[https://en.wikipedia.org/wiki/DNP3 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. Competing standards include the older Modbus protocol and the newer IEC 61850 protocol and IEC 61870.
