Application manual
Figure 33 shows both instances of ANALOGREPORT function blocks. The
instance number is visible in the bottom of each function block. For each instance,
there are three separate ANALOGREPORT blocks capable of reporting up to 24
Analog signals (8 Analog signals in each ANALOGREPORT block). These can
include for example transfer of active and reactive power or reporting the
milliampere input signals to the PDC clients as defined in IEEE C37.118 data
frame format.

Figure 34 shows both instances of BINARYREPORT function blocks. The instance
number is visible in the bottom of each function block. For each instance, there are
three separate BINARYREPORT blocks capable of reporting up to 24 Binary
signals (8 Binary signals in each BINARYREPORT block). These binary signals
can be for example dis-connector or breaker position indications or internal/
external protection alarm signals.
