Numeral Setting
Types of Numeral Setting
There are two types of numeral setting: the numeric key type, and the thumbwheel
type.
The basic function of these two types is the same, but the screen displays and in-
put methods are different.
A maximum of 50 input fields, including both numeric key and thumbwheel types,
can be registered on one screen.
The thumbwheel type of numeral setting can only be used when using Ver.5 direct
connection with an NT20S-ST121-EV3/ST122-V1.
When a numerical value is input using touch switches to which numeric key func-
tions have been allocated, the input numerical value is displayed on the screen.
On pressing the return key after completing input, the input numerical value is writ-
ten to the numeral memory table and notified to the host.
If there is more than one numeral setting input field, the field in which the input is to
be made can also be selected with the numeric keys.
In order to perform numeric key input, it is necessary not only to create a numeral
setting input field on the screen, but also to create the numeric keys to be used for
input (see page 143).
When using an NT-20S-ST121-EV3/ST122-V1 with Ver.5 direct connection, nu-
merical values are input directly at the numeral setting input field using touch
switches that increment or decrement each of the digits in the display when
pressed. Each time the displayed numerical value is changed, the new displayed
value is written to the numeral memory table and simultaneously notified to the
host.
This means that, when using the Thumbwheel type of numeral setting, all that is
required to input numerical values is to create the numeral setting input field on the
screen.
