OV3.3 PROGRAMMING
SEOUENCE
ln routine applications, sensor signals are
measured,
processed over some time interual,
and
the results are stored in Final
Storage.
A
generalized programming
sequence
is:
1.
Enter the
execution interval, determined by
the desired sensor
scan
rate.
2.
Enter
the InpuUOutput Instructions required
to measure the sensors.
Enter
any Processing lnstructions required
to get the data ready for Output Processing.
Enter
a Program Control Instruction to test
the output condition and Set the Output
Flag when the
condition is met. For
example, use lnstruction 92 to output based
on
time, 86 to output each time the table
is
executed, and 88 or 89 to
compare input
values. This
instruction must precede
the
Output Processing Instructions.
Enter the
Output Processing Instructions to
store processed
data in
FinalStorage. The
order
in
which
the data are stored
is
determined by
the order
of
the Output
Processing
lnstructions
in
the table.
Repeat steps 4 and
5
for output on different
intervals or conditions.
