created/edited from the ‘Edit Config File’
web page, or generated and sent from a
SCADA Host (using FTP or DNP3 File
Transfer). Note: the RTU must be restarted
for the dnp3s.ini file changes to be read. A
restart can be triggered from logic, from the
web page, or from the SCADA Host (using
DNP3 warm reset or cold reset).
