B.7
Date Code 20171021 Instruction Manual SEL-421 Relay
Converting Settings From SEL-421-0, -1, -2, -3 to SEL-421-4, -5
DNP3 Mapping Changes
Binary Inputs (MAPSEL = E)
Table B.8 lists the mapping for points 0–15.
References 16–265 do not have a good equivalent because they were dependent
on the SER settings. For automatic remapping purposes, these references can be
extracted from the SER settings. For example, reference 16 would correspond to
setting SITM001, 17 to SITM002, etc.
References 266–271 are reserved and can map to hard ‘0’.
References 272 and above map to the Relay Word, starting at bit 0, with the
exception of those noted in Table B.8. See Section 11: Relay Word Bits for the
Relay Word.
