[Operation]
(1) Display a screen where a numeral setting input field is registered.
(2) Press the numeral setting input field where a numeric value is to be input to
specify it as the objective input field.
(3) 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).
(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 event of changing the contents of numeral 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 objective input field is selected.
