4-8 Numeral Setting
The NT20S has a “numeral setting” function to enable numerical values to be input
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.
For details of the actual methods used to ascertain input numerical values at the
PC side, refer to “Notification of Numbers to the PC” on page 188, and “Number
Input Notify” on page 212.
Numeral settings are set during screen creation with the support tool.
Caution: Confirm system safety carefully before changing monitor data.
