PS501
Each condition in the table is processed by applying a
“comparison function” to the selected data (“condition
selection”) and the given constant (“condition thresh-
old”). The result of this operation (“true” or “false”) from
each condition in the group is combined as dictated by
the “AND-OR” “combination function” bit in the flag
byte. Because the “AND” function has precedence over
the “OR”, processing the CG can be described as
OR’ing subgroups of ANDs (see Example 7-1 below).
One 8-bit timer (clocked at 500 msec) is associated
with all 16 CSF(s). The timer compared to its threshold
is an implied “AND” term to the CG (i.e., if processing
of the CG to set the CSF results in “true”, the timer is
incremented and if timer >= threshold, the SF is set;
otherwise, the SF is not set even though the GC is sat-
isfied). If processing of the CG to set the CSF results in
“false”, the timer is set to zero. The timer is not allowed
to increment past the threshold.
The conditions in the order they are stored in memory
will build the activation equation until bit 7 of byte 1 is
set, signifying the last condition of the group. At that
point, the next group of conditions is the Reset
equation. When the next to last condition bit is set, a
new activation group begins.
EXAMPLE 7-1:
CONDITION GROUPS
Example Condition Group:
(V CELL -min < 3200) .AND. (CURR > 100) .OR. (TEMP > 60) .AND. (CURR > 200)
because of precedence the equation would be interpreted:
((V CELL -min < 3200) .AND. (CURR > 100)) .OR. ((TEMP > 60) .AND. (CURR > 200))
Example Reset Condition Group:
(V CELL -min > 3200) OR (CURR = 200)
