Numeral Setting Section 4-8
When the touch switches allocated as numeric keys and system keys on a
numeral setting screen are pressed, no notification is made to the PLC. This
means that when using the NT20-ST128 (RS-232C), the touch switches num-
bered 227 to 255 cannot be used as normal touch switches on a numeral set-
ting screen.
4-8-4 Using Numeric Keys
To input numerical data by using numeric keys, first select the numeral setting
area into which the value is to be input, then input the numerical value by
pressing the appropriate numeric keys.
Selecting the Numeral Setting Area for Data Input
Select the numeral setting area into which the numerical value is to be input
by using either the numeric keys or the system keys.
• Selection with the Numeric Keys
Use the [HOME], [
→
], [
←
], [
↑
] and [
↓
] keys. By using these keys, the cursor
can be shifted between numeral setting areas in the way shown in the fig-
ure below.
Pressing the [HOME] key will shift the cursor to the area whose top left cor-
ner has the smallest XY coordinate sum (the top left numeral setting input
field in the example above).
• Selection with the System Keys
When the and system keys on the touch panel are pressed, the cursor
moves between the numeral setting areas by following the order in which
they were created using the Support Tool.
For example, if three numeral setting areas have been created, the cursor
can be moved between them following the order of creation as follows.
key: 1st area
→
2nd area
→
3rd area
→
1st area
key: 1st area
→
3rd area
→
2nd area
→
1st area
If the “numeral setting” screen attribute is set to “system”, the order of cur-
sor motion when the and system keys are used can be changed. For
details, refer to the NT Support Tool for Windows operation manual (Cat.
No. V061-E1- @ ).
Inputting Numerical Values
Input numerical values using the following numeric keys (touch switches):
numerals (0 to 9, A to F), decimal point (.), sign (+,–), clear (CLR), and return
( ).
When inputting a numerical value that includes a decimal point, input the
integer and decimal fraction separately. First input the integer, then press
the decimal point key (.) and input the decimal fraction.
