Binary inputs (objects 1 and 2) are supported as defined by the previous table. Binary inputs 0 -
499 and 1000 - 1023 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 change and should not be used for
sequence-of-events determination. In order to determine an element’s point index, consult the
Relay Word Bits tables in Section 9: Setting the Relay (see Table 9.3). 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
