Protection and Logic Functions
DNP Map Settings (Set DNP n command, n = 1, 2, or 3)
Event Report Settings
Event reports can be either 15 cycles or 64 cycles in length as determined by
the LER setting. For LER of 15, the prefault length, PRE, must be in the range
1–10. The relay can hold as many as seventy-seven 15-cycle event reports or
nineteen 64-cycle event reports.
Load Profile Settings
Use the LDLIST setting to declare the analog quantities you want included in
the Load Profile Report. Enter up to 17 analog quantities, separated by spaces
or commas, into LDLIST setting. See Appendix K: Analog Quantities for a list
of the available Analog Quantities. Also set the LDAR to the desired
acquisition rate for the report.
IMPORTANT: All stored load data
are lost when changing the LDLIST.
DNP Map Settings (Set DNP n command, n = 1, 2, or 3)
Table 4.74 shows the available settings. See Appendix D: DNP3
Communications for additional details.
