PROTOCOLO DNP3 PDF

Distributed Network Protocol 3 DNP3 is a set of communications protocols used between components in process automation systems. Its main use is in utilities such as electric and water companies. Usage in other industries is not common. It was developed for communications between various types of data acquisition and control equipment.

DNP3 Distributed Network Protocol has been used by electric companies for over twenty years and has recently started to be adopted in the water industry as well as for oil and gas applications. DNP3 has two main advantages. First, it supports unsolicited responses, so a DNP3 field device or outstation can actively send messages when a specific event occurs. Second, it supports the timestamp feature, so data can be tracked regardless of the frequency of polling.

Because of these advantages, DNP3 is very popular in telemetry systems and a significant number of field devices and control equipment are already utilizing it.

As the network infrastructure for communications technologies is changing rapidly, there are many networks that have recently been retrofitted and many more that will need to be retrofitted in the near future in order to keep up with the new trends that are emerging. When a project deployment is underway, the system integrator must overcome several challenges. Second, when embedded computers are used for serial-to-Ethernet commissioning, engineers have to spend a lot of time on protocol conversion as opposed to system automation, which is the main task that engineers have been hired to perform.

Last, as the majority of engineers who work on these deployments are not familiar with the protocols that are used to solve communication issues, the deployment will typically take longer and therefore incur increased operational costs. As all of these conversions can be performed within a single model, the need to purchase, deploy, and set up multiple devices to perform all of these conversions is eliminated.

The MGate can either convert protocols using the transparent mode, or perform different roles, such as acting as an agent to communicate with the field devices. Protocol conversion is challenging because engineers need to understand the roles of the system and configure different parameters correctly. The MGate can also auto detect the points index for each binary input, binary output, counter, analog input, and analog output.

For troubleshooting or management purposes, users can first monitor the system status by using the diagnose function, which detects the communication status of the DNP3.

Rather than simply echoing the data, it presents the data in an intelligent, easy-to-understand format with clearly designated fields, including source, type, destination, contents, as well as several other fields. Events can be filtered in different ways and the complete log can be saved as a file for later analysis.
