Notice that we divided the voltage data by 100, so the read value will be in tenths of kilovolts.
4. Use the DNPMAP command to determine the object types and indexes of the binary input,
counter, and analog input objects you have selected:

5. The data are now ready to be read. Configure your master to perform Class 0 polls to read
all of the static data. You can also selectively read data. Use the map obtained above with
the DNPMAP command to interpret the data.
6. You can also perform control using this interface by writing to binary outputs. The binary
outputs are not configurable; they are listed in tables I.3 and I.4 above. Thus, to cause the
relay on port 1 to open its breaker, you need to pulse the 1:SBR1 bit by performing a latch on
or pulse on operation (direct operate or select-before-operate) to the binary output object 96.
Similarly, to cause the relay on port 1 to close its breaker, you need to pulse the 1:CBR1 bit
by operating the binary output object 128.
