Overwhelmed by the Complexity of Communications? This May Help

DNP3 Protocol Explained in Details A set of communication protocols commonly used by water and electric companies includes the DNP3 stack which is an abbreviation for Distributed Network Protocol. DNP3 stack is not common with other companies. The main reason the DNP3 stack was developed is to ease communication between different kinds of equipment that are used to collect data. For supervisory management and control DNP3 protocols are used. SCADA systems rely heavily on DNP3 stack especially to pass data from master stations to Remote Terminal Units or intelligent electronic Devices (IEDs). The way DNP3 stack came about is fascinating. Since the IEC 60870-5 was under development there was a need to have a standard that would permit interoperability between different vendors SCADA components for the electrical grid.
A Beginners Guide To Options
DNP3 protocol gives dependable communications in the remote areas that are not suitable for installing electric utility automation systems. The DNP3 stack helps to overcome distortion caused by EMI. The aging components could be made to last longer by using the DNP3 stack. Through the use of DNP3 protocol poor transmission media would improve drastically.
The Beginners Guide To Protocols (Finding The Starting Point)
The reliability of the DNP3 stack cannot be questioned. DNP3 protocol is not that secure. Actually it’s not that secure and it could be attacked by any hacker or spiteful people. Due to the level of insecurity associated with DNP3 major critical infrastructure and control systems could come to a standstill if malevolent forces come into play. 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. The suitability of the DNP3 stack comes in such that they are compliant with the IEC 62351-5. Just by adding a few features you would not have to change DNP3 protocol if you want to incorporate IEC 62351-5. The features of the DNP3 stack makes it firm, efficient and have the ability to be interoperable than the aged protocols. The complexity of the DNP3 protocol cannot be compared with any other source code. If you need a protocol that offers multiplexing and data fragmentation you need to settle for DNP3 stack. To check for errors and link control you could use the DNP3 protocol. Another advantage of the DNP3 protocol is their support of the time synchronization with a RTU. The sequence of events that happens in between the polls could be received adequately by the DNP3 stack to reconstruct data. To ensure that the protocol a company settles on is adequate a thorough research and analysis should be carried out.
