4.1.4 Physical input block (Double-bit data with momentary change
detection)
Like in DPU2000R, the physical input block in REF615R starts from 1x address of 11025
and ends with 1x address of 11056 using the normal speed BIO cards. Because REF615R
supports high speed BIO cards which are not available in DPU2000R, the ending 1x
address for this block extends to 11102.
The IEC61850 path for the status points are the same as in the physical 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.
