Applicable
CPU
Modules
Valid
Devices
For
the
valid
device
address
range,
see
pages
and
(
Basic
Vol.).
Since
the
DJNZ
instruction
is
executed
in
each
scan
while
input
is
on,
a
pulse
input
from
a
SOTU
or
SOTD
instruction
should
be
used
as
required.
The
label
number
can
be
0
through
127
(all
‐
in
‐
one
CPU)
or
0
through
255
(slim
CPU).
Make
sure
that
a
LABEL
instruction
of
the
label
number
used
for
a
DJNZ
instruction
is
programmed.
When
designating
S2
using
a
data
register,
the
value
for
the
label
is
a
variable.
When
using
a
variable
for
a
label,
make
sure
that
all
probable
LABEL
numbers
are
included
in
the
user
program.
If
a
matching
label
does
not
exist,
a
user
program
execution
error
will
result,
turning
on
special
internal
relay
M8004
and
the
ERR
LED
on
the
CPU
module.

When
input
is
on,
the
value
stored
in
the
data
register
designated
by
S1
is
decremented
by
one
and
is
checked.
If
the
resultant
value
is
not
0,
program
execution
jumps
to
address
with
label
0
through
127
(all
‐
in
‐
one
CPU)
or
255
(slim
CPU)
designated
by
S2.
If
the
decrement
results
in
0,
no
jump
takes
place,
and
program
execution
proceeds
with
the
next
instruction.
This
instruction
is
available
on
upgraded
CPU
modules
with
system
program
version
210
or
higher.
