Connecting to a SEL RTAC using DNP3

In this example, DnpClient is used to connect to a SEL RTAC acting as DNP3 slave over TCP.

• Step 1: Obtain information about the DNP3 slave configuration. See below example of the RTAC configuration:

Figure 10: SEL RTAC configuration of a DNP slave

• Step 2: First create the driver DnpClient instance, then create the channel. Once inside this channel, create the device. See below example of channel and device settings:

• Step 3: Create and configure the tags. See below examples for how the tag sources should be configured in order to read the first analog input (index 0) and write to the first analog output (index:0):

Figure 12: Source configuration settings for the first Analog input (Group 30, Index 0). The variation is determined by the RTAC.
