Changing Numerals/Character Strings by Pressing a Touch Switch Which Has the “Copy Setting” Func-
tion
This method allows an operator to change the contents of a memory table simply
by operation at the NT31/NT31C. It is also possible to copy data to a numeral set-
ting/character string input field by using this method. With the “Copy Setting” func-
tion, data can only be copied in accordance with the predetermined method.
The touch switch “Copy Setting” function executes copying in the following com-
binations.
Numeral setting input field
Numeral memory table
Numeral setting input field
Character string memory table
Character string input field
Numeral memory table
Copy Source Copy Destination
Numeral memory table
Character string memory table

[Setting]
When creating a screen using the Support Tool, set the “Copy Setting” function for
a touch switch. Specify the copy source and copy destination memory table num-
bers, values and input field, then register them for the screen.
The numbers and values that can be specified are:
- Memory table:
0000 to 1999: Numeral/character string memory table No. (0 to 1999)
- Constant:
−2147483648 to 2147483647
- Input field:
Specify an input field already registered for the screen.
Reference: The range of numeral/character string memory table numbers which can actually
be used depends on the number of numeral memory tables and the character
string tables set in “PT Configuration” − “System” setting at the Support Tool.
[Operation]
(1) Press the touch switch with the “Copy Setting” function to copy data.
Reference: If the contents of the numeral/character string memory table have been changed
by operation at the NT31/NT31C, by using the copy key, etc., this event is notified
to the PT status notify area in the host (page 276).
