<Permissible input range>
The permissible input ranges depending on the settings made for "Display Type"
and "Display Sign" are indicated in the examples below.

When writing to numeral memory tables that are allocated to host words, not
only the properties of the numeral setting input field but also the "Storage Type"
and "Words" settings made for the numeral memory table have an effect on the
permissible input range. The permissible input range is determined as follows
depending on these properties. If input of a value outside this range is at-
tempted, the NT31/NT31C checks and prevents the input.

* Note that the values are different from those of the numeral display range. In
numeral display, since negative numbers are displayed as absolute values when
displaying unsigned decimal values, "32768" and "2147483648", which cannot be
input, may be displayed.
