•
Attributes that can be set
The attributes that can be set for numerical values displayed in input fields are
the same as those for numeral displays. See “Numerals which can be Dis-
played” (page 135).
Checking the Upper/Lower Limit
When the upper limit and lower limit of the input numeral values have been set,
erroneous numeral values outside of the range can be prevented from being
stored in the numeral memory table or notified to the host.
Caution When the numeral values entered are confirmed, upper/lower limits are
checked. Otherwise the system may operate unpredictably.
4-8-2 Type of Numeral Setting
There are two kinds of types of numeral setting: ten-key type and thumb wheel
type. Though basic functions are the same, screen displaying and inputting
methods differ between two types.
A maximum of 50 input fields (combined total for both numeric key type and
thumb-wheel type) can be registered on one screen.
Ten-key Type When any numeral value is entered by the ten-key (character key) assigned to
the touch switch, a numeral value just entered is displayed in a screen. When the
RETURN key is pressed after an input operation is completed, the numeral value
entered is written into the numeral memory table and then notified to the PC.
When there are multiple numeral setting input columns, a numeral setting input
column for input operation is also selected by the ten-key.
To use the ten-key type, it is necessary to create not only the numeral setting in-
put column in a screen but also the ten-key for input operation (Refer to page
160).

Thumb Wheel Type
By means of touch switches that can be increased/decreased every digit of nu-
meral value, a numeral value can be entered from the numeral setting input col-
umn. Every time a numeral value displayed is changed, the numeral value dis-
played is written into the numeral memory table and simultaneously notified to
the PC.
