DNP3 Protocol Explained in Details

 

DNP3 Protocol or stack is an abbreviation for Distributed Network Protocol which is simply a set of communication protocols used in utilities such as the water and electric companies.  It is uncommon for other companies to use DNP3 stack. The use of DNP3 stack is advantageous since it eases communication between different types of equipment that are used in collection of data.

 

For supervisory management and control DNP3 protocols are used.  To pass data from master stations to Remote terminal units or intelligent electronic Devices (IEDs) the SCADA systems rely heavily on DNP3 protocols.   

 

It's interesting how the DNP3 protocol came into being.  A standard that would permit interoperability between different vendors SCADA components for the electrical grid was needed since the IEC 60870-5 was under development. 

 

DNP3 protocol gives dependable communications in the remote areas that are not suitable for installing electric utility automation systems.  The use of DNP3 protocol could help overcome the distortion induced by the EMI. The aging components could be made to last longer by using the DNP3 stack.  Drastic improvement in transmitting of data would be witnessed when DNP3 protocol is used.

The DNP3 stack was developed in such a way it would be reliable.  However, its security is questionable.  The DNP3 protocol could be interfered with by any malicious person or hacker since it's not that secure. If the DNP3 protocol is the major communication stack major critical infrastructure and control systems could be rendered out of operation due to how insecure the DNP3 stack is.  However, there has been recent development that has contributed to improved security of the DNP3 stack.  Improved security brought about by the authentication features that have been added to the DNP3 stack assures the usage of this protocol. Since the DNP3 protocol complies with IEC 62351-5 they are deemed suitable.  The compliance of DNP3 protocol with the IEC 62351-5 makes it less challenging when switching to either of the two.

 

The suitability of the DNP3 protocol is brought about by its firmness, efficiency and ability to be interoperable than the aged protocols which is as a result of its strong features. Due to its complexity the DNP3 stack cannot be compared with other protocols.  Watch this website at https://www.youtube.com/watch?v=4hOOq-f5PVA and learn more about DNP3.

 

Settle for DNP3 protocol if you want a stack that offers multiplexing and data fragmentation. DNP3 protocol is good since it could help check for errors and link control.

 

Time synchronization with a RTU could be supported by the DNP3 stack. The DNP3 60870 stack could be able to receive adequate data to reconstruct a sequence of events that happens in between the polls.  Any company should consider in depth the advantages and disadvantages of the DNP3 protocol and indeed any other protocol.
