* Note that this range is different from that for numeral input (page 188). 32768 is
displayed when the contents of the numeral memory table are 8000
and 2147483648 is displayed when the contents of the memory table are
80000000H (–2147483648). This is because when the value is unsigned, only the
sign is omitted and the numeric value is displayed as an absolute value. It is not
possible to input 32768 or 2147483648 as positive values.
Relationship Between Contents of Host Words and Displayed Numeric
Value
When displaying the contents of a numeral memory table allocated to a word at
the host, the contents of the word are first converted to the format for storage in
the numeral memory table (signed hexadecimal), and then converted again in
accordance with the settings for Display Type and Display Sign settings in order
to display them. Therefore the result also differs according to the settings made
for Words and Storage Type.
Set the data format (decimal/
hexadecimal) in which the
numeral memory table values
will be displayed.
(Set in the Numeral Display
properties.)
