Common Variables (#1 00 through
49, #500
through #559)
A
common variable may be shared by
macros
and through all macros of all nesting levels. That
is, the common variable enables a macro to refer
to the results obtained by another macro.

Common variables are divided into the following
two types depending on clear conditions:

#100 through #149:
These common variables
are cleared at the time of power-on and reset
operations and are set to
They are not
cleared by reset operation in some controls if
parameter #6008 D 1 is set to “ 1.”
B.
#500
through 559
These common variables
are not cleared at the time of power-on and reset
operations.
The
common variables are available to the
user without restrictions.
They cannot be
designated by arguments. Indirectly, however,
they can be designated as follows:
