c. If the primary PT rating is 20KV, to get the primary voltage reading in KV, fill in five
into the "Min In" column. It is because the original signal's scale factor is already 100.
Thus, 20 (1/5*100 = 20) will be UDR's value's effective scaling. (It eventually
multiplies voltage per unit reading by 20).

System Status/Configuration Block
REF615R keeps as many status registers in DPU2000R as possible for the purpose of self
diagnostics. The mappings for some registers without direct IEC 61850 paths, such as
"heart beat", are implemented by software. Some registers in DPU2000R mapped for its
obsolete hardware or device configurations are reserved as blanks.
Table 11:
Mitigations of Modbus system status/configuration block
If the original signal is mapped into 32 bit, the UDR shall keep it as 32 bit
register by leaving the next register as "Empty Register".
