Figure 3.15 SEL-651R Communications Settings for P2MP
The SEL-651R has a minimum of four settings to get the link up and running. There
are more settings to determine types and mapping of digital and analog data but are not
needed to verify initial operation. This example only demonstrates on how to get the
RTAC communicating to the SEL-651R through the SEL-3031 in P2MP mode.
Figure 3.15 shows the first setting needed in the SEL-651R. The settings are needed in
all remote SEL-651R units communicating to the RTAC. The PROTO needs to be set
to DNP for the current protocol used. The SPEED needs to be set to 38400 to match the
system baud rate. The rest of the settings in this group can be left as default.
Figure 3.16 shows the settings for the DNP port set in the SEL-651R.
