Device Profile
The DNP3 Device Profile document, available on the supplied CD or as a down-
load from the SEL website, contains the standard device profile information for
the relay. This information is also available in XML format. Please refer to this
document for complete information on DNP3 Protocol support in the relay.
Reference Data Map
Table 16.9 shows the common portions of the relay DNP3 reference data map.
See Section 10: Communications Interfaces in the product-specific instruction
manual for a complete DNP3 reference map for that relay. You can use the
default map or the custom DNP3 mapping functions of the relay to include only
the points required by your application.
The entire Relay Word (see Section 11: Relay Word Bits in the product-specific
instruction manual) is part of the DNP3 reference map. You may include any
label in the Relay Word as part of a DNP3 custom map.
The relay scales analog values by the indicated settings or fixed scaling. Analog
inputs for event (fault) summary reporting use a default scale factor of 1 and dead
band of ANADBM. Per-point scaling and dead band settings specified in a cus-
tom DNP3 map will override defaults.
