Input of Numeric Values and Character Strings

[Operation]

(2) Specify the objective numeral setting input field using the “input key – control”
(HOME,

For the procedure for specifying the objective input field, refer to “Specifying
the objective numeral setting input field using input key – control” (page 523).
(3) Input a numeric value using the “input key – control”.
For the procedure for inputting a numeric, refer to “Inputting operation using
touch switches” (page 520).
(4) 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 objective input field is shifted before confirming the input, the input numer-
ic value is canceled and the screen returns to the one displayed before the nu-
meric value was input.
- 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.
- 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 next input field is selected as the
objective input field.

from the upper left corner of the screen, the one at the left most position is se-
lected as the objective input field.
