4-8-5 How to Use Thumbwheel Settings
Entering the Numeric Values
Numeral Setting
For numeral setting with a thumbwheel, a numeric value is entered by directly
touching the increment/decrement (+, --) keys. Keys such as numeric key are not
required.
The numeric values are entered using the increment/decrement (+, --) keys pro-
vided at each digit.
S Specifying the Numeric Values
S Changing Signs
S Checking the Upper/Lower Limits
When the increment/decrement (+, --) key is touched, the numeric value at that
digit will increase/decrease by 1. Each time + or -- key is touched, the numeric
value just changed is notified to the PC. It is not necessary to press the RE-
TURN (
A numeric value cannot be entered into the thumb wheel type from the ten-key.
In case of sign display setting, the sign + is specified by touching the + key of
the digit for which the sign is displayed and the sign -- by touching the -- key.
Upper/lower limits are checked when pressing the increment/decrement (+, --)
keys. If it is found that an input numeral value is in excess of the limit as a result
of checking, the contents of the numeral memory table entry (previous value
before pressing the increment/decrement (+, --) keys) is displayed again, but
this is not notified to the PC.
With the thumb wheel type, if the upper limit is 1n...n and the lower limit is
0m...m (n and m represent digits), and n...n < m...m, it is not possible to change
between numbers with a different number of digits.
For example, if the upper limit is 1,200 and the lower limit is 201, if the initial
value has 3 digits then it will be possible to change within the range 201 to 999,
and if the initial value has 4 digits, it will be possible to change within the range
1,000 to 1,200. It will not, however, be possible to change between these two
ranges.
This is because, when an attempt is made to change the leading digit from 0 to
1, or from 1 to 0, the upper/lower limit check stops the change. In order to avoid
this, set an upper and lower limit so that n...n ² m...m, or set up a separate
touch switch and use this touch switch to write the new value when changing
between values with a different number of digits.
