Inputting Numeric Values
Reference: Numeral memory tables store numeric values as signed binary data.
Permissible Input Range
When inputting values into numeral memory tables, the permissible input range
is affected not just by the Display Type and Display Sign but also the Storage
Type and Words settings. (When numeral memory tables are not allocated
words in the host, the Words setting is treated as 2 words.)
The permissible input range is determined as follows depending on these prop-
erties. If input of a value outside this range is attempted, the PT checks and pre-
vents the input.
Relationship Between Input Numeric Values and Contents of Host Words
When inputting a numeric value to a numeral memory table allocated to a word
at the host, the value is first converted to signed binary in accordance with the
settings for Display Type and Display Sign settings and stored in the numeral
memory table, and then written to the host word in accordance with the Words
and Storage Type settings for the numeral memory table. Therefore the result
Storage
When the word allocated in the host is input to a 1-word memory table, the in-
put value is treated as 4-digit (16-bit) signed binary data so it is converted to
8-digit signed binary data before being stored.
For example, if a value of 8001 hexadecimal is input to a 1-word numeral
memory table, it is recognized as a negative value because the most signifi-
cant bit is ON. The value actually stored in the numeral memory table is
FFFF 8001 hexadecimal.
