If ANI0 is less than ANI1, the following event sequence occurs as described in Table 3-6:
Table 3-6. High/Low Selector - ANI0 < ANI1
Step
Module
Input(s)
Output(s)
Comments
1
ANI
ANI0 (C020) and
ANI1 (C021).
2
Math A
ANI0 (B123) and
ANI1 (B124).
L098 = 0
(False compare, ANI0
< ANI1).
3
Logic A
B127 = 1 and
B128 = 1.
L097 = 1.
FC = 128 or A NOT;
therefore, two 0’s in =
a 1 out.
4
SP Gen 0
B149 = 1, which
inhibits setpoint
tracking (the 1 input is
inverted to a 0 within
the SP Gen 0 module).
B148 = ANI0 value
(from step 1 output)
B150 = ANI1 value
(from step 1 output)
B151 is tied to a
steady 1 from L071,
which enables remote
setpoint.
C101 = ANI1
L104 = 0 to indicate
setpoint tracking is not
selected.
Remote setpoint is
enabled.
5
Logic B
B130 = 0 and
B131 = 0.
L096 = 1, which
inhibits B142 of Param
D (ANI1 span).
FC = 128 or A NOT;
therefore, two 0’s in =
a 1 out.
6
Param C
B139 = L104 (0 from
step 4 output), whic
inhibits Param C
output.
7
Param D
B142 = L096 (1 from
step 5 output), which
enables Param D
output.
B144 = ANI1 span
value.
The ANI1 span value
is gated through the
Param D module to
datapoint C005.
8
Datapoint
C005
C005 = B144 (from
step 6 output).
ANI1 span value.
9
Math B
B162 = C101 (ANI1
value from step 4 SP
Gen 0 output ).
B163 = ANI1 span
value from C005.
C031 = ANI1 value
augmented by the
Math B function code 4
algorithm.
10
ANO’s
B100 = C031, which is
the augmented ANI1
value.
ANO0 = B100 =
augmented ANI1 value.
