5-8 Numeral Setting
The NT600S has a “numeral setting” function to enable numerical values to be in-
put from the screen. This function inputs numerical values to numeral memory
tables in response to touch switch operations, displays these numerical values on
the screen, and sends them to the host.
This section outlines the numeral setting function and the method for creating the
ten keys required to set numerical values on the screen, and explains how to use
ten keys during operation.
Numeral setting screens cannot be registered as child screens of continuous
screens, In the case of overlapping screens, only one of the screens can be set as
a numeral setting screen.
In order to input numerical values using touch switches, apart from the display
area for the numeral setting, the numeric keys must also be created. For details on
how to create numeric keys, see “Creating Numeric Keys” (page 146).
Ensure the safety of the system before changing the monitor data.
5-8-1 Function of Numeral Keys
Basic Procedure The procedure for numeral setting is as follows.
(1) Input the numerical value using touch switches (numeric keys).
(2) The input numerical value is displayed in the numeral setting area on the
screen.
(3) Confirm the input numerical value (by pressing the [ENT] key); it will be written
to the numeral memory table, and simultaneously notified to the PC/Host.
Numerical values are displayed in
the numeral setting area.

If there is more than one numeral setting area, the one in which the numerical val-
ue is to be input can be selected by using a touch switch (numeric key).
Restrictions on Numerical Value Input and Attribute Setting
Numerical values of up to 8 digits (7 if there is a minus sign) can be input in either
decimal or hexadecimal format.
Decimal input
When the display attribute is set for decimal display, values are input in the deci-
mal format.
- Numerical value range
The range for numerical values that can be input differs according to whether
or not there is a sign display.
