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.
