3.1.3 Logical output block (Double-bit data with momentary change
detection)
Like in DPU2000R, the logical output block in REF615R starts from coil address of 513
and ends with coil address of 866. The IEC61850 paths for the status points in double-bit
block, if available, are the same as those in the logical output block with single-bit data. In
REF615R, MCD (Momentary Change Detect) bits are implemented in the same way and
mapped in the same address locations as the momentary bits in DPU2000R.

3.1.4 Physical output block (Double-bit data with momentary change
detection)
Like in DPU2000R, the physical output block in REF615R starts from coil address of 1025
and ends with coil address of 1056 using the normal speed BIO cards. Because REF615R
supports high speed BIO cards which are not available in DPU2000R, the ending coil
address for this block extends to 1088.
