DNP3 — Simulink driver blocks for communications protocols
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.
