DNP3 Serial Application Example
Application
This example uses an SEL-421 connected to an RTU over an EIA-485 network.
The RTU collects basic metering information from the relay. The network for this
example is shown in Figure 16.6.
The metering and status data that the RTU collects from the relay are listed in
Table 16.11.
