This is because if an attempt is made to change the leftmost digit from 0 to 1, or
from 1 to 0, an upper/lower limit value check is always performed.
In order to avoid this, either set the values so that n..n x m..m, or create another
touch switch and write values to the host when digits are carried up or down.
The following settings are made for numeral settings during their creation with the
support tool. Note that restrictions apply to several of the settings made for thumb-
wheel type numeral settings.
S Referenced numeral memory table
Set the number of the numeral memory table used to record the numerical value
input using the numeral setting function.
S Number of digits in the input numerical value
Set the number of digits in the numerical values that can be input. A maximum of
8 digits (total of integer and decimal fraction parts) can be set. However, if there
is a sign display, the maximum number of digits for negative values will be seven.
S Upper/lower limits (Ver.5 direct connection only)
Set the upper limit and lower limit separately. The maximum number of digits in
the set values is eight (or seven if there is a sign display).
When the upper limit value and lower limit value are set as negative values, set
"F" as the eighth digit.
Example: Upper limit value or lower limit value is "–123" → F0000123.
S Display attribute
Set attributes in the same way as for numeral display. For details, see Numerals
Which can be Displayed (page 127).
There are the following restrictions and additional items to set when creating
thumbwheel type numeral settings.
S Number of input digits for positive values when there is a sign display
When a sign display is set for a thumbwheel type numeral setting, a maximum of
7 digits can be input for positive values.
S Display size
One of two sizes can be selected: "small" in which each digit comprises two
touch switch units, and "medium", in which each digit comprises three touch
switch units. Note that if "small" is selected the area in which the numerical value
is displayed is also the touch switch input area.
