DNP3

DNP3 — Simulink driver blocks for communications protocols

Introduction

DNP3 is a TCP/IP-based communication protocol. The DNP3 master acts as a TCP client connected to multiple TCP servers, so-called outstations. The master can access the outstation data, such as analog inputs, counters, and binary outputs, by sending read, control, and freeze requests. In addition to the actual value, responses from the outstation can include timestamp information and flags. The outstation can also send messages autonomously once a data point changes (unsolicited messaging). These events can be assigned to different event classes.

Versatile support for DNP3 master and DNP3 outstation is provided with on-board Ethernet interfaces and plug-in Ethernet I/O modules.
