DPU2000R Modbus Point List Mitigation Manual
4.1.3
Logical Input Block (Double-bit data with momentary change
detection)
Like in DPU2000R, the logical input block in REF615R starts from 1x address of 10513
and ends with 1x address of 10658. The IEC61850 path for the status points are the same
as in the logical input block with single bit data. In REF615R, MCD (Momentary Change
Detect) bits are implemented and mapped in the same way and same address locations as
the momentary bits in DPU2000R.
