Figure 1: Snapshot of CMT in UDR view
In REF615R, user can reassign the signal to its new bit address using CMT UDR tool. As
Figure 1 shows, user can highlight the signal of "51P (3I>): PHLPTOC1: 1 Trip 51P Trip"
from the left pane, then expand the "Empty Register" from the right pane. In this example,
DPU2000R REF615R
Number of user defined registers 32 127
Register's starting address 40001 40001
Register's ending address 40032 40127
Configuration method 6x area registers PCM600 CMT tool
In REF615R, only the signals having IEC61850 paths can be re-assigned
to the user defined registers.
