Input of Numeric Values and Character Strings
Section 8-7
[Setting]
When creating a screen using the Support Tool, set the elements indicated below
on the screen.
- Numeral setting input field (numeric key type)
- Touch switch “input key – control”
@ 0 to 9
@ A to F (only for the numeral setting input field of the hexadecimal
display format)
@ ENT or (necessary for confirming the input)
The following keys can be registered if necessary.
@ CLR (for clearing the numeric value being input)
@" (necessary for inputting a negative value)
@ . (necessary for inputting a decimal fraction)
@ CA (for canceling the input)
@ BS (for deleting a character located immediately before the
input cursor)
@ DEL (for deleting a character located immediately after the input
cursor)
@ A, " (for moving the input cursor)
[Operation]
(1) Display the screen where a numeral setting input field is registered.
(2) Input a numeric value using the “input key – control”.
For the procedure for inputting a numeric value, refer to “Inputting operation
using touch switches” (page 520).
Reference: When the screen has only one numeral setting input field, pressing a “control key”
(0 to 9, A to F) automatically starts the input of a numeric value. It is not necessary
to specify the objective numeral setting input field.
(3) Press the ENT key of the “input key – control” or the key to confirm the input.
When the input is confirmed, the input numeric value is stored to a numeral
memory table. Then, the occurrence of a change in the contents of the nu-
meral memory table is notified to the host via the PT status notify area (page
276).
Reference: 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.
