industrial control systems. It is an open communication protocol which is
flexible and widely used. DNP3 is in line with the open protocol standards
used in various types of networks.
DNP3 Features
These are the features of DNP3.
• Object-oriented communication
DNP3 describes and processes data in the object-oriented way, thus
reflecting the dynamic characteristics in changing incidents.
• Multiple data types
The request and response messages can contain a variety of data types
(data objects).
• Multi-master station
A slave station can communicate data with multiple master stations.
• Unsolicited upload
The slave station can send unsolicited information to the master station.
This is called an exception report. Functions such as self-reporting on
changes, incident order recording and accident recall are available.
