Binary inputs (objects 1 and 2) are supported as defined by the previous table. Binary inputs 0
599 and 1200 1223 are scanned approximately once per second to generate events. When time
–
is reported with these event objects, it is the time at which the scanner observed the bit change.
This may be significantly delayed from when the original source changed and should not be used
for sequence-of-events determination.
In order to determine an element's point index, consult the Relay Word Bits table in Section 9:
Setting the Relay. Locate the element in question in the table and note the Relay Word row
number. From that row number, subtract the row number of the first Relay Word row (usually 2)
and multiply that result by 8. This is the index of the right-most element of the Relay Word row
of the element in question. Count over to the original element and add that to get the point
index. Binary Inputs 600
carry the time stamp of actual occurrence. Static reads from these inputs will show the same
data as a read from the corresponding index in the 0
the SER list (SET R) will generate events in the 600
Analog Inputs (objects 30 and 32) are supported as defined by the preceding table. The values
are reported in primary units. Analog inputs 28
scaled according to the DECPLM setting (e.g., if DECPLM is 3, then the value is multiplied by
1000). Analog inputs 58
(current magnitudes) are scaled according to the DECPLA setting. The even-numbered points in
8 15 and 22 27 (voltage magnitudes) are scaled according to the DECPLV setting. Analog

inputs 36 41, 106, and the odd-numbered points in 0

100. The remaining analogs are not scaled.
Event-class messages are generated whenever an input changes beyond the value given by the
ANADB setting. The dead-band check is done after any scaling is applied. The angles (the odd
numbered points in 0
band check, the corresponding magnitude (the preceding point) contains a value greater than the
value given by the ANADB setting. Analog inputs are scanned at approximately a 1-second rate,
except for analogs 103
initiated. Analogs 103
