Reference:
S
If the objective input field is shifted before confirming the input, the input nu-
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 next objective input field is se-
lected.
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.
Inputting Numeric Values Using the Input Key – Control in a Window

handled. For the numeric value input procedure and the procedure for specify-
ing the numeral setting input field, refer to the explanation for the numeric value
