Chapter 4 – Configuration
18 DNP3
The DNP3 functionality is fully associated with the MODBUS functionality in the RPV311. To use the DNP3
protocol, it is necessary to insert a configuration key at the equipment to unlock the MODBUS and DNP3
functionalities. However, it is necessary to check the HABILITATED option at the web interface and insert
analog channels block or digital channel blocks at MODBUS/DNP3 menu.
18.1 CONFIGURING THE DNP3 FUNCTION
To add binary data to the DNP3 slave database (RPV311), it’s just necessary to add a digital channel in the
equipment’s configuration, as shown at section 7. At the RPV311 restarting proccess, the DNP3 library reads
the configuration archive and adds digital channels sequentially, associating to an integer number plus an
increment, starting at zero, for each digital channel. GOOSE digital channels are not added to the DNP3
database.
18.2 DNP3 CONFIGURATION EXAMPLE
18.2.1 ADDING DIGITAL CHANNELS
First step for digital channel DNP3 database association is to create a digital channel. Figure 43 shows the
digital channels configured and table below shows associated number at the DNP3 database for each digital
channel of the example.
