Communications Card
The ANALOGS region contains protection and automation variables. This
region is updated every 0.5 seconds. See Table 4.26 for the Map.
The STATE region contains elements defined with the SET R command and
an attached SOE queue that holds up to 100 records. The relay updates this
region within 0.5 seconds of any new events. Communications card protocols
that require state changes with SOE-quality timestamps must retrieve this data
from the STATE region. See Table 4.27 for the Map. See DNP LAN/WAN
Application Example on page R.6.49 for DNP LAN/WAN implementation
details.
The communications card database is virtual device 1 in the relay. You can
display the contents of a region using the MAP 1:region command (where
region is one of the database region names listed in Table 4.18). An example
of the MAP command is shown in Figure 4.4.
