Inputting Numeric Values Using a Thumbwheel Type Input Field
The following describes the procedure for inputting a numeric value into a thumb-
wheel type input field.

[Setting]
When creating a screen using the Support Tool, register the following element for
the screen.
- Numeral setting input field (thumbwheel type)
Reference: Since a thumbwheel type numeral setting field itself has a touch switch for input-
ting a numeric value, it is not necessary to register other elements for inputting a
numeric value.
[Operation]
(1) Display a screen which has a thumbwheel type numeral setting field.
(2) Change the numeric value using the increment/decrement (+,
−
) keys pro-
vided at the top and bottom of each digit position of the thumbwheel type nu-
meral setting field.
For the procedure for changing a numeric value, refer to “Using a thumbwheel
type input field” (page 533).
Reference - In a thumbwheel type numeral setting field, a numeric value is confirmed imme-
diately after it is changed and written to a numeral setting field. At the same
time, the occurrence of a change in the contents of the numeral setting memory
table is notified to the host.
- When a thumbwheel type numeral setting field is displayed, the numeric value
which has been stored in the numeral memory table prior to the input is dis-
played.
- Even if more than one thumbwheel type numeral setting field exists on a screen,
specification of an objective input field is not necessary since input is performed
by using the thumbwheel switch in the required input field.
- If the “upper/lower (max./min.) limit check” function is set for the numeral setting
input field, the function checks if the input numeric value falls within the specified
range when the input is confirmed. If the numeric value is outside the specified
range, the buzzer sounds three times, the input numeric value is canceled, and
the screen returns to the display before starting the input. In this case, neither
writing to a numeral memory table nor notification to the host is executed.
