S If the objective input field is shifted before confirming the input, the input nu-
Reference:
meric value is canceled and the screen returns to the one displayed before the
numeric value was input.
S When a numeric input is confirmed, the PT checks whether the input is within
the upper and lower (max./min.) limits set for that numeral setting input field. 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 dis-
play before starting the input. In this case, neither writing to a numeral memory
table nor notification to the host is executed.
S If the
key is pressed to confirm the input, the same field remains as the objec-
tive input field even after the previous input has been confirmed. If the ENT key
is used for the confirmation of the input, the objective input field shifts to the
next.
S When NT30/620 compatible mode is being used, the current screen number
occupies the first word of the PT status notify area and the words containing the
updated memory table number and PT status notify bits are shifted down one
word (page 441).
The following describes the procedure for inputting a numeric using a temporary
input field which is registered for a window. The term temporary input field
means a numeric key type numeral setting input field registered for a window. It
is used as a temporary input field before the input is confirmed.
When a temporary input field is used, it is possible to input a numeric value while
leaving a numeric value which was active before the input in the numeral setting
input field on the base screen.
Here, the explanation concentrates on how to use a temporary input field in a
window. For the numeric value input procedure (page 318) and the procedure
for specifying the numeral setting input field (page 322, 324) and for opening the
window (page 325), refer to the explanation for the numeric value input method
given previously.
When creating a screen using the Support Tool, set the elements indicated be-
low that are used to specify the active numeral input field as well as the regular
control keys that are used to input the numeric value.
• Window open key touch switch
Specify the window screen number of the window used for inputting a nu-
meric value.
(Used when opening the window for inputting a numeric value. This opera-
tion is not necessary if the window open function is set for the cursor moving
key.)
• Window close key touch switch
Create the window screen used for the input and register the following elements
for it. (It isn't necessary to register all of the elements listed below. Register just
the required elements in the main screen and window.)
