    IEC 61850 path as well. The DPU2000R relay was developed by ABB in the 1990s and has served the industry successfully for over a decade. As time went by, some of its hardware components and software design modules have become obsolete, restricting its use in the future power grid network communication systems.

    Section 3 1MRS240173-IB B 0x registers TRIPA, TRIPB, TRIPC are mapped to different coil addresses in REF615R with those in DPU2000R. 3.1.2 Physical output block (Single-bit data) REF615R inherits the same layout of physical I/O channels from DPU2000R. Besides DPU2000R's normal speed I/O card, REF615R offers high speed I/O cards. As a result, REF615R extends Modbus points for physical output block (single-bit data) to the coil address of 288.
