Numeral Setting
Restrictions on Numerical Value Input and Attribute Setting
Upper/lower limit check (Ver.5 direct connection only)
Correct Use:
Numerical values of up to 8 digits (7 if there is a minus sign) can be input in either
decimal or hexadecimal format.
S Decimal input
When the display attribute is set for decimal display, values are input in the deci-
mal format.
- Numerical value range
The range for numerical values that can be input differs according to whether
or not there is a sign display.
When there is no sign display
When there is a sign display
If a sign is displayed when using the thumbwheel type of numeral setting, the
maximum 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).
S 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).
S 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 127).
When Ver.5 direct connection is used with an NT20S-ST121-EV3/ST122-V1, up-
per and lower limits can be set for input numerical values to prevent erroneous val-
ues that are outside the valid range being 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.
In order to use the numerical value input setting safely, always use the upper/lower
limit check function. Since this function is not featured with NT20S-ST128 and
Ver.4 and previous versions of the direct connection function, take appropriate
measures using the user application software.
