Program modules
According to
the
need, the desired program module
is
connected for an immediate program execution.
®
Two program modules can
be
used at
the

When used as
the
program module,
no
user area can be
contained. But, if the module has been d
ivi
ded into a
program module and a user area using
the
INIT state-
ment, only
the
declared user area conforms
to
the
user
area of (1),
Creating
the
program module:.
After declaring
the
program area with
the
INIT
state·
ment,
the
program
is
written or loaded
to
that
area.
The
memory
protected
CE·159, CE.161,
or

must
be
used
for
the
program module.
RAM

test
1. Static electricity
stor~
in human
body
must be released
before removal
of
the
board.
2. First, remove
the
lithium
battery,
and check for a short
circuit between electrodes and diodes using an ohm·

power
supply source as shown
in
the
figure below and check
that
the
