DNP3 Documentation
Device Profile
The DNP3 Device Profile document, available on the supplied CD or as a
download from the SEL website, contains the standard device profile
information for the SEL-787. This information is also available in XML
format. Please refer to this document for complete information on DNP3
Protocol support in the SEL-787.
Reference Data Map
Table D.10 shows the SEL-787 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-787 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-787 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.
