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
Counters
In the SEL-421-0, -1, -2, -3 counters were referenced as points in the database.
None of these can be directly assigned to the counter values that are now avail-
able.
Analog Inputs
In the SEL-421-0, -1, -2, -3 analog inputs were referenced as points in the data-
base with optional type qualifiers. It is impractical to define a mapping from
these points to the data that is now available.
Analog Outputs
In the SEL-421-0, -1, -2, -3 analog outputs were referenced by index: 0–255.
These mapped to remote analogs: RA001–RA256. In the SEL-421-4, -5 these
same remote analogs are available. So, if previously, Index 0 was referenced, the
new reference is RA001. Similarly, Index 1 goes to RA002, etc.
