DNP3 in the SEL-751A
Configurable Data
Mapping
One of the most powerful features of the SEL-751A implementation is the
ability to remap DNP3 data and, for analog values, specify per-point scaling
and dead bands. Remapping is the process of selecting data from the reference
map and organizing it into a data subset optimized for your application. The
SEL-751A uses object and point labels, rather than point indices, to streamline
the remapping process. This enables you to quickly create a custom map
without having to search for each point index in a large reference map.
You may use any of the three available DNP3 maps simultaneously with up to
three unique DNP3 masters. Each map is initially populated with default data
points, as described in
Default Data Map on page D.26 . You may remap the
points in a default map to create a custom map with up to:
