Memory Table Entries and Bar Graph
Section 5-3
• Displaying the numeral memory table entry
Numerals can be displayed in three different ways according to the con-
tents of the numeral memory table entry, as mentioned below.
The most significant digit (digit 4 of a single word or digit 8 of a double
word) is processed in different ways.
Decimal display without signs: If the most significant digit is “F”, it is han-
dled as “0”, and the most significant digit
other than “F” and other digits are han-
dled as stored in the allocated words.
Decimal display with signs: If the most significant digit is “F”, it is han-
dled as “–” (minus sign), and the most
significant digit other than “F” and other
digits are handled as stored in the allo-
cated words.
[Numeral memory table display examples]
• When the data are numeral data (0 to 9)
• When the data contain characters (A to F)
If the hexadecimal data (A to F) are stored when the decimal display has
been set, the alphabets are displayed.
If the number of display digits has been set to be smaller than the maxi-
mum number of digits of the registration words (4 digits for 1 word; 8 digits
for 2 words), the contents of the allocated words are not displayed and “*”
symbols will be displayed at all digits.
If the most significant digit is “F” when “decimal with signs” has been set,
the numeral is handled as a negative number. The maximum number of
digits of the negative number becomes smaller than that of the positive
number by 1 digit.
Reference The actual display will vary according to the “zero suppress” setting and deci-
mal fraction setting as well as the contents mentioned above. Refer to the “NT-
series Support Tool Operation Manual” (V061-E1-
@ ).
• Contents of the character-string memory table entry
A character-string is stored in the allocated words beginning with the first
word in half-size characters.
Two half-size characters are stored in one word. One memory table entry
can store up to 10 words (20 characters).
