DNP3
DNP3 — Simulink driver blocks for communications protocols
Introduction
DNP3 is a TCP/IP-based communication protocol. The DNP3 client acts as a TCP
client connected to multiple TCP servers. The client can access the server 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 server can
include timestamp information and flags. The server 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 client and DNP3 server is provided with onboard
Ethernet interfaces and plug-in Ethernet I/O modules.
