Displaying the numeral memory table

Numerals can be displayed in three different ways according to the contents of the numeral memory table, 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.

Hexadecimal display:	All digits are handled as stored in the allocated
	words.
Decimal display without signs:	If the most significant digit is “F”, it is handled
	as “0”, and the most significant digit other than
	“F” and other digits are handled as stored in the
	allocated words.
Decimal display with signs:	If the most significant digit is “F”, it is handled
	as “--” (minus sign), and the most significant
	digit other than “F” and other digits are handled
	as stored in the allocated words.

￿[Numeral memory table display examples]

When the data are numeral data (0 to 9)

Start 3 4 5 6

Start￿+ 1 F 0 1 2

Decimal without sign	123456
Decimal with sign	--123456
Hexadecimal	F0123456

When the data contain characters (A to F)

Start 3 B 5 6

Start + 1 F 0 1 2

Decimal without sign	123B56
Decimal with sign	--123B56
Hexadecimal	F0123B56

If the hexadecimal data (A to F) are stored when the decimal display has been set, the￿alphabets are displayed.

Reference If the number of display digits has been set to be smaller than the maximum 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.

The actual display will vary according to the “zero suppress” setting and decimal fraction setting as well as the contents mentioned above. Refer to the “NT-se- ries Support Tool Operation Manual” (V028-E1-01).
