TIMER

FUNCTION

This

instruction will reset a

timer or

store

the

elapsed

time

registered by

the timer

in

an Input

Storage

location. Instruction 26

can

be

used

with

Program Control

instructions

to

measure

the

elapsed time between specific

input

conditions. There

is

only

one timer

and

it is

common to

alltables

(e.9.,

if the

timer

is reset

in

Table 1

and

later

in Table 2,

a subsequent

instruction

in Table

1

to read

the timer will store

the elapsed time

since

the

timer was

reset

in

Table

2).

Elapsed time is

tracked in 0.1

second

increments

but displayed as an integer. For

example, a 20

second

elapsed

time

is

d

as

"200".

The time starts over

after

reaching

a

maximum value

of 65,536

-

about

109

minutes.

The timer is also reset in response to certain

keyboard entries:

When tables

are

changed

and

compiled

wit

the

*0

Mode,

the

timer is reset

automatically.

When tables are

changed

and

then

compiled

in

the

*B

Mode,

the

timer is

automatically reset and Tables

1

and 2 are

disabled.

Entering

u*Oo

at this

point

enables

both

tables

and

resets the

timer.

3. Entering

""6"

after changing the tables

compiles

the

programs,

but does

NOT

the

timer.

***

The

8 channel

IntervalTimer

(lNT8)

is a

measurement module

which

provides

timing information to

the

datalogger.

Each

of

the 8 input channels

may

be

independently

configured to detect either rising

or

falling

of

either

high level

or

a low level

signal.

Each

channel may

be

independently

programmed.

See the SDM-lNT8 manualfor detailed

instructions

and examples. This instruction

is

not in

all

PROM

options.
