When there is no sign display :0 to 99999999 (8 digits)
When there is a sign display :--9999999 to +9999999
(7 digits for negative numbers, 8 digits for positive numbers)
If a sign is displayed when using the thumbwheel type ofnumeral setting, themaxi-
mum number of digits for both positive and negative numbers is 7.
- Decimal point
A maximum of 7 digits can be input after the decimal point (or 6 for negative
numbers).
Hexadecimal input
When the display attribute is set for hexadecimal display, values are input in the
hexadecimal format.
- Numerical value range
Numerical values can be input in the range 0 to FFFFFFFF (8 digits).
Attributes that can be set
The attributes of the numerical values displayed in the input field are the same as
for numeral displays. See “Numerals Which can be Displayed” (page 130).
Upper/Lower Limit Check (Ver.5 Direct Connection Only)
When Ver.5 direct connection is used, upper and lower limits can be set for input
numerical values to prevent erroneous values that are outside the valid range be-
ing stored in the numeral memory table or notified to the PC.
The upper/lower limit check is executed when the input numerical value has been
confirmed: if the value is outside the valid range, the screen returns to its status
before input.
To use the numerical value input function safely, always use the upper/lower limit
check function. Since this function is not featured with Ver.4 and previous ver-
sions of the direct connection function, a similar check should be implemented by
using the user application software.
5-8-2 Types of Numeral Setting
There are two types of numeral setting: the numeric key type, and the thumbwheel
type.
The basic function of these two types is the same, but the screen displays and in-
put methods are different.
A maximum of 50 input fields, including both numeric key and thumbwheel types,
can be registered on one screen.
The thumbwheel type of numeral setting can only be used when using Ver.5 direct
connection with an NT600S-ST121/ST211-EV .
