Description

This chapter provides detailed information about the DNP3 feature.
Status, analog and digital data are available in DNP3 registers. Access to SCADA
integration is provided via Ethernet interface. The DNP3 functionality is fully
dependent on the MODBUS functionality. To use DNP3, it is necessary for a
configuration key to unlock the MODBUS functionality.
Each register reports 16-bit data. Registers are divided into 3 groups, status, analog
and digital channels.
For each digital channel added to the DNP3 library database, a number is associated.
These numbers are integers and start at zero. The number associated follows the
order that the digital channels are created at equipment configuration.
For each analog channel added to the DNP3 library database, a number is
associated. These numbers are integers and, for analog channels, start at number
five. The number associated follows the order that the analog channels are
configured at the M
