UDR 40001 is chosen. (Bit address 0x010 means 40001:00, and 0x1F means 40001:15,
and 0x20 means 40002:00 etc). Select the first bit address, and click on the “Go to right”
button between the two panes, the signal will be remapped to the right pane as Figure
2 shows.
Figure 2: Snapshot of 51P remapped to 40001:00
Please note at the left pane, signal "51P (3I>): PHLPTOC1: 1 Trip 51P Trip" appears three
times as Table 10 shows, it is because the signal is mapped three times at coil address: 12,
535 and 40897:4:

To remap the signal with double bits to UDR, one can pick up the signal with name
containing "MOM". To map the signal with single bit to UDR, one can pick up the signal
from either of the other two options.
5.1.1.2 Example of remapping an analog register to UDR
The purposes of remapping the analog measurement signals are often to change the
scaling, and the offset, or to shift or clamp the data values, etc.
REF615R PCM600/CMT/UDR offers four scaling options: No scaling, Ratio scaling,
Multiplicative scaling and Divisor scaling.
5.1.1.2.1 No scaling
The UDR will simply inherit its original register's scaling factor.
item Snapshot from PCM600 CMT UDR view left pane Modbus addresses of the signals
1 Double-bit with MCD, address coil
535 for status (MOM bit), and coil
536 for change detect (MCD bit).
2 Single-bit, either coil address 12 or
4x address of 40897:4
3 Single-bit, either coil address 12 or
4x address of 40897:4
The discrete signals packed into a UDR do not have to be in the same
sequence as in theoriginal register. Moreover, the UDR can be packed with
different discrete signals than what the original register contains.
