Reference Data Map
Table D.12 shows the SEL-751A reference data map. The reference map
shows the data available to a DNP3 master. You can use the default map or the
custom DNP3 mapping functions of the SEL-751A to retrieve only the points
required by your application.
NOTE: Dead-band changes via
Object 34 are not stored in nonvolatile
memory. Make sure to reissue the
Object 34 dead bands after a warm
(STA C) or cold start (power cycle).
The SEL-751A scales analog values by the indicated settings or fixed scaling
indicated in the description. Analog dead bands for event reporting use the
indicated settings, or ANADBM if you have not specified a setting.
113 All Virtual Terminal Event Data
N/A No object required for the following
function codes:
13 cold start
14 warm start
23 delay measurement
13, 14, 23
a
Supported in requests from master.
b
May generate in response to master.
c
Decimal.
d
Hexadecimal.
e
