than the

execution interval overrun occurs;

When an overrun occurs,

THE

OUTPUT INTERVAL

The

interval

at

which output occurs

is

independent from the

execution

interval,

other

than the fact

that

it must occur when the

table

is

executed (e.9.,

a

table

cannot have

a

10

minute

execution interval and output

every

15

minutes).

A single program table can have many ditferent

output interuals and conditions, each with

a

unique data

set

(Output

Array).
