OBJECT DEFINITIONS
Input Objects
Binary input, counter, and analog input objects are fully configurable by the user. To make data
visible to DNP, it must be moved to the User region on port 16 using the SET M process to
establish what data is moved and how it is to be treated. See Section 6: Settings for more
information on using SET M. To determine the DNP map once these settings are in place, use
the DNPMAP command. See Section 5: Commands for more information on this command.
Since the only data visible to DNP is that moved by SET M, the event time stamps associated
with changed data are the timestamps of when the data changed within the User region. This
may be significantly delayed from when the data item changed within the IED. Therefore, event
timestamps should not be used for precise sequence-of-events purposes, but it may be used for
approximate timing.
Output Objects
There are 1300 binary output objects supported, of which only the first 84 are readable. Within
the control relay output block used to control the binary outputs, only the code field within the
control code byte is used; all other fields are ignored. The Latch On/Off and Pulse On/Off codes
can be used with each binary output object, however their meaning is specific to the item, as
shown in Table I.3. For more information on these bits, see Section 9: Database. The first 8
bits are in the Global region and the remaining ones are in the Local region.
